The invention relates to an application method for cutting a hole in an airtight chamber of an upturned ship. The method comprises the following steps of 1) sealing the bottom surface of a sealed chamber body through a sealing component and fixing the sealing chamber body at the bottom of the upturned ship; 2) exerting a cutting personnel to open an outer sealing door, enter a transitional chamber, close the outer sealing door, open an inner sealing door, enter a working chamber and close an inner sealing door; charging gas into the working chamber through an airtight mouth to supercharge the working chamber; performing leakage detection and leakage prevention on the working chamber after the working chamber is supercharged; and then cutting a hole in the bottom of the upturned ship through cutting equipment; and 3) after the hole is cut, exerting the cutting personnel to enter the transitional chamber, close the inner sealing door and walk out of the sealed chamber body; exerting divers carrying oxygen cylinders to enter the transitional chamber, close the outer sealing door, enter the working chamber, close the inner sealing door and enter the interior of the upturned ship from the hole so as to carry out rescue work. As rescuers carry out hole-cutting and rescue works under a sealed environment provided by the airtight chamber, the operation is safe, the efficiency is high and rescue time is saved.
