LNG terminals work with low storage to throughput ratios compared with an oil terminal. The reason for the low storage levels is the cost of building LNG tanks, which are the most expensive part of a conventional terminal and take upwards of three years to construct. Because of the expense of the tanks, most terminals designed for throughput up to 5 mtpa will be constructed with only two tanks – each of which will have roughly the same capacity of an LNG ship (approx. 130,000 – 160,000 cubic meters). Although it is possible to operate a terminal with only one tank, the logistics of this require very reliable delivery and offtake
