Question 176Safety & Environmental - QMED

The correct answer is D) all of the above. The reason this is the correct answer is that LNG carriers are required to have an approved gas detection system to monitor methane leaks in the cargo handling rooms, barrier spaces, and boiler burner supply piping. This requirement is specified in the regulations governing the design and operation of LNG carriers, which are based on international safety standards. The gas detection system is a critical safety feature to quickly identify any potential leaks of the flammable LNG cargo, allowing the crew to respond appropriately. The other answer choices are incorrect because they only specify a subset of the areas where gas detection is required, whereas the regulations mandate monitoring in all of these locations on an LNG carrier.
