This Project of small civil tugboat was designed
in 1948 by the Arcticproject, Murmansk. The tugboat
is designed to perform towing and berthing operation
at the port, at harbor anchorage area, in rivers
and sea basins, and other tasks. Tugboats of this
project in various modifications served on all
fleets of the USSR and later - the Russian Federation.
The hull of the tugboat is steel, single-deck,
with a single deckhouse with an icebreaking bow
and transom stern, divided into compartments by
five watertight bulkheads. The vessel is adapted
to overcome the continuous course of continuous
ice with a thickness of 20-25 cm and forcing ice
up to a thickness of 40-50 cm. The powerplant
of the tugboat is diesel, twin-screw with fixed-pitch
propellers in fixed nozzles. The radius of circulation
at full speed is 15 meters, while the engines
are run wild - the boat makes a turn
in place. The thrust on the hook is 3.52 t.
Tugboat BUK-49 laid down at Maymaksan Shipyard,
Arkhangelsk, commissioned in 1965.
