What people have said about Fleury

  • “Fleury Engineering provided an innovative solution for a gas turbine oil flushing system using an external oil filter along with the permeant oil filtration system of the turbine to allow us to carry out the flushing to the high cleanliness standard required in a much quicker timescale than had ever been achieved on any power project previously. This gave us 14 days back to our commissioning schedule which in any project is huge bonus.”

    Gerry Taylor - Alder Offshore, Delivery Manager
  • “The naval service today is very operationally focused and a key part of that is having the correct fuel, and maintaining it to the correct quality and spec. What sets Fleury Engineering apart is the customer focused solutions. I find that when I employ Fleury Engineering to fault find or develop solutions for the naval service, that I don’t have to give it a second thought. I can just give the job to Fleury and the job is done.”
