PSK-1412 boat is refitted at Murmansk shipyard

20.10.2009
The boat PSK-1412 was refitted at JSC Murmansk Naval Shipyard by the project of JSC KB Vympel design bureau under development work "Schupaltsa-1" ("Ecological monitoring and radiation control system"). The project provides refitting of PSK-1412 at Northern Fleet Shipyard 33 with installation of the shipboard system.

Chief Designer is L.S. Makarov.

The Poland-made former ambulance boat of Project SK-620/II was chosen as an object of refit.

The boat has following characteristics:

- length overall is 33.0 m;
- total displacement is 260.0 t;
- maximum speed is up to 11 knots.

Ecological equipment includes:
- Grebeshok water environment monitoring system;
- oil spillage search and clearing system, including boom boat VV-100 and 560 meters of floating booms BPP-600;
- unmanned remote-controlled submersible FISh-106.

Ecological equipment mounted on the boat enables to perform following tasks:

– acquisition, processing and display of information taken by all measuring instruments of Grebeshok system; arrangement, analysis and storage of information about environmental situation in littoral zone, at inner and outer harbors, in basing and deployment sites of Northern Fleet objects;
– space-time information processing displayed on electronic charts, environmental history control comparing incoming data with results stored in database;
– making hydro-chemical express analysis of samples taken on move by continuous sampling system at subsurface layer (0.5-1.0 m), or one sample taken on drift at deep layer (down to 100 m) upon 8 controlled factors;
– radiation control, including:

a) detection of gamma-emitting radionuclides contained in water and change of their volume activity at specified levels from surface to seabed layer (200 m) on drift;
b) power measurement of gamma emission exposition dose in surface air layer;
c) volume activity measurement of gamma- and beta-emitting radionuclides in water samples taken at subsurface and seabed water layers and also from bottom soil;

– automatic detection of oil spills at water surface with the thickness of 1.0 micron per meter any time of the day at sea disturbance up to rate 2; measurement of its thickness (within the range of 0.2-160 micron per meter inc) in samples taken from surface layer;
– video monitoring and recording of underwater situation (at depths down to 150 m) by deep-sea submersible; water surface panorama and coastline - by digital camera;
– bottom profile logging, detecting layers with abnormal sonic scattering characteristics, localization of drowned objects;
– measurement of basic chemico-physical parameters of water at soundings and sea-coast transitional area by small environmental boat;
– measurement of pollutant concentration in surface air layer while conducting potentially dangerous works or occurrence of contingencies;
– measurement of mass concentration of chrome, iron, bismuth, manganese, cobalt, nickel, lead, zinc and mercury in collected water samples;
– measurement of mass concentration of acid-soluble, water-soluble and moving forms of metals in samples of soil and bottom;
– measurement of concentration of oil-products, anionic surfactants, cationic surfactants and formaldehyde in natural pure water and waste water;
– participation in containment of accidental oil spillage;
– inspection of ships' vitalses, waterworks and sea bottom in responsibility area of Northern Fleet;
– ecological control of engineering works in aquatic areas.

The boat is equipped with full range of advanced technical facilities providing comfortable conditions for safe and quality task performance.

Acceptance Certificate commissioning the ecological boat in the Navy was signed on Oct 6, 2009.

That job is another successful step of Vympel design bureau in creation of vessels for ecological monitoring and containment of accidentally spilled aggressive agents.
