The Inert Gas System, IGS, course is designed for seafarers working on oil and chemical tankers, offshore units, or terminals whose duties involve cargo operations where an inert gas system is used to control the atmosphere in cargo tanks. The course provides practical and operational knowledge for the safe use of IGS, helping learners understand its purpose, limitations, and role in preventing fire, explosion, and other hazardous situations on board. It covers both the technical side and the safety framework behind tanker operations, including relevant principles from STCW, SOLAS, the FSS Code, the ISM Code, and industry guidance related to tanker cargo safety.
During the course, you will learn how the inert gas system works, why it is used, and which operational limitations must be considered during shipboard use. The program teaches you to identify hazards during cargo operations, including purging, gas-freeing, tank cleaning, and gas replacement sequences, while also building your understanding of the main system components, oxygen and pressure monitoring, alarm interpretation, and safe operating procedures. Special attention is given to emergency response, abnormal operating conditions, and the correct actions to take when equipment fails or system parameters move outside safe limits
After completing the course, the trainee undergoes a final knowledge assessment and receives an Inert Gas System course certificate upon successful completion. On maritime training platforms, this course is presented as a dedicated certification program for personnel involved in tanker operations, and the certificate confirms completion of the training in this subject area. The learning process is usually structured into training modules, followed by final evaluation, so the certificate reflects both course participation and successful completion of the required assessment.
Course Reviews
Very well-structured course. I finally understood the full picture of how the IGS works — from the gas generators to the deck seal and pressure/vacuum valves. The module on emergency responses was especially valuable.
Clear and practical content on inert gas operations. Covers exactly what you need to know for safe tanker cargo work: oxygen readings, alarm responses, purging sequences. I recommend it to anyone working on oil tankers.
The course gave me a solid understanding of IGS components and the logic behind inerting, purging and gas-freeing. Good balance between theory and practical procedures. Passed the test on the first try.
Comprehensive material on SOLAS and FSS Code requirements. The section on backflow prevention and the deck water seal was new to me and very useful. Would appreciate a few more interactive exercises.
