CARGO SPACE APPARATUS FOR ANALYZING A DEFECT OF A SHIP AND A METHOD, CAPABLE OF EXACTLY SIZING A DEFECT OF A BARRIER IN A TANK INNER SURFACE OF A CARGO SPACE OF A LIQUEFIED NATURAL GAS CARRIER

摘要

PURPOSE: A cargo space apparatus for analyzing a defect of a ship and a method are provided to exactly size a defect of a barrier in a tank inner surface of a cargo space by measuring temperature and pressure by a thermal pad.;CONSTITUTION: A cargo space defect analysis apparatus of a ship comprises a thermal pad(204) which heats the membrane unit of the first wall inner side of the cargo space of the ship by generating the heat of the constant temperature, a reference pad which is applied to the each membrane unit of the non-defective region of the first wall inner side and offers a reference temperature, a temperature measuring part(408), a pressure measurement part(404) which measures the pressure at the isolating space of the cargo space, and a controller(400) which stops the heating of the thermal according to the pressure measured through the pressure measurement part. The controller detects the temperature and time change difference of the standard pad by referring the temperature value from the temperature measuring part after the heating stopping of the thermal pad.;COPYRIGHT KIPO 2010
