n: 1. a vessel or tank that receives and temporarily stores a liquid used in a continuous process in a gas plant. See drip accumulator. 2. on a drilling rig, the storage device for nitrogen-pressurised hydraulic fluid, which is used in operating the blow out preventers. See blowout preventer control unit.

n: Used to store nitrogen that provide the hydraulic oil energy for BOP operation.

n: a bottle-shaped steel cylinder located in a blowout preventer control unit to store nitrogen and hydraulic fluid under pressure (usually at 3,(XK)pounds per square inch). The fluid is used to actuate the blowout preventer stack.

n: a system consisting of a beacon positioned on the seafloor to transmit an acoustic signal, a set of three or four hydrophones mounted on the hull of a floating offshore drilling vessel to receive the signal, and a position display unit to track the relative positions of the rig and the drill site. Monitoring of the display unit aids in accurate positioning of the rig over the site.

n: land owned by the United States, acquired by deed or otherwise. Such land has never been in the public domain or was in the public domain at one time and was later reacquired by purchase, condemnation, or donation.

n: a unit of volume often used in oil reservoir analysis, equivalent to the volume (as of oil or water) necessary to cover 1 acre to a depth of 1 foot

n: a part of a LACT unit installed ahead of the metering equipment to separate and remove mass volumes of air and gas from the fluid.

a surface piston driven pumping unit, similar to a beam lift unit.

n: a beam pumping unit on which the counterbalancing is done by means of an air cylinder.

n: an atmospheric fin tube exchanger that utilises air for cooling. Ambient air contacts the external fins by fanforced or natural draft. Also called air-fin unit or aerial cooler.

n: see air-cooled exchanger.
