4 MW multifunctional MPSV07 rescue vessel (MASS) of Arctic navigation "Spasatel Karev" got off to vessel's help in the area of Vilkitsky Island

According to the website of the Marine Rescue Service, 4 MW multifunctional MPSV07 rescue vessel (MASS) of Arctic navigation "Spasatel Karev" celebrated New Year holidays at sea.
4 MW multifunctional MPSV07 rescue vessel (MASS) of Arctic navigation "Spasatel Karev" got off to help in the area of Vilkitsky Island to the vessel "Sparta III", which was in ice drift due to a malfunction of the steering gear.
"Spasatel Karev" is an unique multifunctional rescue vessel by her equipment and available technology; she was built at Russian shipyard due to the order of FSUC "State Customer Management of Maritime Transport Development Programs" of the Federal Agency of Maritime and River Transport of the Russian Federation. Vessel was built in behalf of Marine Rescue Service of RosMorRechFlot.
MPSV07 prj. was designed by Marine Engineering Bureau.
Multifunction salvage vessel of MPSV07 prj. is to carry out operations as follows:
• patrolling and emergency rescue duty at the navigation regions, fishing regions, oil and gas marine recovery regions;
• provide technical support and help in the regions dangerous for navigation and marine products catching, servicing of terminal transport operations;
• search and help vessels in distress;
• search, salvage, evacuation operations for people, rendering medical aid for people;
• taking emergency vessels off groundings and reefs, pumping out vessels' flooded spaces;
• towage of emergency vessels and objects to the place of refuge, also fulfillment marine towage of vessels and floating objects, including ice towages;
• fulfillment of marine salvage operations, including in ice conditions;
• provide assistance in fire combating on floating objects and coastal ones accessible from seaside;
• rear and technical service, including underwater diving works at the depth till 60 m;
• fire-extinguishing of burning oil on water surface, elimination of marine oil spills, including oils with flashpoint less than 60°C;
• survey and cleaning underwater hull part of vessels, floating and coastal objects;
• investigation of sea floor and damaged objects when depth is less than 1000 m.
Vessels of MPSV07 project have unrestricted navigation area, including sailing through the Northern Sea Route. For this purpose, the requirements of the Rules of RMRS, existing international conventions and "Requirements for construction and equipment of vessels sailing by the Northern Sea Route" have been fully taken into account during the designing and construction. For example, all the fuels, oils and other tanks with liquid pollutants are located in such way that the tank content doesn't contact with the outer shell.
The vessel was built due to Russian Maritime Registry of Shipping class notation of KM Arc 5 AUT1-ICS OMBO FF3WS DYNPOS-2 EPP Salvage ship.
Principal dimensions of the MPSV07 vessel are as follows:
Length overall is about 73.00 m;
Length between perpendiculars is 64.40 m;
Breadth overall is about 16.60 m;
Breadth (due waterline) is 15.50 m;
Design draught is 4.50 m;
Working draughts are 4.2-5.1 m.
The MPSV07 hull's form was created using the methods of computational fluid dynamics (CFD modeling) with carrying out of the subsequent test model trials in towing tanks (deep-sea and ice ones). Full-turned rudder propellers (FRP) were accepted as the movement and manoeuvre units of vessels. Propellers of diameter 2600 mm are made of stainless steel. Drive of each FRP is provided by propulsion motor with capacity of 2265 kW. FRPs provide the speed of the vessel not less than 15 kn and bollard pull of about 75 t.
The maximum speed achieved during trials was of 15.6 knots.
The hull and rudder-propeller complex of the MPSV07 vessel is designed for ice class Arc 5, possibility of the vessel's operation at temperatures down to minus 40°C is provided.
Fuel stores are placed in deep-tanks in the area of ER. Tank capacity provides autonomy of the vessel for about 20 days in the mode of rescue and patrol duty.
Main diesel-electric power station consists of 4 diesel generators of alternate current of 690 V/ 50 Hz, with electric capacity of 1370 kW each.
The crew consists of 20 people; each crewmember is accommodated in a single cabin. Block-cabins consisting of office, saloon, bedroom and bathroom are provided for the captain, chief mate, chief engineer and head of the emergency party.
12 single cabins with an additional folding bed are provided for special crew accommodation (emergency party, divers and support personal for diving equipment, etc.). Also, there are 2 standby double cabins.
The accommodation of rescued people is foreseen in mess-rooms and also at additional beds at crew cabins. Also, there is 6-place hospital.
The total number of men onboard is foreseen by 101. Individual and collective life-saving appliances are provided with a 50% reserve.
Roll damping system of Hoppe Company is foreseen for improving habitability parameters.
High-speed rescue boat with a capacity of 17 people, which is capable to reach speed up to 25 kn is provided for operative emergency party delivery to an emergency vessel. This boat operation is available till the force 6 seas. The boat is equipped with fast delivered type hook for engaging with the vessel crane. Except emergency team delivery, high-speed boat can perform hydrographic, surveying and search works; the boat is equipped with hydrographic sonar and side-scan sonar for such purposes.
The equipment provided for the mass people collecting from the water on the vessels of MPSV07 prj. is as follows:
• duty boat, equipped with the net for rising people out of the water;
• Viking life raft of marine evacuation system (MES) for the people collecting and the subsequent transferring people on board by the MES slide;
• salvage appliance for rising people out of the water on board the vessel with capacity of 12 lying or 25 sitting people;
• net with the length of 7 meters for rising people out of the water on board of Dacon Rigid Scrambling Net type (on each side of the vessel);
• stretchers for rising people out of the water on board of Spenser floating stretcher type.
Two areas in the fore and aft ends of the vessel are foreseen for the receiving / transferring cargoes to (from) helicopter in order to provide emergency evacuation, as well as delivery on board of additional personal (medical team, emergency party, etc.). Special seating slings and stretchers are foreseen in the vessel's supply for rising people into the helicopter.
Towage of emergency vessels, and also fulfillment marine towage of vessels is assumed by automatic double drum towing winch with a pull of 75 tons on the lower drum and 50 m on the upper drum. Moreover, the 75 t towing hook of disk-type with the remote electro/hydraulic release is foreseen. An auxiliary 10 t winch is provided for tightening of tow wire.
