Title:
STATE ESTIMATION SYSTEM FOR LIQUEFIED GAS TANK FOR VESSEL AND STATE ESTIMATION METHOD
Document Type and Number:
Japanese Patent JP2022104038
Kind Code:
A
Abstract:
To predict state of a liquefied gas tank for vessel at high accuracy.SOLUTION: A system (1) for estimating state of a liquefied gas tank (7) installed on a vessel (3) includes: a measuring unit (31) including a measuring instrument (39) for measuring state regarding strength of the liquefied gas tank (7); a calculation unit (33) for calculating the state regarding the strength of the liquefied gas tank (7) by a preliminary analysis model; a data assimilation unit (35) for updating a prior analysis model by data assimilation using the measurement result acquired by the measuring unit (31); and an evaluation unit (37) for evaluating state of the liquefied gas tank (7) based on the calculation result outputted from the calculation unit (33).SELECTED DRAWING: Figure 1
