Genny Hire Ltd has been proud to play a part in a pioneering project that marks the first reported use of flywheel technology to cut emissions on a subsea remotely operated vehicle (ROV).
Working alongside Dumarey Green Power and global ROV specialists ROVOP, the trial integrated a Peak Power 200 flywheel energy storage system with a Forum XLX ROV during onshore testing.
Large ROVs demand a highly dynamic power supply, with sharp spikes needed to start hydraulic power units and operate control systems. Traditionally, this meant ROVOP had to hire in larger generators, adding to fuel use, emissions, and operating costs.
In this case, the Peak Power 200 flywheel was deployed to support ROVOP’s own 500 kVA generator. The flywheel delivered rapid bursts of power — up to 186 amps — exactly when needed. This meant the existing 500 kVA machine could be used without the need for a larger hired unit, reducing costs while maintaining performance.
The results speak volumes:
- Fuel savings of around 322 litres every 50 operating hours.
- Carbon reductions of approximately 43 tonnes of CO₂ annually.
- Cost efficiencies through lower fuel consumption, fewer deliveries, and no requirement for a larger hire generator.
Kelsie, Hire Controller at Genny Hire, said: “This project really shows what Genny Hire is all about — finding the right power solution to meet our clients’ needs. By working closely with ROVOP and Dumarey Green Power, we were able to help deliver a setup that cut costs, reduced emissions and proved that smarter power.”
This collaboration demonstrates how innovative power solutions can help offshore operators cut emissions and costs while supporting ESG targets.
Dumarey Green Power has acknowledged the key roles played by Genny Hire and ROVOP in making the trial possible.
