Norwegian shipbuilder Ulstein has launched the worlds largest plug-in hybrid ship at its Ulstein Verft yard. The vessel is now undergoing completion work prior to its delivery this summer. Present at the launch was the site team from Color Line. Several hundred yard workers, in multiple disciplines, are now working with the Color Line crew to complete the vessel before it is put into service between Sandefjord in Norway and Strömstad in Sweden. The ro-pax vessel measures 160m in length and 27.1m in the beam. It can carry 2,000 passengers and 500 cars. The plug-in hybrid vessel can switch to batteries on parts of its journey. According to Ulstein, in this mode the vessel has a very low noise level that can be compared with normal speech, and there are no local harmful emissions. The batteries are recharged via shore connection in Sandefjord, based on green energy.
