Wärtsilä providing thrusters for new Boskalis crane vessel

Wärtsilä will supply four retractable steerable thrusters, thruster controls, and two tunnel thrusters for Boskalis’ crane vessel Bokalift 2.

The retraction system, combined with the 8-degree tilted thruster, is said to be a key factor in enabling effective station-keeping. The thrusters’ retractability also enables shallow draft operations, the company said.

Stefan Wiik, vice president, Asset Management Services, Wärtsilä Marine, said: “Wärtsilä’s thruster solutions enable this kind of high specification vessel to operate successfully in sustainable energy installation projects. Furthermore, the energy efficiency of our thrusters reduces fuel consumption, which at the same time limits emission levels.”

Boskalis is converting an existing hull to create the Bokalift 2. The vessel is expected to have 7,500 square metres (80,729 square feet) of free deck space and a crane with a lifting capacity of 4,000 tons and a lifting height of more than 100 metre (328 feet).
