The damaged bow will first be cutoff before the Kursk is raised.
Cutting of the bow
The cutting chain saw will bepulled backwards and forwardsto cut through the Kursk.
The cutting chain is made up of cylindrical drums covered with an abrasive layer.

Lifting unit
Each cable is made up of 54 steelstrands. The lifting is comparableto rope climbing. The hydrauliccylinder pulls up the bundle byclasping alternatively the top andthe bottom of the cable. 26 ofthese lifting units are anchoredto the pontoon.

MurmanskThe pontoon will be positionedabove the Kursk by eight linesanchored to the seabed.
The Kursk sank with 118 crew onboard in the Barents Sea on August 12, 2000. In October of that year, Norwegian and Russian divers working from the Norwegian salvage vessel Regalia recovered 12 bodies from the forward section of the submarine. Mammoet and Smit International will use eight vessels and more than 100 people to raise the Kursk.
Holes will then be drilled in the hull and divers will attach cables using plugs in the vessel’s side.
The vessel will then be lifted to just under the pontoon. A computer will closely monitor the tension on the cables to regulate the spread of the load during the lifting.
Suspended under the pontoon, the submarine will then be sailed to a dry dock in Murmansk.
The damaged head of the submarine will first be cut off using a cutting chain. It will remain on the seabed and salvaged later by the Russians.
Salvaging will start at the end of June and must be completed by the end of September. The operation’s success will be determined by the weather.
The Dutch company Mammoet in cooperation with Smit International is going to salvage the Russian nuclear submarine Kursk that sank last year. Mammoet will carry out the lifting work and Smit International all underwater work.
