Siemens Gamesa taps Acteon for subsea services at German offshore wind farm

UTEC, a geo-services brand in Acteon’s Data and Robotics division, has been awarded a contract by Siemens Gamesa Renewable Energy (SGRE) to provide subsea balance of plant operations and maintenance (O&M) services to the German Butendiek offshore wind farm.

Under the three-year contract, Acteon will perform annual subsea foundation remotely operated underwater vehicle (ROV) inspections, inter-array cable and foundation seabed survey, and corrosion protection survey covering the wind turbines and the offshore substation.

UTEC will carry out an echosounder (MBES) seabed survey of the inter-array cables and the offshore substation/wind turbine scour protection while Deepwater’s Polatrak Drop Cell – DC II equipment will be used for the corrosion protection survey.

“Following the success of subsea surveys and inspections for the Coastal Virginia Offshore Wind pilot project, Acteon is proud to be working with Siemens Gamesa again. This partnership will ensure that the asset owner experiences safe optimised inspection scheduling and more efficient resource utilisation,” said Tim Eyles, Vice President of Acteon.

Butendiek, located 32 kilometers off the island of Sylt, and 53 kilometers from the German mainland, is owned by a consortium consisting of CITIC Pacific Limited, Industriens Pensionsforsikring, ITOCHU Corporation, Greencoat Renewables, Octopus Energy Generation, and wpd.

The wind farm consists of 80 Siemens wind turbines with a capacity of 3.6 MW each. Construction started in early 2014 and the 288 MW wind farm was completed in 2015, providing the equivalent of 370,000 households with renewable energy.
