Means of sounding

(1) In all ships other than barges with no under deck cargoes, means for sounding, to the satisfaction of the Administration, shall be provided– (a) for the bilges of those compartments which are not readily accessible at all times during the voyage; and (b) for all tanks and cofferdams. (2) Where sounding pipes are fitted, their upper ends shall be extended to a readily accessible position and, where practicable, above the freeboard deck. Their openings shall be provided with permanently attached means of closing. Sounding pipes which are not extended above the freeboard deck shall be fitted with automatic self-closing devices.
