We (Esso Petroleum Company, Limited) launched our Southampton to London Pipeline Project late in 2017. The project proposes to replace 90km of our 105km aviation fuel pipeline that runs from our Fawley Refinery near Southampton, to our West London Terminal storage facility in Hounslow.

To date we have completed three public consultations on our project. Feedback from the 1,300 people who have taken part in the consultations, plus our ongoing meetings and conversations with local organisations and landowners, has helped us to refine the pipeline route.

We also listened to feedback about the 20 sub-options that were presented within the preferred route consultation in autumn 2018 alongside technical information, and this helped the project team to select the majority of sub-options to progress. Click here for details about the sub-option selection.

We have closed our third consultation which sought views on design refinements – those refinements that may have different potential impacts to our previous proposals for landowners, the environment or communities.

The consultation ran from 21 January 2019 to 23:59 19 February 2019.

A final route of the replacement pipeline will be part of our application for development consent, which we intend to submit in spring 2019.

Project Commitments

When we install the replacement pipeline, we commit to:

Protect habitats by using a 10m working width when crossing boundaries between fields where there are hedgerows, trees or watercourses.

Avoid all areas of existing classified Ancient Woodland.

Reduce disruption to travel by using trenchless installation techniques for crossing trunk roads, motorways and railways.

Include remotely operated valves to enable sections of the pipeline to be isolated, if necessary.

Ensure that the principles of safe design have been incorporated into the design of the pipeline, as per Esso’s design standards for fuel pipelines, relevant industry codes of practice, and the requirements of the Pipelines Safety Regulations 1996.

Reduce impacts on habitats and soil quality by typically using a standard working width of 30m for open cut trench installation in rural areas.

Protect waterways that are over 30m wide by using trenchless crossings.

Install ‘water stops’ to reduce the risk of underground water impacting on the materials that support the pipe.

Avoid installation in existing Source Protection Zone 1 (SPZ 1) areas to reduce impacts on sources of drinking water.

Monitor the operation of the pipeline 24 hours a day to detect any changes and remotely shut down the pipeline if needed.
