Siemens Gamesa celebrates delivery of Hydrogen ready SOV

Siemens Gamesa has celebrated the delivery of a new Service Operations Vessel (SOV) named REM Energy, which is technically ready to operate emission free with the use of fuel cells and battery technology.

The ship was delivered from the Norwegian shipyard Green Yard Kleven on December 3, 2021 and was christened there in mid-November. Siemens Gamesa has chartered the REM Energy for 4 years, and will be operated by the shipping company REM ENERGY AS. The home port for the service operations will be Bremerhaven. REM Energy will be deployed on Global Tech 1 and Trianel Borkum West wind projects.

The vessel is almost 90m long, 20m wide and will be the workplace and living quarters for up to 75 offshore service technicians and 24 crew members. It is ready for the addition of a 12 MW, battery which would reduce energy consumption during operation. REM Energy is also capable to run emissions free on green hydrogen or with batteries and offshore charging. However, until a green hydrogen economy is established in Germany, the ship will be conventionally powered by diesel generators.

REM Energy is equipped with azimuth thrusters which can be rotated 360 degrees around the vertical axis, enabling it to move between the wind turbines even in rough seas. The ship has a gangway that stabilises the wave movements and enables the technicians to transfer from the ship to the offshore wind turbine. The offshore service technicians will live on board and work in shifts. The Siemens Gamesa crew will rotate every 14 days, while REM Energy itself is able to operate at sea for a total of more than a month before having to return to port again.

"The REM Energy is setting new standards in terms of occupational safety, sustainability and efficiency," commented Stephan Hauhs, Managing Director of Siemens Gamesa Renewable Energy Deutschland GmbH in Bremerhaven. "With the new SOV, we will be able to optimize the service we are providing for our customers. We will increase the availability of the offshore turbines, thereby reducing the cost of electricity and ensuring more clean energy while increasing the safety for our offshore service technicians."

“We are taking the first step in getting ready to cut our emissions in offshore service operations. The commissioning of the REM Energy is a strong signal highlighting the availability of clean technology to facilitate operation without emissions,” said Jonas Pagh Jensen, Sustainability Specialist at Siemens Gamesa. “Governments, industry and investors now need to partner up quickly to ramp up a green hydrogen infrastructure to facilitate the decarbonization of marine shipping.”
