Case study - Decommissioning

Fuel terminal

The challenge

The client, a large forecourt operator, approached us about the demolition of one of their assets.

The main challenge was ensuring the site was safe to work in which required the removal of any remaining fuel from site.

As the site was situated on a waterway, we also needed to ensure no contamination occurred.

Due to the area being hazardous, CompEx electricians ensured that the site was safe, and free of live cables or other hazards.

We also had a number of operators with confined space certification to carry out the tank cleaning.

Our Response

Due to the area being hazardous, CompEx electricians first ensured that the site was safe, and free of live cables or other hazards. The first phase was to remove all the residual fuel from the site, and carry out all the tank cleaning with confined space certified operators.

Each tank had different fuels, including petrol, diesel and kerosene, and were capable of holding around five million litres of product. We drained all the tanks, took the fuel off site and then did a man-entry clean on each tank to ensure they were gas-free and ready for demolition.

The second phase was to dismantle the pipework and structures.  There was still about 20,000 litres of fuel in the pipes that needed to be removed before this could happen. In order to do this, all the valves were dropped and each area was sucked out, once the fuel was removed, we used gas monitoring wands to ensure there was no gas left inside. This was done a few weeks before the demolition started to allow any residual vapours to vent away.

In phase three we broke up the concrete and excavated the site. We also undertook ground testing and sampling to make sure there was no contamination.

The fourth phase was to remove all the pipe work from under the jetty, grade the site, remove the remaining buildings, carry out final soil testing before handing the site back to the client.

The Outcome

The project was completed on time and on budget, safely and compliantly.

We removed and disposed of all the waste liquid fuel, and managed the demolition of the physical assets.

Our teams of highly qualified consultants and ecologists supported in the remediation of any contamination in the land, allowing it to be handed over primed and ready for redevelopment.

What the client said

"The decommissioning of the fuel terminal is one of the most significant projects we have undertaken. Adler and Allan were selected based on their excellent safety record and historic quality of service delivery. Their ability to provide in-house expertise across multiple disciplines was reflected in their highly competitive costs."

The Adler and Allan Difference

Adler and Allan has been a one stop shop from arranging the risk assessments and method statements at the start, right through to handing the land back to the client at the end of the project.

Our in-house expertise has seen us deliver services from gas freeing and removal of fuel from the site, to CompEx electricians removing the electricals in hazardous areas, teams of highly qualified consultants and ecologists supporting in the remediation of contaminated land, and ultimately demolition.

We have a wide range of assets at our disposal from vacuum and fuel tankers for fuel removal, and demolition equipment for the breakdown of the tanks.

We also have the infrastructure to get our people wherever they are needed, with depots and equipment nationwide.
