Germany's TT-Line has pledged to have the most environmentally friendly ro-pax in the Baltic through a new Chinese order.
It has inked a deal for one firm vessel, with one option attached, at Jiangsu Jinling.
The so-called Green Ship is due in 2022.
The 230-metre vessel will reduce emissions by more than 50% without having to slow-steam, it said. It can be powered by LNG.
