<p class="article__lead-paragraph">What if your vessel has mechanically many years to go, but electrical systems are badly outdated? This was a problem tug operator Alfons Hakans was facing until Steerprop&rsquo;s Lifecycle Extension Services were offered to the tug called Dunker. Modernizing and consequently ensuring the reliability of the control system will add at least 15 years of operations to the tug, according to Alfons Hakans&rsquo; assessment.</p>

<p class="article__paragraph">When Alfons Hakans recently bought the vessel Dunker, they gave it a full health check. The vessel&rsquo;s hull as well as the old propulsion units were all mechanically in very good condition. However, the electrical parts of the vessel, especially the propulsion control system, from control levers to the propulsion internal control system, had seen better days. Operating the ship with unreliable and outdated technology would be challenging and needed immediate attention.</p>

<p class="article__paragraph">&ldquo;We have worked with Steerprop previously on a similar project, <a href="https://steerprop.com/stories/retrofit-artemis">Artemis</a>, and we were very happy with the success of that project. It was natural to approach them regarding modernizing the Dunker as well,&rdquo; says Tuomas Raumanen, Technical Manager at Alfons Hakans.</p>

<blockquote>
<p class="article__paragraph">&ldquo;Additionally, Steerprop was able to offer several custom-made engineering solutions to fulfill our quite specific operational needs,&rdquo; Raumanen adds.</p>
</blockquote>

<p class="article__paragraph">To resolve Alfons Hakans&rsquo; challenges with out-of-date propulsion control system technology on the Dunker, Steerprop held thorough discussions with the captains and technical personnel of the vessel, gathering direct feedback and requests for various technical features to the updated solution. Close cooperation with the customer enabled Steerprop to engineer a retrofit installation based on a customized scope of Lifecycle Extension Services, which will considerably ease the vessel&rsquo;s operations in the future.</p>

<p class="article__paragraph">The delivery will include a state-of-the-art control system for the existing propulsion units, the main propulsion bridge equipment, and a renewed service relationship. The retrofit project is scheduled to take place in autumn 2023.</p>

<p class="article__paragraph">Steerprop&rsquo;s high-quality control system offers a first-class maneuvering experience and high operational reliability, as well as control levers that are equipped with full redundancy, enabling complete follow-up backup control. The system also allows for remote service support via the Steerprop remote service module.</p>

<blockquote>
<p class="article__paragraph">&ldquo;We are extremely pleased that Alfons Hakans has chosen to strengthen our already excellent cooperation and decided to develop their fleet with us. Nurturing close customer relationships and resolving challenges for, and together with, our customers has always been at the core of our business,&rdquo; says Esa Peltomaa, Technical Sales Manager at Steerprop.</p>
</blockquote>


Modernizing and consequently ensuring the reliability of the control system will add at least 15 years of operations to the Alfons Hakans’ tug Dunker, which will be updated with Steerprop’s Lifecycle Extension Services’ retrofit in autumn 2023.

<p class="article__lead-paragraph">Every year we at Steerprop look for summer trainees with a resolve to perform &ndash; students that are curious and solution-focused and who are eager to learn and develop both on a personal and professional level. We have talked to Vilma and Olavi who started working at Steerprop as summer trainees and have now continued to work with us alongside their studies.</p>

<p class="article__paragraph">Vilma Heinonen from Tampere is in her fourth year of Information and Knowledge Management studies, and Olavi R&auml;is&auml;nen from Oulu is a Mechanical Engineering Master&rsquo;s degree student.</p>

<p class="article__paragraph">When Olavi started to look for a summer job, he had a couple of criteria: &quot;I wanted to work with mechanical engineering design and I hoped to find a company where I could also work on and complete my Master&rsquo;s thesis,&quot; Olavi says.</p>

<p class="article__paragraph">At Steerprop he found the summer job that met his criteria. During the summer Olavi worked at the Product Management department with his own design project, and since then he has continued the work he started in the summer as part of his Master&rsquo;s thesis: &quot;At the end of the summer I was offered a thesis topic related to the preloading of propeller shaft bearings. Since my experience from the summer was nothing but positive, I was happy to continue at Steerprop. The topic is really interesting and the work has progressed well so far,&quot; Olavi says.</p>

<figure class="article__figure">
<div class="article__figure__placeholder"><img alt="After the summer, Olavi continued working on his Master's thesis at Steerpop." src="https://flockler.com/thumbs/sites/13425/olavi_2-2cd5a82f-9057-4ec0-9a01-613158b554a5_s600x0_q80_noupscale.jpg" /></div>

<figcaption><span class="article__figure__caption">After the summer, Olavi continued working on his Master&#39;s thesis at Steerpop.</span></figcaption>
</figure>

<p class="article__paragraph">Vilma, on the other hand, worked in the Project Management department with tasks mostly linked to production planning. She was able to experience how her work had concrete impact on the company as she got to be part of refining the operations of Steerprop&rsquo;s new production and assembly workshop. This work gave her an excellent overview of the entire company&#39;s operations: &quot;If I had to pinpoint one specific thing that I learned over the summer, it would probably be the configuration of the azimuth propellers. I spent so many hours during the summer working on production processes and instructions that I could probably account for the whole production process in my sleep,&quot;&nbsp;she says.</p>

<p class="article__paragraph">As all summer trainees, Olavi and Vilma have been given many opportunities to learn and develop new skills and to apply their studies in practice. &quot;I have learned a lot of useful things at the university, such as project management, quality management and mechanics,&quot; Vilma says. &quot;However, I consider the ability to apply one&#39;s own knowledge and the courage to try new things to be even more important,&quot; she continues.</p>

<p class="article__paragraph">&quot;I have earlier worked in maintenance planning, but since then I decided to change the direction of my studies. I want to be able to influence the usability, durability and maintainability of machines already at the design table, and that&rsquo;s why I switched my major to machine design,&quot; Olavi tells us.</p>

<blockquote>
<p class="article__paragraph">&quot;All the work I did at Steerprop during the summer has been strongly related to my current studies. Using what I have learned at university in practice has strengthened and deepened my skills,&quot; he adds.</p>
</blockquote>

<p class="article__paragraph">Both Vilma and Olavi agree that their expectations for the summer were met at Steerprop.</p>

<p class="article__paragraph">&quot;I really enjoyed my summer job, it was suitably challenging and it included a fair amount of independent problem solving. The Steerprop work community is really nice and I&rsquo;m happy for the opportunity to stay and continue with my thesis work,&quot; Olavi says.</p>

<figure class="article__figure">
<div class="article__figure__placeholder"><img alt="The skills learned during the summer at Steerprop have been useful to Vilma in her studies." src="https://flockler.com/thumbs/sites/13425/vilma_2b-49eb84bd-743e-4026-9b3d-fcc73473f170_s600x0_q80_noupscale.jpg" /></div>

<figcaption><span class="article__figure__caption">The skills learned during the summer at Steerprop have been useful to Vilma in her studies.</span></figcaption>
</figure>

<p class="article__paragraph">&quot;I think it&rsquo;s the people that make a workplace great. The good feeling I got already when interviewing for the job at Steerprop encouraged me to move to Rauma for the summer. I knew that I would have nice colleagues and an interesting summer,&quot; Vilma says.</p>

<blockquote>
<p class="article__paragraph">&quot;My expectations&nbsp;were definitively met and I spent a fun and educational summer in Rauma!&quot;</p>
</blockquote>

<p class="article__paragraph">After the summer, also Vilma continued to work at Steerprop alongside her studies. She has now been working with e.g. production planning and competitor analyses. &quot;Combining studies and work has gone without any major challenges as I can decide on my working hours quite freely,&quot; Vilma says. &quot;I am currently studying product and process information management, i.e. production system planning, production control and production technology, for example. These areas are quite familiar to me from my summer job at Steerprop and it has proven very helpful in my studies,&quot; she continues.</p>

<p class="article__paragraph">Looking back at her first days at Steerprop in the summer, Vilma remembers one particular moment that made her studies that much more concrete: &quot;I will always remember my first visit to the production hall at Steerprop. For someone who dreamed of becoming a dolphin trainer as a little girl, seeing that first propeller with my own eyes made it real to me; I really am going to be an engineer,&quot; she says with a smile.</p>

Every year we at Steerprop look for summer trainees with a resolve to perform – students that are curious and solution-focused and who are eager to learn and develop both on a personal and professional level.

Working at Steerprop supports students' development as professionals

<p class="article__lead-paragraph">Every third icebreaker in operation around the world features Steerprop propulsion units. While icebreakers frequently operate in the world&rsquo;s most vulnerable ecosystems, one needs top level quality and unrelenting attention to detail. Steerprop delivered its first propulsion units for an icebreaker in 2008 and has been a true player in this demanding arena ever since &ndash; having delivered, for example, the largest mechanical azimuth propulsors in the world.</p>

<p class="article__paragraph"><strong>Hannu Jukola</strong>, Senior Sales Manager at Steerprop, is an industry expert with over 30 years of experience from the sector. As a Naval Architect who specialized in hydrodynamics, Jukola knows the number one thing that customers look for in an ice-proof propulsion solution:</p>

<blockquote>
<p class="article__paragraph">&ldquo;In demanding conditions, reliability is always the most important thing. Our R&amp;D has always taken this kind of ultimate dependability to be the foundation of everything we do: the propulsion must be able to perform, day in and day out.&rdquo;&nbsp;</p>
</blockquote>

<p class="article__paragraph">To date, the propulsion units aboard Steerprop&#39;s first icebreaker deliveries have continuously operated for over 100,000 hours without any major overhauls, for example, to change the bearings. This achievement is truly remarkable and speaks volumes of the skill and commitment of the company&#39;s&nbsp;R&amp;D.</p>

<h2 class="article__heading--h2">Resolve to perform</h2>

<p class="article__paragraph">Icebreakers are needed, since year-round marine transportation is not given on the Northern hemisphere. To make sure that that the marine transport is unhindered by local ice conditions, many countries operate icebreaker fleets. The main task of the icebreakers: to secure an efficient, predictable marine transportation system in and out of the ports, even in the dead of winter.</p>

<figure class="article__figure">
<div class="article__figure__placeholder"><img alt="Icebreakers are needed to ensure marine transport in all ice conditions." src="https://flockler.com/thumbs/sites/13425/sp_vessel_in_ice_1_small-7e49e1aa-dc92-4050-9060-fe8aa761bcf7_s600x0_q80_noupscale.jpg" /></div>
</figure>

<p class="article__paragraph">Steerprop feels very strongly about sending only the best, most robust technology into the Arctic. When you need to go to these fragile areas, it&rsquo;s wise to use vessels with the best solutions &ndash; like Steerprop&rsquo;s.</p>

<p class="article__paragraph">&ldquo;One can not take any chances with the delicate Arctic nature and all vessels passing through the area must safeguard against any sort of technical mishap,&rdquo; Jukola says. Similarly, extreme caution must be taken in the North Sea and the Baltic Sea, as well.</p>

<h2 class="article__heading--h2">New techniques emerging</h2>

<p class="article__paragraph">Typically, ice conditions upon the seas vary from year to year and place challenges to operations. Therefore, because ship sizes are becoming larger, also new icebreaking techniques have evolved.</p>

<p class="article__paragraph">&ldquo;In a traditional icebreaker, operating bow first propulsors with pushing propellers give the needed push to break ice. The use of azimuth propulsion units with pulling type propellers opens new operation possibilities; the icebreaker can go stern first into ice and the propellers can &lsquo;eat&rsquo; their way through the ice,&rdquo; says Jukola.</p>

<blockquote>
<p class="article__paragraph">&ldquo;Also the propeller wash can be used to clear ice ridges or widen the channel so that the assisted vessel can follow the icebreaker more easily,&rdquo; he adds.</p>
</blockquote>

<h2 class="article__heading--h2">Balancing act</h2>

<p class="article__paragraph">Managing a vessel through thick ice can be a daunting task even under the best of circumstances: for instance, lack of propulsion power can easily cause a ship to become stuck. Due to ice class requirements, shipowners are forced to balance between bollard pull/icebreaking thrust and free running efficiency.</p>

<figure class="article__figure">
<div class="article__figure__placeholder"><img alt="Managing a vessel through thick ice can be a daunting task. Therefore the propulsion solution needs to be both efficient and reliable." src="https://flockler.com/thumbs/sites/13425/sp_vessel_in_ice_3_small-9bac89f9-a33b-49cb-9f79-c48e7f3d9e84_s600x0_q80_noupscale.jpg" /></div>
</figure>

<p class="article__paragraph">Hannu Jukola says that the harsh conditions of ice-covered waters demand reliable propulsors that can provide vessels with that extra thrust in a tight spot. Steerprop utilizes contra-rotating propellers (CRP) in a push-pull configuration to take icebreaking capability, manoeuvrability and performance to the next level.</p>

<p class="article__paragraph">&ldquo;Steerprop&rsquo;s Arctic azimuth propulsors with contra-rotating propellers offer higher free running efficiency &ndash; as well as higher thrust in bollard and icebreaking conditions&rdquo;, says Jukola. Steerprop CRP units consume about 15% less fuel than traditional solutions.</p>

<h2 class="article__heading--h2">Fit for purpose</h2>

<p class="article__paragraph">From a design perspective, however, CRP is not the only choice out there. Depending on the work role / scope and operational profile of the vessel in question, Steerprop can accommodate all kinds of vessels with the right solution. Throughout this process, people are the key &ndash; customizing solutions to be the perfect match for the project in hand requires keen collaboration.</p>

<p class="article__paragraph">Steerprop&rsquo;s entire &lsquo;fit for purpose&rsquo; ideology starts and ends with understanding the needs of the customer &ndash; and, therefore, every delivery is a result of committed customer cooperation. Hannu Jukola says that Steerprop&rsquo;s solutions resolve its customers&rsquo; challenges in such a way that they add &ldquo;critical value&rdquo; to their business operations.</p>

<blockquote>
<p class="article__paragraph">&ldquo;The very best result is achieved when we can support and advise our customers as early as possible, preferably in the ship design phase,&rdquo; says Jukola.</p>
</blockquote>

<p class="article__paragraph">&ldquo;Our support services range from the initial needs analysis and proposing the best maintenance solution to providing service throughout the lifecycle of the solution,&rdquo; he adds.</p>

<p class="article__paragraph">Steerprop has delivered more than 90 units for ice-classed vessels, including icebreakers. In fact, the world&rsquo;s most powerful and highest ice-class mechanical azimuth propulsors are included on that list.</p>

<figure class="article__figure">
<div class="article__figure__placeholder"><img alt="Steerprop Care condition monitoring enables you to focus in predictive maintenance." src="https://flockler.com/thumbs/sites/13425/sp_care_9_small-18cc9f7a-fb74-4638-a8f3-25172b384317_s600x0_q80_noupscale.jpg" /></div>
</figure>

<h2 class="article__heading--h2">Condition monitoring edge</h2>

<p class="article__paragraph">In recent years, Steerprop has made considerable advances in predictive and preventive maintenance. Focused around a data-driven maintenance strategy, Steerprop&rsquo;s service technicians have adopted a condition-based approach to maintenance. The basic condition monitoring (Steerprop Care Standalone) is delivered as a standard feature in every Steerprop propulsion delivery.</p>

<blockquote>
<p class="article__paragraph">&ldquo;This means you can focus on preventive maintenance, instead of merely performing reactive and corrective measures when it&rsquo;s already too late,&rdquo; Jukola explains.</p>
</blockquote>

<p class="article__paragraph">Thanks to this advanced condition monitoring, shipowners are able to increase the reliability and safety of their vessels, while reducing costs and downtime caused by unexpected maintenance needs. As there&rsquo;s no unnecessary, frequent docking, operations run a lot more smoothly.</p>

<p class="article__lead-paragraph">Every summer we at Steerprop offer a variety of interesting and versatile trainee positions in several departments at our headquarters in Rauma. In this way we help secure future availability of knowledgeable expertise in our industry. Our summer trainees receive valuable work experience and an opportunity to apply the competences they acquire during their studies in practice, and we get to enjoy these future professionals&rsquo; enthusiasm, energy and fresh, new ideas.</p>

<p class="article__paragraph">The summer is now over, and we have said goodbye to our summer trainees as they have returned to their studies. But before they left, we asked some of them to tell us a little about their summer with us.</p>

<p class="article__paragraph"><strong>Oskari Ojamaa</strong> and <strong>Markus Taulu</strong> are both Master&rsquo;s degree students of Information and Communication Technology. Oskari is studying at the University of Turku and is starting his third year of studies, while Markus is starting his fourth year at the LUT University in Lappeenranta.</p>

<p class="article__paragraph">Oskari is already quite familiar with Steerprop, this summer was already his fourth in Steerprop&rsquo;s Product Management department, and he has had the opportunity to work with many different tasks together with highly skilled and experienced colleagues.</p>

<p class="article__paragraph">&quot;Working at Steerprop during these four summers has felt special to me. I have encountered many different tasks and challenges, from printing and assembling customer manuals during my first summer, to web programming and reviewing integral calculus this past summer,&quot; he says.</p>

<blockquote>
<p class="article__paragraph">&quot;The tasks have developed nicely along the development of my own skills,&quot; he continues. &quot;This is one of the reasons why I have been happy to return to Steerprop one summer after the other.&quot;</p>

<p class="article__lead-paragraph">Shipowners and operators are fully aware that minimizing operational risks at sea and maintaining reliability is vital for maintaining profitability. The lifecycle of a ship easily extends beyond 25 years. During this time, for example, the control system for the vessel&#39;s main or auxiliary propulsion system can become obsolete, while the propulsion system itself still has years of operational capability. &quot;The control system is vital for a vessel&#39;s reliability and safety. And we are able to effectively help shipowners extend the lifetime of their vessels via a control system retrofit, regardless of whether or not we are the original manufacturer&quot;, says Esa Peltomaa, Technical Sales Manager at Steerprop Ltd.</p>

<p class="article__paragraph">As a control system becomes older it becomes much more difficult to replace obsolete parts or find qualified technical support or service engineers. In a worst-case scenario, the original manufacturer has either disappeared from the market altogether or stopped their support for the solution in question. In such a situation, shipowners are left on their own to face overwhelming challenges in terms of keeping their business going with sufficient reliability.</p>

<p class="article__paragraph">&quot;If a shipowner ends up in such a situation, there might be very few options left open in terms of restoring reliable operation to the vessel, and even fewer possibilities that make any sense to pursue, no matter from which business angle you look at it&quot;, explains Mr. Peltomaa.</p>

<h2 class="article__heading--h2">Extending your vessel&#39;s lifetime</h2>

<p class="article__paragraph">Sometimes an original manufacturer may need to replace the entire propulsion system, including the propulsion units, even though mechanically such units would have many years of operational capability remaining. Steerprop can help shipowners when a control system retrofit is economically feasible and it is possible to find a suitable delivery and installation time. Moreover, even when the parts you need are no longer manufactured, and any assistance from the original manufacturer is unavailable, you can still turn to Steerprop.</p>

<p class="article__paragraph">The Steerprop Control System features superior quality, reliability, redundancy, serviceability, user-friendliness, and flexibility.</p>

<blockquote>
<p class="article__paragraph">&quot;We have the retrofit solutions and the expertise to help shipowners extend the lifetime of their vessels effectively, even if the current propulsion system is not manufactured by us&quot;, says Mr. Peltomaa.</p>

<h2 class="article__heading--h2">Built-in redundancy</h2>

<p class="article__paragraph">At Steerprop, we take great pride in creating propulsion solutions and systems that have full redundancy, further enhancing the vessel&#39;s reliability and safety.</p>

<p class="article__paragraph">The Steerprop Control System retrofit is the best option for shipowners wanting superior operational reliability and high quality. This is ensured by control levers with full redundancy, enabling a complete follow-up backup control from the control levers at the bridge to the propulsion unit.</p>

<p class="article__paragraph">All control levers have dual maintenance-free sensors to eliminate unnecessary servicing. &quot;The redundancy is guaranteed by an independent backup control system, which makes it possible to always restore a vessel to a safe state even after a suspected fault. The backup system is also continuously monitored and protected by the main system, ensuring continuous availability&rdquo;, says Mr. Peltomaa.</p>

<h2 class="article__heading--h2">Proven quality systems shorten a vessel&rsquo;s downtime</h2>

<p class="article__paragraph">At Steerprop, we follow all the relevant industry standards and best practices, and our technical solutions are certified by maritime classification societies. We are certified according to ISO 9001, ISO 14001 and ISO 45001 standards. But what does that mean in practice?</p>

<p class="article__paragraph">The entire control system, including controllers, cabinets and control panels, is tested together as a complete package. The testing is part of Steerprop&#39;s rigorous quality assurance. &quot;This means that the control panels, touch screens and electrical cabinets are connected and tested with the actual software you use. This ensures compatibility and functionality before the installation, thus smoothing and speeding up the commissioning to guarantee the shortest possible downtime for a vessel&quot;, says Mr. Peltomaa.</p>

<p class="article__lead-paragraph">Are you planning a new ferry build? If the answer is yes, then you would probably want to optimise your costs by focusing on the Total Cost of Ownership (TCO) instead of kW-power. Choosing the propulsion unit based mainly on Capex, for example, will most likely increase costs in the long run. In this article we present a case study, showing that a ferry owner can save more than two million euros over a 15-year period by concentrating on the TCO.</p>

<p>The traditional way of handling the procurement of propulsion systems, among other things, is to request quotations for propulsion units based on one specific value, typically kW-power. The one with the lowest price often wins the bid, contributing to lowering the newbuilding unit cost.</p>

<p>However, we need to consider that the cost of a newly built ferry makes up only a fraction of the TCO. A ferry, as well as any other vessel, is designed to be in service for many years. Therefore, it is important to consider the vessel&rsquo;s purpose and planned operation when choosing the propulsion solution.</p>

<p>Comparing different propulsion system suppliers can be a complicated process when a holistic picture of a ferry&rsquo;s lifecycle costs is unavailable. For a ferry doing daily repetitive crossings the TCO is what matters the most. The total cost of ownership includes the newbuilding unit cost, maintenance and spare part costs as well as operational energy costs. The current procurement process focusses only on the newbuilding unit cost, even though the energy costs are by far the dominating factor when we talk about TCO.</p>

<h2 class="article__heading--h2">Simulation-based ferry propulsion design for a 120 CEU double-ended ferry</h2>

<p>At Steerprop we decided to examine the TCO impact by doing a simulated case study of some very likely operating scenarios.</p>

<p>We wanted to find out the best ways to design a ferry propulsion system. The example used in the study was a 120 CEU (Car Equivalent Unit) double-ended ferry that would run on four ferry routes of different lengths and crossing times.</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/sp_figure1-0ce28479-8e82-49f8-933c-7e57b95cd803_s1800x0_q80_noupscale.jpg" target="_blank"><img alt="Main characteristics of the ferry type used in the simulation." src="https://flockler.com/thumbs/sites/13425/sp_figure1-0ce28479-8e82-49f8-933c-7e57b95cd803_s600x0_q80_noupscale.jpg" /></a></div>

<figcaption><span class="article__figure__caption">Figure 1: Case study - Main characteristics of the ferry type used in the simulation.</span></figcaption>
</figure>

<h2 class="article__heading--h2">Selecting the variables</h2>

<p>In addition to the given vessel characteristics, several other variables also need to be decided. These cover project information, propulsor variables and operational variables for the crossing. Among others, these parameters were used:</p>

<ul>
	<li><strong>Project information.</strong> This area covered features such as route length, target crossing time, bollard pull requirement (optional), which are details usually defined by the owner. Ship specific data is then provided by the ship designer, including displacement, resistance curve, thrust deduction and wake fraction.</li>
	<li><strong>Propulsor variables.</strong> The following parameters were used for the propulsor: propeller diameter, RPM and pitch design point, and propulsion max power. Secondary variables were auxiliary systems power and lubrication oil temperature.</li>
	<li><strong>Crossing operational variables.</strong> When simulating the crossing, these variables were used: manoeuvring time and length at both ends, acceleration time and power, crossing speed (knots), deceleration time, including angle and power of the propulsors. Moreover, the power was split between front and aft units in all modes.</li>
</ul>

<p>Steerprop was looking for the total energy used for the different crossings (kWh) in the study. This was complemented by combining a specific cost model where attention was given to the energy cost for the crossing (&euro;) and the cost of the propulsion unit (including initial and maintenance costs). For the total cost of ownership, a 15-year period was selected. We also added the possibility to compare different propulsion configurations.</p>

<h2 class="article__heading--h2">Designing the optimal propulsion unit</h2>

<p>How to design the optimal propulsion unit? The answer lies in the balance between Capex (Capital Expenditures) and Opex (Operating Expenses) on the one hand, and the relation between power and torque on the other. For example, a propulsion unit that has better acceleration capabilities or a free running efficiency might cost slightly more but reduces energy consumption significantly. The challenge is to find the best optimal balance. With low power, we gain low Opex, whereas with low torque, we gain low Capex.</p>

<p>It is possible to find the optimal combination of Capex and Opex through studies using both route simulation and cost models.</p>

<h2 class="article__heading--h2">Operational analysis forms the basis for an optimal TCO</h2>

<p>The actual simulation was performed using four ferry routes and three CRP (contra-rotating propellers) propulsion options. The ferry routes, including distances and crossing times used, are shown in Table 1.</p>

<figcaption><span class="article__figure__caption">Table 2: Studied CRP propulsion options.</span></figcaption>
</figure>

<p>Table 2 above shows that options one and two use a reduced RPM for the propeller and increased torque and an enlarged propeller diameter, among other things. These two options also have a higher Capex, but the results show that there are also substantial annual savings that improve the total cost of ownership.</p>

<p>The results outlined in Figure 2 clearly show that from a TCO perspective, it pays to design propulsion units according to the vessel&rsquo;s operational profile.</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/sp_figure2-f145d6d7-49a7-4134-9479-9ad6c4e19230_s1800x0_q80_noupscale.jpg" target="_blank"><img alt="Results from the simulation with different CRP options" src="https://flockler.com/thumbs/sites/13425/sp_figure2-f145d6d7-49a7-4134-9479-9ad6c4e19230_s600x0_q80_noupscale.jpg" /></a></div>

<figcaption><span class="article__figure__caption">Figure 2: Results from the simulation with different CRP options on four different ferry routes.</span></figcaption>
</figure>

<p>Option two consumes 13% less energy than the &ldquo;baseline&rdquo; option on the 14 minute-crossing. We can also see clear annual savings for both options on all ferry routes, which vouches for short payback times, especially on the shorter crossings.</p>

<p>The second option, which focuses on optimising the acceleration phases, benefits ferries operating short crossings where accelerations occur frequently. The total cost of ownership in the 4 km crossing example is slightly over 17,000,000 euros. If we look at annual savings exceeding 160,000 euros, we can see that over a 15-year period, the total savings are more than 2.4 million euros.</p>

<p>The simulation results show that operational analysis is the foundation for finding an optimal total cost of ownership. In addition, significant energy savings can be achieved by involving propulsor design as part of the ship design process.</p>

<p>Reliable year-round marine transportation systems are crucial in modern societies, such as the countries along the<br />
Baltic Sea. To ensure that marine transportation systems are impacted as little as possible by the ice conditions around the coasts, the countries operate large fleets of icebreakers. The main task for icebreakers in the Baltic Sea is to secure an efficient and predictable marine transportation system in and out of harbors along the coasts.</p>

<p class="article__lead-paragraph">Shipping company Alfons Hakans trusted Steerprop to modernise the control system on Artemis, one of the longest serving ASD tugs in the company&rsquo;s fleet. Steerprop made the process quick, easy, and cost-efficient.</p>

<p>Back in 2019, the technical department at Alfons Hakans noticed a need to modernise and upgrade the propulsion control system on its Azimuth Stern Drive tug <em>Artemis</em>. It was no longer possible to get spare parts to its original control system; and although it was still reliable, for safety reasons the company decided to look for reasonable solutions for a full-scale upgrade.</p>

<p>&ldquo;We noticed pretty quickly that it made sense to renew all parts related to the control of the propulsion units,&rdquo; says technical manager <strong>Tuomas Raumanen</strong>. &ldquo;Basically, everything between the master&rsquo;s hands and propulsion units had to be replaced, including things like control levers, cables, computer units, and feedback sensors.&rdquo;</p>

<p>Alfons Hakans began to look for suppliers, and Steerprop, located near Hakans headquarters, promptly gave a quotation. Raumanen notes that Hakans particularly appreciated the ease of communication and rapid responses, and this, topped with fast delivery and a reasonable price, made Steerprop an obvious choice.</p>

<h2 class="article__heading--h2">Minimal downtime</h2>

<p>The final order was confirmed at the end of 2020. First, Steerprop paid a few visits to get to know Artemis and its operations. During these visits, a timetable was set to ensure the downtime of the tug was kept to a minimum.</p>

<p>To decrease the amount of downtime, Hakans&rsquo; own workers and subcontractors started preliminary works, such as installing new cables and manufacturing foundations for electric cabinets, whilst the tug was still operating normally. Meanwhile, Steerprop was building the entire control system at their workshop.</p>

<blockquote>
<p>&ldquo;This way the installation time on board would be as short as possible,&rdquo; Raumanen says.</p>
</blockquote>

<p>The installation began at the end of August. First, the old control system was dismantled, and the team ensured that all necessary cables had been installed. Next, all electric cabinets related to the new system were installed, which was an easy process thanks to all the preliminary work.</p>

<p>Connecting the new cables to different units was the most time-consuming part, and it was completed on schedule. After seven days of work, it was time to run a test. During the sea trials, the adjusting of the final parameters was easily done as it had been considered already when planning the software.</p>

<h2 class="article__heading--h2">Increased reliability</h2>

<p>From the beginning of the installation to final approval from Alfons Hakans, installing the new control system took nine days in total.</p>

<p>&ldquo;After sea trials and final adjustments our masters and chief engineers were satisfied and also surprised how well whole process went,&rdquo; Raumanen says. &ldquo;Of course it takes a while before masters and others get used to a new type of control levers, but that&rsquo;s common when changes are made to older vessels.&rdquo;</p>

<p>The biggest advantages in comparison to the old system are, in Raumanen&rsquo;s view, that all adjustments are very easy to make and the new system is significantly more reliable. The information the system provides about the status of the propulsion units is also much easier to understand.</p>

<p>In total, Raumanen estimates the upgrade to add 10 to 15 years to the lifecycle of the vessel.</p>

<blockquote>
<p>&ldquo;All in all, we&rsquo;ve been satisfied with the new control system and will continue our good relationship with Steerprop in the future,&rdquo; he notes.</p>

<h2 class="article__heading--h2">Remote service diagnostics streamline maintenance</h2>

<p>From Steerprop&rsquo;s point of view, the co-operation between Alfons Hakans went extremely well. Technical Sales Manager <strong>Esa Peltomaa</strong> tells that Steerprop designers were in frequent contact with the personnel on board to ensure that the new system fitted existing spaces and locations as well as fulfilled the wishes of end users.</p>

<p>Steerprop delivered a control system modified to existing propulsion, as well as a bridge control system with control levers, control panels and relevant touch screens. Like Raumanen, Peltomaa says that the new system is more user-friendly than the old one, and it also conveys detailed information that makes service operations, changing settings, and calibrations easy and reliable.</p>

<p>Steerprop was also able to make customisations based on the customer&rsquo;s wishes. For example, bridge control panels were customised to fit existing cabinets, and touch screen views, control panel buttons, and indications fit existing vessel functionalities and wanted functions.</p>

<blockquote>
<p>&ldquo;By modernising the system, Steerprop also provided a capability for remote service diagnostics, which gives Steerprop&rsquo;s service department the ability to diagnose faults and status of the system remotely,&rdquo; Peltomaa explains.</p>
</blockquote>

<p>&ldquo;This makes better service assistance possible by diagnosing possible faults even before the first service engineer&rsquo;s visit on board.&rdquo;</p>

<p>Essentially, the vessel has now been future-proofed. For example, should Alfons Hakans want to replace existing units with Steerprop&rsquo;s azimuth propulsors, the existing control systems can be fully utilised with minimal changes to further improve cost effectiveness.</p>

<p>&ldquo;Steerprop guarantees the serviceability for our products for decades by using and selecting components that are not becoming obsolete as well as designing the system well enough that future upgrades are possible with minimal work,&rdquo; Peltomaa concludes.</p>

<p paraeid="{2762ac1f-02ff-4c77-b509-7f9e771c795d}{47}" paraid="121277023">We provide our customers with superior propulsion units with outstanding efficiency, exceptional reliability and the lowest lifecycle costs on the market. Our gear design specialists, technical analysts and hydrodynamists are all working hard toward this end.</p>

<p paraeid="{2762ac1f-02ff-4c77-b509-7f9e771c795d}{73}" paraid="713311675">With our high-quality propeller designs we improve propulsion efficiency, we also constantly work on lowering mechanical losses and optimizing the shapes of underwater parts. The equation is easy - more efficient propulsion units means lower fuel consumption and better returns for our customers!</p>
</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>
