Research and Countermeasures on LNG Ship Port Area Navigation Risk Assessment Based on Fuzzy Comprehensive Evaluation Method

Abstract

As a new energy source, LNG occupies an important position in the energy structure, and it is of great significance to carry out research on the navigation risks of LNG ships as carriers. Through the establishment of an LNG ship port area risk evaluation index system, the an exponential scale method in the analytic hierarchy process is used to calculate the weight value of each index, and the fuzzy comprehensive evaluation method is used to calculate the navigation risk level of LNG ships. An LNG ship in Lusi port area of Nantong Port is selected for risk assessment, and based on the results of the risk evaluation, a targeted risk control plan is proposed.
