Tests confirm high fuel savings
The platform support vessel (PSV) Dina Star, delivered to Myklebusthaug Management from Kleven Yard in 2013, is the first vessel powered by the Onboard DC Grid
The measurements and tests, conducted by Pon Power in collaboration with ABB on Myklebusthaug Offshore’s platform supply vessel (PSV) Dina Star, identified reduction of specific fuel oil consumption of up to 27%, ABB said. These are the first documented results from a vessel outfitted with ABB’s Onboard DC Grid, which allows engines to run at variable speeds for top fuel efficiency at each load level.
The tests also measured fuel consumption in dynamic positioning operations during challenging weather conditions, identifying fuel savings of 14%. Dynamic positioning operations, where computers automatically maintain a vessel's position and heading, account for a considerable portion of a typical offshore vessel’s operational profile.
In addition to fuel consumption, Pon Power and ABB measured the system’s effect on engine room noise levels. Tests showed 30% noise reduction, contributing to improved working conditions on board the vessel.
ABB introduced the Onboard DC Grid power distribution system in 2011. It was granted “Approval in Principle by American Bureau of Shipping” in January 2014.
