Marine diving vessel "Stolniy Grad Yaroslavl" (SDS08 prj.) is taking part in towage of drilling platform for oilfield named for V. Filanovskiy

According to the press-service of FBE "State Marine Emergency Salvage, Rescue and Pollution Prevention Coordination Service of the Russian Federation" (SMPCSA), marine diving vessel "Stolniy Grad Yaroslavl" (SDS08 prj.) is taking part in towing operation of construction's elements of drilling platform for oilfield named for V. Filanovskiy since 24.06.2014 to 08.08.2014. Total towage distance from Astrakhan port to oilfield through Volgo-Caspian Canal is 180 km. In consideration of towing operation's uniqueness, it is being carried out in day-time. Vessels traffic through Volgo-Caspian Canal is stopped to provide safety of the towage convoy.
 
A flagship of diving fleet of Caspian branch of FBE SMPCSA, SDS08 marine diving vessel "Stolniy Grad Yaroslavl" moves in front of towage convoy and ensures safety of difficult towage and installation of platform's blocks at oilfield named for V. Filanovskiy.
 
Work was implemented for Contract's carrying out of diving ensuring due to transportation and installation of objects at oilfield named for V. Filanovskogo at Caspian Sea, concluded between FBC "Gosmorspasslyzba Rossii" and SAIPEM Italian Company.
 
It is planned to use diving vessel "Stolniy Grad Yaroslavl" for 4 similar towing operations until end of 2014.
 
Marine diving vessel "Stolniy Grad Yaroslavl" (SDS08 prj.) was built at Yaroslavl Shipyard in 2010 due to order of FSUC "State Customer Management of Maritime Transport Development Programs" of the Federal Agency of Maritime and River Transport of the Russian Federation.
 
Class project was designed by Marine Engineering Bureau; working and technological documentation was prepared by Design Bureau Petrobalt.
 
SDS08 prj. marine diving vessel has Ice 2 class, inclined stem and transom aft end, long forecastle, deckhouse located fore. Vessel also has engine room located aft, diesel main engines, two controllable-pitch propellers and bow thruster. Her principal dimensions are as follows:
 
• Length overall - 38.35 m.
• 
• Length between perpendiculars - 36.35 m;
• Breadth overall - about 7,92 m;
• Breadth (due waterline) - 7.70 m;
• Design draught - 2.35 m;
• Full speed - 12 kn;
• Economical speed - 8 kn;
• Main engines capacity - 2 x 442 kWt;
• Autonomy - 5 days.
 
Russian Maritime Registry of Shipping class is of KM Ice 2 R2 AUT3-C OMBO SDS>100.
 
Project considerably differs from existing similar vessels:
 
1. Diving equipment, mounted on vessel, allows to carry out diving and underwater works on depth till 100 m. There are no analogues of such equipment at existing vessels that are operated by State Maritime Salvage Department of RF.
2. Vessel can carry out fire extinguishing on other vessels and floating objects using two mechanical-foam stream nozzles.
3. Vessel is equipped by tug winch that allows to carry out tug functions.
4. Vessel will provide oil spill response functions if boom and skimmer are placed onboard.
5. Vessel's characteristics and special equipment provide carrying out of diving salvage operations during sea state up to 3, and vessel can sail to the salvage place during waves' height of 7 m.
6. 2 main high-speed engines with capacity of 442 kWt each provide required vessel's running qualities, work to the variable-pitch propellers. Bow thruster with capacity of 120 kWt is mounted for vessel's keeping at place of operational works.
7. Up-to-date remote-controlled underwater apparatus allow to inspect of a sea-bottom, underwater part of ships' hull and rudder propellers of vessels, underwater part of waterside structures on depth till 100 m.
8. Equipment for underwater welding on depth till 25 m and underwater cutting on depth till 100 m is used for salvage operations, repair of underwater part of vessels, repair of hydraulic structures, carrying out of rescue operations. In addition, cargo lifting equipment allows to lift objects of weight till 2.0 t from depth till 100 m.
9. Vessel carries out water pumping from wrecking vessel's compartments and also pontoon air blow during participation into re-floating.
 
Diving equipment consists of:
 
• pressure chamber for 4 divers;
• diving half-cone with control board;
• diving equipment with SUPERLITE helmet and DESCO ventilate helmet;
• diving equipment of universal "dry" type;
• divers' water-heater facilities;
• communication facilities;
• underwater illumination facilities;
• underwater television;
• underwater welding/cutting;
• hydraulic tools;
• pumping facilities;
• soil man facilities;
• remote-controlled underwater apparatus;
• diving ladder.
 
Thereby, unique combination of equipment mounted on vessel, and also high-powered power plant allow to carry out almost any specialized works related to diving-technical works on depth till 100 m. In addition vessel can carry out fire extinguishing on other vessels using two mechanical-foam stream nozzles with capacity of 180 cub. m per hour and carry out tug functions (ground-mooring-tug winch with force of 7 tons is mounted aft), pump water out from compartment of wrecking vessel, participate into oil spill operations. Such combination of functions is unique for vessel with length of 38 m only.
