Decommissioning and site preparation works

Introduction

Following the cessation of oil and gas production (COP) at Liverpool Bay facilities in December 2024, we are now decommissioning and repurposing the existing infrastructure at the Point of Ayr (PoA) Terminal and surrounding colliery area to facilitate its integration into the Liverpool Bay Transport & Storage (T&S) infrastructure.

Decommissioning and site preparation works at the PoA Terminal and surrounding colliery area began in September 2025, with planning consent granted by Flintshire County Council (FCC) in May 2024 under the Town and Country Planning Act (TCPA) 1990 (as amended). These works will play a crucial role in preparing the PoA Terminal for future carbon dioxide (CO2) transportation and storage operations and ensuring it is ready for the equipment to transport and store CO₂ offshore to the Douglas Complex and three satellite platforms for permanent storage.

The work includes:

partially decommissioning the PoA facilities to enable CO₂ transportation and storage; and
housing new equipment to enable the filtering and compression of CO₂ before it is sent to the offshore pipeline, including PIGing facilities (please see our FAQs for further information on PIGing facilities), filters, compressors, a diesel system, a vent package, nitrogen generation, sub-stations, buildings and a warehouse.

Demolition layout

The PoA development includes the demolition of existing facilities that are either not required for this redevelopment or cannot be repurposed, along with the refurbishment of the remaining buildings to meet project needs.

To help visualise the scope of plant equipment removal, the skyline graphic below illustrates the planned changes to the site. Items highlighted in red are scheduled for removal, including the taller stacks and chimneys.
