In the case of a leak in the containment system of a ship carrying dangerous liquid cargo at a temperature below –55°, there is no practical way to stop it while the ship is loaded. As a consequence, monitoring containment systems for such a vessel are of utmost importance since a leak in containment system is not only a potential fire or explosive hazard, it is also a potential danger for the ship's structure which could be locally subject to brittle fracture.

For this purpose, IMO gas code requires, among other safety means, all ships designed for transportation of flammable or explosive products at temperatures below - 55° (which is the case for LNG ships) to have specific permanent instrumentation fitted for monitoring temperature and detecting gas leakages.

This instrumentation should give reading at regular intervals (up to 30 minutes maximum for gas detection) and send warning when preset levels are exceeded (the lowest temperature for which the hull steel is suitable, when monitoring temperature, or 30% of lower flammable limit for gas detection for example).
