Effect of Snubber Hose in Mitigating Environmental Responses of Electrical-mechanical Cable Subsurface Mooring

Abstract:

A mathematical model of environmental responses for electrical-mechanical cable subsurface mooring （EMC-SSM） was established to solve the problem of the significant dynamic response of EMC-SSM under extreme sea conditions. The effectiveness of the snubber hose in matigating the environmental response of EMC-SSM and the effect of different configurations of the snubber hose on the mitigation were studied by calculating the tensile response of a specific type of EMC-SSM under sea conditions with a 100-year reoccurrence period. The results show that the dynamic response of EMC-SSM is inhibited with an appropriate length of snubber hose. However，the dynamic response of EMC-SSM is enhanced when the length of snubber hose is inappropriate. Finaly， the configuration principle of the snubber hose and the method for determining the shortest effective length were also presented.
