Hitachi Reveals Turbine

And Boiler Program

Hitachi Zosen, with head offices in Osaka, Japan, has announced the establishment of a joint pro- gram with Kawasaki Heavy Indus- tries, Ltd. for the manufacture of marine steam propulsion equip- ment, including marine steam tur- bines and marine steam boilers, all of fully-domestic design. This pro- gram has been set up to meet the need for increasing the output of the propulsion machinery in re- sponse to the trend for ships to become larger in size.

The first marine steam turbine unit to be manufactured under this program has been completed at the

Sakurajima works. This unit is of the UA-360 type, with a maxi- mum output of 36,000 shp on one shaft. It is to be installed on a 226,300-dwt tanker under construc- tion at Sakai Shipyard for Regent

Shipping Co., Liberia. The UA- 360 unit consists of a cross com- pound impulse turbine with double reduction gears; it has a normal output of 35,000 shp (maximum of 36,000 shp) and is said to be the largest in commercial operation.

The weight of the unit is 300 tons and it occupies a space about 36 feet long by 39.3 feet wide by 29.5 feet high.

Three types of steam turbine propulsion units have been devel- oped. They have been designated

UA, UB, and UR and range in out- put from 16,000 shp to 50,000 shp.

The first two steam generators to be manufactured under the pro- gram have also been completed.

They are also of fully domestic design and are to be installed in the Regent Shipping Co. tanker to provide steam for the UA-360 steam turbine propulsion unit.

These two boilers are of the two drum, water-tube type and were constructed at Innoshima Shipyard

They are designated as BD type, and each has a normal evaporation rate of about 121,000 pounds per hour (maximum evaporation rate of about 158,400 pounds per hour) with a weight of 132 tons.

The present manufacturing schedule calls for 3 additional tur- bine units and 6 additional boilers in 1971, 6 turbine units and 12 boilers in 1972, and 8 turbine units and 16 boilers in 1973.

Hitachi Zosen also manufactures the Hitachi B&W diesel engine and has an aggregate production record of 4-million bhp from 1950, when the licensing agreement was concluded with the Burmeister &

Wain Co., through December 1970.

Wrong sized grooves in sheaves and drums can cost you money. "Try working in shoes that don't fit and you'll understand what happens to your wire rope when it operates in grooves that are the wrong size," says Joe Forrester, USS TIGER

BRAND Wire Rope Specialist. "A groove that's too small will pinch your wire rope, causing the wires to wear against each other, and against the sheave flanges. It will also restrict the ability of the rope to con- form to the curvature of the sheave. If the groove is too large, it will not properly support the rope, and under load the rope will become elliptical in shape." "When grooves become worn undersize or corrugated, they should be machined to recom- mended tolerances, or the sheaves should be replaced to prevent undue wear on the rope."
