Wärtsilä Offshore Inert Gas Packages

Our inert gas generator system ensures the correct atmosphere in the cargo tanks and pipes to minimize the risk of explosion onboard FPSOs and FSOs.

Based on more than 20 years of experience in the design and manufacturing of inert gas generator systems, the Wärtsilä Moss systems are known for their high inert gas quality and overall reliability.

High efficiency, low maintenance costs, and easy and safe operation, in combination with minimum space requirements, are important features of the unique design. The Wärtsilä Moss systems can be installed on new builds or as retrofits for existing vessels.

    What is Inert Gas?

    Inert Gas is a gas or a mixture of gases, such as flue gas, containing insufficient oxygen to support the combustion of hydrocarbons. An Inert condition is a condition in which the oxygen content throughout the atmosphere of a tank has been reduced to 8% or less by volume.
