Floating Drydock PD-80
Project 98516

A 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.

This is a special floating dock for the experimental submarine SS-533 of Project 1710. It is a metal dock equipped with a portal crane with a lifting capacity of 5 tons. Like the submarine for which it was intended, the floating dock was based on Balaclava. After the collapse of the USSR and the end of operation of the experimental SS-533 submarine, the floating dock was not used for its intended purpose, but began to be used for docking small vessels and fleet boats.

Floating Drydock PD-80 laid down at Kherson Shipyard, commissioned on 30 September 1986 .

Now in service.
