Ivan Dinitrov Shipyard, Russ
1. Sentry box at the main gate of the shipyard. Main entrance is protected
by one sentry of the police (militia).
2. Plumber shop. Personnel of approximately 30 people work there.
Remarks
No. 1, 2, and 37 sections are quartered in the same building, a one story
tile roof structure built of baked adobe bricks.
3. Athletic Club offices for the shipyard laborers (locomotive).
4. Blacksmith shop. It is equipped with two mechanical hammers of German
make, motivated by compressed air supplied by air compressor unit. Two
small furnaces operate with compressed air from the air compressor unit.
Approximately ten people work at the Aatgoing blacksmith shop.
5. Lathe machine shop. Equipped with approximately 20 lathe machines of which
one is of gigantic size of German make, used for surface smoothing axles
of ships.
6. Machine shop section. Accessories are either made or repaired here. It

Approximate personnel: 50.
7. Fitting section. It is equipped with benches, vices, two , one
special carving electric machine (Raibla of Czechoslovakian make), tool
cabinet No.1 containing all type of tools and implements.
8. Two story structure housing the accounting office staffed by approximately
15 clerks (i.e., cashier, finance agencies). Technical Adviser's office

the technical shipbuilding adviser.
9. Two story building housing the shipyards police force (militia) composed
of approximately ten men. Sections No. 3, 4, 5, 6, and 7, are quartered
in one story tile roof structure built with baked adobe bricks. Whereas
8 and 9 sections are located in two story structures. Section No. it, 5, 6,

10. Floating pier. It floats on two iron barrel pontoons (dimensions: diameter
1 meter; approximate length 5 to 6 meters). They are in a parallel position
three meters each away from the other, tightly combined with iron stakes.
Iron poles approximately six meters high eject horizontally on the exterior
side of the pontoons to support iron plated floor. The foregoing floating
pier was constructed at the Ruse shipyards for the unloading of mechanical
crafts of the Bulgarian river navigation fleet delivered there for minor
repairs (such as on electric wiring installation, anchor winches, etc.).

11. Two story roof tile structure. Shipyard admdniatration offices are
quartered on the first floor consisting of: director's office, office
of the supervising engineer-shipwright, director's secretarial office,
other administration offices. The ground flocor contains food store rooms,
kitchens and restaurants where shipyard personnel are fed. All eat here
at noon. Approximately ten courses are prepared, each ordering to his
accord. Price on each course is approximately from four to ten leva.
Snack is served in the morning but few come.
12. Long, narrow one story building is connected with No. 11 structure. It
shelters seven winches utilized in hoisting the vessels on the two grates
available at the shipyard, of which the first is constructed of cement
and the second of iron (desi ated in pertinent drawing No. 2 under the
letters A and B respectively. The following are likewise designated in
pertinent drawing (No. 2) under respective letters:
a. Seven electric hoist winches utilized for the two grates are located
in structure #12 (building dimensions: approximately 25 meters long
and three meters wide), The wire cables fastemito the runway rollers
are coiled by the winches during hoisting operations, the cables be-
ing funneled from buff ig #12, through apertures which are located
before each winch. Each winch is equipped with a crowbar to uncouple
it from C' axis. Thereby the uncoupled winch does not rotate. There-
fore so many winches may operate as to the load work required by the
grates.
b. Electric generator motivates simultaneously by one axle the fore-
going seven winches. It is a German wake AEG operating with alter-
nating current. Incidentally, the entire plant functions with alter-
nating current.
c. Electric generator axis that motivates all seven winches.
d. Apertures, through which the cable wires pass when beiig coiled
by the winches in hauling the runway rollers. Grate A , made of
cement, consists of seven cement plated platforms submerged in water.
e. Seven cement plated platforms of Grate At.
f. Seven double line rail tracks on each cement platform.
g. In all, there are seven runway iron rollers, each equipped with
eight wheels. Htch roller runs on two iron rail tracks (four wheels
on each track). The platform of each roller is approximately 0.80
meters wide and four meters long. The platform is horizontal and
not slantwLe e. Therefore, it is not parallel with the rail tracks
or with the foundation-of the grate. (See drawing #4.)
h. Cable by which each runway rollers are hauled.

i. Grate A' is of lateral hoist, that is, the vessel is hoisted from
a lateral position and not lengthwise. Two horizontal cube block
platforms are at the top of the grate shaped as two gigantic steps,
the top one 1.40 meters high and the lower one one meter approximately.
(See drawing #5.) The hauled-in ships rest on stumps placed on each
of the two platforms. The two step-shaped platforms are designated
as TH and TH'. The runway rollers which slide on the grate's floor
run transversely along the two step-shaped platforms.
A. The floor of the runway roller is above the floor level of
Step TH and Step TH'. Therefore ships may be hoisted up to the
floor level of Step TH and Step TH'. Floor dimensions of Step
TH are approximately 8 meters wide and 30 meters long. As to Step
TH': approximately 1; meters wide and 30 meters long. Ships do not
rest on stumps placed on floor of Step TH' but remain an the runway
rollers. (Thos the runway rollers are utilised as supporters.)
This is because the runway rollers cannot be further used to hoist
a third ship. Therefore two ships may be hoisted on Grate A, one
supported by stumps on floor TH and the other ship resting on the
runway rollers on floor TH'. Inasmuch as the river boats hoisted
so have flat bottoms (Neel), they rest on the platform of the run-
way roller without support of stumps.
B' letter in #2 drawing designates iron grate. It is constructed
as follows:
Two rail tracks are fastened to iron ties railroad wise. An iron
six-wheel runway roller runs on the tracks (three wheels on each
track). The roller is approximately five meters long and two meters
wide. The level of the platform of this roller is the same as those
of Grate A. Four wooden square beams are screwed on the perimeter
of the roller's platform. Three more wooden beams ejecting on the
sides of the runway roller are placed transversely on top of the
four beams. They too are screwed to the runway roller. The three
beams hold the hoisted ship. On being hoisted by the runway roller
to the foundation wall (as designated under i in drawing #2) the
ship is slide,', over the wooden grate (conven$ional type set on the
ground) to the designated points where repair works are made on
the ground premises of the shipyards. The sliding operation over
the wooden grate is facilitated by rolling pins. For reference,
see Drawing #3. If the vessel is not flat bottomed but has a perpen-
dicular keel, the ship is then supported on the sides by stumps placed
on the three transversal beams of the runway roller. Many a time,
minor repairs such as on axles (withdrawal., etc.) are made on ships
hoisted by the iron grate. The runway roller of Grate B is hoisted
by winch a' after the latter has been uncoupled from runway roller
2 . All Bulgarian war ships and minor tugs are hoisted to the
ground by the grate. The source was employed at the Ruse shipyards
as of 1 January 1955 until 2 July 1956. No ship was built on Orate
A (made of cement) during the foregoing period inasmuch as it was
used for ship repairs. The following are large barges hoisted on
the grate: Vidin, Sousse, Svicstov, Loa, Tutrakan, Ternovo. The
last mentioned (i.e... Ternovo) is a Danube barge hoisted on Step TH

platform of Grate A in duly 1956. It was to be converted into a
sea tug and then to be dispatched to Varna. River boats are not
hoisted exclusively for keel cleaning inasmuch as they do not get
dirty as sea going vessels. The keel is cleaned only upon being
hoisted for repairs.

ing of cast parts. The same shop is equipped with electric cutter (of
German make). It severs metal plates 16 millimeters thick, the one end
of which is attached to a mechanical punch. The foregoing shop is further
equipped with an electric hone, two electric drills ( one of Austrian and
the other of Czechoslovakian make). The switchboard controllin all lights
of the shipyard is in room (designated under #14b in drawing #1) located
in the same building. his indicates metal plate 6 milli tern thick attached
to the wall. It is used as a work bench in finishing miscellaneous metal
plates.
