Streamlining the regulatory journey for offshore oil and gas decommissioning

Offshore Dismantling and Removal

Some or all dismantling of the asset may take place at the site of operation.  Depending on the regulatory regime involved, responsibility for compliance may shift from the asset owner/operator to the contractor undertaking dismantling or removal. If you have responsibility for removing and returning material or waste to shore for reuse, repurposing, recycling or disposal, you can find further information in the section on Onshore Dismantling and Disposal.

OGA

Under the Pipeline Safety Regulations, no modification to a pipeline, including its decommissioning and/or removal, can be carried out without a Pipeline Works Authorisation (PWA) or variation approved by OGA.

HSE

In order to dismantle and remove an offshore installation, a dismantlement safety case must be submitted and accepted by OSDR as the competent authority.  The case must fully detail the intended dismantlement and removal method and provide timescales for the operations to be undertaken.

As with a material change, OSDR assessment will follow the same framework and process as a full safety case.

Specific topic specialist guidance is currently being developed with regards what would be expected in a dismantlement safety case.

The specific requirements needed to address pipeline aspects in an offshore safety case are given in the pipelines safety case assessment template.

SEPA

SEPA directly regulates offshore dismantling and removal activities where (I) the waste or redundant items contain naturally-occurring radioactive material (NORM) or (ii) the waste is being shipped abroad for recovery or disposal under the Transfrontier Shipment Regulations. Operators also need to consider the future management of any redundant items, and whether they need to be treated as waste if returned to shore.

Exporting Recyclable Waste for Recovery in non-OECD Countries  This guidance provides information to help businesses determine the procedures to be followed when exporting 'green list' waste. It gives details of the different procedures and controls which apply to exporting to EU/OECD countries, and to non-OECD countries, and information on determining whether your waste consignment meets the criteria for export as 'green list' waste. The guidance applies across the United Kingdom.

 Moving Notified Waste Between Countries  This guidance provides information on moving waste to and from the United Kingdom (UK), where that type of waste is subject to notification and consent procedures.  It details how to apply for permission, the criteria to be met before the shipment will be approved, other steps required before the waste can be shipped, and what actions should be taken if notified waste is imported to the UK from another country. This guidance applies throughout the United Kingdom.

Management of End-of-life Smoke Detectors  Ionising smoke detectors are a commonly used safety feature on offshore installations and may still be present on an offshore installation when it is sent for decommissioning onshore. This guidance provides information on managing end-of-life smoke detectors in a way which meets the requirements of Waste Electrical and Electronic Equipment (WEEE) Regulations 2013 and the Environmental Authorisations (Scotland) Regulations 2018 (EASR).

Guidance on Reuse Activities and Waste Regulations  This guidance explains what SEPA means by 'reuse' of products or components of products. It guidance on determining whether a product destined for reuse is considered waste or non-waste, and thus whether waste legislation applies to that product or component.
