Implementation method for identification of dangerous scene of LNG storage tank leakage

Abstract

The invention discloses an implementation method for identification of a dangerous scene of LNG storage tank leakage. The method includes presetting accident occurrence possibility values and consequence seriousness values of LNG storage tank leakage, determining a risk matrix according to products of the accident occurrence possibility values and consequence seriousness values, and correspondingly obtaining risk levels corresponding to a plurality of products in the risk matrix; obtaining an accident occurrence possibility actual value and consequence seriousness actual value of LNG storage tank leakage, and obtaining a product of the accident occurrence possibility actual value and consequence seriousness actual value; and obtaining an actual risk level corresponding to the product of the accident occurrence possibility actual value and consequence seriousness actual value according to the risk matrix. In the implementation method for identification of the dangerous scene of LNG storage tank leakage, the risk level of each accident is accurately obtained through screening, and thus corresponding control measures can be accurately guided to be taken according to the risk level of the accident.

Description

technical field [0001] The invention relates to the technical field of gas pipelines, in particular to a method for realizing dangerous scene identification of LNG storage tank leakage. Background technique [0002] The dangerous accident scenario is based on the diversity of the accident development trend, through the systematic analysis of the internal and external related issues of the event, reveals a variety of possible event situations, and makes a description of the situation and situation from the beginning to the end of the event situation. That is to say, the accident scene refers to "the transmission path of the event from the cause to the result", which is a collection of a series of events. [0003] The existing hazard scene identification cannot accurately screen out the risk level of each accident, and it cannot accurately guide the corresponding control measures. [0004] Therefore, the prior art still needs to be improved and developed. Contents of the in...
