測深管。 Sounding tubes for draft measurement with small holes are installed vertically downward from the upper deck to below the light waterline of the hull on both sides of the inside of the ship at the bow and stern and amidships. A small air vent hole is provided directly below the upper deck that communicates at right angles with each lower end of the sounding pipe for draft measurement, and is piped through the hull skin, and surrounds the sounding pipe for draft measurement with a small hole. A double-pipe structure is created by piping envelope pipes provided vertically downward from the upper deck, and a sounding scale is inserted from the upper deck into the sounding pipe with a small hole for measuring the draft. A sounding pipe for measuring draft, characterized in that the draft is measured by measuring the distance from the head of the sounding pipe to the water surface.
