In an industry breakthrough, the Moray West project will be the first time XXL monopiles will be installed in the winter period, and DEME will deploy its double-staged, motion-compensated pile gripper, the company said.

Moray West will also be the first time a vibro-hammer is being utilised for the XXL monopiles to overcome weaker soil layers.

As well as the XXL monopiles and transition pieces, DEME will perform the bolting and grouting works for the monopile/transition piece connections.

The floating DP3 offshore installation vessel, Orion, is set to install the monopiles, and the jack-up, Apollo, will be deployed for the installation of transition pieces.

The installation campaigns are slated for 2023 and 2024.

DEME Offshore has been awarded the contract from Moray West, which is principally owned by Ocean Winds, an international company dedicated to offshore wind and created by two energy utility companies, EDP Renewables and ENGIE. A small minority stake is held by UAB Ignitis Renewables.

Moray West will comprise 60 Siemens Gamesa 14.7 MW wind turbines and two offshore substations installed approximately 22.5 kilometres from the Caithness coastline.

First power is expected in 2024, and the wind farm is scheduled to be fully operational in early 2025.
