A jackup drill rig or a self elevating offshore vessel is a form of movable offshore platform that consists of a floating hull with an arrangement of number of changeable legs, competent of lifting its hull above the sea level.

The floating hull facilitates shipping of the drilling rig and the entire necessary system to a required position. On the desired location the hull is lifted up to the required elevation above the water level by the support of legs standing on the ocean floor.

The legs of jackup drill rigs may be so constructed that it can pierce the ocean floor, may be built-in with inflated segments or footholds, or may be joined to an underneath mat. Usually jackup rigs do not have its own engine and depends on tug boats for tow or on heavy pick up ships for shipping.

Jackup drill rigs are used as research drilling platforms, for offshore oil and gas platforms and offshore wind farm maintenance platforms. Offshore Jackup rigs have been widely famous and many different kinds of offshore mobile rig forms are in continuation.

The Jackup drill rigs are so called since they are self-elevating with three, four, six and even eight variable legs that can be stretched out i.e, jacked over or under the hull.

The Jackup oil rigs are towed by tug boats or transported by heavy lift ships or self propelled to the location with the hull floating on the sea surface and the legs stretching out on top of the hull.

The hull is in fact a waterproof barge that sails on the sea level. When the Jackup drill rig arrives the project location, the rig crew jacks the legs below through the

water onto the sea bed with mat sustaining jackups or penetrates into the sea bed. This secures the Jackup rig and retains the hull suitably over the sea water.
