Experimental study of a hybrid mooring system
- 835 Downloads
Mooring systems are essential to the floating structures including offshore platforms, wave energy converters and floating breakwaters. As floating structures propagate towards deeper waters, the design of the mooring systems needs to be revamped. In the present study, a new hybrid mooring system has been proposed. A series of weights and buoys are arranged to the different segments of each mooring line in order to improve the motion performance of the platform and eliminate the vertical forces at the lower end of the mooring lines. A series of experiments have been carried out at CSSRC wave basin for a semi-submersible platform moored by the mooring lines with or without the weights and buoys. The mooring lines’ tension and 6-DOF motions of the platform were measured. Discussions have been made on non-linear motion responses of the semi-submersible and non-linear mooring line tension responses for various mooring conditions.
