Submersible Rig

Petroleum Equipment

A submersible rig is a mobile drilling rig used in the petroleum industry for offshore drilling in shallow waters. A submersible rig is very similar to a jack-up in that the rig is designed to make contact with the ocean or lake floor. It contains a platform with two hulls positioned one on top of the other. The upper hull serves as the living quarters for the crew and houses the drilling platform. The function of the lower hull is very similar to that of the outer hull of a submarine. When the rig gets relocated, the lower hull is filled with air to make the whole rig bouyant. Once relocated to a new drill site, the air is removed from the lower hull and the rig automatically submerges to the bottom of the sea or lake floor.[1]
