Subsea construction vessel (OSV) North Sea Giant managed by North Sea Shipping has installed a Yaskawa Environmental Energy / The Switch solution that will allow the vessel to switch between its diesel engines, allowing it to run just one of its diesel engines during operations, rather than the standard three it has previously used.
The solution is based on a unique Electronic Bus Link (EBL) from Yaskawa Environmental Energy / The Switch. It works by connecting the vessel’s DC-Hubs and the diesel engines, permitting ongoing operations, even if a critical fault occurs. It promises reduced maintenance and downtime, cost savings, and lower emissions.
Asbjørn Halsebakke, general manager, Yaskawa Environmental Energy / The Switch Norway explains: “It does this by splitting the on-board grids in a matter of microseconds, isolating faults and protecting the complete operational system. This offers significant savings on maintenance costs. Also, by rapidly connecting and disconnecting energy sources from one another, including batteries and engines, they can be optimised for efficiency. This eliminates the need for the operator to run three different units during all operations, saving on long-term fuel costs and reducing emissions.”
According to Mr Halsebakke, this is the first vessel in the world approved to run a DP3 class dynamic positioning system with one engine and batteries.
The Switch technology, supplied as part of a broader Wärtsilä solution, was installed in Haugesund, Norway, after a program of rigorous testing supervised by DNV GL.
Mr Halsebakke says the company expects many more EBL orders from a range of marine customers, including offshore vessels, ferries, rigs, and tankers
“Every type of ship can benefit from this technology, and we’re sure it will make a real impact in the marketplace,” Mr Halsebakke added.
