SMM '80 (continued from page 14) est luxury liner in the world, in the space of only 33 weeks. The German shipyards H-DW and Thyssen Nordseewerke also have been making a name for themselves in the market for off- shore rigs and marine technology systems. Werft Nobiskrug has gained access to a broader mar- ket with its standardized multi- purpose freighters, while Oren- stein & Koppel, also in Hamburg, has set new standards in the con- struction of floating cranes, dredges, and refrigerated cargo vessels. Interesting exhibits also will be presented by others in the ship- building sector: Germanischer Lloyd, Deutsche MacGregor, the Hamburg Shipbuilding Research Establishment, numerous manu- facturers of large shipbuilding tools, and the Paul Hammelmann engineering works, which will in- troduce its Dock-knight system for the rationalization of dock- yard and maintenance work. This system has been adopted by ship- yards in West Germany and the world at large. Its fully automatic operation permits the cleaning of a ship's sides at a rate of over 2,000 square meters per hour, and painting at the rate of 4,000 to 6,000 square meters per hour. Propulsion Machinery Prominent At this year's SMMT exhibi- tion, considerable space will be occupied by the diesel engine manufacturers. This will include presentations by diesel engine builders, makers of control sys- tems, manufacturers of rudder propellers and propellers with ad- justable nozzles, as well as sup- pliers of engine accessories, clean- ing materials, and cleaning equip- ment. Among the major firms that will be represented are Klockner- Humboldt-Deutz, M.A.N., MaK, MTU (Motoren und Turbinen- Union), Motoren-Werke Mann- heim, Societe Alsacienne, Gebrud- er Sulzer, Stork Werkspoor, Tech- nocommerz, Centromor, Grandi Motori Trieste, and Hatz. These are just a few examples of the comprehensive and international nature of the Hamburg exhibition. Intermaritec '80 In conjunction with the SMMT exhibition September 23-27, an international congress—Intermar- itec '80—will attract engineers and scientists from the United States, West Germany, Norway, Canada, France, Great Britain, the Netherlands, and even from as far afield as India and the Peo- ple's Republic of China. This valuable exchange of in- formation in the field of marine research and technology will take place parallel with the exhibition. Intermaritec '80 will be spon- sored by the Federal Ministry for 16 Research and Technology. Some 700 experts from all over the world are expected to hear the 67 papers. The congress can be broken down according to four main topics: offshore technology, polar maritime technology, marine pollution control, and navigation and communications at sea. The congress has been orga- nized by the Deutsche Komitee fur Meeresforschung und Meeres- Now Twin Disc offers the North American marine industry five new series of marine reverse and re- duction transmissions for higher horsepower diesel engines. Twin Disc has extended its line of do- mestically manufactured trans- missions to include higher horse- power models from its partially- owned affiliate Niigata Converter Company Limited (NICO). This means the superior reliability, performance and operating eco- nomics typical of Twin Disc Marine Transmissions are now available here in greater horsepower capacities than ever. These larger, coaxial (inline) marine transmissions are desig- nated Models MGN-650BZ, MGN- 1000AZ, MGN-1600AZ, MGN-2200AZ and MGN-3200AZ. In addition, special designs and other NICO models are available in produc- technik (German Committee for Marine Research and Oceanog- raphy), the Wirtschaftsvereinig- ung Industrielle Merrestechnik (Trade Association for Industrial Marine Engineering), Dusseldorf, and Hamburg Messe und Con- gress GmbH. Offshore Platforms Within the field of offshore technology, experts from the tion quantities to meet specific in- stallation and application re- quirements. The MGN-Z Series Offers these Features: • Coaxial input-output shaft ar- rangement for lowered propul- sion package center of gravity. • Wide variety of models and ratios to meet various propulsion reauirements. • Use same type oil as specified for the engine. • Carburized, hardened and pre- cision finished single helical gearing, anti-friction bearings, and hydraulically-actuated clutches are the principal members of the uniquely- designed gear train resulting in a dimensionally compact, low weight, high efficiency transmis- sion. • Prompt, smooth shifting, integral Hamburg shipyard of Blohm + Voss and the Norwegian indus- trial firm Kongsberg Vaapenfab- rikk will present models for po- tential international cooperation in the development and construc- tion of offshore rigs for deepsea engineering. A team of interna- tional experts will deal with the testing of new or recently devel- oped working platforms and drill- hydraulic forward and reverse clutches respond to operator requirements for good vessel maneuverability. The "X" control is available as an option which permits variable propeller speed independent of engine speed. • Housing design and strategic placement of access covers provides for easy inspection and maintenance, even in compact engine rooms. The MGN-Z Series, like all Twin Disc Marine Transmissions, are backed by Twin Disc's warranty program with Approved Renewal Parts available from Twin Disc.
