Boskalis completes Moray West offshore wind farm scope

Boskalis announced today the completion of its scope of activities for Ocean Winds’ 882 MW Moray West offshore wind farm, located off the east coast of Scotland in the Moray Firth.

Boskalis was contracted by Ocean Winds ( 50/50 partnership between EDP Renewables and ENGIE) to carry out the offshore geophysical site survey, also including an UXO survey, monopile foundation installation, and the installation of the two offshore substations.

During the execution of the Moray West project, a large part of Boskalis’ unique capabilities and specialisms were brought together. Over the past two years, Boskalis says it deployed six Boskalis vessels. Boskalis’ Gardline colleagues carried out extensive geotechnical and geophysical survey works prior to the installation work. In later phases, Boskalis’ subsea rock installation vessel Rockpiper installed more than 110,000 tons of rock as scour protection for the 62 XXL monopiles.

Its semi-submersible heavy transport vessel White Marlin transported two times eight foundations from Asia to the port of Invergordon, Scotland. From there, Boskalis’ crane vessel Bokalift 2 picked up the monopiles, with weights varying from 1,515 to 1,935 tons, prior to installing them in the field by means of vibro-driving as well as hydraulic impact driving. In addition, Boskalis’ crane vessel Bokalift 1 installed the wind farm’s two offshore substation platforms, consisting of transition pieces, topsides and additional equipment.

Moray West offshore wind farm will comprise sixty Siemens Gamesa SG 14-222 DD 14.7 MW wind turbines and 2 substations on monopile foundations and will have the capacity to power the equivalent of up to 640,000 UK homes.
