InterMoor’s Marine Project team in Aberdeen successfully recovered the Ocean Power Technologies PowerBuoy after a 7-month trial in harsh North Sea winter conditions.

North Sea operators BP, Shell, and Total have begun an effort to fuel their platforms using sustainable power sources through a connection with Norway’s onshore power grid, which is driven almost wholly by renewable energy.

By using the four converter-battery systems, the operator estimates it will be able to reduce the runtime of the rig’s on-platform diesel engines by 42%, cutting CO2 emissions by 15% and NOx emissions by 12%.

The hybrid power technology cuts fuel consumption and boosts the dynamically positioned rig’s station-keeping reliability, the drilling contractor says.

The engineering company Cosmodyne will work directly with the utility company and its EPC contractor for the project, which will utilize its LINEX natural gas liquefier.

Subsea power demand is growing to support various processing loads, including pumps and compressors. This paper presents a modular direct-current electrical-power system that is designed for use in a subsea field with medium or long step-out distance
