BV GRANTS AiP FOR MITSUBISHI LNG FUEL GAS SUPPLY SYSTEM

BV GRANTS AiP FOR MITSUBISHI LNG FUEL GAS SUPPLY SYSTEM

Friday, October 23, 2020 

Mitsubishi Shipbuilding, a part of Mitsubishi Heavy Industries (MHI), has been granted Approval in Principle (AiP) from the French Classification Society, Bureau Veritas (BV), for its liquefied natural gas (LNG) fuel gas supply system (FGSS) for marine four-stroke dual fuel engines.

The FGSS comprises an LNG fuel tank, gas supply unit, control systems and other relevant equipment.  The FGSS was developed principally for coastal ferries and small to mid-sized cargo ships, based on MHI's experience of LNG carriers and knowledge accumulated through FGSS products for large ships. The small size vacuum-insulated type tanks have a double shell structure that ensures high heat insulation and allows the external cylinder of the tank to be at normal temperature, which consequently simplifies the support structure of the tank and reduces installation work. Further, the Tank Connection Space is designed to save space while giving consideration to operation and maintenance.

Mitsubishi Shipbuilding delivered a FGSS in 2019 to Japan’s first LNG-fuelled car carrier, currently being built at Shin Kurushima Toyohashi Shipbuilding, and has one more order for a ship currently under construction. Those large tanks with insulation coatings are designed to be the best fit for the installation in large vessels.
