Crushing for recycling is the sensible procedure for two reasons: incinerated or crushed glass cannot be discharged overboard; land-based facilities will not accept ash-contaminated glass for recycling.
A combination of thin fibres of glass in various forms which, when mixed with resin cures to produce a hard, strong and chemically inert material.
Global dimming is the reduction in the amount of global direct irradiance at the Earth's surface that has been observed since systematic measurements began in the 1950s.
The worlds total energy consupmtion by all available resources.
A satellite-based navigation system operated and maintained by the US Department of Defense. GPS consists of a constellation of 24 satellites providing worldwide, 24-hour, three dimensional (3D) coverage.
Global strategic petroleum reserves (GSPR) refer to crude oil inventories (or stockpiles) held by the government of a particular country, as well as private industry, to safeguard the economy and help maintain national security during an energy crisis.
The effect of temeparture increase over time across the globe.
Measurement of life-cycle greenhouse gas emissions involves calculating the global-warming potential of energy sources through life-cycle assessment. The findings are presented in units of global warming potential per unit of electrical energy generated by that source.
The ratio of the warming caused by a certain substance to the warming caused by a similar mass of carbon dioxide (the GWP of CO2 is defined to be 1,0). All GWP values are calculated over a 100-year time horizon.
A freely available resource detailing known wind properties around the globe.
Established in 2005 to provide a credible and representative forum for the entire wind energy sector at an international level.
A valve with a spherically-shaped body enclosing the valve seat or disc. Liquid flow is arranged from the below to the above of the valve seat so that the upper chamber is not pressurized when the valve is closed.
An integrated communication system which uses satellite and terrestrial radio communication to ensure that no matter the ship’s position in distress, assistance can be sent.
The removal of metal from a welded seam in order to make a back-run for a butt weld. Gouging is frequently employed in preference to grinding for the removal of large quantities of weld metal prior to repairs or modifications to the weld preparation.
A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine.
During normal operation, the engine speed is controlled by a governor which regulates the injected fuel quantity corresponding to the load. The governor shall prevent the engine from exceeding the rated speed by more than 15%.
A bulk cargo-handling device consisting of a bucket which is hinged to open and close. It is open when lowered into the cargo and then closed and lifted out full.
Certain types of bulk cargoes may be discharged by means of special grabs. Such grabs are either connected to ship derricks or to shore cranes.
Wheat, maize (corn), oats, rye, barley, rice, pulses, seeds and their processed forms. Grain stows at 1.2 – 2.0m3/t. It has a low angle of repose and shifts easily if not properly stowed.
The cubic capacity of a cargo hold measured to the shell plating.
