Each of the four thrusters specified for this vessel, rated at 1,150 hp per shaft, were manufactured by Bird-Johnson Company's licensor, Karlstads Mekaniska Werkstad (KMW) of Sweden. To meet the exact maneuverability re- quirements of such special-purpose ships, the thruster was designed to rotate in any direction in the horizontal plane. Maximum thrust control is also made possible by vary- ing the pitch of the blades and by utilization of full-engine horsepower in off-design con- ditions. Both magnitude and direction of thrust are controlled by a single lever in the pilothouse. The thruster can be lifted for inspection or removal without drydock- ing the vessel. The KaMeWa rotatable thruster has been put to extensive laboratory and in-field tests, including a full-scale barge test simulating the actual ship installation in which all per- formance specifications were met or exceeded. For a complete description of the KaMeWa rotatable thruster, write to Ole H. Midttun, Bird-Johnson Company, 110 Norfolk Street, Walpole, Mass. 02081. Caterpillar Announces Two New Marine Transmissions Caterpillar has announced two new marine transmissions—the 7221 and the 7211. Both are compact, single-reduction, layshaft de- sign transmissions. They are designed for the Cat 3412 and 3408 Marine Diesel En- gines in heavy-duty applications, such as fishing vessels and tugboats. In both trans- missions, oil-actuated clutches are designed to operate without adjustment. Helical gear teeth assure quiet, smooth-running opera- tion. The 7221/7211 are engine-mounted transmissions with ratios from 2.0:1 to 6.0:1. Both can transmit full-rated power continuously in forward or reverse. The new 7211 transmission had its first U.S. showing as the highlight of the Cater- pillar exhibit at "Fish Expo '77," October 14- 17, 1977 in Seattle, Wash. In addition to the Cat 3408/7211 propul- sion package, the 3412/7231, a 3306T Marine Generator Set, and a 7271 Marine Transmis- sion were also shown. Four videotapes will be available for viewing on the topics of the Mapleton Foundry, the Basic Engine Plant, the 625-inch Vees, and Caterpillar Engine usage around the world. Further information on Caterpillar Ma- rine Transmissions is available by writing to Charles H. Bolton, Caterpillar Industrial Division, Peoria, 111. 61629. F.W. Hartmann & Co.
