Worlds first Twin Hull SOV

Offshore wind farms will have the opportunity to replace generation from fossil energy sources and is seen as an important part of sustainable future energy production. Technology and market development are still at an early stage, the potential for technological development and cost reduction both at sites but also regards to service and operation is estimated to half in cost and double in technology by 2030.

DEME Twin Hull SOV

As a world leader in highly specialized fields of dredging, marine engineering and environmental remediation, DEME is taking a huge step with the new SOV design. The new Twin Hull SOV will feature a Small Waterplane Area Twin Hull (SWATH) design, which ensure low wave impact on movements when approaching the wind turbines. Further, the 60m long vessel will be equipped with a motion compensated gangway and a daughter craft to safely transfer technicians to the wind turbines. The DP2 system installed will ensure the vessel can hold its position in rough sea and still operate with lower fuel consumption. Compared to monohull SOVs the reduction of fuel consumption can be as high as 50%. All of this adds up to reduce the cost of wind farm maintenance and operation.

Due for delivery in 2021, the SOV will be chartered by Siemens Gamesa Renewable Energy and enter a long-term maintenance contract for the SeaMade offshore windfarms in Belgium. The SeaMade consists of three different windfarm sites: Rentel, Seastar and Mermaid concession, with the SOV servicing them all.
