Abstract
Based on the multimodal transport mode of LNG container, it is suitable for transportation, storage and land, and it can realize safe, high efficiency and convenient transportation, and meet the needs of modern LNG transportation. This paper discusses the change trend of LNG terminal berth length which has been built in recent years. The research progress of berth length optimization method of LNG terminal in China is described. The comparison analysis is made with the berth length optimization method of open oil and gas terminal, and some suggestions are put forward.
Highlights
By the end of 2020, 22 LNG receiving and unloading berths have been built and put into operation in China, and 22 LNG receiving stations have been built and put into operation in China, with a receiving capacity of 90.35 million tons / year
The supporting storage tanks of each large LNG terminal berth are mainly 2-4 160000 m3 tanks, which are generally small in scale
The change trend of the ratio of berth length to ship length of LNG terminal is shown in Figure 1, in which the berth length is calculated to the outer edge of the outermost mooring structure
Summary
By the end of 2020, 22 LNG receiving and unloading berths have been built and put into operation in China, and 22 LNG receiving stations have been built and put into operation in China, with a receiving capacity of 90.35 million tons / year. The supporting storage tanks of each large LNG terminal berth are mainly 2-4 160000 m3 tanks, which are generally small in scale. The capacity of storage and transportation system is insufficient, and the capacity of peak shaving and cross regional regulation is limited. The construction of several LNG terminals has been gradually optimized
