Client: Greenergy Terminals
Plymouth Tank Farm is one of the main fuel storage and distribution terminals in the Southwest. JGP have worked for Greenergy and the previous site owner Conoco Philips for an extended period providing various multi-disciplinary services.
The Tank Farm is located adjacent to the estuarine ‘Cattewater’, which is the deep-water channel that connects the River Plym to the Plymouth Sound. The tank farm is split into two sites, one next to the Cattewater and the other within the adjacent disused limestone quarry.
Both sites have been in industrial use from the early 1900’s and have historic contamination issues.
The tank farm is an upper tier COMAH (Control of Major Accident and Hazard) site. The tank farm has a storage capacity of approximately 40 million litres of product; which comprises bioethanol, biodiesel, petrol, diesel, kerosene and gas oil. Product is supplied by ship from loading arms at a local wharf and is distributed from the terminal by road tankers across the Southwest.
The terminal was purchased by Greenergy in 2008 and the infrastructure and tanks have been progressively upgraded since then to meet Health and Safety Executive and Environment Agency requirements post Buncefield.
JGP has carried out a variety of work involving structural, environmental and geotechnical engineering and project management for the terminal owners, including:
- Reviewed and updated Environmental Impact Assessment (EIA) for unified site;
- Reviewed and updated EIA in accordance with new Chemical and Downstream Oil Industries Forum (CDOIF) Guidelines;
