Existing OGS 3.1 systems are still supported and eligible for spares and services.
This product is replaced by OGS 3.2.
The OGS 3.1 is our top of the range gas sampling system and typically used in the oil and gas offshore industry. The system contains a monitoring cabinet and a detector cabinet, that both can be installed in EX areas. The system’s scalability enables us to design the ideal solution for the individual operational challenges on e.g. FPSOs, FLNG or drilling rigs. OGS 3.1 meets the requirement set out by IMO and the different classification societies.
Features
Standard
