Offshore Degreasing & Cleaning

Offshore Degreasing & Cleaning

The Offshore Chemical Notification Scheme (OCNS) manages chemical use and discharge by the UK and Netherlands offshore petroleum industries and applies to all chemicals which are used in exploration, exploitation and offshore processing on the UK Continental Shelf.

The scheme applies to those “operational” chemicals and products which through their mode of use are expected in some proportion to be discharged, eg. rigwashes and hydraulic fluids.

Products are listed in six colour bands, according to Hazard Quotient, with Gold being awarded for the lowest hazard and purple being the highest. For further information, visit the CEFAS website here.
