1. A hoisting arrangement for hoisting a load, comprising:
a gripper attachment arranged to be connected to the load, comprising a set of cable attachment points arranged as a first polygon;
a vessel attachment module configured for attachment to a vessel, comprising a plurality of cable guide elements arranged as a second polygon;
a plurality of cables spanned between the cable attachment points and the cable guide elements, and
a control system for controlling a position and/or orientation of the gripper attachment within a work space by controlling a spanned length of at least two cables of the plurality of cables between the cable attachment points and the cable guide elements;
wherein the vessel attachment module further comprises two lateral arms and a center arm arranged to be connected to a boom of a crane connected to the vessel, said crane including a crane base configured for interconnecting the boom and the vessel,
said lateral arms project on opposite sides from a sagittal plane of the boom, such that first and second subsets of cable guide elements provided on said lateral arms are located within or rearwards relative to a sagittal cross-sectional periphery of the boom
said center arm extends along the sagittal plane of the boom, such that a third subset of the cable guide elements provided on said center arm is located forwards relative to the sagittal cross-sectional periphery of the boom; and
the center arm is at least partially oriented at an angle relative to a plane spanned by the lateral arms.
