When the weather permits, the submarine will be raised to just below the pontoon. The lifting will be precisely controlled, centimeter by centimeter. The force on each bundle of cables can be set individually to minimize the tension on the Kursk's hull. The strand jacks will each pull bundles of 54 thinner cables (strands) by means of two telescopic cylinders. The impact of the swell of the sea will be reduced by heave compensators so that the force exerted on the attachment points on the Kursk is constant. Computers installed with comprehensive back-up systems will control the entire lifting process.
