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.
