Equipment used to allow drainage of foul water.

A system that provides voice and telefax communication via satellites.

A physical object intended to mechanically remove a deposit from a surface.

Is a conveyer intended to move dry, solid material from one location to another by means of a helix or screw rotating in a cylindrical conduit.

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 physical object intended to reduce or prevent the passage of fluid through an opening.

Equipment used for room separation.

A manual control switch which has more then two possible positioning states.

A valve that includes a means of operation (e.g. spring / gravity / fluid pressure / counter balance), and is not depending on an external source of energy.

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

A tank gauge that is intended to intermittently lower a displacer to measure a liquid level, bottom level, interface level or density.

A vibrating screen for sifting out rock cuttings from drilling mud.

A shear valve is a ram-type BOP, similar in operation to a gate valve, but uses a pair of opposing steel plungers, rams. The rams extend toward the centre of the wellbore to restrict flow or retract open in order to permit flow.

A wheel which is grooved for use with vee-belts, ropes, round belts, wire or pipe.

A physical object that is a layer or surface with a shape in two dimensions and length in the third dimension surrounding a space. Typically the cylindrical part of a vessel.

A tubular heat exchanger in which a tube bundle is surrounded by a shell.

A hinged or sliding barrier used to control access to a high hazard area, made from robust materials used to protect personnel from exposure to hazards.

A damper intended for closing off parts of a ventilation system.

A completion component that is used to house gas-lift valves and similar devices that require communication with the annulus.

A physical object that is transparent and intended for viewing a vessel or piping system interior.

Visual signs to convey information or messages relating to item identification and locations. Conforming to standards as per type.

A detectable transmitted energy (e.g. voltage, current, pneumatic or magnetic field strength) by which information can be transmitted.

An electric cable intended for transmission of electric signals.

An electric signal transducer that is intended to convert one type of standardized transmission signal into another.

A physical object that is capable of receiving a signal and where the signal can be stored, recorded or converted into a useful form.
