ME-GI Gas Supply Auxiliary Systems
The ME-GI gas supply auxiliary systems include:
• leakage detection and ventilation system, which
ventilates the outer pipe of the doublewall pip-
ing completely and incorporates leakages de-
tection
• inert gas system, which enables purging of the
fuel gas system on the engine and the fuel gas
supply system with inert gas
• gas return system (optional), receiving fuel gas
returned from the engine when gas pipes are
being depressurised.
