Moray West OWF Set for Geophysical and Geotechnical Site Investigations


Offshore geophysical and geotechnical investigations at the Moray West offshore wind project site in Scotland will soon begin.

The survey will be carried out at the site on the Smith Bank in the Outer Moray Firth, approximately 22.5 kilometers from the coast of Caithness, covering an area of ​​approximately 225 square kilometres.

Work is expected to begin July 19, 2022 at the earliest and the duration of the investigation is expected to be around six weeks.

The survey consists of two parts. For the first part, a geophysical survey will be conducted comprising a hull mounted Multibeam Echo Sounder (MBES) and Subbed Profiling System (SBP), with towed Side Scan Sonar (SSS) and Magnetometer and arrays 2D seismic.

In the second part, about 85 geotechnical sites will be subjected to cone penetration tests and vibro-coring.

Site investigation operations will be carried out by Gardline’s Ocean Observer survey vessel while Titan Surveys’ Titan Discovery will tow geophysical equipment (SSS and 2D seismic array).

The investigations of coastal geophysical sites along the export cable corridor of the project were conducted in June.

Moray West will include up to 85 turbines, two offshore substations and a total of 65 kilometers of export cables that will transport power from the project to a landing point east of Sandend Bay on the coast of ‘Aberdeenshire and further to the land substation.

The 850 MW offshore wind farm is expected to produce its first electricity in 2024.

Ocean Winds, a 50-50 joint venture between EDP Renewables (EDPR) and ENGIE, is developing the Moray West project.

Earlier this week, the project was awarded a contract for difference (CfD) by the UK government, along with four other offshore wind farms.
