DNV and the Norwegian shipping industry partnered to develop battery-powered vessels. Four hybrids, powered by a mix of battery and diesel-electric propulsion, will hit the water this year and next. Eidesvik Offshore’s supply ship Viking Lady will be the first to have a battery package installed this spring. “Hybrid ships are similar to the well-known hybrid cars, like the Toyota Prius,” said Remi Eriksen, CEO of DNV Maritime and Oil & Gas. “A major advantage of these ships is that the payback time on additional investments is expected to be two to four years compared to more than 10 years for cars.” www.eidesvik.no
