Abstract
A method for determining a leg load acting on a support leg that can be lowered by a rack-and-pinion drive of a jack-up vessel has a supporting structure for at least one gear unit of the rack-and-pinion drive. At least one strain gauge is arranged on the supporting structure to detect the strain in the supporting structure caused by the leg load. Any strain in the supporting structure is detected with the at least one strain gauge and the leg load is determined from the detected strain. A lifting device for a lowerable support leg of a jack-up vessel with a measuring device for determining a leg load acting on the support leg is also described.
