On September 27, 2014, ZNT Yard and RF Ministry of Defense signed acceptance/delivery certificates for two multipurpose offshore search and rescue boats of project 23040 (Hull No No 1115-1116), the shipyard says.
In late March 2013, ZNT Yard signed a state contract for the construction of 16 SAR boats of 23040 design ordered by Russian MoD.
The single-deck steel ice-class hull boat has an aluminum superstructure (wheelhouse) and two-shaft diesel propulsion system with FPPs and bow thruster.
Vessel general characteristics:
LOA – 28.09 m, breadth overall – 5.56 m, depth – 3.4 m, mean draft – 1.5 m, full displacement – about 118 tonnes, propulsion system: main 2x441kW engine and 2x80 diesel generator and an emergency 20kW DG, operational speed – about 13.7±0.3 knots, complement – 3 crew members and 5 divers.
The 23040-series boat was designed for diving support of underwater works at depths of up to 60 m at sea state No 3 of BS (gentle breeze); to perform diving operations by two divers simultaneously with air consumption of up to 120 l/min at a depth of 60 m on the seabed for 60 minutes; availability of decompression. 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 stricken 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 stricken vessels.
JSC Nizhny Novgorod Motor Vessel Yard (ZNT Yard), based in Russia's Nizhny Novgorod region, was founded in 1911.
