Jack-Up Drilling Rig

A jack-up rig is a mobile offshore drilling unit. The purpose of the rig is to drill new wells, alter existing wells, or suspend or abandon older wells. A jack-up rig has no propulsion system and must be towed to location. The legs of a jack-up rig can be fully lifted while it is towed and lowered when operating so the hull is out of the water. A jack-up rig always has a 500 metre safety zone.
