Aberdeenshire-based Ecosse Subsea Systems (ESS) was last year awarded work to carry out trenching work ahead of cable-laying on the Wikinger project in the Baltic Sea.
The company has now seen the scope of the contract with main contractor Prysmian Group significantly increased with work added to clear the seabed for the 70-turbine wind farm.
Keith McDermott, ESS commercial director, said detailed surveys of the seabed discovered a number of obstacles on the proposed route. The firm will now carry out seabed clearance and route preparation prior to starting the trenching work.
“This is an area in which we have a great deal of experience and strong track record of working in different terrains,” he added.
Meanwhile, Aberdeen-based mechanical engineering firm EnerMech has started work on a £5 million-plus contract to work on a turret system for BP’s Glen Lyon floating production storage and offloading (FPSO) facility off Shetland.
