Transocean Launches Hybrid Floating Drilling Unit

World's First Deployment

Offshore specialist TransOcean has announced the successful deployment of the world’s first hybrid energy storage system aboard a floating drilling unit.
The unique technology captures energy generated during normal rig operation and is expected to boost reliability and break-even for future platforms, spurring breakbulk demand for new installations.
“This first of its kind hybrid power upgrade will further enhance the reliability of our operations, while simultaneously reducing fuel consumption, operating costs and our environmental footprint,” said Jeremy Thigpen, CEO of Transocean.

High-value Wells

The drilling rig Transocean Spitsbergen acted as the site for the first deployment, during its engagement in drilling operations at the Snorre field in Norway on behalf of energy major Equinor.
“We are pleased and proud to work alongside Equinor to jointly identify and implement more efficient and sustainable technology to deliver high-value wells to the industry,” Thigpen said.

Transocean’s investment in the system will be funded in part through fuel saving incentives in its contract with Equinor and by the Norwegian NOx Fund. It is expected that

Reduced Fuel Consumption

The system was developed in partnership with systems integrator and engineering company Aspin Kemp and Associates. Intellectual property for the technology comprise Patent Nos. U.S. 8,373,949, U.S. 9,444,252, U.S. 10,389,113, and others outside the U.S.
Relying on waste energy, the system stores electric in a battery bank on deck and promises to reduce fuel consumption and increase a dynamically positioned rig’s station-keeping reliability.
Based in Vernier, Switzerland, Transocean is the world's second-largest offshore drilling contractor and operates a fleet of 45 mobile offshore drilling units consisting of 28 ultra-deep-water floaters, 14 harsh environment floaters, and three midwater floaters.
