Design Engineer (Electrical) with Resolve to Perform

<p class="article__lead-paragraph">Steerprop&#39;s fit-for-purpose propulsion system will help to maintain environmental performance and provide the manoeuvrability needed for operations in and around deeper offshore power projects.</p>

<p class="article__paragraph">Set to be delivered in 2026, the Fleeming Jenkin will be the world&#39;s largest Cable-Laying Vessel (CLV) to date. By optimizing the propulsion system to be in line with the ship&#39;s operating profile, maritime environmental regulations, and customer requirements, Steerprop has done its part to ensure that the new CLV will also be the world&#39;s cleanest.</p>

<p class="article__paragraph">The Fleeming Jenkin is being built by China Merchants Heavy Industry Haimen (CMHI) and will be owned by Jan De Nul Group. The main propulsion for the Fleeming Jenkin will come from four azimuth thrusters. Manoeuvrability will be enhanced by three tunnel thrusters and two retractable. An additional full main thruster and extensive spares package will also be supplied as part of the contract. In addition to the Fleeming Jenkin, Jan De Nul is also building a second identical vessel with three carousels and a cable-carrying capacity of 28,000 tonnes.</p>

<p class="article__paragraph">The move reflects a confidence in the technology and design competence of Steerprop, according to Juho Rekola, Director, Sales and Project Management, &quot;This is a milestone project for us, and not just because of the technology; we showed that we were able to adapt to various end-customer requirements and be flexible in terms of CMHI&#39;s needs in order to ensure that the building and commissioning phases occur seamlessly. It demonstrates our ability to address the requirements of even the most demanding of applications from within our extended product portfolio.&quot;</p>

<p class="article__paragraph">&quot;This is our first time working with Steerprop. We hope that this cooperation will be smooth and demonstrate its expertise, and we are looking forward to doing more together in the future,&quot; says Tao Chen, CMHI (Jiangsu) Deputy GM.</p>

<blockquote>
<p>Fleeming Jenkin bundles all the cable installation expertise we&#39;ve gained over the past decade. This vessel and the technologies on board are designed by our in-house specialists. We are happy to add to that the expertise of Steerprop in delivering a comprehensive propulsion system for our cable-laying vessel under construction, resulting in high-maneuverable and performant vessel&nbsp;for challenging offshore conditions. We look forward to working together on this project,&quot; says Jan Van de Velde, Director of Newbuilds at Jan De Nul.</p>
</blockquote>

<p class="article__paragraph">Juho Rekola adds that the Fleeming Jenkin demonstrates how Steerprop is committed to fully understanding customers&#39; needs, requirements and expectations. &quot;Ship-owners shouldn&#39;t have to compromize because they&#39;ve been forced to choose a solution straight from a manufacturer&#39;s catalogue. Instead, they should set challenges and expect their suppliers to rise to them. The Fleeming Jenkin is a fine example of how this philosophy can help to shape reality.&quot;</p>

Steerprop Selected to Supply Main Propulsion and Tunnel Thrusters for Canadian Coast Guard Multi-Purpose Vessels Program

<p class="article__lead-paragraph"><strong>While negotiations about a propulsion retrofit for an ASD tugboat are underway, a fit-for-purpose idea comes to light: what if the propulsion solution could accommodate seasonal change &ndash; namely, eliminating the ever-present hassle provided by ice during winter operations?&nbsp;</strong></p>

<p class="article__paragraph">Artemis, one of the longest serving Azimuth Stern Drive (ASD) tugboats in the Alfons H&aring;kans fleet, needed a propulsion boost. <strong>Tuomas Raumanen</strong>, Technical Manager for Turku-based Alfons H&aring;kans, recalls that the company was thinking about various alternatives in the autumn of 2021. The propulsion unit was 40 years old and nearing the end of its life cycle.</p>

<p class="article__paragraph">&ldquo;We knew that a major overhaul would be costly and take a long time to perform. The alternative was getting a new propulsion unit as a retrofit,&rdquo; Raumanen explains.</p>

<p class="article__paragraph">&ldquo;We were also interested to upgrade thrusters to new model with a slipping clutch. Original propulsion units did not have a slipping clutch function and manoeuvring of the tug was sometimes demanding, especially in small harbor basins,&rdquo; he adds.</p>

<p class="article__paragraph">Alfons H&aring;kans, one of the leading towage and salvage companies in the Baltic Sea, asked around for offers. The company soon got into talks with Steerprop, a leading designer and manufacturer of propulsion systems for the most demanding applications and toughest conditions, who had just collaborated with the company regarding the very same ship.</p>

<p class="article__paragraph">&ldquo;Steerprop had just modernized and upgraded the control system on Artemis and we had good relationship,&rdquo; explains Raumanen.</p>

<p class="article__paragraph">&ldquo;As a consequence, we decided to make a deal for the new propulsion unit retrofit with them.&rdquo;</p>

<h3 class="article__heading--h3"><strong>Dealing with ice </strong></h3>

<p class="article__paragraph">So far, everything was proceeding as it regularly would. At this time, however, Raumanen started thinking: could the Steerprop delivery scope be modified somehow to take care of a persistent problem that tugboats keep facing in the winter?</p>

<p class="article__paragraph">&ldquo;The propulsion units feature nozzles that get jammed up with crushed ice during winter,&rdquo; Raumanen explains, adding that, for example, most port areas are plagued with just such ice.</p>

<blockquote>
<p class="article__paragraph">The ice will get stuck in the nozzles and propulsion performance will drop dramatically. Furthermore, emptying the ice from the nozzles is a time-consuming job that is not exactly easy to pull off.</p>
</blockquote>

<p class="article__paragraph">Raumanen challenged the Steerprop design team to come up with a solution: instead of welded-in nozzles, would a more &ldquo;mobile&rdquo; system work? That way you could take away the nozzles in the wintertime when ice becomes an issue &ndash; and simply put them on again after winter.</p>

<h3 class="article__heading--h3"><strong>Rising to the challenge</strong></h3>

<p class="article__paragraph"><strong>Juho Rekola</strong>, Director, Sales and Project Management, from Steerprop says that the design team immediately saw the value in the idea. &ldquo;Nozzles filling with crushed ice is a potentially a very serious safety issue, not to mention the drop in performance level. We were eager to tackle this challenge,&rdquo; Rekola says.</p>

<p class="article__paragraph">A fit-for-purpose concept begun to take shape soon. Instead of welding the nozzles in place, one could bolt them in &ndash; and remove them at your leisure. The trick, however, was that you would have to do it under water.</p>

<p class="article__paragraph">&ldquo;I contacted local DG Diving Group who have lots of experience from demanding projects &ndash; and they were confident that they could get it done,&rdquo; says Tuomas Raumanen.</p>

<p class="article__paragraph">Next up, the Steerprop professionals came in to install the propulsion unit, but the question remained: will the underwater operation bring the desired end result? The moment of truth finally arrived at the end of February, 2024, as it was time to remove the nozzles &ndash; as well as replace the &ldquo;summertime propeller&rdquo; with a &ldquo;winter propeller&rdquo; &ndash; in the freezing-cold water. Steerprop&rsquo;s most experienced technician stood by on the pier, ready to offer assistance.</p>

<figcaption><span class="article__figure__caption">Job well done! The concept with dismountable nozzles means that Artemis can be used also in the hardest ice conditions during wintertime.</span></figcaption>
</figure>

<p class="article__paragraph">The switch would take time even under best of circumstances. &ldquo;If you do this same procedure on dry dock, it&rsquo;ll take 4-5 days to perform. We couldn&rsquo;t know in advance, how fast things would happen under water,&rdquo; Raumanen says. However, with a dry dock certain extra expenses are known: for example, reserving and getting the vessel to available drydock takes time and runs up the cost.</p>

<h3 class="article__heading--h3"><strong>Beneath the surface</strong></h3>

<p class="article__paragraph">Everybody was most pleasantly surprised when the diving team pulled off the job in four days. &ldquo;The Steerprop technician remarked that most dry docks couldn&rsquo;t move that fast,&rdquo; grins Raumanen.</p>

<p class="article__paragraph">&ldquo;And think of the conditions: for example, managing 10 mm nuts with your bare hands in Baltic Sea in February is not for everybody,&rdquo; Raumanen gives credit to the diving team which numbered 2-3 divers, depending on the work phase.</p>

<p class="article__paragraph">Juho Rekola agrees: the divers really did the &ldquo;heavy lifting&rdquo; here, making it possible to pursue a wild idea to its fruition. &ldquo;The collaboration in this project was outstanding throughout,&rdquo; he adds.</p>

<p class="article__paragraph">All that hard work paid off. Raumanen reports that the feedback from Artemis, back upon the waves in March, has been only positive.</p>

<blockquote>
<p class="article__paragraph">It was great to see how well everything has been working, and the operability of the propulsion unit remains solid. This concept with dismountable nozzles means that we can use Artemis also in the hardest ice conditions during wintertime which was not possible with original thruster units.</p>
</blockquote>

<p class="article__paragraph">The tugboat will return to &lsquo;summer mode&rsquo; in April, as the nozzles are installed back in by divers.</p>

<h3 class="article__heading--h3"><strong>Solve any problem</strong></h3>

<p class="article__paragraph">Looking back at the entire project, Raumanen says that Steerprop &ndash; once again &ndash; gave an impressive showing with its flexibility and ability to think outside the box.</p>

<blockquote>
<p class="article__paragraph">Furthermore, when we ask, can this be done, the answer is never &lsquo;no&rsquo;. Instead, they say &lsquo;let us get back to you&rsquo; and figure out the best way forward,&nbsp;says Raumanen.</p>
</blockquote>

<p class="article__paragraph">The &lsquo;nozzle on, nozzle off&rsquo; concept is now included in the retrofit scope of another Alfons H&aring;kans vessel: tugboat Apollon will be fitted the same way, reveals Raumanen.</p>

<p class="article__paragraph">&ldquo;We&rsquo;re happy to expand on a winning concept,&rdquo; he adds.</p>


While negotiations about a propulsion retrofit for an ASD tugboat are underway, a fit-for-purpose idea comes to light: what if the propulsion solution could accommodate seasonal change – namely, eliminating the ever-present hassle provided by ice during winter operations? Steerprop and Alfons Håkans combined forces in pursuit of a truly out-of-the-box propulsion solution.     

Tugboat Artemis tackles ice woes with fit-for-purpose innovation 

<p class="article__lead-paragraph"><em>In the realm of seafaring vessels, noise generated by propulsor systems manifests in two distinct forms: onboard noise, perceptible within the confines of the vessel, and underwater radiated noise (URN), which resonates beneath the surface. While historical attention has centered on onboard noise, URN has emerged as a growing concern in recent decades. At Steerprop, we&#39;ve embraced a proactive ethos, adopting a &quot;design for low noise&quot; strategy that integrates noise reduction considerations across all stages of design and manufacturing. This approach not only benefits onboard comfort but also mitigates the impact on URN.</em></p>

<h3 class="article__heading--h3">The Impact of URN</h3>

<p class="article__paragraph">While onboard noise may disrupt passengers or crew members, URN poses a more significant threat to fragile underwater ecosystems. Sensitive regions like the Arctic and Antarctic are particularly susceptible to URN disturbances, potentially impacting marine life and habitats. Recognizing this, entities like the Vancouver Fraser Port Authority have instituted incentives for ships meeting URN criteria, mindful of the well-being of local whale and mammal populations. Worldwide, fishing vessels and research ships alike are battling with URN&#39;s effects, from altering fish behavior to compromising underwater signal measurements. Classification societies have responded by introducing &quot;quiet class&quot; notations, initially addressing onboard noise but increasingly encompassing URN considerations. While URN classification remains relatively limited, industry trends suggest a growing emphasis on incorporating URN targets into new vessel designs, possibly culminating in future regulatory mandates.</p>

<h3 class="article__heading--h3">The Quest for Silence</h3>

<p class="article__paragraph">To meet the demand for vessels with reduced URN levels, designers and shipyards must carefully address all major noise sources. A tailored approach, customized to each vessel&#39;s design and operational requirements, is paramount. Propulsion systems represent a focal point, with efforts concentrated on minimizing noise from propellers and drive trains. Propeller-induced noise stems from water cavitation, while drive trains contribute mechanical and electrical noise. Steerprop&#39;s contra-rotating propulsion (CRP) system tackles both fronts by employing dual propellers with lower loading to mitigate cavitation, alongside LM units that integrate a permanent magnet motor to reduce drive train noise. Moreover, advancements in propulsion technology, such as the CRP, not only enhance efficiency but also inherently curb URN emissions by minimizing cavitation.</p>

<h3 class="article__heading--h3">Advancing Noise Control</h3>

<p class="article__paragraph">Beyond product development, collaborative research endeavors are instrumental in deepening our understanding of noise dynamics and mitigation strategies. Through partnerships with organizations like Finland-based ATA Gears and Luode Oy, we&#39;ve delved into noise excitation mechanisms and conducted comprehensive noise measurements on various vessels. Despite progress, challenges persist, magnified by the scarcity of publicly available URN data. However, our commitment to a holistic noise control approach remains steadfast, fueled by ongoing research and an unwavering dedication to meeting the evolving needs of our clients.</p>

<h3 class="article__heading--h3">Enhancing Tunnel Thrusters for Low URN Levels</h3>

<p class="article__paragraph">In our pursuit of low URN levels, tunnel thrusters represent another vital consideration, not only for their contribution to URN but also for their impact on onboard noise during maneuvering. Acknowledging the hydrodynamic complexities inherent in tunnel thrusters, we&#39;re actively exploring optimization strategies, including fine-tuning propeller geometry and implementing innovative solutions to minimize noise emissions. Our objective is clear; to ensure tunnel thrusters operate with the utmost silence without compromising performance.</p>


In the world of seafaring, noise from propulsor systems comes in two types: onboard noise felt within the vessel, and underwater radiated noise (URN) below the surface. Steerprop takes a proactive approach by prioritizing noise reduction in design and manufacturing.

Focusing on minimizing underwater radiated noise

In the world of seafaring, noise from propulsor systems comes in two types: onboard noise felt within the vessel, and underwater radiated noise (URN) below the surface. While past focus has been on onboard noise, URN has become a more significant concern. Steerprop takes a proactive approach by prioritizing noise reduction in design and manufacturing, benefiting onboard comfort and minimizing URN impact.

<p class="article__lead-paragraph">This past summer Steerprop had the opportunity to get to know Ilona Sj&ouml;blom and Markus Taulu, two out of many Master&rsquo;s degree students that worked with us in various summer trainee positions.</p>

<p class="article__paragraph">Ilona, a 22-year-old Environmental Engineering student from Oulu University, worked as an intern in the QHSE team, and Markus, a 25-year-old from Eurajoki studying Computer Engineering at Lappeenranta University of Technology, landed a trainee position in the IT team. Let&rsquo;s hear from them what their expectations were at the start of the summer, and how well they were met during their trainee period.</p>

<p class="article__paragraph">Ilona&rsquo;s goal for the summer was to get to work with tasks that related to her field of studies: &quot;When I found the QHSE internship opening at Steerprop, I knew immediately it would match my interests and complement my studies. I also wanted to learn more about the marine industry and about manufacturing.&quot;</p>

<p class="article__paragraph">Markus, who worked with the project team at Steerprop last summer, was looking for a deeper dive into the IT field this summer: &quot;This time, I knew what to expect. Unlike last year, I was already familiar with people, places and practices. Last year I gained experience in project teamwork, but I also collaborated extensively with Steerprop&#39;s IT team, so I already had some idea of the work involved for this year.&quot;</p>

<figure class="article__figure">
<div class="article__figure__placeholder"><img alt="" src="https://flockler.com/thumbs/sites/13425/ilona_1-2caf5c9a-3baf-4df6-a836-d4e5f9a0db69_s600x0_q80_noupscale.jpg" /></div>

<figcaption><span class="article__figure__caption">Ilona Sj&ouml;blom, Environmental Engineering student from Oulu University, worked as an summer intern in the QHSE team. Ilona&rsquo;s goal for the summer was to get to work with tasks that related to her field of studies.</span></figcaption>
</figure>

<p class="article__paragraph">Their summer work at Steerprop has supported Markus&rsquo; and Ilona&rsquo;s studies by giving many practical insights to support their more theoretical studies. The QHSE tasks Ilona worked with were diverse; she became familiar with different standards, carbon footprint calculations, quality documents, occupational safety matters etc.</p>

<blockquote>
<p>The best part of the summer was actually getting the opportunity to utilize what I&#39;ve learned at the university. The tasks were sometimes quite challenging, but rewarding, as that was when I actually learned the most, Ilona&nbsp;says.</p>
</blockquote>

<p class="article__paragraph">Markus, on the other hand, says the most interesting part of the summer job was gaining experience in many different IT-related matters, although he also felt it was just scratching the surface of the complexity of working with IT:</p>

<p class="article__paragraph">&quot;I worked as a member of the IT team, and even as the sole member when my superior was on summer holiday. My tasks involved a lot of work with devices, creating policies, instructions and guides, and helping other employees with various IT issues. I&#39;ve always known that IT is somewhat &rdquo;mysterious&rdquo;, but working in IT this summer showed how truly enigmatic it can be. Things break and fix themselves and sometimes when faults are found, fixing them can be extremely challenging. However, it was always gratifying when I managed to fix a colleague&#39;s IT problem and received positive feedback. That always brought a smile to my face,&quot; Markus says.</p>

<p class="article__paragraph">At Steerprop Ilona and Markus found a supportive working community that helped them grow and gain practical work experience. Their experiences have supported their studies and have influenced their perspectives on future career choices and aspirations.</p>

<p>The highlight of Ilona&rsquo;s summer was getting the opportunity to write her Master&rsquo;s thesis for Steerprop:</p>

<p class="article__paragraph">&quot;There were many great moments during the summer, but the best one was when I found out I&rsquo;m going to be able to write my thesis on a subject that genuinely interests me and that I had spent a lot of time on during the summer. I&#39;m also very grateful to my supervisor who has taught me so much and who gave me this opportunity!&nbsp;This past summer taught me a lot about the kind of work I want to do in the future.

<p class="article__lead-paragraph">M/V Rem Energy is a champion for Green Transition: The Construction Service Operation Vessel (CSOV) performs demanding maintenance work at wind farms on the North Sea, using Steerprop&rsquo;s contra-rotating propellers to achieve operational excellence.</p>

<p class="article__paragraph">The Norwegian marine sector player Rem Offshore has a long-term charter contract with the German company Siemens Gamesa Renewable Energy for the servicing of two windfarms &ndash; Global Tech 1 and Borkum West 1 &ndash; which are located roughly 200 miles from the German port of Bremerhaven.</p>

<p class="article__paragraph"><strong>Emil Ganchev</strong> became the captain of M/V Rem Energy in March 2023 &ndash; or rather, he is taking turns with another captain upon the seas. &ldquo;We have a six-weeks-in, six-weeks-out rotation system,&rdquo; he explains.</p>

<p class="article__paragraph">Captain and his crew &ndash; numbering 23-25 seasoned sailors &ndash; make regular rounds to the offshore wind farms, unloading provisions that make sure that the wind farms&rsquo; operation can proceed without a hitch. Working on the North Sea, often in rough weather, you need a tested &ldquo;work horse&rdquo; to get the job done.</p>

<p class="article__paragraph">M/V Rem Energy, which was developed in close cooperation with designer HAV Design AS and the client, has several inventive features which meet future requirements for zero emissions and optimal workflow. Built at the Norwegian shipyard Green Yard Kleven in 2021, the ship is a great example of the client, designer team and the yard working together for great results.</p>

<h3 class="article__heading--h3"><strong>Propulsion performance to handle rough seas</strong></h3>

<p class="article__paragraph">This &ldquo;green champion&rdquo; is also equipped with environmentally friendly propulsion technology: Rem Energy features two 2,100 kW Steerprop contra-rotating propellers (CRP). The propellers feature push-pull configuration that is designed to meet the toughest conditions, while combining the excellent maneuverability of azimuth propulsors with the top efficiency of the CRP technology.&nbsp;Per vessel specifications, DP operation is listed at 6,9 m3 /d at position keeping.</p>

</figure>

<p class="article__paragraph">Captain Ganchev explains that thanks to the vessel&rsquo;s propulsion system, Rem Energy is a good fit for demanding DP (Dynamic Positioning) operations. A dynamic positioning system automatically maintains a vessel&rsquo;s position and heading, by using its own propellers and thrusters.</p>

<blockquote>
<p class="article__paragraph">&ldquo;The propulsion system is very reliable. Working together with the thrusters, position keeping with the ship is just perfect,&rdquo; says the captain.</p>
</blockquote>

<p class="article__paragraph">Ensuring the crucial maintenance of offshore wind farms in the North Sea, one certainly needs that dynamic positioning edge to win the day. Steerprop contra-rotating propellers can deliver this in spades:</p>

<p class="article__paragraph">&ldquo;Obviously, we have to move with great precision around the wind farms. With our system, we can work in any direction, which is a great enabler in our line of work,&rdquo; he says.</p>

<h3 class="article__heading--h3"><strong>Great user experience makes a difference </strong></h3>

<p class="article__paragraph">Captain Ganchev has been sailing the seas since 2003, having been in the service of the offshore industry since 2009. Chief Engineer of Rem Energy, <strong>Iliyan Trayanov</strong>, has been on the seas even longer, having started his career back in 1990. They both agree that in addition to great performance and reliability, the Steerprop CRP propulsion system is also pretty handy to use.</p>

<p class="article__paragraph">&ldquo;The Steerprop system is very user-friendly, we&rsquo;ve had no problems operating it,&rdquo; say the men in unison.</p>

<p class="article__paragraph">Maintenance of the propulsion system is also quite straightforward and hassle-free. &ldquo;We have scheduled maintenance upon dry docking. When we are at sea, there is also Remote Assistance available from Steerprop if there are any problems,&rdquo; says the captain, adding that they haven&rsquo;t needed it yet.</p>

<p class="article__paragraph">In addition to Rem Energy using Steerprop technology, company&rsquo;s vessels Rem Mistral, Rem Art, Rem Star, Rem Arctic, Rem Insula and Rem Cetus are all equipped with the same system.</p>

<h3 class="article__heading--h3"><strong>Future-proof and ready for green hydrogen </strong></h3>

<p class="article__paragraph">The sustainable angle is important for Rem Offshore and Siemens Gamesa alike. Upon announcing the contract, <strong>Fredrik Rem&oslash;y</strong>, the former CEO of Rem Offshore, said that the company wants to continue supporting Siemens Gamesa in their quest for optimal solutions for the offshore wind industry, noting that Rem Offshore has dedicated &ldquo;large resources for growth in renewables&rdquo;.</p>

<p class="article__paragraph">Wholly in tune with this, Rem Energy stands ready to meet the future demands for zero emissions: it is capable of operating by using a battery and fuel cell system, powered by green hydrogen.</p>

<p class="article__paragraph">&ldquo;The vessel has that capability built-in, but it is not in use as of yet,&rdquo; says Ganchev. In fact, Rem Energy is the first hydrogen battery-ready vessel utilized by Siemens Gamesa.</p>

Steerprop delivers propulsion edge to Rem Energy

<p class="article__paragraph">Krista Kuusela, 25 years old, from Rauma and Erik Korhonen, 24, originally from Oulu, worked with us as trainees in the summer of 2023. Both are now in their final stages of studies; Krista is studying to become an electrical and automation engineer at Satakunta University of Applied Sciences and Erik is studying at the University of Oulu, majoring in mechanical engineering with a focus on machine design. We have spoken to them to hear more about how they experienced working at Steerprop during this past summer.</p>

<p class="article__paragraph">Krista had been looking for a suitable summer job in electrical design, an area in which she hadn&rsquo;t worked previously. She had, however, some experience from working in the maritime industry previously, and thanks to the summer job at Steerprop, she got to consider maritime regulations a bit more from an electrical angle and learned to understand what standards needed to be applied, and how:</p>

<blockquote>
<p>My goal was to accumulate skills and experience in the realm of design, I expected to learn something new, and these expectations were very much fulfilled &ndash; I have learned a lot this summer!</p>
</blockquote>

<p class="article__paragraph">Just as Krista, Erik was also looking for practical work experience within his field of studies, i.e. in the field of mechanical design:</p>

<p class="article__paragraph">&quot;Before sending in my job application, I had never heard of Steerprop. After researching their website, I got the impression that quality really matters at this company. This impression proved to reflect the reality at Steerprop very much; things aren&#39;t done just &ldquo;well enough&rdquo;, but as well as they possibly can be.</p>

<blockquote>
<p>My goal was to gain practical experience in the field of mechanical design, and my expectations were certainly both met and exceeded. I was surprised by how much I actually got to do. I&#39;ve heard stories about summer interns at other companies that only got to run someone else&#39;s errands. At Steerprop, that really wasn&#39;t a concern; I could independently handle my tasks within projects.</p>
</blockquote>

<p class="article__paragraph">Both Erik and Krista were pleasantly surprised by how diverse their work during the summer was. They both got to work independently within various design projects and with different tasks. Krista conducted small-scale research, created guidelines for production, and provided instructions related to electrical safety. Erik, for his part, handled various tasks in mechanical design, designing components and tools, performing calculations and creating drawings.</p>

<figure class="article__figure">
<div class="article__figure__placeholder"><img alt="&quot;I do see the potential to work in the marine industry, perhaps in propeller design, says Krista Kuusela." src="https://flockler.com/thumbs/sites/13425/krista_1-6c0e4599-dabc-497a-b7c5-742fbfc8238f_s600x0_q80_noupscale.jpg" /></div>

<figcaption><span class="article__figure__caption">&quot;I do see the potential to work in the marine industry, perhaps in propeller design, says Krista Kuusela.</span></figcaption>
</figure>

<p class="article__paragraph">&quot;It was surprising how extensive the tasks were; I didn&#39;t expect the work to be so diverse, which was, of course, a very positive experience, Krista says.</p>

<p class="article__paragraph">&quot;The best part was that my work was needed and put to use, allowing me to delve deeper into electrical standards and to gain a broader understanding of electric motors,&quot; she continues.</p>

<p class="article__paragraph">One of Erik&rsquo;s main takeaways from the summer was noticing how well the theoretical studies at university corresponded to actual practical work. Nevertheless, he also learned a lot during the trainee period. Looking back at some of the most beneficial learnings, he explains:</p>

<p class="article__paragraph">&quot;Perhaps the best part was learning through independent work. From a future designer&#39;s perspective, the most interesting aspect was getting a closer look inside devices, understanding what&#39;s there, and how everything operates&quot;, he says.</p>

<figure class="article__figure">
<div class="article__figure__placeholder"><img alt="Erik Korhonen continues to work part-time at Steerprop remotely from Oulu, alongside his studies." src="https://flockler.com/thumbs/sites/13425/erik_1-9de17805-7e38-4339-9bd1-92398515c9b4_s600x0_q80_noupscale.jpg" /></div>

<figcaption><span class="article__figure__caption">Erik Korhonen continues to work part-time at Steerprop remotely from Oulu, alongside his studies.</span></figcaption>
</figure>

<p class="article__paragraph">Almost everything learned during the summer will surely be beneficial. Especially the manufacturing stages of components, their manufacturability and assembly sequences provided new insights that have not been extensively covered within my studies. Additionally, I hadn&#39;t done much project-oriented work before, but now I have a solid foundation in that area too.</p>

<p class="article__paragraph">Both Krista and Erik highly appreciated the positive work environment at Steerprop, the supportive colleagues, and the learning opportunities their respective roles provided. They have both gained valuable insights that they believe will be useful in their future careers.</p>

<p class="article__paragraph">&quot;The work environment and colleagues were really pleasant. My supervisor was fantastic, providing guidance throughout the summer, not just at the beginning of the internship. The overall atmosphere in the office was calm and relaxed, making work enjoyable&quot;, Krista says.</p>

<p class="article__paragraph">&quot;It was a very nice summer in terms of work. Everyone was approachable, always ready to help. The team spirit was excellent; conversations flowed, and everyone made sure no one was left behind when heading out for lunch or coffee. We also spent time together outside work, so I guess my colleagues now count as new friends&quot;, Erik adds.</p>

<p class="article__paragraph">Neither Erik nor Krista have definite plans for the future, except for finishing their studies, but both could, based on their positive experience at Steerprop, consider a career within the maritime industry:</p>

<p class="article__paragraph">&quot;I haven&rsquo;t thought about or decided on my future career path; I&#39;m interested in everything in my field of studies. However, I do see the potential to work in the marine industry, perhaps in propeller design&quot;, says Krista.</p>

<p class="article__paragraph">&quot;I&#39;ll continue working part-time at Steerprop remotely from Oulu, alongside my studies. Other than that I haven&rsquo;t really had the time to think any further into the future. However, my experience this summer has definitively confirmed my initial thoughts about wanting to work with cutting-edge product development. Whether it&#39;s in the maritime industry, forest industry, or something in between, time will tell&quot;, Erik continues.</p>

<p class="article__paragraph">All in all, Krista and Erik had a rewarding and enriching summer. At Steerprop they found a supportive environment for professional growth. Their experiences were characterized by meaningful work, a positive workplace culture, and the opportunity to bridge theoretical knowledge with practical application.</p>

A summer at Steerprop – an opportunity to bridge theoretical knowledge with practical application

A summer at Steerprop links theory to practice

A summer at Steerprop – an opportunity to bridge theoretical knowledge with practical application.

<p class="article__lead-paragraph"><strong>If you operate icebreakers, high-ice-class cargo ships, LNG-carriers or offshore vessels designed for independent operation, you will want to handle your vessels safely through the harshest ice conditions and Polar Code areas. Today&rsquo;s modern icebreakers and icebreaking cargo vessels are typically equipped with azimuth propulsors, which is a very effective proven technology. Steerprop&rsquo;s unique azimuth solutions take reliability and efficiency to an entirely new level with a fuel economy that saves costs and reduces emissions.</strong></p>

<p class="article__paragraph">In recent years, new Arctic shipping routes, such as the Northwest Passage and other Arctic areas, have become viable for merchant shipping. These new routes are causing an increasing demand for icebreaking and ice management vessels. In addition to supporting commercial shipping, icebreakers provide important links to remote areas in the northern regions through the resupply of goods. Another critical task for icebreakers is to enable supply chains, via ships calling at ports in Polar Code areas as well as in regions with cold winters when ice is a threat to both vessels and harbors, for example, in the Great Lakes &ndash; the St. Lawrence Trade Corridor in Canada and the United States.</p>

<h3 class="article__heading--h3"><strong>Ice management is the key</strong></h3>

<p class="article__paragraph">The key to keeping fairways and harbors clear is ice management. Operating in ice conditions is either done independently with an ice-classed vessel or through assistance from an icebreaker. At Steerprop, ice management is a way to handle ice-covered seas and waterways using azimuth thrusters, in other words, breaking ice, clearing ice ridges, opening shipping routes, breaking up ice around structures (e.g., oil rigs or wind farm construction sites) and ensuring that ports remain unrestricted by ice.</p>

<p class="article__paragraph">Solutions are already available that can turn an icebreaker, for example, into a multipurpose ice management vessel. Today, azimuth propulsors are the industry standard for icebreaking vessels. Azimuth propulsors are efficient, and especially their ability to direct the vectored slipstream from the propeller in a full 360 degrees is a game changer. This allows a vessel to use the thrust itself not only to open and widen fairways but also to clear ice ridges and free merchant vessels stuck in ice, as well as protect offshore installations or other physical assets from ice pressure.</p>

<h4 class="article__heading--h4"><strong>CRP vs. single propeller propulsors</strong></h4>

<p class="article__paragraph">The propulsion system in modern icebreakers is typically based on azimuth propulsion technology, which has proven to be very effective for icebreakers and icebreaking cargo vessels. Since any lack of propulsion power can easily cause a ship to become stuck, the propulsion systems used must be reliable, flexible, redundant, maintainable as well as possess high power-to-weight and power-to-space ratios.</p>

<p class="article__paragraph">Steerprop is constantly developing propulsion technology that improves overall efficiency. Contra-rotating propulsion (CRP) technology meets the most challenging customer needs. Steerprop&rsquo;s dual-end contra-rotating propellers (CRP) in a push-pull configuration allows for high maneuverability, higher bollard pull/DP-thrust compared to single open propellers, outstanding ice management capabilities and low emissions due to good fuel economy. The power range is from 900 kW to15,000 kW.</p>

<h4 class="article__heading--h4"><strong>Azimuth CRP propulsors &ndash; the ideal choice for icebreakers </strong></h4>

<p class="article__paragraph">Ships operating in ice and Arctic conditions often rely on the width of the channel opened by the icebreaker. Since cargo today is transported using increasingly larger and thus wider merchant ships, the larger beams mean that icebreakers must open channels wider than the width of the icebreaker itself. This problem can be solved using azimuth propulsors.</p>

<p class="article__paragraph">Azimuth propulsors can always be directed in the desired direction to clear ice. Therefore, they can provide a wider channel than the icebreaker&rsquo;s width. But as Figure 1&nbsp;illustrates, Steerprop&rsquo;s CRP can make an even wider channel. With its sophisticated hydrodynamic design of the underwater parts, the CRP creates a narrower and more powerful slipstream behind the propulsor (wake side) than a single propeller in pull configuration; hence, the stream from the CRP reaches further using the same propulsor power.</p>

<figure class="article__figure">
<div class="article__figure__placeholder"><a class="article__figure__link" data-type="image" href="https://flockler.com/thumbs/sites/13425/dia1_valid-1fcad526-7f7c-450d-a197-b7811ba6e5b7_s1800x0_q80_noupscale.jpg" target="_blank"><img alt="Figure 1.

<figcaption><span class="article__figure__caption">Figure 1. Channel widening using propeller wash.</span></figcaption>
</figure>

<p class="article__paragraph">In other words, if the stream is directed toward the ice, the ice formation will break up at various distances depending on the power and thickness of the ice field. (See Figure 2) However, since the CRP stream is more concentrated than a single-pull propeller, the effect extends further. The benefits for icebreakers are that they are able to open wider channels or have an extended impact on ice management by exercising prop wash (clearing ice).</p>

<h3 class="article__heading--h3"><strong>Remarkable 50% increase of speed in brash ice </strong></h3>

<p class="article__paragraph">Steerprop conducted a series of ice model tests at Aker Arctic Technology&rsquo;s ice laboratory in Finland to gain more data to verify the benefits of CRP propulsors. The ice basin tests compared CRPs against traditional single-propeller azimuth propulsors currently used in ice-going applications.</p>

<p class="article__paragraph">The results show that in bollard configurations, CRP provides a higher thrust of approximately 10% using the same power, or the same thrust using 15% lower power when compared to a single propeller of the same diameter. The CRP can benefit several applications &ndash; from dedicated icebreakers and Arctic cargo ships to tankers and ice-going offshore support vessels. The net thrust of the CRP was 10-17% higher than a single-pull propeller with the same power.</p>

<blockquote>
<p><em>Tests showed that the speed in brash ice could be increased by an impressive 50%</em></p>
</blockquote>

<p class="article__paragraph">In addition to icebreakers, cargo ships designed to operate independently in polar ice conditions could typically benefit from Steerprop&rsquo;s CRP solution. The tests showed that ice resistance can be reduced by approximately 10% in level ice, and the speed in brash ice was increased by an impressive 50%. The ridge penetration time was reduced by around 50%.</p>

<p class="article__paragraph">Previously, icebreaker operators often had to compromise regarding bollard pull/icebreaking thrust and free-running efficiency when choosing between an ice-class propeller (with an inferior propulsive performance) or a non-ice-class propeller. An ice-class propeller requires high propeller loading enabled by large blade areas and high hub ratios, whereas ducted propeller configurations, usually required for high bollard pull, present challenges with ice-clogging. Steerprop&rsquo;s solutions are clog-free and provide superior performance in Arctic conditions, thus eliminating compromises and challenges.</p>

<h3 class="article__heading--h3"><strong>Condition monitoring ensures reliability</strong></h3>

<p class="article__paragraph">There are evident risks with shipping in ice and Polar Code areas. Operating in such inaccessible and vast regions is always difficult and dangerous. Therefore, the harsh conditions and remoteness of these areas create a demand for high reliability to meet risk management standards.</p>

<p class="article__paragraph">Shipowners can achieve the highest possible reliability through enhanced predictability using additional tools, such as condition monitoring and predictable maintenance. Condition monitoring of the propulsion equipment allows crew members to follow machinery trends and detect deviations that could affect the propulsion system in the future.</p>

<p class="article__paragraph">Condition monitoring is available at different levels, from basic trend follow-up and deviation detection to clear value-adding in-depth professional analysis by Steerprop&rsquo;s experts. In practice, this means that condition monitoring can cover the entire propulsion system, including vibration, along with signals and alarms from the control system using advanced AI and machine learning techniques. Having a remote online connection enables Steerprop experts to analyze data from the propulsor almost in real-time and notify a crew well ahead of any development that may cause future disturbances. These features are also available as retrofit installations in older units.</p>

<p class="article__paragraph">In addition, condition monitoring is likely to generate maintenance cost savings. By taking a proactive approach, the need for a complete overhaul may be postponed based on the condition of the propulsion equipment. Furthermore, this helps with maintenance budgeting since maintenance costs can be predicted and surprises avoided.</p>

<p class="article__paragraph">The critical conditions and isolation in Polar Code areas require high reliability to meet risk management standards. In icebreakers and ice-class vessels, pushing and pulling have traditionally been the preferred propulsor type. However, Steerprop&rsquo;s contra-rotating propulsion (CRP) technology offers unique ice management capabilities and ultimate reliability.</p>

<p class="article__paragraph">Are you looking for the best ice management capabilities? Steerprop&rsquo;s experienced propulsion experts are ready to help you find the most efficient propulsion solution for your icebreaker or ice-going vessel.</p>


If you operate icebreakers or high-ice-class vessels, ensuring safe navigation through harsh ice conditions is paramount. Steerprop's azimuth propulsors, backed by proven technology, redefine reliability and efficiency, offering fuel economy benefits that cut costs and reduce emissions.

</blockquote>

<p>The reliability of our propulsion units is essential. They are used on vessels involved in very critical operations, such as ice management, on icebreakers, oil platforms, wind farm maintenance vessels and cruise vessels, where any interruption can cause huge losses. To maximize the reliability of the propulsion units, our technical department needs to consider the challenging conditions in both open and icy waters in their calculations. For example, different kinds of load cases need to be considered and propulsor tooth contact patterns need to be designed to be ideal for every specific condition and situation.</p>

<p>To ensure lowest lifecycle costs, we have developed Steerprop Care, our condition monitoring service, which enables us to support our customers in their operations and ensure operational quality throughout the lifetime of the vessel. For example, by monitoring the life of the propulsor unit&rsquo;s power transmission line, unnecessary downtime and maintenance can be avoided and both time and money can be saved. Steerprop Care turns unplanned disturbances into planned service.</p>

<h2 class="article__heading--h2">Close cooperation to achieve the very best</h2>

<p>To be able to add true value to our customers&rsquo; business, we are always open to new ideas and developments. This requires close cooperation with our component suppliers and manufacturers, listening to their research projects, being curious and continuously learning more.</p>

<p>The maritime industry also presents new challenges. When customers ask eg. for larger propulsors, it calls for complex considerations when it comes to material properties and manufacturability. By working in close cooperation with the world&rsquo;s leading component manufacturers, we can meet these industry challenges. For example, cooperation with companies that specialize in gears has helped us to achieve the proper hardening depths for gear sets. In this way, we can shape the lower body and get even greater results in efficiency.</p>

<blockquote>
<p paraeid="{6a60d794-6206-468b-8fb7-78f1aa9991f8}{52}" paraid="337738946">Only the best is good enough for us. We do not make any compromises when it comes to reliability. As we are determined to create even more efficient propulsion systems for the market, we concentrate on optimizing the shape of underwater parts to minimize flow resistance and take greater advantages of the contra-rotating propellers. In our optimization studies, we use model tests and CFD calculations.</p>
</blockquote>

<p>As part of our commitment to developing propulsion technology that improve overall efficiency, we have developed the contra-rotating propulsion (CRP) technology ECO product line. The whole propulsor is pressure lubricated to lower mechanical losses compared with the commonly used oil bath lubrication technology. To ensure the reliability of the propulsion units, they are subject to comprehensive factory tests where the functionality of the system is tested and verified.</p>

<p>Another big development is our Steerprop LM unit, which uses an integrated permanent magnet (PM) motor that offers much better efficiency compared to a traditional induction electric motor. Moreover, by replacing our upper gear with an LM motor, we get more room in the ship for other components and we can avoid upper gear excitations in the ship hull, which is especially important for cruise vessels.</p>

<h2 class="article__heading--h2">Teamwork all the way</h2>

<p>Resolving the challenges in the market and delivering on our promise is not a one-person process or project. To succeed in performing the very best solutions for our customers, it is important to be surrounded by visionaries and brilliant individuals that work together for a common goal.</p>

<p>Steerprop&rsquo;s R&amp;D department has highly motivated in-house experts from many different fields. Along with external specialists, we work closely together to produce outstanding propulsion solutions. We do our very best every day, bringing skills from mechanical design and analyzing, hydraulics, hydrodynamics, materials, and sealing systems to create superior products to meet our customers&rsquo; needs.</p>

<blockquote>
<p paraeid="{6a60d794-6206-468b-8fb7-78f1aa9991f8}{206}" paraid="1661520049">In this way, we can fulfill our customers&rsquo; demands for more efficient and more reliable propulsion systems with the best lifecycle costs on the market.</p>
