Developed for both land and offshore drilling rigs, AC traction drilling motors – as this one from GE – come in both horizontal and vertical configurations. The features include: heavy-duty frames; form-wound stator windings; high-strength rotor assemblies; and a low-inertia rotor.

The fluid reservoir unit is a mixing system that pumps the proper mixture of hydraulic fluid concentrate, water and antifreeze from storage reservoirs into the mixed control fluid reservoir, providing the necessary lubricity and freeze protection to maintain reliable BOP stack operations and long service life.

A blowout preventer (BOP) is a large, specialized valve used to seal, control and monitor oil and gas wells. Blowout preventers were developed to cope with extreme erratic pressures and uncontrolled flow emanating from a well reservoir during drilling. BOPs are used on land rigs, offshore rigs and subsea.

A top drive is a mechanical device on a drilling rig that provides clockwise torque to the drill string to facilitate the process of drilling a borehole. It is located at the swivel place and allows a vertical movement up and down the derrick.

A drawworks is the primary hoisting machinery that is a component of a rotary drilling rig. Its main function is to provide a means of raising and lowering the traveling blocks.

The Lower Marine Riser Package (LMRP) is a mechanical device to protect an oil well located underwater (subsea) and is used during an oil well intervention.

A mud pump is a reciprocating piston/plunger device used to circulate drilling fluid (mud) on a drilling rig under high pressure down the drill string and back up the annulus. It is an important part of the oil well drilling equipment.

A semi-submersible is a term used for specialised marine vessel such as offshore drilling rigs, safety vessels, oil production platforms, and heavy lift cranes. They are designed with good stability and seakeeping characteristics.

A Jackup rig is a type of mobile platform that consists of a buoyant hull fitted with a number of movable legs, capable of raising its hull over the surface of the sea. The buoyant hull enables transportation of the unit and all attached machinery to a desired location.

A drillship is a vessel designed for use in exploratory offshore drilling of new oil and gas wells or for scientific drilling purposes. The vessels are used in ultra-deepwater applications, equipped with the latest and most advanced dynamic positioning systems.
