Offshore Chemical Notification Scheme (OCNS)

Photo: Oil Rig The Offshore Chemical Notification Scheme (OCNS) manages chemical use and discharge by the UK offshore petroleum industry. The scheme is regulated by the Department of Trade and Industry (DTI), using scientific and environmental advice from Cefas and the Fisheries Research Services (FRS).

The OCNS uses the OSPAR Harmonised Mandatory Control Scheme (HMCS) developed through the OSPAR Decision 2002/2 and its supporting Recommendations. This ranks chemical products according to Hazard Quotient (HQ), calculated using the CHARM (Chemical and Risk Management) model.

Within the OCNS website, further details can be obtained on the background and detail including the updated Ranked Product Listing and documents required for chemical certification. Contact the OCNS team.
