floating drydock is a type of pontoon for dry docking ships, possessing floodable
buoyancy chambers and a "U"-shaped cross-section. The walls are used
to give the dry dock stability when the floor or deck is below the surface of
the water. When valves are opened, the chambers fill with water, causing the dry
dock to float lower in the water. The deck becomes submerged and this allows a
ship to be moved into position inside. When the water is pumped out of the chambers,
the dry dock rises and the ship is lifted out of the water on the rising deck,
allowing work to proceed on the ship's hull.
The project of a large floating
dock of the composite type, designed for dock and repair work on ships and ships.
These floating docks were built between 1968 and 2010 at the Pallada Shipbuilding
Plant, Kherson, for both civilian and military customers. In total, about 40 floating
docks in various modifications were built under this project, of which 6 units
(for the Navy) were transferred to the customer from 1974 to 1991.
floating dock, non-autonomous for energy supply. It has a composite structure:
the pontoon is reinforced concrete, and the towers are steel. The height of the
floating dock pontoon of this project is 4.8 m, and the height of the tower is
10 m. It is equipped with two gantry cranes with a lifting capacity of 5 tons
each. The depth of immersion of the slipway deck is 7 meters, and the depth of
immersion above the keel blocks is 5.7 m.

at Pallada Shipbuilding Plant, Kherson (yard No.238), commissioned on 1991.
