An oil spill response company in the UK has partnered with an aviation organization to outfit two Boeing 727s with equipment to spray dispersant. Oil Spill Response Limited and 2Excel Aviation have developed and operationalized what they call the TERSUS dispersant delivery system that appears to use some of the same principles as the Modular Airborne FireFighting System (MAFFS) and the 747 SuperTanker. However it delivers the oil dispersant through spray bars, rather than doors in the belly.

The 727 has seven 2,200 liter (581-gallon) tanks, for a total of 15,400 liters (4,067 gallons), and a pumping system capable of delivering up to 1,200 liters (317 gallons) of oil spill dispersant per minute. It is likely that it uses compressed air to force the liquid out of the tanks.

Only 317 gallons per minute would not be effective if used to apply water or retardant on a vegetation fire.

The 727 works with a Cessna Navajo PA-31 surveillance aircraft to assess the extent of any oil spill and provide guidance to the larger aircraft.

The three aircraft are on standby ready to depart within four hours anywhere in the world.
