New Transmission

Accessories Bulletin

Offered By Twin Disc

Twin Disc, Inc., has just re- leased an updated 12-page bulle- tin covering accessories available for its line of marine transmis- sions in the 52 to 1,193-kw (70 to 1,600 bhp) range, suitable for die- sel engines.

New information includes speci-

FERNSTRU fications on input hub assemblies designed to fit Vulastik torsional couplings. The bulletin also con- tains basic capacity and dimen- sional data on the company's standard and multi-pump PTO's, top PTO's, live PTO's, indicating gauges, output shaft flanges, troll- ing valves and heat exchangers.

The crane ship Titan-1 (shown above) was delivered recently at the

Wartsila Turku Shipyards in Fin- land. Ordered by Sudoimport as the first in a series of four identical ves- sels, the Titan-1 is said to be the world's biggest catamaran ship, and is intended for hoisting and installa- tion duties in the offshore oil fields.

She is a single-deck vessel, with engine room, accommodations, and bridge located far forward, and pro- pulsion motor rooms, diving station, and workshops aft.

The catamaran has a maximum overall length of 464 feet, beam of 177 feet, and depth of 42.65 feet.

The propulsion machinery is diesel- electric. Total output of the three diesel engines manufactured at the

Wartsila Vasa factory is 7,550 bhp; output of two electric propulsion motors is 3,400 kw, and that of the two bow thrusters 800 kw. The ves- sel's speed is 11 knots.

Unlike most of the large offshore cranes today, the crane of the Titan- 1, manufactured by Kone Oy, is the center-pillar type, partly because it is situated on one of the hulls and because of the very high free space requirement under the boom. The capacity of the two main hooks is 300 tons each; together they lift 600 tons at an outreach of 128 feet, or 150 tons at 226 feet. Total installed power of the all-electric crane is 2,350 kw.

The vessel is equipped with com- plete offshore construction equip- ment, including steam hammer, pile-boring gear, automatic flame cutting and welding equipment, platform leveling equipment, and a diving station with decompression chamber for three divers and one doctor. The craneship, with its eight 10-ton anchors, can be moored in water depths of up to about 650 feet.

When hoisting, the catamaran concept is advantageous due to its inherent good stability. As the world's largest catamaran, the Ti- tan-1 was a formidable challenge to the Turku Shipyards. New calcula- tion methods had to be developed as there were available neither classifi- cation society rules nor ready-to-use calculation methods concerning the seakeeping characteristics and the hull strength of a catamaran vessel of this size.

Two of the vessels in this series of four will be delivered in sections for assembly at a Soviet shipyard under

Wartsila supervision. The transport will take place via the Volga waterway, the hulls separately and the deck and deckhouse in sections.
