n: (GVW) a free-running propeller mounted on or near the shaftdriven main propeller of a ship or tanker ship. The Grem vane wheel turns like a windmill because of the high-speed flow of water created by the main propeller. A GVW improves efficiency and thus can increase a ships speed without additional power.

n: (obsolete) kelly;kelly joint. grinding and buffing n: in pipeline construction, the process of cleaning pipe ends of dirt. rust, mill scale, or solvent to prepare them for welding. Grinding and buffing tasks are accomplished with power hand tools such as wire brushes and buffers. grind out v: to test for the presence of water in oil by use of a centrifuge.

n: refer to “kelly”

n: the number of kilojoules (Btu s) evolved by the complete combustion, at constant pressure, of 1 standard cubic metre of gas, with all of the water formed by the comoostion reaction being condensed to the liquid state.

n: (GOV) the total volume of all petroleum liquids and sediment and water, excluding free water. at observed temperature and pressure.

n: (GSV) the total volume of all petroleum liquids and sediment and water, excluding free water, corrected by the appropriate temperature correction factor (Ctl)for the observed temperature and API gravity, relative density, or density to a standard temperature such as 60�F or 15�C, and also corrected by the applicable pressure correction factor (Cpl) and meter factor.

n: (GSW) the total weight of all petroleum liquids and sediment and water (if any),excluding free water. It is determined by applying the appropriate weight conversion factors to the gross standard volume.

n: the interior capacity of a ship or a mobile offshore drilling unit. The capacity is expressed in tons, although the actual measurement is in volume, 1 ton being equivalent to 100 cubic feet of volume. This rule holds for measuring ship capacity for US maritime purposes. All principal maritime governments have their own rules describing how tonnage is to be measured.

n: the total amount of liquid in a storage tank excluding any adjustments for S&W, temperature, or density. Compare net volume.

n: full well stream volume, including all natural gas plant liquid and nonhydrocarbon gases, but excluding lease condensate. Also includes amounts delivered as royalty payments or consumed in field operations.

n: a wireline sheave, or pulley, that is fastened to the ground anchor and that changes a horizontal pull on a wireline to a vertical pull (as in swabbing with a derrick over a well). See block.

n: wire rope idle wheel attached to anchorage block is use to change the horizontal pull of wire rope as vertical pull 。
