“A Navy ship crash in 1995 which resulted in a explosive gasoline fire spawned a DoD directive for all gasoline powered engines and gasoline fuel tanks be removed from Naval ships by 2010,” Tony said. The mandate called for engines to be developed to operate on fuels that meet the following criteria:
- 1) Improve ship safety by minimizing fire hazards
- More economical and more efficient
- Readily available as a single battle space fuel
Tony said every ship carries JP 5 fuel. Ports have JP8 and Commercial Jet A available. The common denominator with all three fuels is availability. “An unlimited fuel supply enhances our ability to protect assets on the water,” said Tony. It also greatly increases crew safety. Tony said, “There was another ship fire since the 2010 DoD mandate. The fact that the ship only had JP aviation fuels on board provided the crew enough time to react and save the ship in a safe and efficient manner,” said Tony.
The OptiMax JP has been a resounding success. Hundreds of engines were deployed on Army high speed combat craft during the Iraq war. In another program, the OptiMax JP powerhead was mounted to a Mercury Sport Jet pump, which is the propulsion for Sea Fox USVs (unmanned surface vessels). “Sea Foxes are currently in use in the Iranian theater. These remote controlled vessels are deployed to protect and escort U.S. war ships in International waters,” said Tony. The Army uses OptiMax JPs on their riverine combat craft and the Navy uses them on their 8 meter target boats.
Structural Composites, Inc., is one private sector company currently running JPs. They have developed a 8.5 meter composite rib for the Navy. I called Structural Composites rep Scott Lewit to get some feedback regarding their hull and OptiMax JP experience. Scott said their rib is unique in the manner in which it is constructed. The use of space-age composite materials resulted in a 40% weight savings to comparable sized hulls.
