Submersible Drilling Rig Guide In Oil & Gas
Submersible Rigs are a mobile drilling units that have a bottom support. This idea came from making a barge sit on the bottom of Louisiana swamps with drilling platforms welded on top. Thus came the first submersible, a totally submerged, conventional-sized barge. It also has columns high enough to support a platform at a safe above-water distance. Pontoons on either side of the barge provided both stability and displacement control.
