Described is a lifting system for taking up an elongate object from a deck of a vessel. The lifting system has a crane arm which is connected to the deck and from which is suspended a take-up frame to which the elongate object can be attached. Also present is a winch setup and control lines connected thereto and configured to control the movement of the elongate object when this object is lifted off the deck. The control lines run from the take-up frame to the winch setup. The winch setup forms part of a support structure which extends from the deck to a height and is intended to be able to absorb the forces acting on the object while it is being lifted off the deck. Also described is a method for taking up an elongate object from a deck of a vessel.
A vessel comprising a lifting system for taking up an elongate object from a deck of the vessel, comprising a crane arm which is connected to the deck and from which is suspended a take-up frame to which the elongate object can be attached, and further a winch setup and control lines connected thereto and configured to control the movement of the elongate object when this object is lifted off the deck, wherein the control lines run from the take-up frame to a pulley setup and from there to the winch setup, which pulley setup and winch setup are provided on a support structure, which differs from the crane arm, extends from the deck of the vessel to a height and is configured to be able to absorb the forces acting on the object while the object is being lifted off the deck, and wherein the pulley setup is movable relative to the support structure in a height direction.
