APPARATUS AND METHOD FOR MEASURING THE SLOSHING IN THE CARGO TANK OF A LIQUEFIED NATURAL GAS CARRIER
Document Type and Number:
WIPO Patent Application WO/2013/062147
Kind Code:
A1
Abstract:
The present invention relates to an apparatus for measuring the sloshing in the cargo tank of a liquefied natural gas carrier, and to a method using same for measuring the sloshing in the cargo tank of a liquefied natural gas carrier, wherein the apparatus comprises: a plate-shaped floating mat coupler which floats on the surface of the liquefied natural gas contained in the cargo tank of a liquefied natural gas carrier and moves in accordance with the movement of the liquefied natural gas; and an optical sensor measuring acceleration using optical sensor technology to measure acceleration when the floating mat coupler floats by being inserted in one or more positions in the floating mat coupler. According to the present invention, the characteristics of the movement occurring in accordance with the sloshing of the liquefied natural gas in the cargo tank of a liquefied natural gas carrier, and the shock and deformation which the inner wall of the cargo tank is subjected to because of such movement, are measured at multiple angles, and said factors are effectively analyzed in order to accurately determine the problems that the sloshing of the liquefied natural gas causes for the cargo tank, and to enable more thorough design and maintenance and repair of a cargo tank on the basis of the determined problems.
