Abstract
A jacking system () is described for a leg () of a jack-up platform (). The jacking system comprises at least three independent yokes (-). Each independent yoke is connected to a jack-up structure by at least one vertically arranged double acting actuator (-') and is equipped with a leg engaging mechanism such as a horizontally arranged movable locking pin (-), which is configured to engage or to disengage with a hole of the jack-up leg, in order to transfer a load (L) from the jack-up platform () to the leg (), including a controller configured to operate the yokes (-) in a way that the leg () is moved by all the at least three yokes (-) in an alternating mode, such that at any moment in time during operation all but one of the at least three yokes (-) take the load (L) via the associated engaging mechanism, while the remaining yoke of the at least three yokes (-) makes a return stroke with its engagement mechanism in a disengaged position.
