## When to use it

Use when an offshore petroleum titleholder is planning the end of a facility or a well in NOPSEMA's jurisdiction. It records the principles on the decommissioning page. It does not draft an environment plan.

## Used for these tasks

- [Map decommissioning obligations and financial-assurance gaps](https://ailawframework.com/practice/energy-resources-and-mining/map-decommissioning-obligations-and-financial-assurance-gaps.md)
- [Map offshore or onshore licence conditions and safety-case obligations](https://ailawframework.com/practice/energy-resources-and-mining/map-offshore-or-onshore-licence-conditions-and-safety-case-obligations.md)

## How AI may be used

AI may list infrastructure against the title expiry and the principles on the NOPSEMA page; the lawyer decides whether an environment plan and a removal plan meet the current regulations.

**AI may:**

- Build a table of infrastructure, title, and title-end date from documents already on the file
- Mark whether full removal or an alternative is proposed
- Record that the NOPTA guidelines are the document the page points to and have not yet been read

**AI must not:**

- Must not conclude that an alternative to full removal delivers an equal or better environmental outcome
- Must not draft an environment plan, a safety case, or a well-operations plan
- Must not state a financial-assurance amount

**The lawyer checks:**

- Each item of infrastructure has a titleholder and a plan to finish decommissioning before the title ends
- Any alternative to full removal is assessed against equal or better environmental outcomes and against the OPGGS Act and regulations, including well integrity and safety
- The NOPTA Offshore Petroleum: Decommissioning Guidelines, which the page cites, are read before the plan is settled
- Permissioning documents are identified for NOPSEMA assessment rather than assumed from this checklist
