液化天然气罐式集装箱水路运输试验及分析

为了评估液化天然气罐式集装箱水路运输安全性,我国开展了首次液化天然气罐式集装箱水路运输试验。试验观测了液化天然气罐式集装箱的压力、液位等变化情况。通过对此次试验观测到的现象及试验数据进行综合分析后,认为:液化天然气罐式集装箱在水路运输过程中,罐内压力缓慢增长、处于安全范围以内(罐内压力小于0.74 MPa),罐体未出现损坏、腐蚀、变形等现象。同时为了有效控制运输风险,提出了保障液化天然气罐式集装箱水路运输安全的相应建议。

Test and Analysis of LNG Tank Container Waterway Transportation

To assess waterway transportation safety of LNG tank container,the first waterway transportation test for LNG tank container in China was conducted.In the test the pressure and liquid-level in LNG tank container were measured.It is indicated by the analysis of test data that in the process of LNG tank container waterway transportation,the pressure in LNG tank container was increasing slowly within a safety range(tank pressure<0.74 MPa),and the phenomenon such as damage,corrosion,and deformation of LNG tank container didn't occur. Some relevant suggestions to assure waterway transportation safety of LNG tank container for controlling transportation risk effectively are put forward.
