ABB say that the first documented results from Onboard DC Grid vessel confirm considerable fuel and noise reduction through the use of its Onboard DC Grid, where engines to run at variable speeds for top fuel efficiency at each load level. ABB explain that its Onboard DC Grid represents a breakthrough for the maritime industry in optimized propulsion by distributing power through a single DC circuit providing significant power savings while also improving the safety and redundancy compared with traditional AC systems. up to 27 percent. The tests also measured fuel consumption in dynamic positioning operations during challenging weather conditions, identifying fuel savings of 14 percent.
