The Impacts of Mooring Line Failure for Box-Shape Aquaculture Net Cages

摘要

The purpose of this study is not only to investigate the impacts ofmooring line failure for box-shape aquaculture net cages but also topropose an improved solution to prevent this event occurred. In thisstudy, three different scenarios including central mooring line failure,lateral mooring failure, both central and lateral mooring line failure areadopted. The most serious condition is found in the case of both centraland lateral mooring line failure. The ratio of maximum mooring tensionbetween the most serious condition and the normal condition is about1.48. This value can use to determine the safety factor of mooring system.The improved solution is deploying three additional mooring anchors onthe upstream side, the results show that this solution can significantlyreduce the maximum mooring tension on each upstream anchorscompared to the normal condition.
