Purpose
The Fixed gas sampling system is dedicated to the Gas Control in all Tanks, Void Spaces, Pump room or Houses adjacent to Cargo Storage Tanks and Handling Systems. In order to detect any Gas Concentration level over programmable limits and to monitor visible and audible alarms consequently, these areas are controlled by the suction process sampling on one or more common sensor(s) as well as by individual local sensors.
This system complies with ISGOTT regulation chap. 7.8 and 8.2.
