Metadata: GEOxyz_2025_EA1_OWF_PHYS_SBF_GEO_O_M_MBES
Abstract:
Iberdrola has awarded GEOxyz a contract to provide annual maintenance services to East Anglia One (EA1) during 2025. The Scope of Work (SoW) applies to Iberdrola offshore windfarm sites located within Iberdrolaâ??s UK Hub. The East Anglia One windfarm is situated 43 km off the Suffolk coast and has 102 wind turbines installed on 3-legged jacket foundations and one offshore substation installed on a jacket foundation. The work comprises the provision of inspection, maintenance, and repair services for the windfarmâ??s Balance of Plant (BoP) subsea assets of the Wind Turbine Generator (WTG) foundations (FOU), Offshore Substation (OFSS), and cables. The work overview is described as follows: â?¢ ROV inspection, maintenance, and repair for the wind turbine (WTG) subsea structures (FOU) and the offshore substation (OSS) subsea structures, including j-tubes and cable protection systems. â?¢ Geophysical seabed surveys at the base of the FOU and OSS structures, and along inter-array subsea cable (IAC) routes. Details on requirements can be found in EA1-OAM-LA-IBR-244877 - Rev 01 - East Anglia 1 - Subsea (Geophysical Survey) Task Register. The geophysical seabed survey scope of work encompasses Multibeam Echo Sounder (MBES) and Side-Scan Sonar (SSS) surveys for EA1â??s 102 Inter-Array Cables (IAC) and 103 wind turbine generator (WTG) foundations, performed by GeoSurveyor XXII, to: â?¢ Enable periodic monitoring of scour around the installed subsea structures. â?¢ Assess potential scour damage. â?¢ Provide updated information on the burial status of installed cables.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Expected project start date was 24/08/2025, while the expected end date was 30/09/2025. Data processing and reporting took place at GEOxyz office. Survey was conducted by the GeoSurveyor XXII vessel which was equipped with Kongsberg Em2042 MBES sensor. Software used to record the survey data is Qinsy. |
