UTEC (Acteon’s Geo-services business line) was awarded a three-year subsea balance-of-plant O&M contract by Siemens Gamesa Renewable Energy (SGRE) for the Butendiek offshore wind farm. UTEC’s scope included annual subsea foundation ROV inspections and geophysical seabed survey work, including multibeam echosounder (MBES) surveys of the array cable routes and surveys of OSS/WTG scour protection, plus associated seabed and corrosion-protection survey activities covering the wind turbine generators and the offshore substation.
