Length on the Water Line; the designed waterline for the vessel at her loaded displacement, more accurately termed the load water line or summer load line. The later is marked with the loadline marks (plimsoll line) to ensure compliant loading for the intended sea area of the passage.

CORROSION INHIBITOR
Additive for protecting lubricated metal surfaces against chemical attack by water or other contaminants. There are several types of corrosion inhibitors. Polar compounds wet the metal surface preferentially, protecting it with a film of oil. Other compounds may absorb water by incorporating it in a water-in-oil emulsion so that only the oil touches the metal surface. Another type of corrosion inhibitor combines chemically with the metal to present a non- reactive surface.
