COMPANY PROFILE

Getting Tke Bugs Out

A Deep Submergence Vehicle

Support Ship, a utility vessel, and an offshore drilling rig have solved their diesel bug problems by fitting special magnetic microbial decont- amination units in their fuel sys- tems. These unique devices,

De-Bug™ Fuel Decontamination

Units, eliminate diesel microbes and associated problems in a clean, safe, environmentally friendly manner without toxic biocides.

Developed 14 years ago in New

Zealand by De-Bug Worldwide

Limited, a leader in magnetic decontamination, the units are marketed in the U.S. exclusively by Environmental Solutions

International (ESI), Inc., of

Reston, Va.

The marine industry has long suffered with problems caused by microorganisms that live and grow in fuel, fuel tanks, cargo, ballast tanks, and lube oil systems. Some water is present in all fuel and the bugs flourish at the oil/water inter- face, feeding on the oil. Engine room temperatures (60-95° F) exac- erbate the situation by providing ideal breeding conditions. Left unchecked, the bugs quickly multi- ply and clog filters, fuel lines, and corrode injectors, leading to equip- ment breakdown and failure. The patented De-Bug Unit passes the diesel fuel through vertically stacked ceramic permanent mag- nets - TRI-MAG™ or MULTI-

MAG™ Bug Killer Paks. Within the designed path, the fuel and microbes experience many flux field changes and intensity capable of destroying nearly 100 percent (97.6 percent) of the microorgan- isms in a single pass. An example is the DSESS Kellie Chouest, a 310-ft. Deep Submergence Rescue

Vehicle Support Ship equipped with twin EMD 645 diesel engines.

Leased to the U.S. Navy for research, rescue and retrieval, the vessel cannot risk engine power loss or shutdown. However, severe algae contamination of the fuel required replacement of the fuel filters on all engines every few

Wherever cables are - MultiDiameter seals

It adapts to the size of the cable

Combining safety against fire, gas and water with the benefits of

MultiDiameter technology makes Rox System the outstanding choice for marin environments. Installation is fast and easy thanks to the "peel off" technology of the adaptable modular seals. Remove a few sheets and the module fits perfectly. It provides you with • qualified safety • worldwide availability • system features • extensive support

Installing De-Bug Units in the fuel supply lines to the main, generator, and auxiliary diesel engines solved the problem, extended the filter replacement interval to the normal mainte- nance schedule, and restored the engines to their required standard of dependability. Captain Eugene

Thomassie said, "We are well sat- isfied with the performance of the

De-Bug units."

A 100-ft. utility vessel, the M/V

Skippin Sue, owned by T.E.

Marine, Larose, La., reportedly experienced similar problems. In

May, filters on the DDI 12V-92 main engines were being changed two to three times per week due to microbial clogging.

After De-Bug installation, the initial filter change interval reportedly increased to two weeks, and one month later the filters are still clean. Tillman Danos, a T.E.

Marine principal says, "...it's great ... really doing the job. (We) will put them on all the other boats..."

A major oil company's offshore drilling platform in the Gulf of

Mexico experienced severe prob- lems with diesel engine perfor- mance and dependability caused by contaminated fuel stored onboard. Fuel filters had to be ser- viced every one to two hours. Re- circulating the fuel through a large

De-Bug Unit Model L-4000, helped eliminate the problem by continu- ously treating the stored fuel before supply to onboard engines.

De-Bug Units are available in a complete range of sizes for all applications. The exclusive U.S. agents, ESI, Inc. are staffed by marine engineers with 70 years experience in fuels and lubricants who provide practical advice and optimal solutions. ESI also offers total fuel management systems and an international used-oil analysis service.
