MAN Cryo fuel gas supply system selected for LNG RoRo newbuilds

MAN Cryo – MAN Energy Solutions’ marine LNG fuel-gas-system manufacturer –has signed the contract to supply the LNG fuel-gas supply systems to Wallenius SOL, the Swedish shipping line.

The technology will be supplied in connection with the building of two RoRo newbuildings in China at Yantai Raffles shipyard, the company said in a statement.

MAN Energy Solutions has also been selected to supply two dual-fuel auxiliary engines to each vessel.

Wallenius SOL states that the vessels will run on LNG. 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-meter newbuildings will have a sailing speed of 20 knots and a capacity of 5,800 lane meters.

Delivery of the vessels is scheduled for 2021 and the order includes an option for two further vessels. Wallenius SOL is a shipping line formed by Swedish concerns Wallenius Lines and Svenska Orient Linien (SOL).

MAN Cryo’s scope of supply for the vessel covers two 685-cbm vacuum tanks including tank connection spaces (TCSs) with LNG fuel pumps, bunker stations with a capacity of 500 cbm/h, automation, emergency shut-down and gas-detection systems.

Under-deck mounted tanks with airlocks allow the amount of fresh air sucked into the tank rooms to be reduced to a minimum. This is an important consideration in the tough winter conditions the ships are set to operate in, where the amount of cold air in the vessels needs to be kept to a minimum.
