Norwegian shipbuilder Ulstein Verft has handed over the world’s largest plug-in hybrid vessel, Color Hybrid, to ferry operator Color Line. With all its innovative and new environmentally friendly solutions, the ship is an important milestone project for both Ulstein, Color Line and the maritime cluster.

Color Hybrid introduces new solutions to reduce noise and emissions. The vessel is a plug-in hybrid, where the five-megawatt batteries can be charged with environmentally friendly power from shore power in Sandefjord. The vessel will go silently in and out of the fjord of Sandefjord without emissions of harmful environmental gases, or nitrogen and sulphur compounds to air in the area.


The battery pack weighs 65 tonnes and can be recharged in one hour. The ship also has a heat reservoir of five megawatts which utilises 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.

Measuring 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, “said Gunvor Ulstein, CEO of Ulstein Group and continues: We would like to express our gratitude to Color Line for a good and constructive collaboration throughout the construction period. We are pleased that the ship is ready for operation and that passengers very soon can experience traveling with Color Hybrid”.

Over 70% of the suppliers are from the maritime cluster in Norway and they represent the highest quality of the maritime industry.

“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, “said Color Line CEO Trond Kleivdal.
