Abstract
An arrangement for raising and lowering a floating offshore platform having legs which are movable relatively to the platform. The legs, in the operating condition, are supported on the bottom of the sea, and a jacking device is blocked against downward movement whenever the floating platform is at a highest point of sea wave motion in a touched-down position of the legs. The jacking device may be in the form of rope winches, with the drive of one jacking device being switched off and the rope winch of the other jacking device being released in take-up direction, while being blockable in payout direction in touched-down position of the legs.
