The project not only demonstrates safe installation of lithium-Ion batteries on an offshore drilling rig but also enables safer operation and increased reliability for station keeping, according to Canadian-based AKA. Additional benefits lie in the optimization of how the diesels are run which saves fuel and reduces environmental impact.
AKA’s full scope of supply for the Spitsbergen hybrid system includes the conversion to DP3 closed-bus operation and the addition of 5.6 megawatts of hybrid power. The thrusters can operate completely independently of the main generators and distribution system allowing the main generators to be fully optimized to the load and simultaneously reducing DP station keeping risk.
Jason Aspin, CEO of Aspin Kemp & Associates, said, “The AKA Energy Storage System at the thrusters is a new way of making the vessels substantially safer by keeping them in position even during a potential failure of the power plant. This prevents them from drifting off the drilling location which endangers the people who work on these rigs and our environment."
Aspin said, “This project is a step-change in the way industry views currently operating drilling rigs. It demonstrates that these rigs can be converted to safer, more reliable and environmentally-responsible operations without incurring downtime.
