A FUNDAMENTAL STUDY ON ANCHOR PERFORMANCE EVALUATION FOR MARINE ACCIDENT PREVENTION

摘要

From the viewpoint of prevention of the accident of ships under anchorage, an anchor is a very important device. The anchor with various types and performances has been developed over the centuries. For example, JIS types and AC-14 types are mostly applied to Japanese ships at present. However, marine accidents by dredging anchor are not eliminated even now. There still seems a room for improvement of its performance by changing shapes and forms. There may be a problem also in the experiment method and a valuation method. The purpose of this research is to perform an anchor performance re-evaluation for marine accident prevention. The candidates for an experiment are JIS type, AC-14 type, DA-1 type stockless anchor and Danforth type stock anchors.
