SOV for Deutsche Bucht offshore windfarm enters the water
Esvagt’s new SOV for the Deutsche Bucht offshore windfarm will service MHI Vestas turbines

The service operation vessel for the Deutsche Bucht offshore windfarm in Germany was launched earlier this month.

Due to service the MHI Vestas Offshore Wind turbines on the German windfarm, Esvagt Albert Betz is a fuel-efficient service operation vessel (SOV) designed by Havyard in Norway. It is being built by Zamakona shipyard Spain, which has a longstanding relationship with the Danish shipowner.

The SOV is due to enter service in August 2019 and will operate in support of the Deutsche Bucht offshore windfarm on a 15-year contract between Esvagt and MHI Vestas.

The SOV will be equipped with a walk-to-work gangway system with a bespoke tower with a crane placed on top of the tower. Together with Esvagt’s safe transfer boats (STBs) they will be used to transfer personnel from the vessel to wind turbines.

Esvagt's chief operating officer, Kristian Ole Jakobsen, said the ship “is optimised in accordance with the client’s wishes.”

Speaking at the time that the vessel was ordered, Mr Jakobsen said MHI Vestas had prioritised a fuel-efficient ship. “We are proud to be able to deliver a vessel of this size with remarkably low energy consumption,” he said, noting that the STBs will be able to make port calls independently of the vessel, thus further reducing its environmental impact.

Havyard, the designer of the vessel, said it will have particularly low levels of fuel consumption thanks to using diesel-electric propulsion and a hydrodynamically optimised hullform. Havyard group companies including Norwegian Electric Systems and Havyard IAS will provide key equipment and components for the vessel.

With a length of 58.50 m and beam of 16.60 m the vessel will be fitted with a walk‐to‐work gangway system from SMST. The ship has accommodation for up to 42 people.

The shipyard said the vessel is designed to transfer personnel in a significant wave height of 3.0 m with a current of 0.75 m.
