Inert gas

energy

An inert gas is a gas that does not undergo chemical reactions under a set of given conditions.

Inert gas blower

marine

Blowers are used to deliver the scrubbed flue gas to the cargo tanks. At least two blowers shall be provided.

Inert gas generator (IGG)

marine

A device, similar to a boiler, in which fuel is burnt to create exhaust gases which contain less than 5% oxygen. Inert gas generator consists of a combined burner and scrubber, both seawater-cooled.

Inert gas production plants

marine

1. Flue gas system - If available, flue gas from ship boilers can be used for inerting. The flue gas system washes and cools the boiler flue gas, and delivers it to the cargo tanks during cargo unloading and tank washing.

Inert gas system

marine

A system of preventing any explosion in the cargo tanks of a tanker by replacing the cargo, as it is pumped out, by an inert gas, sometimes by flue gas from ship boilers.

Inertia

energy

Inertia is the resistance of any physical object to any change in its velocity.

Inertial confinement fusion

energy

Inertial confinement fusion is a type of fusion energy research that attempts to initiate nuclear fusion reactions by heating and compressing a fuel target, typically in the form of a pellet that most often contains a mixture of deuterium and tritium.

Inerting

marine

Creation of an inert atmosphere in tanks or in the surrounding void spaces to prevent explosive conditions, reduce corrosion or detect leakage.

Inflammable liquids

marine

Liquids liable to spontaneous combustion giving off inflammable vapours at or below 80 degrees F. For example: ether, ethyl, benzine, gasoline, paints, enamels, carbon disulfide, etc.

Inflatable appliance

marine

An appliance which depends upon non-rigid, gas-filled chambers for buoyancy and which is normally kept uninflated until ready for use.

Inflated appliance

marine

An appliance which depends upon non-rigid, gas-filled chambers for buoyancy and which is kept inflated and ready for use at all times.

Information

energy

Information can be thought of as the resolution of uncertainty; it answers the question of "What an entity is" and thus defines both its essence and the nature of its characteristics.

Infrared thermometer

energy

An infrared thermometer is a thermometer which infers temperature from a portion of the thermal radiation sometimes called black-body radiation emitted by the object being measured.

Inherent safety

energy

In the chemical and process industries, a process has inherent safety if it has a low level of danger even if things go wrong.

Inhibitor

energy

A fluid additive specifically designed to decrease the rate of oxidation in metal (rust) and promotion of microbial life (bacteria) in the closed-loop circulating fluid.

Inhibitors

marine

Substances used to prevent or retard a chemical or electro-chemical reaction, often used to render corrosion products less soluble and thereby tending to restrain electro-chemical processes.

Injection

marine

The process of spraying fuel into an engine cylinder by an injector.

Injection well

energy

An injection well is a device that places fluid deep underground into porous rock formations, such as sandstone or limestone, or into or below the shallow soil layer.

Injector, fuel valve

marine

A device which receives pressurized fuel as a liquid and sprays it into an engine cylinder as a fine mist. It consists of a nozzle and nozzle holder or a body.

INMARSAT

marine

The Organization established by the Convention on the International Maritime Satellite Organization adopted on 3 September 1976.
