ABB to Provide Energy Storage Solution for DONG Energy’s SOV

ABB will install Onboard DC Grid power distribution onboard Louis Dreyfus Armateurs’ (LDA) wind farm Service Operation Vessel (SOV) to enable the cost-efficient integration of batteries.

ABB’s Power and Energy Management System (PEMS) is said to enable lean operation with fewer running generators without compromising on safety, meaning less maintenance and better fuel consumption over the long-term.

“Shipping is waking up to the many advantages of energy storage,” said Juha Koskela, Managing Director of ABB’s marine and ports business.

“With the industry starting to use batteries more and more, and fuel cells becoming a viable option, we fully expect the Onboard DC Grid to gain further traction.”

The Onboard DC Grid will integrate two sets of batteries used primarily for spinning reserve and peak shaving. Power peaks during operation can be covered by the battery rather than starting another engine. Again, battery power can act as backup for running generators, reducing the need to run spare generator capacity. In addition to ship efficiency gains, the mode of operation has long-term benefits for ship engines, as it increases efficiency through higher engine load and reduces running hours overall, ABB said.

“This project shows how energy storage is a cost-effective solution that maximize energy efficiency and safety,” said John Olav Lindtjørn, Global Product Manager for Onboard DC Grid at ABB Marine & Ports.

“Energy storage can be used for many purposes onboard; sometimes it serves as the sole energy source but for this windfarm vessel it is being deployed as an effective supporting element for the main engine.”

The LDA ship is under construction at the Cemre Shipyard in Turkey. The vessel design is a SOV vessel by Salt Ship Design.

Once delivered in 2018, the new LDA SOV will operate for Dong Energy Wind Power AS on four wind farms off the German coast – Borkum Riffgrund 1&2, and Gode Wind 1&2 – and will enable the maintenance of wind turbines by wind farm technicians.
