Wind farm support - SOV/CSOV

Service operation vessels, Construction Support Vessels and Installation Support Vessels are reliable Walk-To-Work (W2W) platforms for wind farm support operations. Our designs include the X-STERN® or TWIN X-STERN™ solutions.

Our wind farm support vessel portfolio consists of innovative working platforms with excellent station-keeping capabilities and low fuel consumption. This group of designs include vessels such as:

  • Service Operation Vessels/ Windfarm Support (SOV/ CSOV)
  • Installation Support Vessels (ISV)
  • Construction Support Vessels (CSV)

Our vision is to create tomorrow’s solutions for sustainable marine operations. Our wind farm support designs are developed for effective access to wind installations offshore, and to ensure safe operations as well as serving comfortable accommodation for the onboard personnel. Together with experienced partners, we are actively putting mutual knowledge together, to bring forward new installation concepts for the offshore wind industry based on simplistic and proven technologies. Our state-of-the-art solutions are prepared with the installation of hybrid power solutions for future carbon-neutral and zero emission operations.

The first generation of these vessels introduced the X-STERN® for reduced slamming in astern operations in-field. The second generation (SX210 upwards) introduced the TWIN X-STERN™ - a ship with two sterns and main propeller units in each end.
