Diesel Power Review (continued) STEWART & STEVENSON Circle 72 on Reader Service Card Stewart & Stevenson Services, Inc., with branches in Harvey, La., and Houston, Texas, is one of the world's largest distributors of diesel engines with Detroit Diesel and General Motors-EMD engines from 50 to 4,300 hp. With a normal inventory of hundreds of diesel engines and gen- erators, a staff of experienced me- chanical, electrical, and marine en- gineers, along with 24-hour world- wide parts and service, Stewart & Stevenson offers an excellent sup- port network to its customers. Full service branches, two reman- ufacturing plants, and over 200 dealers are ready to provide full ser- vice to customers, from financing a vessel to training and technical sup- port. Stewart & Stevenson can provide custom engineered power systems for all marine applications. Reintjes gearbox, fixed-pitch pro- peller, PTO gearbox, controls and all other necessary ancillary equip- ment. The Sulzer 6S20 diesel en- gines develop 870 kw (1,185 bhp) each at 1,000 rpm. The re-engining of the vessels will provide them with higher speed ca- pability. With cylinder dimensions of 200- mm bore and 300-mm stroke, the S20 range of six-, eight- and nine- cylinder engines offers power out- puts between 570 and 1,350 kw at speeds of 720-1,000 rpm. Using technology proven in Sulzer's large four-stroke engine types, the S20 has benefits of: (1) full heavy-fuel operation (700 cSt) and increased performance with marine diesel oil; (2) clean combustion, even at part load, without a need to use a charge air heating system in low-load oper- ation; and (3) designed for high reli- ability and durability with two-year overhaul intervals.

SULZER Circle 73 on Reader Service Card The new 354-foot Swedish ice- breaker Oden features Sulzer diesel engines for both her propulsion and auxiliary duties. She is propelled by four Sulzer eight-cylinder ZA40S medium-speed diesel engines with a total power output of 18,000 kw (24,500 hp) at 510 rpm. In addition, the ship's electrical requirements are met by four Sulzer 6AT25H aux- iliary diesel engines, each of 1,270 kw (1,730 bhp) output at 1,000 rpm. Both main and auxiliary engines were built under license in Poland. The diesel-mechanical machinery arrangement of the 13,000-ton Oden represents the latest state-of-the- art technology in icebreaker design. The 8ZA40S main engines drive twin CP propellers through gearing and thereby end a diesel-electrical tradition in Baltic icebreakers that has lasted over 50 years. The change came principally because of machin- ery cost and fuel consumption but was also supported by past success with diesel-mechanical machinery in other icebreakers in other coun- tries. In addition, the Oden rein- forces Sulzer's leading position in the icebreaker market. Some 299 Sulzer medium-speed diesel engines totaling about 1,026 MW (1.4 mil- lion bhp) have been installed in, or ordered for, 116 icebreaking ves- sels. In other company news, Sulzer marked its first Sulzer S20 marine propulsion system installation when Pesquera Loa Norte SA of Chile ordered seven of the units for re- engining of seven fishing vessels. Each propulsion system includes a six-cylinder S20 diesel engine, Circle 126 on Reader Service Card The great majority of diesel engine: over 500 kW have BBC turbochargers, S( an extraordinarily wide-spread, fast ant efficient service organization to span you nasty surprises will come as no sur prise.
