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 center 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.

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.

A device with one input and at least two outputs used for dividing a detectable transmitted energy (as a voltage, current, or magnetic field strength) by which information can be transmitted.

A physical object intended to reduce a noise level.

A vessel that has a bottom in the shape of a cone and is intended to store solid particles

A Single buoy mooring (SBM) or Single point mooring (SPM) is a loading buoy anchored offshore that serves as a mooring point and interconnect for tankers loading or offloading gas or fluid products. SBMs are the link between the geostatic subsea manifold connections and the weathervaning tanker. They are capable of handling any size ship, even very large crude carriers (VLCC) where no alternative facility is available.

A large basin with taps that supplies water.

an acoustic device producing a loud sound as a signal or warning.

Device which separates oil from water by mechanically wipe the oil of the water surface.

A conveyor consisting of a series of slats generally made of metal or wood attached to an endless chain.
