A pressure vessel intended for sending a pig into a pipeline.

A pressure vessel intended for receiving a pig from a pipeline.

A facility on a pipeline for inserting and retrieving a scraper or pig.

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

A positive displacement compressor in which forced reduction of gas volume takes place by the movement of a displacing element in a cylinder or enclosure.

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 rigid vertical or near vertical pipe for the flow of liquid or gas between the seabed and the surface.

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

A positive displacement compressor in which compression displacement is effected by the positive action of rotating elements.

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 'device' intended to separate different types of substances.

A catcher intended to catch and separate liquid slugs from a fluid stream.

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 thermodynamic turbine in which steam is made to do work by expanding so as to create kinetic energy by acting on moving blades attached to a disc or drum.

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

Is an artefact intended to collect a heavy phase by making use of gravity.

A vessel intended to contain fluid for storage. Typically a receiving or collecting function for further distribution. Typically with a vertical and cylindrical or square shape and a flat or conical bottom.

A physical object that is intended to rotate within a fluid and to transform energy within a fluid into mechanical power.
