The order was placed in May by Singapore-based Sembcorp Marine Ltd, which has secured a contract for the construction of the vessel for Maersk Supply Service of Denmark. Steerprop experienced specialists have worked in close cooperation with Sembcorp Marine throughout the design process.

“At Steerprop, we are committed to working closely with our customers during the design stages of each project. This collaboration enables the optimal solution for the specific application and operational conditions to be created,” said Olli Knihti, sales manager at Steerprop. “This project emphasizes our capabilities to deliver a broad package of high-quality solutions that meet the latest design requirements and operational needs. We are also able to support customers throughout the lifecycle of the vessel with our Resolve to Perform approach.”

The company’s scope includes six of Steerprop’s ducted L-drive azimuth propulsors with an output power of 4500 kW and two 900 kW Steerprop tunnel thrusters for dynamic positioning, maneuvering, and transit operations. To support safe and reliable operations with low lifecycle costs, Steerprop Care condition monitoring is also included as part of the package.

The jack-up type WIV incorporates a first-of-its-kind design with a load transfer system patented by Maersk Supply Service. The design also takes into consideration the need to operate safely and efficiently in the harsh sea conditions the vessel is likely to face while serving the Empire Offshore Wind project off the eastern coast of the USA. This set up high requirements for the propulsion effectiveness and reliability, which Steerprop was able to demonstrate.

“In collaboration with Maersk Supply Service, Sembcorp Marine will design and build a WIV capable of operating at a high level of efficiency and to handle the next generation of wind turbines which are scaled up in size with longer and lighter rotor blades and taller towers,” said Wong Teck Cheong, senior vice president at Sembcorp Marine Rigs & Floaters. “The vessel is designed to cope with the installation of bigger structures and to ensure operational efficiency for wind turbine installations. The Steerprop thrusters will play an essential role in enabling this efficiency.”
