Underdeck mud and slop tanks are now open spaces which could house banks of batteries. With typical Norwegian ingenuity, Norwind wants to equip its vessels with technology similar to shore power, but for plugging into wind turbines. Aure says it may be possible to power all SOV operations this way, using 100% battery power, in future, making offshore operations completely carbon-free. Norwind is planning a series of new SOVs. With this strategy, the company has commissioned nearby shipyard group, Vard. Battery friendly: the DC set-up aboard an ESS-equipped VARD vessel.
