Abstract

This study employed viable methods for the selection of a preeminent mooring line amongst other alternatives for the mooring of a floating wave energy converter (WEC) in shallow water. Conventional mooring lines for mooring WEC are identified for optimal selection exercise. A combination of Entropy Weight and Visekriterijumska Optimizacijia I Kompromisno Resenje (VIKOR) methods is utilized in the aforementioned exercise. The two methods are effectively used in assessment of the attributes and performance of the various mooring lines in practical application. The result obtained, demonstrated that steel wire rope is the best mooring line suitable for a WEC system operations. It is good references to the marine and offshore engineering industries in decision making for optimal mooring line suitable for the mooring of a WEC system in shallow waters.
