A method for controlling movement of a cantilever structure of an offshore platform, such as a jack-up platform or a self-elevating vessel, the cantilever structure being elongate in a longitudinal direction and coupled to a hull of the platform via supports (11A-D) and skidding guides (9,10), the supports (11A-D) and the skidding guides (9,10) being arranged for guided skidding displacement of the supports (11A-D) along associated ones of the skidding guides (9,10), the method comprising: - reading current position data representing a current position of an item on or of the cantilever structure; - reading target position data representing a target position of said item; - reading position dependent support load data associating support loads to at least a plurality of positions of said item; - determining, from the current position data and the target position data, displacements required for displacing said item to said target position including longitudinal skidding displacement of first ones of the supports (11A-D) of the cantilever in said longitudinal direction and transverse skidding displacement of second ones the supports (11A-D) of the cantilever in a horizontal direction transverse to said longitudinal direction; - determining from said position dependent support load data support loads during said determined longitudinal skidding displacement; - determining a low wear trajectory of said item from said current position to said target position in which, if and until a sum of support loads or a highest support load decreases during said longitudinal skidding displacement towards the target position, said longitudinal skidding displacement towards the target position precedes said transverse skidding displacement and, if a sum of support loads or a highest support load increases during said longitudinal skidding displacement towards the target position, said transverse skidding displacement towards the target position precedes said longitudinal skidding displacement; and - controlling movement of the cantilever structure to follow said low wear trajectory. - reading current position data representing a current position of an item on or of the cantilever structure; - reading target position data representing a target position of said item; - reading position dependent support load data associating support loads to at least a plurality of positions of said item; - determining, from the current position data and the target position data, displacements required for displacing said item to said target position including longitudinal skidding displacement of first ones of the supports (11A-D) of the cantilever in said longitudinal direction and transverse skidding displacement of second ones the supports (11A-D) of the cantilever in a horizontal direction transverse to said longitudinal direction; - determining from said position dependent support load data support loads during said determined longitudinal skidding displacement; - determining a low wear trajectory of said item from said current position to said target position in which, if and until a sum of support loads or a highest support load decreases during said longitudinal skidding displacement towards the target position, said longitudinal skidding displacement towards the target position precedes said transverse skidding displacement and, if a sum of support loads or a highest support load increases during said longitudinal skidding displacement towards the target position, said transverse skidding displacement towards the target position precedes said longitudinal skidding displacement; and - controlling movement of the cantilever structure to follow said low wear trajectory.
