Eidesvik cuts installed power with hybrid OSV

A battery system was installed on the 5,381gt vessel at Westcon Yards in Ølensvåg. The system, designed and engineered by Wärtsilä, is connected to a DC hub from The Switch (recently renamed Yaskawa Environmental Energy), which enables the remaining three generators to run at optimal efficiency while batteries take up any excess power demand.

“A generator is one of the most vital components for producing energy on board a vessel,” said Asbjørn Halsebakke, general manager Norway, Yaskawa Environmental Energy. “The shipowner therefore required technology that was not only trailblazing in terms of the benefits it delivers, but also proven, effective and reliable.”

The solution allows the shipowner to reduce operating costs, fuel consumption and emissions associated with the removed generator. The retrofit project took only 14 weeks from initial discussions to completion, compared to a more usual schedule of between four and six months.

While in this case the DC Hub is connected to generators, it can be used in conjunction with renewable energy and alternative power sources if Eidesvik chooses in the future.
