We recently received a call from a frozen food distribution centre near Bristol following issues with their 22,000 litre Diesel underground storage tank (UST) used to supply their fleet of distribution lorries.
As the storage of fuels was not the distribution centres main source of business and was just an asset that the company used to run its fleet; we were called in to assess what had occurred.
The maintenance of fuel and its storage facilities are our bread and butter and following the call we mobilised to site to test the tank using our Tanknology Vacutect tank testing system that applies a precision vacuum to the tank and associated lines testing for weak points.
Once the tank had been tested it was apparent that the fill riser was at fault, this was repaired on site and the tank re-tested and passed. However, it was advised by our Senior VacuTect Engineer that the tank undergo an internal tank inspection and de-sludge service using our Tanknology Petroscope camera system.
Our Petroscope camera offers the only solution within the UK to thoroughly maintain the internal space of a storage tank using remote technology to inspect and de-sludge the internal space removing the need for the high-risk operation of manned entry. Read more about it here.
Once on site our Petroscope team set up and carried out the following scope of works:
Following the inspection the client is issued full reports for both the VacuTect test and Petroscope inspection with a copy of the inspections and cleaning.
Our footage of the internal space of the UST enables us to provide digital imagery of a quality where professional analysis by a corrosion engineer is possible should it be required.

To do the job quickly does require a lot of equipment but we are used to squeezing it into small places! We use barrier fencing to keep the public away from the danger our work poses.
The camera truck has two screens one for the operator to view what the camera sees and from which the operator records the inspection and a second that enables the tank cleaner to steer his cleaning hoses to where the dirt and sludge is located in the tank.
The tanker cleaner, stood adjacent to the tripod who is supporting the camera in the tank is looking at the TV screen so that he can ‘steer’ his hoses to clean the tank.
