Abstract

At 2:37: 34 seconds on April 14, 2017, a large area of Qinglan Zone suffered a power outage. During the troubleshooting of the power supply bureau, it was found that there was a suspicious self-unloading vessel "HXX 338" anchored in the anchor forbidden area of submarine cable and weighed anchor. Hainan Power Grid sued the suspicious ship and won the lawsuit, but the shipowner insisted on the ship not damage the submarine cable. Power grid entrusts the author as maritime expert, make a professional judgment with respect to the suspicious of this accident. The author makes use of navigation common sense: after anchoring, the position of the ship must be within the radius of the arc with the anchor position as the center of the circle, the length of the chain thrown out plus the sum of the distance between bridge and anchor chain hole; put in another way, if the ship's position is known after anchoring, the anchor position must be in a circle with the ship's position as the center of the circle, the length of the chain thrown out plus the distance between bridge and the bow's chain hole and as the radius. The trajectory of the ship was analyzed, and the suspicious ship was identified as the ship resulting in the accident. Investigate and analyze the facts of the ship in question moved in the prohibited anchor zone and hooked up submarine cables, find out the causes and distinguish the responsibilities. This article has explored an effective analysis for maritime investigation.
