    The platform of the lift moves along the rack railway, with the track gauge of 9 m. The movement is carried out by means of electric drive. In order to load the ship lift, the platform is lowered below the water level, at which point the ship then enters the lift, and the platform begins to move up the overpass. The ships are transported afloat.

    The vessel is essentially a large platform supported by eight columns (four on each side), with one pontoon per side. Typical SSCVs use larger columns under the cranes to provide support, which can lead to severe pitching in rough seas; SSCV Sleipnir uses columns that are symmetrical fore and aft for calmer motions under higher sea states.
