Sea diving vessel "Rostov Velikiy" of SDS08 project took part in salvage operation of motorship "Tikhon Semushkin" in Avachinskaya Gulf


According to report of Minister of Special Programs and Cossacks Matters of Kamchatka Region Sergey Khabarov on May 04, 2012, specialists of Sakhalin basin search-and-rescue administration (SakhBSRA) pumped out about 100 cub. m. of oily water from tanks of emergency vessel "Tikhon Semushkin".
 
From April 11, 2012 SakhBSRA sea diving vessel "Rostov Velikiy" of SDS08 project took part in salvage operation of motorship "Tikhon Semushkin" (water exhaust works from engine room, diving works, providing of towage).
 
Mv "Tikhon Semushkin" stood abandoned near berth in Avacha settlement about three years because of economic entities dispute according to information from administration press-service of Kamchatka Region. In April 2012 vandals had unscrewed valves (made from nonferrous metal) from main engine cooling system and water gushed into engine room. Vessel's stern went aground, dangers of vessel capsize and fuel spill had appeared. Rescuers succeeded to make vessel airtight and towed her to safe place.
 
"At this time vessel is steady moored at SakhBSRA berth. Oily water pumped out from vessel port side tanks. There are no dangers of vessel capsize and fuel spill", - said Sergey Khabarov. According to his words, engine room and other masut polluted placements are treated by sorbent. Defueling works from "Tikhon Semushkin" still in progress.
 
Sea diving vessel "Rostov Velikiy" (building No is of 202) of SDS08 project was built in 2011 at Yaroslavl Shipyard (Private Joint Stock Management Company "VP FINSUDPROM") for FSUC State Maritime Salvage Department under the order of Federal Agency of the Maritime and River Transport of RF Ministry of Transport.
 
Design of "Rostov Velikiy" vessel was carried out by the Marine Engineering Bureau.
 
Project considerably differs from existing operated 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 (OSR) functions if boom and skimmer are mounted.
 
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 propulsion 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.
 
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 OSR operations. Such combination of functions is unique for vessel with length of 38 m only.
 
Keel of the lead vessel of SDS08 project "Stolniy Grad Yaroslavl" (building No is of 201) was laid down on August 28, 2009. Vessel was launched on August 12, 2010 and put into operation on October 25, 2010.
Keel of the second vessel in the series "Rostov Velikiy" (building No is of 202) was laid down on March 9, 2010. She was launched on April 21, 2011 and put into operation on May 30, 2011.
Keel of the third vessel in the series "Uglich" (building No is of 203) was laid down on March 16, 2010. She was launched on May 24, 2011 and put into operation on August 7, 2011.
