Two types of FPSO’s can be distinguished: conversions and new buildings. In case of a converted Crude Oil tanker, the existing flue gas installation may be used or refurbished. If the boiler is decommissioning or removed an independent Inert Gas Generator is installed. In both conversions and newbuildings; systems supplied are often equipped with dual fuel burners (capable of using natural gas or diesel oil as fuel). Further most FPSOs are fitted with a double system for redundancy purposes.

The requirements for Inert Gas Generation on board of FPSOs and FSOs can differ tremendously. The system execution may vary from a standard Inert Gas Generator for machinery space fitting; suitable for outdoors installation (in classified or non-classified area) up to complete packaged units.

Aalborg Industries Inert Gas Systems has developed several standards for the offshore industry, but at the same time is also able to offer custom-built plants according to customer specifications.
