Steerprop azimuth propulsion to propel shallow-draught icebreaking walk-to-work vessel

The world’s first double acting, shallow-draught ice-breaking vessel, built by the Dutch shipyard Royal Niestern Sander for the Russian companies Mercury Sakhalin and Pola, will be fitted with Finnish Steerprop’s azimuth units as its main propulsion and steering system.

The walk-to-work vessel will operate all year round in harsh ice conditions, transferring service technicians and equipment to and from offshore platforms from Sakhalin Island in the Russian Far East.

“The vessel is designed to have maximum ice breaking capacity stern first and is capable of breaking one meter of ice”, says Olli Knihti, Sales Manager at Steerprop. “The vessel will be working in shallow waters, which is a restricting factor for the propulsion system. Thanks to our compact design of the propulsion units, we could offer a solution that fits within the draught limitations.”

The contract includes two Steerprop SP 60 PULL ARC propulsors with an input power of 2200 kW each. They are designed for use in arctic conditions and have multiple layers of redundancies. Also included in the order is the Steerprop propulsion control system and Steerprop Care condition monitoring system, which offers the highest possible reliability, based on enhanced predictability, safety and productivity.

Steerprop will deliver the main azimuth propulsion system for a walk-to-work vessel that will start serving offshore platforms on the east coast of Sakhalin Island in December 2021.

“The vessel is almost 76 meters long and 14 meters wide, and as it conforms to Bureau Veritas’ (BV) icebreaker 5 ice class rules, the propulsors’ ice-breaking power will really be put to the test”, Knihti says. “One specialty with our azimuth solution is the ability to direct the slipstream from the propeller in a full 360 degrees. It means that the propeller race can be used to widen fairways, blow ice ridges or for example free arctic offshore installations from ice.”

The vessel will be delivered in December 2021 and Steerprop’s propulsors will be delivered in June 2021.

“The vessel will be operating in challenging ice and weather conditions where reliability and efficient performance are mandatory”, says Knihti. “Steerprop has a two-decade long experience in building extra demanding azimuth propulsors, always tailored to the customer’s needs, and we are very pleased to be cooperating with Royal Niestern Sander in this prestigious project.”

Building a more efficient route in the Finnish archipelago

What enables a ferry to operate more efficiently and sustainably on its route between two islands in the vulnerable Finnish archipelago? It’s about being the best at what you do. Steerprop together with Suomenlahden Telakka have now completed a highly efficient retrofitting project for Finferries’ Prostvik passenger and car ferry.

This project represents a big step forward in energy efficiency.  The old diesel-mechanic system was replaced with electric distribution using Steerprop’s 10 CRP LM propulsion units with an integrated 400 kW permanent magnet motor. The delivery also included a modernized control system and intuitive control panels. Steerprop provided these highly customized units on a short delivery schedule.

“The ferry was originally built in the 80s.  The good and close cooperation with Finferries and Suomenlahden Telakka made this retrofit project possible. It was essential that we could do all checks onboard during the design phase when the ferry was still in operation as well as at the yard during the conversion,” says Olli Knihti, Sales Manager at Steerprop.

Meeting more stringent regulations

Suomenlahden Telakka, the largest small-tonnage vessel repair and maintenance shipyard in Finland, strong advocated the technology to Finferries. “We know Steerprop’s LM configuration saves space in the vessel and brings a greater level of simplicity to the engine room,” says Jukka Jaatinen, Managing Director of Suomenlahden Telakka. “Additionally, it was a more straightforward installation process for us, since the propulsion system is extremely compact with lower weight.”

Now in operation, the electric propulsion system brings greater economic advantages to Finferries. “The diesel engines can run according to the power requirement, and fuel consumption is optimized. The ferry also has a DC link, which allows future upgrades such as adding a battery to the vessel,” states Olli Knihti, Sales Manager at Steerprop.

Steerprop’s solution is ideal for the numerous ferries operating around the world, as regulations become even stricter, not only on a global level but even more so at the local and regional level, such as in the Finnish archipelago.  

“Steerprop is committed to the principle of where meeting customers’ needs is at the core. And only the best will do. This ferry retrofit is good proof that our solutions and way of thinking create great results for our customer and also for the environment,” Knihti continues.

Innovative contra-rotating propeller (CRP)

The Steerprop 10 CRP LM propulsor system offers excellent efficiency. The dual-end CRP combines the exceptional maneuverability of azimuth propulsors with low pressure pulses and noise levels. The integrated vertical permanent magnet motor provides reliable high-power propulsion, increased fuel savings and lower emissions. Steerprop has delivered over 140 CRP units to vessels throughout the world.

Focusing on innovations that challenge the industry

Our company goal and long-term vision is to bring to the market superior propulsion units with outstanding efficiency, exceptional reliability and the lowest lifecycle costs on the market. This strong product vision has always guided the brilliant minds of the Steerprop R&D department.

As we’re concentrating on creating more efficient propulsors, we plan to lower mechanical losses and improve propulsion efficiency with high-quality propeller designs and by optimizing the shapes of underwater parts. Our gear design specialists, technical analysts and hydrodynamists are working hard toward this end. As we create more efficient propulsion units, we are creating more environmentally friendly solutions, while also providing better returns through lower fuel consumption.

The reliability of our propulsors is essential. They are used in critical operations, such as ice management, on icebreakers, oil platforms, wind farm maintenance vessels and cruise vessels, where any interruption can cause huge losses. Our technical department makes lots of calculations, taking into account challenging conditions in both open and icy waters. For example, our gear designers look at different kinds of load cases so that the propulsor tooth contact patterns are ideal for every condition and situation.

To ensure the best lifecycle costs, we have developed Steerprop Care, our online monitoring service, which enables us to support operational quality. Steerprop Care allows us to turn unplanned disturbances into planned service. For example, we can save customers time and money by monitoring the life of the propulsor unit’s power transmission line. This gives customers the assistance they need to avoid unnecessary downtime and maintenance, which negatively affects lifecycle costs.

Creating a powerful and engaging product vision

To achieve our goals, we are always open to new ideas and developments. This requires close cooperation with our component suppliers and manufacturers, listening to their research projects and continuously learning more.

The maritime industry also presents new challenges. When customers ask us for larger propulsors, this creates more complexities when it comes to material properties and manufacturability. By working in close cooperation with the world’s leading component manufacturers, we can meet these industry challenges. For example, we work in close cooperation with companies that specialize in gears 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.

We’ve developed the CRP ECO product line to focus primarily on improving efficiency. The whole propulsor is pressure lubricated to lower mechanical losses compared with the commonly used oil bath lubrication technology. To ensure reliability, our comprehensive factory tests verify system functionality.

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.

Another big development area 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 can also avoid upper gear excitations in the ship hull, which is especially important for cruise vessels. Currently, we are working in close cooperation with our partners to make LM units possible also for larger units.

Teamwork all the way

Creating and executing a strong product vision is not a one-person process or project. Numerous internal and external factors are guiding this process. To succeed, it is important to be surrounded by visionaries and brilliant individuals.

Steerprop’s R&D department has highly motivated in-house experts from many different fields – along with external specialists – working closely together to produce outstanding propulsors. They do their best every day – bringing skills from mechanical design and analyzing, hydraulics, hydrodynamics, materials, and sealing systems to create superior products for our customers.

In this way, we can fulfill our customers’ demands for more efficient and more reliable propulsion systems with the best lifecycle costs on the market.
