Glossary term Description
AMP

Alternative maritime power. To reduce ships generator exhaust emissions in port, ships may use plug-in shore power

American Rust Standards

Used to classify corrosion damage. The American Rust Standard is recognised worldwide

ALRS

Admiralty List of Radio Signals.

AIS

Automatic identification system, fitted to ships for transmitting ship's name and other data which can be received by other ships and shore stations

airdraught The distance between waterline and highest point on a vessel. Often used by dry bulk ports to describe the waterline to top of hatch cover clearance.
AHTS

Anchor handling tug supply

AGV

automated guided vehicle

adsorption delay Delayed take up of water vapour by the cargo. This usually refers to water vapour and describes the fact that during the day the water vapour is given off by the cargo to the air in the container (desorption) faster than the cooling of the container air is introduces water vapour to the cargo (adsorption). The water vapour condenses on the walls of the container thus leading to damage.

acceleration of shipment

Negative and positive accelerations are dynamic, mechanical stresses which occur in two main types during the transportation of goods:
- regular acceleration forces and
- irregular acceleration forces.

Regular acceleration forces primarily occur in maritime transport. Acceleration of up to one g (g = 9.81 [m/s²]) and, in extreme cases, even more, may occur due to rolling and pitching in rough seas. Such regular acceleration forces have an impact on the effort involved in load securing.

Irregular acceleration forces occur during cornering or when a train passes over switches, during braking, starting up, hoisting and lowering. Such acceleration forces are not generally repeated, but they may occur several times at varying intensities during transport. These are the typical stresses of land transport and transport, handling and storage operations.
