that when the offset ratio is 1 or more the influence of the external har can be substantially eliminated in the case where the offset ratio is 1 or more similar to the layout illustrated in fig1 the lng trains may be arranged along the same straight line in the longitudinal direction of the lng trains and the distance between the trains distance y in fig9 may be set to zero when the lng trains are shifted from each other in the longitudinal direction the total area required to place the lng production facilities increases and the lengths of pipes that connect the lng trains and utility facilities also increase therefore there is a possibility that the cost will be increased compared to the conventional case where the plot area is minimized in the example illustrated in fig1 since the distance between the trains distance yin fig9 is reduced to zero the dead zone can be reduced as a result the increase in cost can be reduced fig1 illustrates lng production facilities in which a utility facility is arranged for each train as shown in the lower part of fig1 the utility facilities for the respective trains utility for train 1 2 3 other than a common utility facility common utility shared by all of the trains are separately arranged for the respective trains that are shifted from each other in the longitudinal direction.
