Nigel Plumb and Kathy Early are this month celebrating the 50th anniversary of the foundation, by their father David Plumb, of the company that would later become DP Fuel Tank Services (DP FTS), of which they are both directors. Nigel Plumb said: "Over the years, the size of the tanks we work on has expanded. We have used the skills we gained working on service areas to clean and/or remove tanks up to five million litres, carrying out work for power companies and the MOD in locations as far away as the Falklands."
One of its diversifications is offering ultrasound testing, which detects whether tanks are thinning in a particular spot, which is likely to lead to a leak in the future. Where leaks have occurred it can deal with decontamination and tank relining, or even site decommissioning and demolition.
Plumb added: "Evolution, of course, never stops, and now we are looking at ways of adapting our services still further to meet the constantly changing needs of the industry."
