Bottom-supported offshore drilling rig Definition


Bottom-supported offshore drilling rig:

A type of mobile offshore drilling unit that has a part of its structure in contact with the seafloor when it is on site and drilling a well.

The remainder of the rig is supported above the water.

The rig can float, however, allowing it to be moved from one drill site to another.

Bottom-supported units include submersible rigs and jackup rigs.
