Conrie

Project Overview

The Conrie oil project is part of a larger decommissioning program that includes several fields: Conrie, Don South West, West Don, and Ythan. These fields are located within Blocks 211/13b and 211/18a in the North Sea.

Field Location and Layout

• The fields are situated in the North Sea, with the Conrie field being one of the specific areas targeted for decommissioning.
• The project involves the decommissioning of various installations and pipeline infrastructure associated with these fields.

Decommissioning Program

• The decommissioning program is divided into phases. Phase 1 involves the removal of the Northern Producer Floating Production Facility, associated riser systems, and clearance of the 500m safety zone. Phase 2, which is the focus here, involves the decommissioning of the Conrie, Don South West, West Don, and Ythan installations along with the remaining pipeline infrastructure.

Infrastructure and Assets

• The project includes the decommissioning of several pipelines, including:
  • An 8-inch pipeline (PL2572) that transported processed oil from the Conrie, Don South West, and Ythan fields to the Northern Producer.
  • A 3-inch pipeline (PL2573) that imported processed gas from the Northern Producer.
  • Other pipelines such as PL2578, PL2579, and PL4555, which were used for various purposes including gas import and piggybacking.

Environmental and Regulatory Considerations

• The decommissioning program must comply with national and international regulations, including those set by the UK's Offshore Petroleum Regulator for Environment and Decommissioning (OPRED).
• Environmental sensitivities and potential impacts are assessed, and management strategies are put in place to mitigate these effects.

Stakeholder Consultations

• The decommissioning program involves public, stakeholder, and regulatory consultations to ensure that all parties are informed and their concerns are addressed.

Project Management and Timeline

• The decommissioning program is managed under a strict project management framework, with verification processes in place.
• The schedule for the decommissioning activities is planned over a five-year period, set to begin in Q2 2025.

Removal and Disposal Methods

• The decommissioning involves the removal of subsea facilities, stabilization features, and pipelines.
• Specific methods for removal and disposal of these assets are detailed in the decommissioning program, including waste stream management methods.

Industrial Implications

• The decommissioning has industrial implications, including the impact on local industries and the workforce involved in the oil and gas sector.
• The project requires careful planning to ensure minimal disruption and compliance with industrial regulations.

By considering these aspects, the Conrie oil project's decommissioning can be managed effectively, ensuring compliance with regulatory requirements, minimizing environmental impact, and addressing the needs of all stakeholders involved.
