Briggs Marine has won an eight year contract from DONG Energy for contingency and repair of export and array cables for offshore windfarms in the UK and Northern Europe.
The deal will cover nine sites in Britain, five in Denmark and four in Germany.
Briggs has formed a strong relationship with DONG Energy since last year when it provided interim repair capability for their UK windfarms.
The new framework agreement will run for a fixed period of five years with the possibility of extending the contract for three years.
Collieson Briggs, managing director of the Briggs Group, said: “Concluding an agreement of this magnitude is a great achievement for our offshore cables business and our ongoing relationship with DONG Energy is a testimony of our experience in this area.
“I am delighted with the news of this significant win and extending our working relationship with a company like DONG, an established leader in offshore wind energy.”
