New propulsion order for a newbuild icebreaker

Steerprop has received a new order for two 2.5 MW SP 60 PULL ARC propulsors to be delivered to a newbuild icebreaking vessel. This strengthens Steerprop’s position as a global supplier of propulsors of this size that can operate in extreme arctic conditions.

As the Arctic summer sea ice continues to melt, arctic routes are experiencing substantial increases in traffic. Although transiting via the arctic waters may cut as much as 50% off the days at sea, it also adds more risk of uncertainty to the route. With the ever increasing number of shipowners investing in vessels capable of navigating through ice, Steerprop’s 2.5 MW PULL ARC propulsors are gaining popularity for vessels that need free-running efficiency and ice-milling capabilities in icy waters.

Experience matters

“We were selected to deliver this special solution to a newbuild icebreaker, thanks to our long-term experience in delivering robust propulsion technology to icebreaking vessels,” says Tapio Aho, Sales Manager at Steerprop.

To date, Steerprop has delivered over 85 ice-class units, most of them now operating in some of the harshest arctic conditions. “This order strengthens our position in the market when it comes to providing demanding icebreaker applications,” he continues. “And we hope that this will open up other new similar opportunities in this niche business sector.”

Rugged throughout

The Steerprop SP 60 PULL ARC propulsion units have been designed and built with multiple layers of redundancies and fail-safes for safe, reliable and efficient operations in the most extreme operating conditions. These advanced propulsors combine ice-breaking power with the reliability of mechanical construction and the accurate controls of modern automation technology.  

This special azimuth propulsor technology provides outstanding performance in all kinds of ice management operations. The ability to direct the vectored thrust from the propeller in a full 360 degrees allows the vessel to widen fairways, blow ice ridges or free arctic installations from the ice.

Remontowa W-series

New-generation Steerprop propulsion units for Polish Remontowa Shipyard being constructed

Two new multipurpose vessels, built by Remontowa Shipbuilding using Steerprop W series propulsion units, are now actively being constructed.

The project got its official start in March 2018, when the contract for construction and delivery was signed between Remontowa Shipbuilding SA and Szczecin Maritime Authority. Then, in June 2018, Steerprop became involved in the project. The company was contracted to supply two propulsion unit ship sets, each including a pair of Steerprop SP 25 WD propulsion units with a control system.

First in many ways

The Steerprop SP 25 W D type of propulsion units are the first in our new ‘workboat series’. The SP 25 W D unit’s lower part housing part is made of cast steel, compared to the previous Steerprop SP 25 D housing of separate bent and welded steel parts. Also, some other SP 25 W D unit structures, such as nozzles, feature improved designs compared to the traditional SP 25 D.

These are the first Steerprop products to receive PRS (Polish Register of Shipping) classification. Furthermore, since the class notation for the vessels will be PRS L1 ice class, this will be a new vessel category for PRS.

Advanced propulsion for excellent performance

Thanks to a flexible diesel-electric propulsion system, the 60-meter-long vessels will feature excellent maneuverability and dynamic positioning performance. In addition, with a deadweight capacity of 350 tons, they can achieve a solid bollard pull of 40 tons at a speed of 15 knots. Additionally, sustainability built into the propulsion system’s design will lower fuel consumption and corresponding emissions.

The delivery of the first propulsion set to Remontowa’s shipyard in Gdansk, Poland, is scheduled for early spring 2019. The second set will be delivered in summer later the same year. Both vessels are expected to be ready for service by June 2020.

Multipurpose all around – year round

The new vessels will be used for key statutory tasks for Poland’s Maritime Authorities in the ports of Szczecin and Gdynia in Poland, replacing two aging buoy tenders – Planeta and Zodiak – in use since 1982.

Their service will mainly include inspection, maintenance, transportation and replacement of navigational buoys. However, the vessels will also be fitted for hydrographic tasks, such as depth measurement, data processing and map amendment. And in case of emergencies at sea, they will be capable of emergency response, including towing operations, oil spill recovery, firefighting and other search-and-rescue tasks.

To further enhance their year-round buoy tender capabilities, both of them will feature high-impact icebreaking power, therefore making them capable of efficient ice management operations in the wintertime. With the advanced design and robust mechanical construction of their propulsion systems, icebreaking endurance will be built-in.

Havyard and Esvagt chooses Steerprop’s LM propulsor

Steerprop has signed a contract to provide the main propulsion for Esvagt’s service operation vessel. The vessel will be built in the Havyard shipyard. Cooperation between Steerprop, Esvagt and Havyard has existed for a long time, and all three companies are highly motivated to develop new, innovative solutions for the maritime industry.

The order consists of three vessels to be equipped with next-generation Steerprop propulsors, SP 20 W D LM, which offer increased modularity, design flexibility, high hydrodynamic efficiency and mechanical robustness. The simplified LM propulsor construction is at the top of its class.

By utilizing the latest technologies, Steerprop LM propulsors will deliver increased overall performance. The propulsors are equipped with an in-built permanent magnet motor to create an integrated unit.

For maximum reliability and service access, Steerprop designed the electric motor inside the vessel hull, instead of outside the hull below the waterline, as is typical. To achieve this, a vertical electric motor with permanent magnet rotor was selected.

Auxiliary systems to the propulsor are not usually taken into account when calculating propulsion efficiency, although their normal operation with constant speed uses a lot of energy. By optimizing the energy consumption of the auxiliary system, total propulsive efficiency can improve by up to 1%.

Senior Sales Manager and Hydrodynamics Specialist Hannu Jukola emphasizes that from the first day Steerprop and its skilled personnel have focused on developing the best propulsors for the maritime market. The company combines the latest technology, carefully selected manufacturing methods, robust construction and best hydrodynamic efficiency on the market.

“We are on the path to define the next generation of propulsors to provide vessels all around the world with the best lifecycle costs, sustainable profit and a small carbon footprint,” he continues.
