REVIEW Marine Fuels, lubes & Additives The following article is based on the results of a limited survey of many of the top suppliers of marine lubricants and fuel additives con- ducted by the editors of the Mari- time Reporter & Engineering News. Further information including speci- fications sheets and literature is available on any of the products re- viewed in this article. To obtain the free information, simply circle the appropriate Reader Service Num- ber on the post-paid reader service card bound in this issue. BP Marine Circle 105 on Reader Service Card Offered by BP Marine, ENERSYN, a line of superior, syn- thetic, functional fluids, is designed specifically for those applications on board where fluids having enhanced properties can deliver important benefits. The ENERSYN family of synthetic products spans applica- tions in gas, air and refrigeration compressors, as well as centrifuge gearboxes. ENERSYN GCS 180 is a lubri- cant based on specially selected poly- ethylene glycols. ENERSYN GCS 180 has been approved for both ro- tary and reciprocating machinery types and for most of the gas cargoes commonly transported on ship. ENERSYN RX100 is a diester-based lubricant. It is the recommended product for reciprocating air com- pressors in ships and it greatly im- proves valve and cooler cleanliness, thus reducing engine-room mainte- nance workload and parts replace- ment costs. ENERSYN RC-S 32 is a synthetic lubricant, based on polyalphaolefins, that offers special performance fea- tures in rotary air compressors on board ships. ENERSYN HTX 220 is based on a carefully balanced blend of synthetics and has been devel- oped to satisfy the special lubrica- tion requirements of centrifuge gear- box systems. Cartel Products Circle 104 on Reader Service Card Cartel Products has just intro- duced a new fuel additive that will help your vessel comply with the new government emissions stan- dards. Cartel's Combustion Cata- lyst will reduce Carbon Monoxide (CO) and Nitrogen Oxide (No^) emis- sions up to 55 percent. Along with the reduction in omis- sions, this new generation fuel addi- tive will reportedly increase fuel economy up to 15 percent while re- portedly increasing the power out- put of the engine - torque. The Cartel Combustion Catalyst will also reduce the engine's operat- ing temperature, which means lower engine wear and down-time. July, 1993 Castrol International Circle 28 on Reader Service Card Castrol has introduced Castrol Spheerol SX2, a high performance calcium sulphonate complex base grease. Specifically developed for use in the highly agressive condi- tions found in marine and offshore environments, Castrol Spheerol SX2 is suitable for a wide range of appli- cations including wire ropes, open gears, small to medium sized roller bearings, fairleads, chain drives, etc. Extensive in-service and labora- tory trials have proven the advanced properties of Castrol Spheerol SX2. These characteristics give optimum lubrication and corrosion protection over a wide operating temperature range of -20 to +150 degrees Celcius, ensuring maximum intervals be- tween services. The NLGI rating of this grease is 2 and drop point in excess of 300 degrees C. Chevron Circle 29 on Reader Service Card Chevron USA Products Company markets a variety of premium lubri- cants in the U.S. These include: —Chevron Marine Engine Oils Delo 477 (SAE 30, 40, and 20W-40) - superior high dispersancy, high alkalinity, 17 TBN engine oils. They are for use in diesel engines in tow- boats, tugs, workboats, dredges, and in other marine industrial engine applications requiring a zinc-free oil. —Chevron Marine Engine Oils Delo 1000, 2000, and 3000 Marine (SAE 30 and 40) - high quality en- gine oils developed for use in a wide variety of medium-speed trunk pis- ton engines including the latest de- sign high output engines burning Marine Diesel Oils, or residual fu- els with low, moderate, or high sul- fur content. —Chevron Marine Engine Oil Symbol 9250 - a high quality, high performance engine oil which fully complies with Symbol 9250 of the U.S. Military specification MIL-L- 9000H. Drew Ameroid Marine Circle 30 on Reader Service Card Drew Ameroid Marine offers a highly effective solution for improv- ing the overall efficiency of marine exhaust boiler systems on motorships, as well as minimizing the risk of soot-related damage due to both stack fires and acid corro- sion. A blend of highly active com- bustion catalysts, Drew's LT Soot Release™ is a unique powder de- signed both to reduce combustion deposits and maintain clean heat- transfer surfaces in diesel exhaust gas economizers. Drew's LT Soot Release combus- tion catalyst reduces the ignition temperature of the products of in- complete combustion by removing the combustion binders of ash and other bonded deposits. Especially well-suited for the energy-efficient recovery systems in today's motorships, this low-temperature soot remover is activated by exhaust gases with temperatures as low as 200 degrees C to generate a con- trolled oxidation of soot deposits. When this process is complete, usu- ally in 15 to 30 minutes, normal soot- blowing operations remove the loos- ened material. Daily treatment with LT Soot Release can eliminate or minimize the need for periodic waterwashing - and also prevents the progressive deterioration in heat transfer effi- ciency that typically occurs between scheduled cleanings as soot contin- ues to accumulate. Energy loss from soot deposits is thus reduced dra- matically, along with corrosion ef- fects and stack fire potential; and system efficiency is maintained at a consistent level. Elf Lub Marine Circle 31 on Reader Service Card Elf Lub Marine of France stresses quality and safety margin in design- ing marine lubricants. Elf Lub Marine offers the Elf Talusia XT 70 and the Elf Talusia HR 70. The well-known Elf Talusia XT 70 has been further improved and offers enhanced performance through the application of the most recent quality standards. The im- proved Talusia XT 70 is very well adapted for the lubrication of all types of old and modern slow-speed engines and is currently used on more than 1,000 vessels. The new Elf Talusia HR 70 was 31
