Norwegian shipbuilder Ulstein says it has delivered the world’s largest plug-in battery-powered hybrid vessel, Color Hybrid.

The ship was delivered from the company’s Ulstein Verft to Color Line.

The Color Hybrid features new solutions to reduce noise and emissions, including five-megawatt batteries that can be charged from shore power stations in Sandefjord.

Ulstein reports that the battery pack weighs 65 tons and can be recharged in one hour. The ship also has a heat reservoir of five megawatts, utilizing heat from both the wake and the exhaust for heating. “This, together with an optimal hull construction, helps to make the vessel energy efficient and environmentally friendly,” Ulstein says.

Color Hybrid measures 160 m in length and 27.1 m in the beam, the vessel has a capacity of carrying 2,000 passengers and 500 cars.

“Strong focus on innovation and delivering quality to our customers has always been very important to us. With broad maritime expertise, our skilled and committed employees have made a great effort to complete the Color Hybrid, “says Gunvor Ulstein, CEO of Ulstein Group.

According to Ulstein, over 70% of the suppliers in the project hailed from Norway’s maritime cluster, representing an important milestone for all parties involved.

“The construction of the world’s largest plug-in hybrid vessel is in line with the company’s ambitions for further development of sustainable and environmentally friendly solutions for Norwegian shipping, “says Color Line CEO Trond Kleivdal.
