Danish shipping company Esvagt is to provide MHI Vestas with two service operation vessels for the 860MW Triton Knoll and 731.5MW Borssele 3&4 offshore wind farms off the east coast of England and off the Netherlands, respectively.
The contracts will run for up to 15 years and include an option for a third SOV for the 950MW Moray East offshore project off the coast of Scotland.
Esvagt will collaborate with Havyard on the 831L design for the two 70.5-metre vessels, which will have accommodation for up to 60 people.
The ships will also be equipped with compensated walk-to-work gangways and daughter craft specially designed by the company.
MHI Vestas chief operating officer Flemming Ougaard said: “We build on many years of strong, innovative collaboration with Esvagt. The combination of our shared knowledge will ensure a competitive and efficient green energy production for many years to come.”
Esvagt chief commercial officer Soren Karas said: “We are proud to continue our close partnership, and together with MHI Vestas set the standard for innovation and long-term solutions.
“We look forward to presenting 831L as yet another customised SOV, in which we combine the client’s needs with our competencies and experience in order to guarantee the most optimal and cost-efficient solution.”
MHI Vestas and Esvagt have co-operated for the last eight years, including on the Belwind 1 and Nobelwind 1 offshore wind farms off Belgium.
Esvagt currently has five SOVs and a sixth in production. The two new vessels will raise the total to eight.
