Semi Submersible Drilling Rig 3D model

A Semi Submersible Drilling Rig is designed for offshore drilling in deep waters, they are partially submerged in water during drilling operations and are normally moored to the sea bed by anchors.They are technically advanced drilling units which are designed to accommodate heavy machinery and drilling equipment and are supported by columns for support and stability in the ocean, the pontoons have sufficient buoyancy to float the structure, but sufficient weight to keep the structure upright.

Semi-submersible platforms can be moved from place to place and can be ballasted up or down by altering the amount of flooding in buoyancy tanks. They are generally anchored by combinations of chain or wire rope during drilling and/or production operations, though they can also be kept in place by the use of dynamic positioning.

Please note: in the preview image showing the rig at sea ONLY the 3d for the Semi-Sub model is included, there is NO ocean surface or supply ship.
