ABB, a power and automation technology group, has released a third-party verification that its Onboard DC Grid helps vessels reduce their fuel consumption, cut noise and trim their environmental impact.

The measurements and tests, conducted by Pon Power in collaboration with ABB on Myklebusthaug Offshore’s platform supply vessel Dina Star, identified reduction of specific fuel oil consumption of up to 27 percent.

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 percent.

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 Onboard DC Grid’s effect on engine room noise levels.

Tests showed 30 percent noise reduction, contributing to improved working conditions aboard the vessel.

“Noise and vibration reduction has already been a focus of ours for years with our GenFlex Design solution.

The ability now to document this level of fuel efficiency alongside the noise reduction is a very important new step for us as a power solution provider, especially for our customers operating in challenging conditions”, said Ole Knarberg, Commercial Director for the Marine segment in Pon Power Scandinavia.

Dina Star is powered by four Caterpillar 3516 engines in combination with a C32 in a variable speed application.

ABB introduced the Onboard DC Grid power distribution system in 2011.

Platform support vessel Dina Star, delivered to Myklebusthaug Management by Kleven Yard in 2013, is the first vessel powered by the Onboard DC Grid.
