Notification of offshore substances or materials

Special rules apply to the registration of substances or materials that are used in the offshore industry. Chemical substances or materials that are used in the offshore industry are covered by the OSPAR guidelines and must be notified or re-notified in the Product Registry in accordance with the OSPAR guidelines before use. OSPAR is a commission that aims to protect and conserve marine animals and plants.

How to notify

Registration of offshore chemicals must be submitted via a special registration form from OSPAR called an HOCNF form (Harmonised Offshore Chemical Notification Format). The form is available on the CEFAS website

The form is filled out and uploaded along with the electronic notification which must be done to the Product Registry via OnlineAt. When registering offshore chemicals, you must include the exact composition of the offshore substance or material as well as its ecotoxicological properties in accordance with the OSPAR guidelines. 

When the notification has been filled out and submitted the Product Registry will automatically provide you with a PR number that confirms your registration of an offshore substance or material. 

Note that substances or materials for offshore use must be re-notified in the Product Registry every three years.

What is the information used for?

Information regarding the composition of the substance or material as well as its ecotoxicological properties is registered in the Product Registry. The Environmental Protection Agency uses this information when an operator applies for a discharge permit for offshore substances or materials.
