Dear Capt. Lovely:

I am writing you to advise you of some significant cost savings we have been able to achieve on the NOAA ship MALCOLM BALDRIGE, formerly NOAA Ship RESEARCHER, as a result of using DFT #1500 "Hammerdown".

Since her commissioning 18 years ago, I am only the third Chief Engineer aboard the MALCOLM BALDRIGE. Her first Chief Engineer, Ted Ficken, began use of your product in January 1977 and after 3047 engine hours was able to document fuel savings (including treatments costs) of $19,956 at a cost of fuel of $0.402/gal. Since then, the product has been used continuously. In 1985 17,000 hours after the last engine overhaul in 1981, Chief Bob Mattos inspected the engines and decided no overhaul was needed for several more years. After 27,000 engine hours, I decided to reinspect the engines and several of the main and connecting rod bearings. We found an absence of carbon build-up on the top sides of the piston wall above the top ring groove, on the 1 1\2 inch tapered section of the upper liner walls, on the fire side of the cylinder heads, in the valve chambers, and on the injector nozzles. We also found no significant wear on any of the parts. This verified the results predicted by the lube oil analyses, which I gave you copies of earlier. Mr. Ray Costello, the ALCO technical representative, noted that the lack of carbon build-up is very unusual, particularly for engines such as ours which most of the time do not operate under full load. Again we have decided that the engine's condition warrant deferring the major overhaul for at least another year. There is little doubt that our continued use of DFT #1500 "Hammerdown" was instrumental in the increased engine life and resultant maintenance costs.

Your product also was responsible for savings in not having to clean or repair any of our 25 fuel tanks. The MALCOLM BALDRIGE normally carries as much as 185,000 gallons diesel. Fuel remains in the tanks an average of 2 to 4 months. When the tanks were opened for ABS inspection in January 1987, all were found to be in excellent condition with almost no sludge. This duplicated the inspection made five years earlier. Each time we were spared the expenses of tank desludging and cleaning.

Based on the records and comments of my predecessors, Chiefs Ficken and Mattos, as well as my own experience, I estimate that continuous use of DFT #1500 "Hammerdown" over the past 12 years has saved NOAA at least $50,000 per year, or in excess of $600,000, as a result of the improved engine performance and life and reduced operating and maintenance costs. I commend you for producing such an excellent fuel treatment

Respectfully,

Mark M. Marriner
Chief Engineer
NOAA Ship MALCOLM BALDRIGE
