A cyclone separator intended to separate a fluid by hydraulic forces.

A system that provides lubricant to rotating or moving items.

A physical object that contains a chamber with several openings.

A physical object that is a long tube or hollow body intended for conduction of liquid, gaseous or finely divided solid materials, or used for structural purposes.

A fluid conductor that consists of pipe, possibly also including pumps, valves, and control devices, intended for conveying liquids, gases, or finely divided solids.

A vertical vessel intended to enable chemical reactions or physical processes utilising differences in density of fluids and/or forced flow of fluid.

A physical object that adds or removes mechanical energy to a fluid, either constantly or periodically.

A positive displacement pump which contains a displacing element intended to be moved in a reciprocating movement to exert pressure on a fluid, typically moving within a cylindrical space.

A physical object that is a vertical or near vertical pipe for the upward flow of liquid or gas.

A positive displacement pump that consists of a chamber containing gears, cams, screws, vanes, plungers or similar elements actuated by relative rotation of the drive shaft or casing and which has no separate inlet and outlet valves.

A 'well drilling system' and an 'artefact' in which the torque is transferred to the drill string using rotary table and kelly.

A tool that can be used to install or remove machines or equipment.

A distillation column intended to clean gas by washing the gas flow with water or with another liquid entering at the top of the vessel and sprayed in the gas. Typically to remove dust and small particles.

A 'device' intended to separate different types of substances.

A physical object that consists of wedge-shaped pieces of metal loosely joined together and fitted into a bushing to support a string of pipe. The slips have gripping elements to prevent the pipe from slipping down the drilling hole.

A column which transforms a material from an unstable state to a more stable state; for fluids typically by removing volatile components from a mixture.

A physical object that is intended to mix fluid by means of diverging the flow with static obstacles or by increasing locally the velocity.

A distillation column intended to remove light components from a fluid.

Flexible pipe, wholly or in part, resting on the seafloor or buried below the seafloor, and used in a static application.

An artefact for connecting a well or a manifold to a subsea flowline.

An artefact joining two parts so that one or both can pivot freely (as on a bolt or pin).

A distillation column intended to withstand outside pressure.

A physical object that consists of an electric motor and controller that is used to adjust the motor's operating speed.
