Corinth Pipeworks awarded contract by Subsea 7 in Norway

Brussels, 5 April 2022

Cenergy Holdings announces that Subsea 7 awarded to Corinth Pipeworks, its steel pipe segment, a contract to provide High Frequency Welding (HFW) steel pipes for the tie-back of OKEA Hasselmus gas discovery to the Draugen production platform in the Norwegian North Sea via one subsea well.  This will be the first subsea tie-back to the facility executed by OKEA with start-up targeted for the fourth quarter of 2023.  The Hasselmus project is located 7km north-west of the Draugen platform.

This award to Corinth Pipeworks is the latest coming from Subsea 7 and builds on the success of a string of earlier pipeline developments.  As per the previous successful product supplied by Corinth Pipeworks for tie-backs, the 10km of 12” HFW linepipe for Hasselmus will be manufactured and coated in ultra-long lengths at Thisvi facility, Greece and delivered directly to Subsea 7’s spoolbase in Vigra, Norway, where fabrication will take place for subsequent offshore reel-lay installation.  Offshore operations will be executed in 2022 and 2023.

Corinth Pipeworks has worked closely with Subsea 7 over the years to develop the optimized longer

length solution allowing early decision making and accelerated delivery time, ultimately cutting project costs and improving schedule.

Hasselmus is yet another milestone in the company’s growing offshore presence with end-users and lay-contractors recognizing the value in the latest welded pipe technology for critical offshore applications.  Corinth Pipeworks has built a strong track-record in successful execution of offshore linepipe projects in global markets.  The technology-driven cost reduction measures it introduced enhance upstream tie-back project developments like Hasselmus and allow them to remain an important part of the future energy mix.
