Allseas Group S.A. Wins Contract from Nord Stream 2 AG

Nord Stream 2 AG announced that it has awarded a contract for the offshore pipelay of both lines of Nord Stream 2 to Allseas. The contract is to be signed in the next few days. Allseas will undertake offshore pipelay works for both lines in 2018 and 2019 using three pipelaying vessels: Pioneering Spirit, Audacia and Solitaire.
