MAN Cryo’s parent company MAN Energy Solutions has also been selected to supply 2 × 9L28/32DF dual-fuel auxiliary engines to each vessel.
Wallenius SOL states that the vessels will run on LNG, making them among the most environmentally efficient vessels in that part of the world.
Upon construction, the vessels will be the largest to ever meet Finnish/Swedish ice class 1A Super standard, ensuring year-round service in the frozen Gulf of Bothnia.
The 242-metre newbuildings will have a sailing speed of 20 knots and a capacity of 5,800 lane metres.
Delivery of the vessels is scheduled for 2021 and the order includes an option for two further vessels.
Louise Andersson, Head of MAN Cryo, said, “These RoRos will operate in a sensitive, sulphur-emission-control area in harsh winter conditions where a reliable LNG fuel-gas supply system is of the utmost importance.”
“We are very pleased that both shipyard and shipowner trust us to deliver the fuel-gas supply system for such unique vessels.”
