For marine four-stroke dual fuel engines, the approval is for a liquefied natural gas (LNG) fuel gas supply system (FGSS). The approval was confirmed today during a presentation ceremony at the headquarters of Mitsubishi Shipbuilding in Yokohama.

The LNG fuel tank, gas supply unit, control systems and other related equipment are part of the FGSS. The system was primarily designed for installation on coastal ferries and small to medium-sized cargo ships.

"This new system has received BV’s approval in principle recognizing that Mitsubishi Shipbuilding has clearly demonstrated that the new system meets our class rules and standards for gas safety and regulatory compliance. I congratulate Mitsubishi Shipbuilding – it is their deep experience and knowledge, acquired through decades of LNG carrier construction and technical development, that have enabled them to develop this innovative new system," said Claude Maillot, Bureau Veritas Senior Vice President, North Asia.

The FGSS will use vacuum-insulated storage tanks of a small size with a double shell structure that guarantees high heat insulation and enables the tank's outer cylinder to stay at normal temperatures as well. This simplifies the specifications for the tank's support system and reduces installation work.
