Wärtsilä has committed to a demanding delivery schedule for a thruster solution that will enable Netherlands-based Boskalis to convert an existing hull to create the crane vessel Bokalift 2.

The DP2 crane vessel will have accommodations for 150 persons. Providing 7,500 sq. m of free deck space it will have a crane with a lifting capacity of 4,000 tons and a lifting height of over 100 meters. Straight after delivery the Bokalift 2 will make its debut on the wind project in Taiwan and is suitable for a wide range of projects: offshore wind projects, the installation and decommissioning of oil and gas structures, and salvage work.

Wärtsilä will supply four retractable steerable thrusters and thruster controls, as well as two tunnel thrusters. The proven retraction system, combined with the energy efficient 8-degree tilted thruster, is a key factor in enabling effective station-keeping performance. The thrusters’ retractability also enables shallow draft operations.

“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,” says Stefan Wiik, Vice President, Asset Management Services, Wärtsilä Marine.
