097 Tanker Ship Operation – Inert Gas System (IGS) Function Test | Safety & Maintenance Training

The Inert Gas System (IGS) function test is one of the most important safety checks carried out onboard tanker ships before cargo discharge operations. This video provides a step-by-step overview of how the IGS safety devices are tested in line with tanker operation manuals, international safety standards, and OCIMF/ICS recommendations. Viewers will learn how to test the response of the IGS to critical parameters, including: Scrubber cooling water pressure Inert gas temperature at fan outlet Control air supply pressure Electric power failure and alarms High drain water levels in scrubbers Deck seal water feed pressure and levels IG mainline pressure monitoring Oxygen concentration in inert gas Performing these tests ensures that the IGS can maintain a safe atmosphere inside cargo tanks, preventing the risk of fire or explosion during cargo discharge, stripping, or crude oil washing operations. This training resource is highly valuable for maritime students, cadets, and professional seafarers preparing for tanker operations, as well as for shipping companies emphasizing compliance with SOLAS, ISGOTT, and tanker safety manuals. 👉 If you find this video useful, don’t forget to like, comment, and subscribe to our channel for more tanker operation training materials.
