STRUCTURE ANTI-TORSION, NAVIRE ET PROCÉDÉ POUR FAIRE DESCENDRE UN OBJET DANS UNE ÉTENDUE D'EAU

摘要

The invention relates to a method for lowering an object in a water body from a vessel floating on the water body, the vessel comprising first hoisting means with second hoisting means arranged on or near the vessel, with at least a first anti-twist frame (ATF) being connected to a lower end of a first hoisting cable of the first hoisting means, the object being attached to the lower end of the first hoisting cable, below the ATF. The method allows for adjusting the vessel's heading prior to carrying out the method, allowing the vessel to remain substantially aligned with the wind/wave direction, and at the same time preventing the first hoisting cable from being subjected to excessive twist.
