Floating Roof Tanks

First strike fire extinguishing system for floating roof tanks

The National Oil Company in Qatar stores crude in several offshore terminals, predominately in large capacity floating roof tanks.

The particular concern was the rimseal area between the floating roof and the tank wall – they knew this is where 90% of rimseal fires start. Fixed foam systems were in place, but as with so many fixed systems protecting large capacity tanks the systems had to be manually operated. Their concern was that the distance from the Tank Farm to the Control Centre was such that any fire could burn for some time before it was physically detected.

Our engineers looked at all the options, including gaseous systems, and concluded that foam provided the best solution because of its ability to provide post fire security through a slow draining foam blanket sitting in the seal area of the fire.

The unique combination of Angus Engineering, the manufacturing skills of our team at Bentham in the UK, and our historic and well proven technology with foam concentrates made the product possible.
