DEME is investing in its first Service Operation Vessel (SOV) for wind farm maintenance in order to be able to offer a total package of services to the offshore wind industry, and the keel laying ceremony for the new vessel took place on 13th December at the CEMRE shipyard in Yalova, Turkey.
DEME holds keel laying ceremony for it’s first dedicated Service Operation Vessel for offshore wind farm maintenance

Conceived by DEME and further designed in close cooperation with Vuyk Engineering Rotterdam and Marin, the new innovative SOV has been designed to significantly improve safety, comfort and workability for wind farm technicians even in the roughest sea conditions. The vessel will feature a Small Waterplane Area Twin Hull (SWATH) design, which ensures low wave impact on movements when approaching the wind turbines, compared to a monohull SOV. It will enable safe crew transfers in significant wave heights of up to 2.5 m, being the first DP2, twin-hulled SOV in the world.

At 60 metres long, the SOV will be equipped with a motion compensated gangway and daughter craft to safely transfer technicians to the wind turbines, increasing the workability and logistics capabilities of the vessel. It is also designed according to the latest comfort standards, allowing the vessel to be a homely offshore base for up to 24 technicians and a nautical crew.

Environmental considerations are an important element of the vessel design with, amongst others, a waste heat recovery system and a Clean Design notation. With the provided DP2 technology  the vessel can hold its position in rough sea conditions but still operate with lower fuel consumption when compared to traditional SOVs. A reduction of fuel consumption up to 50 percent can be achieved compared to a monohull SOV.

“We believe the twin-hulled design, a motion compensated gangway and dynamic positioning is a winning combination and will further reduce the costs of wind farm maintenance, especially compared to large monohulls reaching similar workability” said Michael Glavind, Business Unit Director DEME Offshore. “With this first SOV joining our fleet, we further strengthen our capabilities to offer the full offshore wind package, from installation to maintenance.”

Due for delivery in 2021,  the SOV will be chartered by Siemens Gamesa Renewable Energy as part of a long-term maintenance contract for the Rentel and Mermaid & Seastar (referred as SeaMade) offshore wind farms in Belgium. This is the first SOV to serve three different wind farm sites.
