If you are a permit operator of a lower-tier petroleum production installation you must have a Major Accident Prevention Policy (MAPP). If you are a permit operator or drilling contractor of any other type of installation, you must have an accepted safety case.

We have produced guidance to explain the requirements for MAPPs and safety cases including how to prepare and submit a safety case.

These guidelines cover Parts 3 and 4 of the Health and Safety at Work (Petroleum Exploration and Extraction) Regulations 2016(external link) that apply to permit operators of all installations and drilling contractors of non-production installations.

While this guidance has not been updated to reflect current work health and safety legislation (the Health and Safety at Work Act 2015 and regulations), it may still contain relevant information and practices to keep workers and others healthy and safe.

Please read this guidance in conjunction with all relevant industry standards that apply to you as a PCBU. This guidance will be progressively reviewed and either updated, replaced with other guidance, or revoked.
