Boskalis Installs First Moray West Offshore Substation Platform
Boskalis’ DP installation vessel Bokalift 1 has installed the first offshore substation platform (OSP) at the Moray West offshore wind farm site in Scotland.
The heavy lift operations in the Port of Nigg and on-site were completed safely and successfully, according to the developer Ocean Winds.
As offshore commissioning starts, the previously laid export cable will now be pulled into the OSP.
This is the first of two OSPs the Moray West offshore wind farm will feature. The substations are Siemens Energy’s offshore transformer modules (OTMs), delivered under a contract secured by the consortium of Siemens Energy and Iemants, a subsidiary of Smulders.
Both OTMs were fabricated at Smulders yard with Siemens Energy managing the fit-out of their equipment onto the OTMs from their Manchester base.
The consortium partners loaded out and dispatched the topsides at the beginning of last month, with the OTMs arriving in Scotland by mid-November.
At the end of November, the first batch of transition pieces (TPs), including the two for the offshore substations, arrived at the Port of Nigg in the Cromarty Firth.
Bokalift 1‘s scope of work involves the installation of the J-Tube cages, transition pieces (TP), and topsides for both Moray West offshore substations.
As Bokalift 1 moves to install the second OSP, Bokalift 2 continues to install monopiles on site, as the winter weather windows allow, said Ocean Winds.

Located off the east coast of Scotland in the Moray Firth, the 882 MW Moray West offshore wind farm is developed and majority-owned by Ocean Winds, with Lithuania’s Ignitis Group holding a minority share.
The project will comprise 60 Siemens Gamesa 14.7 MW wind turbines and is scheduled to be fully operational in 2025. Once fully commissioned, Moray West is expected to meet the electricity requirements of about 650,000 households in Scotland for 25 years.

Over the next decade, U.S. offshore wind power is expected to grow from a single 30-megawatt wind farm off Rhode Island to more than 2,000 MW of capacity along the Atlantic Seaboard. There are contracts for wind power off the coasts of Massachusetts, Connecticut, New York, Maryland, New Jersey, Rhode Island, and Virginia.
The National Renewable Energy Laboratory has estimated the United States has over 4,000 gigawatts (GW) of offshore wind potential, enough to power the country four times over.
The growth in part being spurred by state solicitations, including in New York, where then-Gov. Andrew Cuomo (D) set a commitment of 9,000 MW of offshore wind by 2035, and in Connecticut, where in June 2021, Gov. Ned Lamont (D) signed legislation authorizing the construction of 2,000 MW of offshore wind by 2030.
The offshore development is also being driven by an investment tax credit set to end in December 2019 and is equal to 12 percent of expenditures. U.S. Sens. Susan Collins (R-Maine) and Tom Carper (D-Del.) have introduced a bill to extend the tax credit for up to eight years.
The Interior Department has held eight competitive lease sales that resulted in 15 offshore wind leases over 1.7 million acres that has the potential for 21 GW of capacity. In February 2022, the Bureau of Ocean Energy Management completed a bidding process that realized $4.37 billion for 488,000 acres across six lease areas in federal waters off New York and New Jersey.
Projects have also been proposed off the Southeast coast, off California and Hawaii, and for the Great Lakes.
