Study on relative safe distance between anchorage outside harbor and surrounding Marine resources

At present, there is no unified standard for the relative safe distance between the anchorage outside the harbor and other offshore structures, shoals, reefs, etc., and there is no specific reference conclusion in the existing research results, which causes confusion for the planning, site selection and protection of offshore anchorage. In this paper, the research about the location of the anchorage requirements in China based on the relative safety of anchorage and the surrounding sea resources distance conducted in-depth research, mainly studies the mooring ship go, drifting direction and speed of dragging anchor process three aspects, such as through the ship maneuvering simulation test further study of the mooring ship may be dragging speed, finally put forward to determine the anchorage and surrounding facilities (or observation) relatively safe distance calculation method. On the basis of the above research, this paper gives some suggestions on the safe avoidance distance of the anchorage outside the harbor, and solves the problem of the specific standards for the safe avoidance of the anchorage outside the harbor, which can be used as a reference for the site selection of the anchorage outside the harbor and the protection of the anchorage resources.
