Project 23040 Diver Support Vessel

The DSV 23040 series boats are equipped with a decompression system for divers. The boat enable divers to work at a depth of 60 meters. The vessels are also equipped with a ROV and a side-scan sonar. The 23040-series boats have FF class. The DSVs feature single-deck steel ice-class hull boat, an aluminum superstructure (wheelhouse) and two-shaft diesel propulsion system with FPPs and bow thruster.

The Project 23040 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. Bor, Nizhny Novgorod Oblast based JSC Nizhny Novgorod Motor Vessel Yard (ZNT Yard) and the Russian Ministry of Defense on July 27, 2017, signed two delivery / acceptance certificates for two offshore SAR / Diving Support Vessels of Project 23040. The boats were named RVK-1229 and RVK-1230 (Hull No 1117 and 1118), the shipbuilding company said 01 august 2017.

On 22 May 2017 the vessels left the shipyard to their homeport of Severomorsk, Murmansk region, where the boats will enter service with the Northern Fleet diving support vessels. The RVK-1229 and the RVK-1230 were the 17th and 18th in a series of 16 DSV/SAR boats initially ordered for Russian Navy. Later the Navy exercised an option for six more ships, to 22 vessels. At the moment 20 vessels of the Project 23040 had been completed. On June 8, the shipyard launched the 19th and 20th boats (the RVK-1239 and RVK-1261). The vessels will soon be undergoing sea trials and handed over to the Ministry of Defense. This duo would also enter service with the Pacific Fleet.

The 23040-series salvage / diving support vessels have proved their capabilities as part of the Northern, Pacific, Baltic fleets and the Caspian Flotilla. At the International Maritime Defense Show in St. Petersburg in late June 2017, the Ministry of Defense introduced among other best ships the SAR/DSV RVK-1064 (Project 23040, YB 2015, homeport Lomonosov, Leningrad Region). Captain Andrey Katin said the boat features excellent accommodation conditions and outstanding seaworthiness of the RVK-1064.

Sergey Konovalov, MD of ZNT Yard told that the Project 23040 series was preceded by ten similar A-160-design boats, so the shipbuilding firm has built so far a total of 30 diving support vessels. "This is a huge series, by today's standards, in the post-Soviet period is a unique achievement," he added.

The new project 23040G was developed by ZNT OJSC. It is a further development of the project of multifunctional road boats of emergency rescue support 23040. A distinctive feature of the new project is that the master can control the movement of the vessel in various modes from both the central and stern posts. For the convenience of the operator and the safety of navigation, there is a quick switch between any mode and the control station.

Two small hydrographic vessels of project 19910, two large hydrographic boats of the new project 23040G, as well as two newest large hydrographic boats of project 19920 and three large hydrographic boats of the new project 23370G will be built for the Russian fleet until 2021. This is stated in a statement released on 02 January 2019 by the press service of the Ministry of Defense.

The shipbuilding plant "Nizhny Novgorod ship" is working on two large hydrographic boats of the new project 23040G. Earlier this company has already completed the construction of two similar projects for the hydrographic service of the Baltic Fleet. The fleet will receive the new ships of the series in 2019.
