The orlop is the lowest deck in a ship (except for very old ships). It is the deck or part of a deck where the cables are stowed, usually below the water line. It has been suggested the name originates from "overlooping" of the cables.
It has also been suggested that the name is a corruption of "overlap," referring to an overlapping, balcony-like half deck occupying a portion of the ship's lowest deck space. According to the Oxford English Dictionary, the word descends from Dutch overloop from the verb overlopen, "to run (over); extend").

The water flows from the highest chamber to the lowest chamber. As the gate opens in the lowest chamber, the water level lowers to sea level, and the ship enters. The gate closes behind it, and water flows from the chamber above to the level of the next gate, and the process is repeated until the ship reaches the top level.
