MAN to supply LNG systems for Swedish RoRos
MAN Energy Solutions has also been selected to supply two 9L28/32DF dual-fuel auxiliary engines to each vessel which will be the largest to meet Finnish/Swedish ice class 1A Super standard, ensuring year-round service in the frozen Gulf of Bothnia.
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,” she added.
The 242m RoRos will have a sailing speed of 20 knots and a capacity of 5,800 lane metres. Man Cryo’s scope covers two 685m3 vacuum tanks including tank connection spaces with LNG fuel pumps, bunker stations with a capacity of 500m3/h and automation, emergency shut-down and gas-detection systems.
Under-deck mounted tanks with air locks allow the amount of fresh air sucked into the tank rooms to be reduced, an important consideration in the conditions the ships are set to operate in, where the amount of cold air in the vessels needs to be kept to a minimum.
Delivery is scheduled for 2021 and the order includes an option for two further vessels.
