n: the act of maintaining a floating offshore drilling rig on even keel, regardless of weather or load conditions.

n: I. the fore and aft reference line at the upper surface of the flat plate keel at the centre line for flush shell plate vessels. 2. the thickness of the garboard strake above that level for vessels having lap seam shell plating.

n: on a ship or floating offshore drilling rig, the balance when the plane of flotation is parallel to the keel.

n: the distance from the gauge, or reference, point from the bottom of a tank to a gauge, or reference, point at the top of the tank, usually on the hatch. On marine vessels, the measurement must be made when the vessel is on even keel.

n: the flat. horizontal section of the bottom shell plating measured from the centerline of the vessel to the edge of the flat keel plate.

n: a centreline strength tube running fore and aft along the bottom of a ship or a floating offshore drilling rig and forming the backbone of the structure.

n: a correction applied to cargo ullages when the vessel is not on an even keel. Valid only when liquid completely covers the tank bottom and is not in contact with the underside of the deck.
