Keel laying ceremony for DEME’s first dedicated Service Operation Vessel for offshore wind farm maintenance.

To be able to offer the total package of services to the offshore wind industry - from installation to maintenance - DEME is investing in its first Service Operation Vessel (SOV) for wind farm maintenance. Concepted by DEME and further designed in close cooperation with Vuyk Engineering Rotterdam and Marin, this innovative vessel significantly improves safety, comfort, and workability for wind farm technicians even in the roughest sea conditions. The keel-laying ceremony took place on December 13 at CEMRE SHIPYARD in Yalova, Turkey.

The SOV 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 mono-hull SOV. The vessel 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 m 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.

“This project is a milestone in the Offshore Windfarm industry for the sector’s long-lasting environment-friendly future plans. In terms of the vessel’s design and efficiency, it can be clearly seen its twin-hull design is particular in its kind.  Along with the DP2 technology and motion compensated gangway, SWATH Service Operation Vessel NB72 is going to be a pioneer for the future of the Offshore Wind Market…” says Orhan Gulcek, Chairman of the Board, Cemre Shipyard.

“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,” says 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.”


Cemre Shipyard, with modern facilities, is one of the leading new building shipyards located in Turkey.

Considering the interest in diversity, Cemre has the ability to build different types of vessels as fishing, offshore and passenger. These highly technologic, eco-friendly and, innovative projects need flexibility and intense care; besides that, tailor-made projects like these are among the distinguishing reasons of Cemre’ s success.

Cemre Shipyard has 3 slipways which enable the shipyard to build 8 to 12 vessels at the same time according to their sizes; in other words, 8 vessels can be and are delivered annually.

Investments never end here. Second Shipyard area has an equipped closed production area that improves the quality and capacity of steel processing.

From the beginning till now all of the delivered and ordered vessels are exported and are built for European customers such as Norway, Iceland, United Kingdom, France, Ireland, Belgium, Denmark, etc. As a consequence, Cemre Shipyard has held its place among the top exporters of Turkey since 2008; and with this responsibility, Cemre works harder for a sustainable organization.
