Ground-breaking marine turbine system successfully powers remote subsea drill sites

EC-OG's ground-breaking turbine system harnesses energy within ocean currents to produce autonomous electrical power for multiple applications - including subsea wells. The project with the OGTC provided support to complete FEED work for a North Sea field trial, focused on optimising the deployment and de-risking the installation and operational phases. By successfully integrating renewable energy technologies in to the production process, this delivers a low carbon source of power while reducing overall operating cost.

Industry Value

The SPH lowers the lifecycle cost of subsea fields, with the potential to deliver £200 million in savings for the UKCS - while at the same time reducing carbon footprint.

Key Results

During recent workshop trials supported by a North Sea operator, the SPH was used to power a commercial Subsea Control Module (SCM) and local power distribution system. By operating the SCM using lithium ion battery technology, located within EC-OG's proprietary Energy Storage and Intelligent Energy Management System, the test successfully confirmed the Subsea Power Hub's capabilities for operating North Sea wells without a power umbilical from a topside installation.

Lessons Learned

Critical to operability, the trial successfully demonstrated the full operating range of SCM functions through both SPH operating modes; battery power and battery charging. All testing was completed at Cohort company SEA's facility in Aberdeen, where in April 2018 a previous integration trial was conducted with SEA's pre-commercial SCM which they modified to work on DC power. The most recent test was conducted on the North Sea Operator's SCM, using an AC power supply from the Subsea Power Hub.

Next Steps

To identify a an industry partner and location for a field trial.
