Collision risk assessment of LNG filling barges

With the rapid development of inland LNG fuel-powered ships, the safety of LNG filling barges has aroused widespread concern. In order to assess the collision risk of LNG filling barge, using Kunz model to calculate collision probability under different conditions. Analyze the risk of the collision according to the collision probability of LNG filling barges, and calculate the warning range of LNG filling barges according to the acceptability of risk. Based on the ship data collected by AIS and video, the fuzzy comprehensive evaluation method is used to analyze the influence of transverse distance, yaw angle, relative azimuth and collision angle, and assess the collision risk of LNG filling barge.
