Zone II Steam Generator (DNV2.7-2)

RentAir Offshore has launched single lift, fully compliant, DNV2.7-2 approved Zone II Steam Generators.

The DNV2.7-2 standard is being driven through the industry to enhance offshore equipment safety standards.

Whilst designing our Zone II Steam Generators we not only implemented extensive safety features to comply fully with the DNV2.7-2 global certification standard, but also maintained our leading industry small footprint and single lift strategy to ensure we minimise transportation costs and help our customers maximise deck space.

The new Zone II DNV 2.7-2 steam generators have been designed to include the fuel and water tank inside the DNV 2.7-1 offshore container, this means the compact design only requires one lift to deploy, minimising the risks involved in deployment and saving time.

The safety features comprise gas and fire detection, ignition prevention with no temperature greater than 200°C as well as external control panels providing enhanced safety for operating personnel.

Emergency shutdown facility is remote ensuring instant safe shutdown should methane, propane and H2S gas be detected or encountered.
