Mobil Joliet (continued from page 33) a total capacity of some 75,000 gal- lons, two wash water tanks having a total capacity of 7,000 gallons, two potable water tanks with a total capacity of 9,000 gallons, a 2,600- gallon bilge holding tank, one 1,800- gallon sewage holding tank, two 1,300-gallon lube oil storage tanks, and a 2,600-gallon dirty oil holding tank, all built into the hull. NEW HIGH EFFICIENCY ON THE HIGH SEAS WITH MAXIM® HEAT RECOVERY SILENCERS AND MAXIM® HEAT RECOVERY EVAPORATORS ENERGY CONSUMPTION = ZERO These small Maxim Heat Recovery Silencers also include spark arresting, and generate over 6,000 #/hr of 60 psig steam from propulsion engine exhaust heat. Units are aboard the Falcon Leader, built by Bath Iron Works Corporation. Steam produced is used for the tanker's heating system, evaporators, and for tank cleaning. HEAT SOURCE = FREE Maxim Thermal Circulation Flash jacket water heat recovery evaporators each provide 11,000 gpd of 2 ppm fresh water. Two units are aboard this Atwood Oceanics, Inc. rig. Shenandoah, shown operating in the Arabian Sea. All material in contact with sea water is of 90-10 copper nickel alloy for maximum corrosion resistance. RO.

Circle 326 on Reader Service Card 1984 Propulsion power is provided by two Wartsila 12V22HF diesel en- gines capable of burning blends of residual fuel, each developing 1,800 bhp at 900 rpm. These drive two five-bladed, stainless steel 102-inch propellers through Lufkin RHS 3022 offset reduction gears. The en- gines and gears are cooled with water circulated through a St. Louis Ship-designed skin cooling system. The engines can be started from the engineer's control booth or the pilothouse, and are controlled by Tracor Marcon equipment installed in both loctions. The new towboat is equipped with a Tracor Marcon monitoring system that features a video moni- tor in the engineer's control room, the pilothouse, and the engine room. The system is designed to accept information from 168 sensor inputs, which include various parameters such as pressures, temperatures, switch closures, rates, voltages, etc. A Matthews electro-hydraulic, two-speed power package having two service and one standby dual- output pumps provides the power to the hydraulic system for the two steering and four flanking rudders. This system provides for electrical wiring and mechanical linkages for follow-up in the steering compart- ment. Electric power is supplied by two GM Detroit Diesel 125-kw diesel generator sets. A Simplex deadfront switchboard is wired for parallel op- eration of'the generators. The engine room is soundproofed and is provided with overhead trol- leys and hoists port and starboard. Each generator room is partitioned off by soundproof panels for isolat- ing the diesel generator sets. Deck machinery consists of one Schoellhorn-Albrecht 10-hp, motor- driven, double-barreled capstan; two Beebe 5-hp, motor-driven win- ches; and a Sasgen derrick boat dav- it located aft on the second deck to handle supplies and a small work- boat.
