FIELD: transportation.
SUBSTANCE: groups of decouplers are designed to be placed on a mooring rope connecting a floating vessel with an anchor, has a pair of rotatably connected lever elements. In the first closed position the lever elements are held by a closed shear pin. The mating slots in each lever element grasp the component of the mooring rope, such as the pin of the rigging staple, when the lever elements are closed. The cylindrical centering device is placed in the mooring rope between the decoupler and the vessel and rests against the lever elements. The force applied to the centering device, either by pulling it into the surface fairlead sheave or a similar device, or by the underwater pull-out device, forces the lever elements apart, breaking the shear pin and disconnecting the device, thus disconnecting the mooring rope.
EFFECT: speed of the vessel's displacement from the ground and the reliability of detaching the mooring ropes from the anchor.
