The contract, with Norwegian oil firm Statoil, will use the Rix Leopard and Rix Lion vessels carry technicians to and from the Dudgeon wind farm which is currently under construction around 20 miles off shore from Cromer.
The Rix Leopard, which is the newest and biggest wind farm service vessels in the company’s fleet, can carry a crew of up to 24 technicians, while the Lion can carry 12.
Jamie Doyle, managing director of Rix Sea Shuttle, said: “We are very pleased to have won the contract with Statoil.
“It was a hard fought tender but the quality and size of our vessels prevailed.”
Work for the contract begins in August and runs for 14 months, with the option to extend for future work.
Doyle continued: “The Dudgeon wind farm is a very exciting development and we are extremely pleased to be a part of it.
“It is fantastic news for Norfolk, bringing a thriving industry and jobs to the region, and the UK renewables industry as a whole.”
