MPI Workboats has been awarded two long-term contracts with Statoil on the Dudgeon Offshore windfarm.
Both MPI Napoleon and MPI Snowball will be providing crew-transfer support with the first vessel having commenced its contract earlier this month.
Meanwhile, the second vessel will start a three-year contract later on in the year.
The Dudgeon Offshore windfarm is a £1.5billion project which is expected to harness offshore wind to power more than 410,000 homes.
It will be located 20 miles off the North Norfolk coast and will begin generating electricity next year.
