[0002] The hull tightness test is a test to check whether there is leakage or seepage in the hull joints. According to regulations, different parts of the hull are tested by flushing, pouring, water pressure, oil pressure, water spraying, airtightness, kerosene, oil mist and other test methods.

[0003] When inspecting the bottom of the ship, vacuum negative pressure is used for inspection. Foam is applied in a circle around the inspection site, and then the inspection site is covered with an inspection cover.
