The system is now operational on the Transocean Spitsbergen rig, engaged in drilling operations at the Snorre field in Norway.
Transocean said that its patented hybrid power technology, developed in partnership with Aspin Kemp and Associates, reduces fuel consumption and increases a dynamically positioned rig’s station-keeping reliability by capturing energy generated during normal rig operations that would otherwise be wasted, and storing it in batteries.
This energy is then used to power the rig’s thrusters.
This important operational and safety enhancement targets a 14% reduction in fuel use during normal operations, leading to a significant reduction in NOx and CO2 emissions, according to the rig owner.
Transocean’s investment is funded in part through fuel saving incentives in its contract with Equinor and by the Norwegian NOx Fund.
Jeremy Thigpen, CEO, said:
- This 1st 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;
- 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.
Siemens said BlueVault, the company’s advanced lithium-ion battery-based solution, would be installed on Northern Drilling’s West Mira offshore drilling rig set to operate in the Nova Field, approximately 120 km northwest of Bergen in the North Sea.
