Bureau Veritas approves Mitsubishi’s LNG fuel system

Classification society Bureau Veritas has approves Mitsubishi Shipbuilding’s new LNG fuel gas supply system.

Mitsubishi Shipbuilding, a part of Mitsubishi Heavy Industries (MHI), received the approval in principle (AiP) for a liquefied natural gas 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 classification society said in its statement.

The system was developed mainly to be installed on coastal ferries and small to mid-sized cargo ships.

The FGSS will use small size ‘vacuum-insulated’ type containment tanks with a double shell structure that ensures high heat insulation and also allows the external cylinder of the tank to remain at normal temperatures. This simplifies the support structure requirements for the tank and reduces installation work.

Furthermore, the Tank Connection Space is also designed to reduce space, operational, and maintenance requirements.

Claude Maillot, Bureau Veritas senior vice president, North Asia said, “Innovations like these are helping drive the industry towards better environmental and operational performance – while reducing risk.”
