DOI

Declaration of Inspection - a specific checklist of certain tasks which are required to be completed prior to a oil, gas, or liquid hazardous material transfer over water in the United States. It is to be completed by the persons in charge from the terminal facility, barge, truck, or vessel and the vessel discharging or receiving the product(s). Both parties must sign all points on this checklist. The form must be made available for inspection teams from the USCG when requested, not just for current transfers, but for previous transfers as well.

(DOI) - a specific checklist of certain tasks which are required to be completed prior to a oil, gas, or liquid hazardous material transfer over water in the United States.

MEMBRANE WATERPROOFING

Curing concrete, especially in pavements, by spraying a liquid material over the surface to form a solid, impervious layer which holds the mixing water in the concrete. Also known as membrane curing.

LIQUID SEMICONDUCTOR

An amorphous material in solid or liquid state that possesses the properties of varying resistance induced by charge carrier injection.

BEATER

  1. A tool for packing in material to fill a blast hole containing a charge of powder. 2. A laborer who shovels or dumps asbestos fibers and sprays them with water in order to prepare them for the beating. 3. A machine that cuts or beats paper stock.

HOLDUP

  1. Volume of material held or contained in a process vessel or line. 2. Liquid held up (suspended) in a vertical process vessel or line by rising gas or vapor streams.

VIRGA

Wisps or streaks of water or ice particles falling out of a cloud but evaporating before reaching the earth’s surface as precipitation. Virga is frequently seen trailing from altocumulus and altostratus clouds, but also is discernible below the bases of high-level cumuliform clouds from which precipitation is falling into a dry subcloud layer. It typically exhibits a hooked form in which the streaks descend nearly vertically just under the precipitation source but appear to be almost horizontal at their lower extremities. Such curvature of virga can be produced simply by effects of strong vertical windshear, but ordinarily it results from the fact that droplet or crystal evaporation decreases the particle terminal fall velocity near the ends of the streaks. Also called FALL STREAKS, PRECIPITATION TRAILS.

LAYDAYS

The number of days contractually agreed upon when vessel loading or discharging is to take place without additional charge or demurrage being paid. See Laytime.

GRAVING DOCK

A narrow basin, usually made of earthen berms and concrete, closed by gates or by a caisson, into which a vessel may be floated and the water pumped out, leaving the vessel supported on blocks; the classic form of drydock.

DOCKAGE

A charge by a port authority for the length of water frontage used by a vessel tied up at a wharf.

ULF STREAM

A warm, well defined, swift, relatively narrow ocean current which originates where the Florida Current and the Antilles Current meet north of Grand Bahama Island. It gains its impetus from the large volume of water that flows through the Straits of Florida. Near the edge of the Grand Banks of Newfoundland extensions of the Gulf Stream and the Labrador Current continue as the NORTH ATLANTIC CURRENT, which fans outward and widens in a northeastward to eastward flow across the ocean. The Florida Current, the Gulf Stream, and the North Atlantic Current together form the GULF STREAM SYSTEM. Sometimes the entire system is referred to as the Gulf Stream The Gulf Stream forms the western and northwestern part of the general clockwise oceanic circulation of the North Atlantic Ocean.
