Concept for large-volume LNG bunker barge unveiled
The design study for the LNG barge has been developed by NLI Solutions, Rolls-Royce and Wilhelmsen Technical Solutions
The concept has been further developed in a design study together with the Marine division of Rolls-Royce and Wilhelmsen Technical Solutions (WTS). For safe operations and increased manoeuvrability, the barge will be equipped with podded propulsion similar to those used in offshore support vessels as well as state-of-the-art electronics for early threat detection.
The NLI LNG tank is an atmospheric, prismatic steel type ’B tank with an LNG capacity of 4000m3. It will be fitted with a new insulation system with very low levels of boil-off gas, according to the involved companies.
Onboard power and propulsion are fed by an environmentally friendly gas engine. The barge has a large pressure tank on the aft deck for boil-off gas handling and gas delivery to engine.
Excess boil-off gas can be delivered to a shoreside gas grid when the barge is not on bunkering operations. The barge can also deliver electric power to a shoreside electric grid.
