Professor Eike Lehmann, GL executive board member and professor at the Technical

University of Hamburg-Harburg, said the colli- sion test would provide data which would help verify the actual characteristics and qualities of double-hull structures. double bottom, thus corresponding to the entire depth of the ship.

This represents a double side-skin structure with three stringer decks and several vertical frames.

The ramming bow, also reduced to a scale of 1:3, corresponds to the bulbous bow of a 40,000 ton vessel, and was programmed to hit the vessel going six knots at the mid- dle transverse, and to penetrate the outer and inner skin if possi- ble. This was the plan, because only then could it be possible to measure the energy absorbed by the side structure up until rupture of the inner hull. The energy con- tribution required to tear open the inner skin represents the limit value for the collision safety of the structure.

Complete Packages To Start

Gas Turbines

For 20 years Voith has supplied gas turbine manufacturers with hydrodynamic torque converters to start gas turbines. For five years, complete start-up packages, comprising motor, converter, turn- ing device, base frame and oil sup- ply system have been delivered by

Voith. The maximum power for which the start-up torque convert- ers have been supplied to date was approximately 9,000 kW.

Laser Alignment Accurately

Machines joined by space-sav- ing cardan shafts posed a chal- lenge for shaft alignment.

Priiftechnik AG reportedly has an answer to that challenge via its new cardan shaft accessory brack- et for its Rotalign system. The arrangement reportedly yields extremely accurate results, even over separations of up to 33 ft. (10 m), in a very short time.

FINCANTIERI IS

BUILDING FOR THE SEA

Advanced design and production technologies, and a more than two centuries' long tradition behind: Fincantieri is the heir to the Italian oldest and most illustrious companies in the field, and has thus been able of consolidating and continuously updating a unique wealth of experience through the construction of more than 7,000 vessels. Fincantieri, which is today the largest shipbuilding group in the Mediterranean and one of the largest in Europe, is capable of giving innovative and customer-tailored answers to all the needs of those who work for the sea: Merchant vessels of all types, shipconversions, floating offshore units, naval vessels and submarines, large and medium size diesel engines.
