Mitsubishi Heavy Industries (MHI) subsidiary Mitsubishi Shipbuilding has delivered its first FGSS (Fuel Gas Supply System) for dual fuel marine engines, which will be installed onboard the first LNG fuelled pure car carrier (PCC) built in Japan, currently under construction at Shin Kurushima Toyohashi Shipbuilding.

Mitsubishi Shipbuilding provided the shipyard with engineering services and technical support relating to gas handling for the ship. The FGSS is an LNG fuel gas supply system developed by Mitsubishi Shipbuilding using LNG and vaporised gas handling technology, developed through its experience on the construction of LNG carriers. The system has been verified for marine use backed by accumulated experience in marine engine manufacturers' test facilities. The system comprises LNG fuel tanks, LNG fuel gas supply units and control unit, delivered in modular format. which permits optimum design of the cargo space and helps reduce installation time. Operational safety is enhanced by tailoring the control system to meet individual operators' needs.

The FGSS is expected to contribute to the environmental performance of the ship, meeting the global SOx emission regulations and improving the energy efficiency (CO2 emissions per unit of transportation) of the ship by approximately 40%, which exceeds IMO EEDI Phase 3 requirements that will become effective in 2025. The ship is expected to reduce SOx by approximately 99% and NOx by approximately 86% over conventional HFO-fired engines. The ship has been adopted by Japan's Ministry of Environment and Ministry of Land, Infrastructure, Transport and Tourism as a model project to reduce CO2 emissions by using alternative fuel.

Converting oil-fired ships to burn LNG is one solution to conform to upcoming emission regulations. By providing the FGSS and related engineering services and technical support for newbuildings and conversions, Mitsubishi Shipbuilding will contribute to the economy for the ship owners and operators, increase the added value of the ships and reduce the environmental load that is increasing on a global scale.
