A Semi-Submersible Rig or a "Semi-Sub" or a "Semi" or a "Floater" is a drilling rig that is used to drill wells in water depths inaccessible to jack-up rigs (water depths greater than 400 ft). Semi-submersible rigs are buoyant and, unlike jack-up rigs which rest on the seabed, float during drilling operations. These semi-submersible platforms are moored over the drilling site and are normally provided with a central opening through which the drilling rig is operated. Semi-submersible rigs make stable platforms for seeking and drilling for offshore oil and gas. The need for anchorless or thruster assisted Maersk Drilling's four semi-submersibles are capable of operating in ultra deepwater of up to 3,000 metres and can maintain their station either in dynamic positioning (DP) mode or with a pre-laid mooring system. Their superior offline capabilities support safe and efficient operations to the benefit of the A semi-submersible drilling rig or a semisub is a type of floating drilling rig that is partly submerged to provide station keeping and stability. It comprises a submerged hull typically pontoon-type columns joint together with the drilling platform by large tubulars. The main purpose of the semisub is to avoid Drilling Semi-Submersible. Semisubmersible rigs are floating offshore drilling units with pontoons and columns that, when flooded with water, cause the unit to A semi-submersible drilling vessel for offshore drilling of the catamaran type has two substantially horizontal, parallel and spaced, elongated Category:Semi-submersible drilling rigs.
