DP3 SEMISUBMERSIBLE DRILLING RIG FOR SALE
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 large surge movements from wave.
SINGATAC OFFSHORE CENTRE SemiSubmersible Rig "Island Innovator"
A Semi-Submersible Rig, often known as a "Semi-Sub," "Semi," or "Floater," is a drilling rig used to drill wells in water depths unreachable to jack-up rigs with water depths greater than 400 ft. Additionally, Semi-submersible drilling rigs are buoyant, unlike jack-up rigs that float during drilling operations. Table of contents

The Hercules is a sixth generation deepwater and harsh environment semi-submersible. It is a state-of-the-art tall derrick, dynamic-positioned unit of GVA 7500 design and is equipped with a full conventional mooring spread for operations in water depths of 100 to 500 metres. .
China's most advanced deepwater semisubmersible drilling rig delivered
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.

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.
