Decommissioning—International Law and UK Government Policy
Practice Note

This Practice Note provides an overview to the UK government policy on decommissioning in the UK, the process for permanently removing installations and infrastructure from the seabed or securing wells. Although the legislation that defines responsibility for decommissioning programmes and execution of such programmes lies within domestic legislation, the UK’s policy in respect of decommissioning programmes is heavily influenced by international law. The Convention for the Protection of the Marine Environment of the North-East Atlantic 1992 (OSPAR) plays a significant role in UK policy, in particular Decision 98/3 of that convention. The founding principle is that a clear sea-bed should be left though there are certain exceptions to this and derogations may be granted from time to time by the UK government.

Decommissioning—legislative background
Practice Note

This Practice Note provides an overview to the legislative background to oil and gas decommissioning on the United Kingdom Continental Shelf (UKCS), the process for permanently removing installations and infrastructure from the seabed or securing wells. The primary legislation is contained in Part IV of the Petroleum Act 1998. However, legislation (and policy) is constrained by the international conventions to which the UK is a signatory. The founding principle is that a clear sea-bed should be left, though there are certain exceptions to this and derogations may be granted from time to time by the UK government.
