AKOFS Offshore’s AKOFS Seafarer well intervention vessel has been upgraded with Siemens BlueVault Energy Storage Solution.
AKOFS Seafarer is the first existing well intervention vessel to be upgraded with a battery solution, the company said.
The delivery will include Siemens BlueVault Energy Storage Solution including batteries from the company’s new production facility in Trondheim. The modification will increase the vessels DP operating capability, improve the safe operation of the vessel in addition to reducing the fuel consumption in several operation modes.
“This contract shows the benefits of implementing batteries in the electric power supply system in both newbuilds and retrofitted offshore vessels. In operation these vessels have a very variable power consumption in DP mode and operations. Batteries and advanced power electronics leads to significant reduction of fuel consumption, climate emissions and maintenance cost for these vessels,” said Ketil Aagesen, head of Sales at Siemens Marine in Norway.
AKOFS Seafarer is designed to perform subsea well clean-up and testing and riser-based intervention down to 2,500 meters sea depth.
The vessel will from 2020 operate under a five years contract with Equinor for light well intervention services on the Norwegian continental shelf.
