Oil Pollution Emergency Plans (OPEPs)
By combining preparedness with operational spill response expertise, OSRL can help operators develop Oil Pollution Emergency Plans (OPEPs) that are compliant, practical and response ready in the event of an oil spill incident within the UK Continental Shelf (UKCS).
What is an OPEP?
An OPEP is a site or activity specific document that describes how an operator will respond to an oil pollution incident within the UKCS.
It is the output of the oil spill preparedness planning process, establishing a robust tiered preparedness and response framework. Previous experience demonstrates that by having a well-developed, approved, implemented and exercised OPEP in place, it allows an effective response to be initiated which aims to reduce the potential impact of an oil spill incident on people, the environment, assets, and business reputation.
This includes having suitably trained personnel, an adequate response capability, well executed and exercised scenario planning, and relevant oil spill preparedness plans in place.
Why is an OPEP required?
An OPEP is required for any offshore oil and gas activity on the UKCS that presents a risk of oil pollution, including:
- Offshore oil and gas installations (fixed and mobile)
- Wells (exploration, appraisal, development, production and abandonment)
- Pipelines and subsea infrastructure
- Hydrocarbon storage and inventories
- Associated offshore operations with spill potential
An approved OPEP is required under the OPRC Regulations[1] and must be prepared and submitted in accordance with the Guidance Notes for Preparing OPEPs[2] and approved by the Offshore Petroleum Regulator for Environment and Decommissioning (OPRED) before operations commence.
What type of OPEP do I need?
There are several approaches an operator can adopt when preparing an OPEP and various types of plans can be developed based on operational needs. The type of OPEP required will be determined by the type of operation being undertaken, but it must be developed in full compliance with the OPRC Regulations[1] and the Guidance Notes for Preparing OPEPs[2].
| Type of OPEP | Description | Response Arrangements Covered |
|---|---|---|
| Onshore OPEP | Includes Tier 2 and 3 response arrangements and specific operational information to support an onshore response team. It can be supplemented by a Production Installation/Field OPEP or a Temporary Operations OPEP (TOOPEP). | Tier 2 & 3 |
| Production Installation/Field OPEP (Offshore OPEP) | Details Tier 1 response arrangements for production installations or fields, including operational information to aid offshore response teams. | Tier 1 |
| Consolidated OPEP | Combines the Onshore and Production Installation/Field OPEP requirements into one comprehensive document covering all response levels. | Tier 1, 2 & 3 |
| Temporary Operations OPEP (TOOPEP) | Addresses Tier 1 response arrangements for temporary offshore operations, such as drilling or intervention activities, and aligns with Onshore OPEP requirements. | Tier 1 |
| Consolidated TOOPEP | Integrates Onshore OPEP and TOOPEP requirements into a single document, covering all response levels for temporary operations. | Tier 1, 2 & 3 |
| Communication and Interface Plan (CIP) | Links multiple OPEPs for specific operational activities and provides additional relevant information to ensure effective coordination. | Varies (links multiple OPEPs) |
| Pipeline OPEP | Developed for standalone pipeline operations not covered under other OPEPs, including all relevant response arrangements specific to the pipeline. | Tier 1, 2 & 3 |
What will be in my OPEP?
The OPEP should be developed considering the company’s organisational response structure, oil spill risk profile, Tier 1, 2 and 3 response arrangements, and the overall response techniques available to the company. The OPEP should be written to interface with existing company emergency framework and any other relevant OPEPs.
An OPEP typically includes certain key elements, such as:
- Response checklists and guidance for management / response personnel
- Organisational response structure
- Oil spill response techniques
- Tier 1, 2 and 3 response arrangements and capability
- Interfacing arrangements and requirements
- Operational overview
- Well, hydrocarbon inventories and pipeline data
- Oil spill modelling
- Environmental and socioeconomic sensitivities
- Primacy arrangements
How OSRL supports OPEP preparedness
An effective OPEP provides clarity during the early stages of an incident when decisions need to be made quickly and confidence in response arrangements is critical.
OSRL supports operators across the full OPEP lifecycle, from development, review and approval through to response integration and exercising.
OPEP development
OSRL works with operators to develop OPEPs that are compliant, proportionate, and operationally credible. Worst case oil spill modelling will be undertaken and included within the OPEP that is relevant to the operational risk.
OSRL will then support operators through the OPEP development and approval process, helping ensure clarity, consistency, and regulatory alignment.
Response integration
As a Tier 2 and Tier 3 response provider, OSRL helps ensure that OPEPs clearly describe how all relevant response resources will be accessed, mobilised, and integrated into the operators response structure.
Exercises and validation
OSRL designs and delivers exercises that test plans under realistic conditions, helping teams build confidence, identify gaps, and demonstrate preparedness to regulators.
Get support with your OPEP
Whether you are developing a new OPEP, reviewing an existing plan, or looking to strengthen your preparedness through exercising, OSRL can help.
