boat of Project 23040 is designed for stationary placement of diving equipment,
transportation of divers and underwater operations. The vessel can assist in emergency
rescue operations, in hydraulic and salvage operations; inspection of harbor seabed,
inspection of ship wrecks and other structures. Besides, the boat has fire fighting
capabilities for fighting fires on vessels, floating and coastal facilities of
total height of up to 30 m, for pumping water from excluded ships; for underwater
search and inspection using unmannded ROV; for search of wrecks at depths up to
150 m, using a towed sonar; for man overboard search / rescue using thermal night
vision systems; for the supply of power to excluded vessels.
series boats are equipped with a decompression system for divers. They provide
decompression, air, oxygen and helium regimes of medical recompression. The boat
enable divers to work at a depth of 60 meters.
The boat is 28,09 meters
long and 5,56 meters wide. The midship board is 3 meters high, the bow is 3,4
meters high. The average draft is 1,5 meters. Full displacement is close to 118
tons. The main engine has a 2x441 KW capacity. The diesel generator has 2x80 KW.
The emergency diesel generator has 1x20 KW. The speed is close to 13,7 knots.
The crew comprises 3 men and the diving team has 5 men. The range is 200 miles
at 10 knots. The boats feature single-deck steel ice-class hull boat, an aluminum
superstructure (wheelhouse) and two-shaft diesel propulsion system with FPPs and
bow thruster. The boats are for the first time controlled by joysticks which easily
keep them in the assigned point in any conditions.
Diving boats of this
project served on all fleets of the Russian Federation. In total, more than 20
boats of this type were built.
