More Information
Summary:For controlling movement of a cantilever of an offshore platform, displacements required for displacing an item to a target position including longitudinal skidding displacement and transverse skidding displacement of the cantilever of the cantilever are determined from current position data and target position data. From position dependent support load data support loads during the longitudinal skidding displacement are determined. If and until a sum of support loads or a highest support load decreases during the longitudinal skidding displacement towards the target position, the longitudinal skidding displacement precedes the transverse skidding displacement. If a sum of support loads or a highest support load increases during the longitudinal skidding displacement towards the target position, the transverse skidding displacement towards the target position precedes the longitudinal skidding displacement.
