Norwegian Electric Systems (NES) has signed its first energy storage solution contract with ship owner Skansi Offshore. The battery pack, a 20in containerised solution, will be installed on board Skansi offshore platform supply vessel Sjoborg. The battery pack will provide enough power to supply the entire vessels requirements should a generator failure occur during DP operations, and the vessel will be able to move safely away from hazardous areas of operation under battery power alone. Furthermore, the battery pack will allow the vessel to use fewer diesel generators during transit, offering peak shaving capabilities and acceleration assistance. During visits to the quayside the battery pack can also utilise shore power for charging, or supplement the shore connection if higher onboard power demands are needed. Energy storage solutions have been part of Norwegian Electric Systems strategy for some time, but convincing ship owners to upgrade their vessels has not been easy, said Paul Winson, senior vice president of NES. Many companies are still sceptical about using batteries on board their ships. This is understandable with the amount of media attention surrounding battery fires on aeroplanes, cars and mobile phones. However, the marine class societies and battery suppliers have gone to great lengths to ensure the safe use of batteries on marine vessels.
