DeepOcean joins Westernlink crew
Contract from Prysmian Group for trenching services on UK HVDC project
DeepOcean UK has been awarded a contract by Prysmian Group for trenching services on the Westernlink project that will carry renewable energy from Scotland to Wales.
The scope of work includes pre-lay survey, pre-lay grapnel run, post-trench survey and trenching of more than 560km of HVDC cabling in water depths of up to 165m.
DeepOcean will use its PCP2 plough (pictured) to trench approximately 425km of cable, which will be deployed from the charter vessel Go Pegasus. Jet trenching of approximately 135km of cable will be performed “from one of DeepOcean’s permanently mobilised trenching support vessels”, the company added.
Offshore work will begin in the second half of the year with campaigns continuing through to 2016.
“We are delighted to be awarded this major subsea contract, the largest in DeepOcean UK’s history. This award highlights our position as a leading contractor of trenching services for long-length cable projects,” said DeepOcean UK managing director Tony Inglis.
Westernlink is a £1bn joint venture by National Grid and ScottishPower Transmission. Prysmian is handling construction in a consortium with Siemens.
Prysmian is responsible for cable installation, including all preparations and reinstatement, while Siemens is responsible for building and commissioning converter stations at each end of the cable, at Hunterston in Scotland and Deeside in Wales.
