Hydrographic vessels and boats ensure navigation in oceans and coastal waters. The activities range from reconnaissance of a water route, seabed survey and research of navigational dangers, hydrographic measurements, search and rescue operations, to intracoastal waterway aids.
One ofย the first modern vessels inย the Russian Navy was the big hydrographic boat BGK-2149. Itย was accepted into service inย December 2016. The Baklan-class project 19920 was designed byย Vympel bureau inย Nizhny Novgorod. The boat has toย replace outdated vessels and expand their capabilities. Automatic navigational and specialized systems promote the fulfilment ofย hydrographic and buoy work inย coastal waters. The boat services navigational beacons, buoys and marks. Itย uses the latest multi-beam survey echo sounder, hydrographic profiler, automatic retrievable hydrological probe, electronic mapping navigational integrated system, satellite radar, etc.

The Nizhegorodsky Teplokhod Shipyard isย building big hydrographic boats ofย project 23040G. The Georgy Zima and the Alexander Yevlanov have been operating inย the Baltic Sea for over aย year. The Vladimir Kozitsky and the Boris Slobodnik will join the Black Sea fleet after trials. The shipyard will hand over toย the Navy another two boats byย late 2021.
Project 23040G boats cede inย displacement toย project 19920, but are comparable inย effectiveness. They can study navigational dangers atย depths ofย 400 meters and survey seabed relief atย aย depth ofย two kilometers. The boats service floating marks, deliver maintenance teams, engage inย search and rescue operations, and provide pilot services toย submarines and large warships. The navigational range isย 2000 miles and the crew comprises nine people.

Hydrographic catamaran ofย project 23370G isย another innovation. The lead vessel was laid onย August 26, 2018 byย KAMPO enterprise. Itย continues projects 23370 and 23370M for the rescue forces ofย the Navy. Aย year after the laying, the modules ofย the 140-ton boat were delivered byย road from Moscow region for the final assembly byย Vyborg Shipyard. The scheme optimally distributes the load onย production capacities and saves the resource ofย the boats during transportation.
Inย late December 2019, theย St. Andrewโs flag was hoisted onย the Mikhail Kazansky lead boat ofย project 23370G. Itย has aย catamaran design which expanded the deck space for hydrographic equipment. Although the boat has aย size ofย 25ร8.5 meters, itย isย more stable and easy for buoy setting. The 1.5-meter draft allows operating inย shallow waters.
The boat carries modern equipment, including a survey echo sounder, a multi-beam echo sounder for information collection and processing, an autonomous hydrological probe and other devices. The boat is equipped with a modern navigation and communication system, a radar and an electronic mapping system.

Another innovation isย aย small hydrographic boat ofย project 19910. The Nikolai Skosyrev lead boat was laid inย December 2015 byย Vympel Shipyard inย Rybinsk. Its navigation range isย 3500 miles and cruising capacity isย 25 days. The crew increased toย 17 men.
The boat operates a multi-beam echo sounder which provides 3D seabed relief in real time. The ice-class stem provides for operations in a complicated ice situation at temperature of minus 25 degrees.
The Nikolai Skosyrev has toย join the Northern fleet inย 2020. Itย isย undergoing trials atย present. Inย January 2019, the Rybinsk Shipyard laid another boatย โ the Yakov Lapushkin. Itย has toย goย toย serve inย the Baltic Sea inย 2020, the Army Standard said.

Naval News comments:
The above report by the Army Standard and TASS omitted another large vessel: The Academician Ageev (serial number 451) of project 16450. It was developed by Severnoye Design Bureau and is fitting out stage at JSC “Kanonersky Shiprepairing Yard” in St. Petersburg.

Academician Ageev is being built for the Main Directorate for Deep-Water Research (GUGI) of the Ministry of Defense of the Russian Federation. GUGI is responsible for fielding specialized submarines, oceanographic research ships, undersea drones and autonomous vehicles, sensor systems, and other undersea systems.
