Challenges faced
Analysis showed that the fuel was heavily contaminated with water, colloid carbon, ashphaltine deposits and gums, resins and varnish crystals. Such was the level of particulate, it was not possible to assign an ISO cleanliness code because the samples were out of range.
Solutions delivered
WASP and Optimum Power Services (OPS) proposed replacing the legacy fuel polishing system with Diesel Defence DD90. The DD90 will reliably maintain the fuel, be autonomous in operation and could be effective on diesel that included up to 20% biodiesel.Alongside the DD90, WASP and OPS also installed vent TRAP filters to prevent dirt and moisture from entering the tank through open air vents.
