The contract includes the use the Seacat Ranger, which will be deployed to the offshore windfarm from August this year.
The 336MW wind farm is currently under construction.
The Seacat Ranger will be responsible for technician and equipment transfers, in support of planned maintenance and performance optimisation taking place during the first three years of operations at Galloper.
From September, the catamaran will be joined by the Seacat Liberty and Seacat Vigilant, which will also be based out of Harwich and operating on the site. All three vessels have been built in the UK by South Boats IoW.
As growth in the UK offshore wind market continues, 80% of the Seacat Services fleet is currently deployed in domestic waters, with a large proportion based on the east coast.
Ian Baylis, managing director, Seacat Services said: “Close collaboration in vessel deployment can yield an extensive range of benefits for all of the parties involved in the development and operation of technically and logistically complex offshore wind farms.
“With the drive to optimise efficiency and get the most out of maintenance budgets, the ability to take a more versatile approach – and share project resources – will provide project operators, developers and OEMs alike with a more practical means of meeting collective goals.”
