Description

MMT was contracted by Statoil to undertake a geophysical and benthic survey for the Hywind Offshore Windfarm – Seabed and sub-seabed mapping of development site and export cable corridor.

The scope of work included seabed and sub-seabed survey of the Hywind Offshore Windfarm development site and the export cable corridor. The main aims with the survey were to:
 Acquire and interpret high quality seabed and sub-seabed data for project planning and execution, including shallow geology, bathymetry, seabed sediment distribution and detection of seabed features and seabed obstructions.
 Detect possible occurrence of benthic habitats and species of known conservation importance.
 Improve the geological understanding of the shallow stratigraphy and sediment properties in the turbine site and export corridor to facilitate the planning and execution of turbine foundation installation and cable routing, installation and protection.
 Detection of three cables.

The Hywind Offshore Windfarm site is located on the east coast of Scotland at the Buchan Deep site, approximately 25 km east of Peterhead (Figure 1). The development will consist of five floating wind turbines, anchored to the seafloor each with connection to an export cable.
The survey area is divided in two main parts; the turbine site area with accompanied construction and anchoring areas and the export cable corridor.
The development area is approximately 60 square km but is limited by the Forties pipeline exclusion zone (2000 m wide) running in a NE-SW direction (Figure 1). The export cable corridor is 25 to 30 km long and 500 m wide, with a planned landfall in the Peterhead area. The turbine site area has water depths in the range of 110 to130 m.
