hydrographic survey ship is a vessel designed to conduct hydrographic research
and survey. Nautical charts are produced from this information to ensure safe
navigation by military and civilian shipping.
The Project 872 Finik Class
hydrographic vessels has a length of 61,3 m, a width of 10,8 m and a draft of
3,2 m. The vessel has a standard displacement of 939 tonnes and full load displacement
of 1190 tonnes. It has a maximum speed of 13,4 knots, range of 4356 nmi at 11,8
knots and an endurance of 15 days. The vessel is equipped with 2 Mius navigation
radars, Rumb radio direction finder. The vessel is powered by two 960 hp Cegielski-Sulzer
6AL25/30 diesels rotating two controllable pitch propellers. It also has two 143
hp mSS5e electric motors, and three 192 kW diesel generators. The vessel has a
crew of 27 and it can carry a research team of 9 persons.
survey vesses of this project in two modifications served on all fleets of the
USSR and later - the Russian Federation. In total, 23 vessels of this type were
built for the Navy.
Hydrographic Survey Vessel GS-398 laid down at the
Stocznia Polnocna Shipyard, Gdansk, Poland (yard No.872/13), launched 09 February
1980, commissioned 10 June 1980 and was assigned to the Black Sea Fleet.
1981, the vessel was upgraded to a trial ship and renamed to OS-265. It was part
of the 184th marine research station, based on Balaclava, Crimea, was intended
for transportation of fighting dolphins.
From 01 January 1996, the vessel
was reclassified to military transport, and renamed to VTR-75.
Tuapse Shipyard upgraded the vessel according to Project 872E (Ecological Monitoring
Vessel). The conversion project was developed at Vympel Design Bureau. On 24 April
2005, a acceptance certificate was signed with rename to Petr Gradov.
ship regularly monitors water area around the fleets moorage sites, coastal
assets, and military units of Southern Military District. In 2011, Petr Gradov
has carried out over 20 control raids around BSF basing sites, including those
near Caucasus Mountains. That made possible to conduct ecological monitoring of
aquatic environment with mapping of pollution zones, provide ecological maintenance
to the fleets combat training activities, and collect data for environmental
audits according to Russias international commitments.
Now in service.
