J+S Subsea completes first ever work scope in Canada with battery-powered subsea control systems

(WO) – Subsea controls specialist J+S Subsea has announced the completion of a project which represents significant expansion of the company’s international corporate horizons.

The Kintore-based company’s first ever scope of work in Canada has involved the supply of three subsea battery-powered control systems to maintain integrity of the subsea electrical infrastructure when topside electrical power is unavailable.

The project has been delivered through a collaborative approach involving Viper Innovations, Verlume, Richmond Mills Fabrication and MH Engineering (Fife), as well as J+S Subsea.

The scope included the design, engineering, manufacture, marinisation and testing of subsea-deployed systems that will maintain continuous application of Viper Innovations’ cutting-edge V-LIFE technology. 

The patented electrical passivation signal maintains the electrical integrity of the field and satellite extensions 350km off the coast of Canada, while the Floating Production, Storage & Offloading (FPSO) vessel is disconnected from the system during scheduled maintenance. 

The J+S Subsea systems can be recharged on the deck of a Construction Support Vessel (CSV) or onshore, via the supplied charger, and redeployed for a further 90-days. 

Each system consists of a Verlume-supplied subsea battery and separate J+S Subsea control unit housing Viper’s V-SLIM (Subsea Line Integrity Monitor), with mating Electrical Flying Leads (EFL), housed in a steel frame constructed in accordance with DNV regulations.

Central to swift delivery of the time-critical project was the ability to capitalise on the availability of components in J+S Subsea’s Legacy Locker, an open industry portal for the re-use, refurbishment, repurposing and recycling of subsea equipment.

Commenting on the latest news, J+S Subsea Managing Director Phil Reid said, “Our unique and innovative Legacy Locker was pivotal in accelerating turnaround time for this bespoke project. This, combined with our inhouse technical expertise, made us ideally positioned to deliver for our client and underline our strategy of sustained growth.”

Richard Knox, CEO of Verlume said, “Through the integration of our Charge compact subsea battery with the technologies of both J+S and Viper Innovations, we were able to collaboratively solve client power delivery challenges by ensuring reliable delivery of subsea power on the seabed.

“This project comes at a time of significant commercial progress within Verlume, adding another subsea deployment to the many systems that have been installed across the offshore ecosystem worldwide.”
