"Spasatel Kavdeikin" towed pipelaying barge "Defender" form Murmansdk to Sravanger


Due to information from site of FBE "Marine Salvage Service of RosMorRechFlot", MPSV07 multifunction 4 MW salvage arctic vessel (MSV) "Spasatel Kavdeikin" (included in the Northern Branch of FBE "Marine Salvage Service of RosMorRechFlot") took part in the towage operation of pipelaying barge "Defender" (JSE Mezhregiontruboprovodstroy is a shipowner).
 
At the first step pipelaying barge "Defender" was towed from the port of Murmansk to the port of Stavanger during 23.03 - 05.04.2015.
 
Barge was towed back at the second step; towage operation was completed successfully on 19.05.2015.
 
"Spasatel Kavdeikin" is a unique multifunctional salvage vessel by her equipment and available technology; she was built in 2013 by Nevsky Shipyard (Russia) by 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 "State Marine Emergency Salvage, Rescue and Pollution Prevention Coordination Service of the Russian Federation" (FBE SMPCSA).
 
3 vessels of the "Spasatel Kavdeikin" type are the biggest and the most significant vessels nowadays built at the expense of funds of the Federal Target Program for the Development of transport system of Russia for 2010-2015 years. The fourth vessel is being built now.
 
Vessel's project was designed by Marine Engineering Bureau.
 
Multifunction Arctic salvage vessels of MPSV07 prj. are to carry out operations as follows:
 
• patrolling and emergency salvage duty at the navigation regions, fishing regions, oil and gas marine recovery regions;
• give 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;
• give 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 (LARN);
• 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.
 
MPSV07 vessels have unrestricted navigation area, including sailing by the Northern Marine Way. 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 Marine Way" have been fully taken into account during the designing and construction. For example, all the fuel, oil 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 vessel of MPSV07 project are as follows:
 
Length overall is about 73.00 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 experimental pools (deep-sea and ice ones). Full-circle rudder propellers were adopted as the movement and manoeuvre facilities of vessels "Spasatel Zaborschikov". Propellers with diameter of 2600 mm were made of stainless steel. Drive of each FRP is provided by the propeller motor with capacity of 2265 kW. Rudder propellers provide the speed of the vessel not less than 15 knots and bollard pull of about 75 tons.
 
The maximum speed achieved during trials was of 15.6 knots.
 
The hull and rudder-propeller complex of the vessel of MPSV07 project is designed for ice class Arc 5, also the possibility of vessel 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.
