The Open Access Same-Time Information System (OASIS), is an Internet-based system for obtaining services related to electric power transmission in North America.

A non-pressurized compartment at ambient pressure that allows the diver to be transported to and from the work site.

Open energy system database projects employ open data methods to collect, clean, and republish energy-related datasets for open use.

The nuclear fuel cycle is referred to as an open fuel cycle if spent fuel is not reprocessed.

An ocean or sea outside territorial limits, i.e. international waters.

An open system, which both matter and energy can enter or exit, though it may have variously impermeable walls in parts of its boundaries.

The ratio of the thrust power to the power absorbed by the propeller operating without a hull attached, i.e. in open water.

The open-circuit test, or no-load test, is one of the methods used in electrical engineering to determine the no-load impedance in the excitation branch of a transformer.

Open-circuit voltage is the difference of electrical potential between two terminals of a device when disconnected from any circuit. There is no external load connected.

A simple configuration of gas turbine including a compressor, combustion chambers and turbine.

The external openings may be listed into the following categories, depending on their means of closure: unprotected, weathertight, watertight. Only watertight openings do not lead to progressive flooding.

In an open-loop control system, the control action from the controller is independent of the process variable.

Built by IHC Holland Dredgers BV Shipyard the RIJNBORG is the open top cellular container carrier with a capacity of 1700TEU. This type of vessel is characterized by the absence of hatch covers, allowing fast loading and unloading.

In the middle of 1990’s, Dole Fresh Fruit International looked for vessels able to transport 1000 reefer 40ft containers.

The operating reserve is the generating capacity available to the system operator within a short interval of time to meet demand in case a generator goes down or there is another disruption to the supply.

The temperature at which an electrical or mechanical device normally operates

The range of temperature from minimum operating temperature to maximum operating temeperature that a device will operate as designed.

Engine data, like cylinder peak pressure, exhaust gas temperature, etc., from the engine log which are related to the NOx emissions performance.

An instruction book provided by manufacturer, which details the correct operating procedure for a piece of equipment.

Ready for immediate use.
