Abstract
In this paper, the dynamic performance of a work ship with a mooring line failure was studied. A fully coupled dynamic analysis program ANSYS/AQWA was applied to simulate ship motions and mooring line dynamics. The first- and second-order wave excitation forces were calculated using the three-dimensional diffraction/radiation theory, and the behaviors of the mooring lines were analyzed using a nonlinear finite element method. Under the combined environmental loads of waves and wind, one mooring line was intentionally disconnected at a certain moment. Then, the dynamic response after the mooring line breaks, the energy distribution characteristics in the motion response spectrum and the mean tension variation of the remaining mooring lines were discussed. The results showed that a sudden failure of the mooring line significantly affected the performance of the ship. To ensure the structural integrity of the ship system and the safety of personnel on deck, the influence of a mooring line failure on the ship should be investigated in advance.
期刊介绍：
Maritime Engineering publishes technical papers relevant to civil engineering in port, estuarine, coastal and offshore environments.
Relevant to consulting, client and contracting engineers as well as researchers and academics, the journal focuses on safe and sustainable engineering in the salt-water environment and comprises papers regarding management, planning, design, analysis, construction, operation, maintenance and applied research. The journal publishes papers and articles from industry and academia that conveys advanced research that those developing, designing or constructing schemes can begin to apply, as well as papers on good practices that others can learn from and utilise.
