SMM 80

9th Exhibition And Congress Ship, Mad mery, Marine Technology International Amid general signs of a worldwide recovery in the shipbuilding industry, the 9th Exhibition and Congress of Ship, Machinery, Marine Technology International will be held in Hamburg, West Germany, from September 23 to 27, organized by Hamburg Messe und Congress GmbH.

Some 450 exhibitors from 24 countries—including all European shipbuilding nations—will occupy the 52,500 square meters of the Hamburg exhibition halls. The range of sectors represented at the exhibition is equally comprehensive: shipyards for vessels of every size, manufacturers of engines and related propulsion machinery, navigational aids, measurement and control equipment f o r automated and semi-automated operation of vessels, as well as outfit and equipment for both deck and engine room.

This extensive display of marine technology will be supplemented by the concurrent exhibition IOPPEC '80 — t h e International Oil Pollution Prevention Exhibition and Congress.

Major European shipyards will present their latest products and ideas for the construction of new ships, ship repair, marine technology, and mechanical engineering.

Among the companies that have registered for the exhibition are Blohm + Voss of Hamburg; Bremer Vulkan shipyard in Bremen ; the Polish shipyard organization Centromor; the Budapest, Hungary, works for ship assembly and crane construction; Maritimex shipbuilding organization (Czechoslovakia) ; the Finnish shipyard Wartsila of Helsinki; S e t e n a v e in P o r t u g a l; Howaldtswei'ke-Deutsche Werft (H-DW) of Hamburg/Kiel; the Hapag-Lloyd shipyard in Bremerhaven; and many other major shipbuilders.

The major shipyards share a growing conviction that the rationalization of capacity for construction of new vessels and the recovery in demand for shipbuilding and ship conversion have created a marked improvement in business prospects. Many European shipyards, particularly in West Germany, are following the trend toward increased specialization by devoting a considerable part of their scientific and technical resources to the development of specialized vessels, floating production plants, and installations for offshore work and marine engineering.

For example, Bremer Vulkan shipyard in Bremen leads the world in the construction of containerships, with 28 completed to date, while the Hapag Lloyd yard in Bremerhaven recently impressed the world of shipbuilding with a record performance in c o n v e r t i n g the passenger ship France into the Norway, the larg- 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 offshore rigs and marine technology systems. Werft Nobiskrug has gained access to a broader market with its standardized multipurpose freighters, while Orenstein & Koppel, also in Hamburg, has set new standards in the construction of f l o a t i n g cranes, dredges, and refrigerated cargo vessels.

Interesting exhibits also will be presented by others in the shipbuilding sector: G e r m a n i s c h er Lloyd, Deutsche MacGregor, the Hamburg Shipbuilding Research Establishment, numerous manufacturers of large shipbuilding tools, and the Paul Hammelmann engineering works, which will introduce its Dock-knight system for the rationalization of dockyard and maintenance work. This system has been adopted by shipyards 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 exhibition, considerable space will be occupied by the diesel engine manufacturers. This will include p r e s e n t a t i o n s by diesel engine builders, makers of control systems, manufacturers of rudder propellers and propellers with adjustable nozzles, as well as suppliers of engine accessories, cleaning materials, and cleaning equipment.

Among the major firms that will be represented are Klockner- Humboldt-Deutz, M.A.N., MaK, MTU (Motoren und Turbinen- Union), Motoren-Werke Mannheim, Societe Alsacienne, Gebruder Sulzer, Stork Werkspoor, Technocommerz, C e n t r o m o r , 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—Intermaritec '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 People's Republic of China.

This valuable exchange of information in the field of marine research and technology will take place parallel with the exhibition.

Intermaritec '80 will be sponsored by the Federal Ministry for 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 organized by the Deutsche Komitee fur Meeresforschung und Meeres- technik (German Committee for Marine Research and Oceanography), the Wirtschaftsvereinigung I n d u s t r i e l l e Merrestechnik (Trade Association for Industrial Marine Engineering), Dusseldorf, and Hamburg Messe und Congress GmbH.

Offshore Platforms Within the field of offshore technology, e x p e r t s f r om the Hamburg shipyard of Blohm + Voss and the Norwegian industrial firm Kongsberg Vaapenfabrikk will present models for potential international cooperation in the development and construction of offshore rigs for deepsea engineering.
