Ecosse Subsea Systems has completed a major seabed clearance project on the Laggan-Tormore project west of Shetland on behalf of Total E&P Ltd and its partner Dong E&P (UK) Ltd. The Aberdeen subsea technology company deployed its SCAR1 trenching tool to remove up to 1000 boulders which were delaying progress on cable laying and umbilical installation work. The SCAR1 cut a 10 metre wide swathe over a 67km route, displacing boulders up to two metres in diameter and removing soil to leave a flat seabed for pipe laying to commence.
