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.

By 1958, the number of submersible drilling rigs had increased to around 30. In 1961, Shell Oil successfully converted an existing submersible rig Blue Water Rig No.1 into the first semi submersible drilling unit for operation in the Gulf of Mexico when it was found to have good stability and motions whilst being towed at a partial draught.

A Semi- Submersible Rig, also called a Semi-Sub, Semi or Floater, is used to explore and extract oil and gas from beneath the ocean floor. It is used for drilling wells in water depths that are not accessible to jack-up rigs. Semi-Subs are buoyant, unlike the jack-up rigs that rest on the seabed while the latter float.
