Zusammenfassung: | The invention discloses a motion correction method and system for the remaining maintenance time of an LNG tank container. The method comprises the steps that S1, the LNG tank container effective volume, the safety valve take-off pressure, the static evaporation rate, the heat insulation type, the LNG component and physical property parameters and the LNG tank container related information parameters are collected; s2, calculating the remaining holding time t of the LNG storage tank according to a saturation mean value model; s3, correcting the maintenance time t calculated by the saturation mean value model based on a heat flow non-uniform coefficient correction model to obtain the remaining maintenance time of the full tank in the storage yard standing state; and S4, judging whether the LNG tank is in a motion state or not, if yes, constructing a motion correction model of the remaining maintenance time, and correcting the remaining maintenance time according to the motion correction model on the basis of a |
