Dutch maritime giant Boskalis has proudly announced the successful completion of its operations for the Ocean Winds’ Moray West offshore wind farm, marking a significant milestone in the renewable energy sector. Over the course of two years, Boskalis deployed a fleet of six vessels to fulfill its contractual obligations in Scotland, demonstrating its expertise and commitment to sustainable energy projects.
The scope of Boskalis’ contract involved crucial tasks essential for the successful establishment of the wind farm. Prior to installation activities, Gardline conducted extensive geotechnical and geophysical surveys to assess the seabed conditions, ensuring the safe and efficient execution of subsequent operations. Subsequently, Boskalis’ subsea rock installation vessel, Rockpiper, meticulously laid over 110,000 tons of rock, serving as scour protection for the 62 XXL monopiles designated for installation.
Boskalis took charge of the installation of 62 monopiles, with DEME securing the contract for the remaining foundations. To transport the foundations, Boskalis utilized its semi-submersible heavy transport vessel, White Marlin, which made two voyages from Asia to the port of Invergordon, Scotland. Upon arrival, Boskalis’ crane vessel, Bokalift 2, seamlessly facilitated the transfer of the monopiles, each weighing between 1,515 to 1,935 tonnes, before deploying them in the designated field through vibro-driving and hydraulic impact driving techniques.
Furthermore, Boskalis’ crane vessel, Bokalift 1, played a pivotal role in the installation of the wind farm’s two offshore substation platforms. These platforms, comprising transition pieces, topsides, and additional equipment, are vital components of the offshore infrastructure, enabling the efficient transmission of generated wind energy to the mainland grid.
