The trials, supported by the Oil & Gas Technology Centre (OGTC), showed the Subsea Power Hub was capable of powering a commercial Subsea Control Module, as well as a local power distribution system.

An Aberdeen-headquartered company, EC-OG, has successfully completed a test programme demonstrating the capability of its Subsea Power Hub.

The trials, supported by the Oil & Gas Technology Centre (OGTC), showed the Subsea Power Hub (SPH) was capable of powering a commercial Subsea Control Module (SCM), as well as a local power distribution system.

By operating the SCM using lithium-ion battery technology, EG-OC said the test successfully demonstrated the Hub’s ability to operate North Sea wells without the need for a power umbilical from a topside installation.

Primarily, the objective of the trial was to establish whether the SPH could supply a reliable degree of power to the SCM and associated subsea infrastructure.

The SPH combines the company’s core technologies – subsea energy storage and power generation – to help solve the issue of energy delivery for remote subsea architecture.

The test was completed using a 3rd Generation Aker Solutions Subsea Control Module, with power delivered via a subsea distribution unit.

Commenting on the trial success, EG-OG’s business development manager, Paul Slorach, said: “This is a big step forward for EG-OC, to be able to have our energy storage system successfully provide power to a commercial SCM.

“Demonstrating the capabilities of lithium-based batteries for powering subsea wells is a great achievement for us. It would have been very difficult to achieve this milestone without the continued support from the North Sea operator and the Oil & Gas Technology Centre.”

 Christopher Pearson, marginal developments solution centre manager at the Oil & Gas Technology Centre, said: “The industry is going through a transition to a lower carbon future and we must support the development of new energy integration technologies that meet the needs of this challenge. 

“EC-OG’s Subsea Power Hub (SPH) contributes to this industry change through its tidal turbine system, which can be used to unlock the huge potential in marginal developments by providing a primary energy source. We are delighted to be supporting EC-OG with their trial, which was a great success and look forward to working with them on the next stage of their project.”
