THE APPRAISAL OF CONTENT IS TENTATIVE.
(FOR KEY SEE REVERSE)
1. Technical data on the 1,100-ton Danube ocean going vessel include the following:
Length of ship 73.2 m.
Width of ship 9.9 m.
Height of side 4.7 m.
Draft 3.1 m.
Ocean cargo tonnage 1190 tons
Capacity per ton of cargo 3.65 cu. m.
Ocean speed 10.5 miles per hour
Danube speed 18.2 kilometers per hour
2. The ship is driven by two Ganz-Jendrassik diesel engines of 400 horsepower, 800
revolutions per minute, each.
3. The interior of the hull is welded and only the exterior, which is exposed to the
water, is riveted. For the sections exposed to heavy torque, chrome amalgamated
steel of 50-60 kilogram per square millimeter tensile strength was used.
4. The ship has four large holds with four cranes, each of which can lift a two-.ton
load with a speed of 18 m. per minute.
5. A water ballast space is located between the second and third holds. It enables
the ship to travel without cargo, or when carrying only light cargo.
6. The motor ship TISZA is equipped with two diesel engines of 400-horsepower each,
which are driven directly by a single-stage gear transmission with double helical
gear. Reversal of the engine is effected in 15 seconds by a mechanism operated by
an e.ir-servomotor. The weight of one engine plus the directional coupler is 14 tons.
At the request of the USSR, however, the ships have to be equipped with diesel
electric drive.

7. The auxiliary equipment is driven by two 35 kilowatt diesel-generator engines.
The living quarters are electrically heated. While the ship is in motion, one of
the auxiliary generators supplies the necessary current for lighting and the operation
of signaling apparatus. In harbor the current is supplied by storage batteries.
8. The steering equipment is of the 3-paddle Hitzler type.
9. At the request of the USSR the following essential alterations have been made on
this type vessel since the beginning of 1954:
a. The outer plating of the hull is also completely welded. Large pieces, each
weighing 2-3 tons are welded together in advance in the shop and are then assembled
on the shipway.
b. The capacity of the machinery has been considerably increased, although the
exterior measurements of the ship have remained unchanged. One 1200-horsepower
Ganz-Jendrassik diesel engine has replaced the two 400-horsepower diesel engines.
The diesel-electric drive remains unchanged; each of the two propellers is driven
by a 600-horsepower electric motor.
