Shell Retail Fuelling, Eastfield, UK

Bespoke Fibrelite double tank chambers enable continued use of split-compartment tanks at Shell Eastfield

Project overview

When surveying Shell Eastfield as part of a refurbishment program programme for the site, our UK site team discovered that two of the tanks had double manways that were too close together to install traditional tank sumps and required a bespoke solution work for a successful install.

Problem

As part of their refurbishment program programme, Shell specified watertight tank chamber, but two of the tanks had split compartments which meant they had two tank upstands. This meant that they were too close together to install traditional tank chambers/sumps.

Solution

We fabricated two S12SQ Fibrelite chambers and corbels together, forming a bespoke solution which would fit the existing double manways.

After installation of the complete watertight chamber systems, our UK site team performed a vacuum test to ensure that the Fibrelite systems were liquid tight.
