Decommissioning of Offshore Oil and Gas Installations and Pipelines

These Guidance Notes have been prepared to provide operators, licensees and contractors with guidance on the regulatory requirements for decommissioning offshore oil and gas installations and pipelines in accordance with international obligations and those set out in the Petroleum Act.

Description

These Guidance Notes have been prepared to provide operators, licensees and contractors with guidance on the regulatory requirements for decommissioning offshore oil and gas
installations and pipelines in accordance with international obligations and those set out in the Petroleum Act. They have been updated to reflect the knowledge and learning gained by regulators and industry, in planning, preparing and executing a decommissioning programme.

The Guidance Notes are largely unchanged from the 2009 version with the founding principles enshrined in the UKs commitment to OSPAR Decision 98/3 and its requirement that all installations should be completely removed unless a derogation is granted. However some of the decommissioning processes have been amended to provide greater clarity on requirements and what is expected of operators at the differing stages in decommissioning, alongside a flow diagram showing the different pathways that a project can take (Annex H).

Updated guidance on the environmental appraisal requirements for decommissioning is also provided (to follow).
