A physical object that can be any electrical device, usually incorporating an electromagnet, whereby a current or signal in one circuit can open or close another circuit.

A self operating valve that is set to open at a certain pressure level to prevent the pressure in a container or system from reaching unsafe levels.

A RTU, or Remote Terminal Unit is a device which interfaces objects in the physical world to a DCS or SCADA system by transmitting telemetry data to the system and/or altering the state of connected objects based on control messages received from the system.

Assigned for living and accommodation.

A temperature sensing element that operate on the principle of changes in electrical resistance of pure metals (sintered semiconductor material) and are characterized by an almost linear positive change in resistance with temperature.

An orifice plate that is intended for use as a restrictor.

Vertical structure used to resist the lateral pressure of the ground and maintains structural integrity.

Is a water treatment facility that uses a membrane filtration process to remove ions, molecules, particles and salts from source water by applying pressure to force water across a semipermeable membrane, producing purified water and a concentrate reject stream.

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 totally sealed, gas-insulated compact switchgear unit. The primary switching devices can be either switch disconnectors or fused switch disconnectors or circuit breakers.

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

A support connecting a riser to a structure.

Is a civil item intended for vehicle traffic.

A machine used to compact soil, gravel, concrete, or asphalt in the construction of roads and foundations

A mechanical cable that is a large stout cord of strands of fibres twisted or braided together.

A variable area flow meter which consists of a tapered tube of glass with a float inside that is pushed up by flow and pulled down by gravity.

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.
