Machine Construction plant in Sormovo but construction was not even
finished when World War II broke out. It was held up for quite a long

long before World War II. Originally it was intended to build the
tanker on the model of the large tonnage tankers"?S=URUPA",. "ZHDANOV;
"LENIN," etc, which had been built at this plant for the Kasptanker Line.
Since the power plants of the tankers In operation proved unsatisfactory,
(cumbersome compressor Diesel engines as power plants), design and
installation of a better power plant for this vessel was ordered.
Whether the Sormovo plant designees were not able to carry out this ,;ob
or whether they could not find a suitable power plant (most probably
the latter, at any rate, the question of installing a more modern
power plant in this tanker came up only, aOtez.the ship hull had been
built), at any rate the ship was not built.. tc:

propellers to rotate.
;. tankers. Diesel generators which are standard equipment on maa ~n-lire
railroad motor locomotiv were used as main Diesel enerators on
They are engines of the "D-50" type, which usually have 1,000
effective HP with 740 revolutions per minute. Since the middle
(rc-?efflcient of power utilization of maritime ship engines represents
0,95-1.0 against 0.7-0.75 for locomotives, the "D-50" engines were
made to render a slightly lower capacity on the tanker, that is,the
capacity of each engine installed on the tanker consists of 900
^ffective HP with 720 revolutions per minute. The "D-50" engine is a
six-cylinder, four-tact engine without compressor; simple action with
supercharger. The cylinder diameter of the Diesel engine is 318 mm,
piston stroke 300 mm. The pistons are made of alluminum alloy and

exhaust gases. The rotor of the blower can make up to 13,500
revolutions per minute and provide up to 10,000-13,500 cubicmeters of
aL.= per hour.
8. The engine is cooled with fresh distilled water. The cooling system is
fully circulatory. The engine has pressure lubrication. When pressure
of lubricant falls below 1.6 kilogram per square centimeter the
engine stops automatically. The engine has a safety regulator which
stops the Diesel by means of a fuel pump if revolutions of the Diesel

9. The electric power station of the Diesel-electric sip consists of four
(rotated by "D-50" engines) continuous current generators each putting
out 700 KW, 700 Volt, designed to feed ship propeller unit electro-motors,
but alto electro-motors of loading pumps. The generators form a common
unit with the Diesel (not counting the couplings)., Four auxiliary
generators of 70 KJ each, 230 Volt, which feed auxiliary equipment when
ship is in motion, are connected with the free ends of main generator
shafts.
10. When the vessel is stopped with no loading operations in process or
while cargo is being fed to the tanker by shore-based pumps, feeding
of auxiliary equipment is done by the auxiliary Diesel generator
11. The propeller engines of the vessel are double-action,ie, they have two
armatures and two magnetic systems in one housing. Engine power is
1750 HP each, Voltage 700 Volts, 128 revolutions per minute. These
engines, formerly serial engines of continuous current used in rolling
mills in the metallurgical industry, were converted into marine engines.

16. The nominal speed of the ship with all four Diesel generators operating
is 11.3 knots. With three generators working (in case one of them
should be in repair while ship is in motion), the speed is 9.8 ]mots,
ie, at the most 13% below nominal speed.
