Objectives/Methods: The main objective here is to make an optimum design of buoy. Wave power generation is one of the extensive research fields all over the world. The ocean waves are usually converted into electrical energy by a device called a wave energy converter (WEC). The electricity generated depends upon the intensity of the waves. In a traditional way, the motion of a buoy that occurred in a vertical direction due to waves in water, can be converted into current generation. Here, the numerical simulation using the Ansys tool is done to find an optimum design of buoy shape to get maximum energy conversion. Findings: The simulations have shown that the drag force for the Oval shape is minimum 0.063 N and the first mode of frequency for the Conical shape is minimum 165 Hz for Point-Absorber type Wave Energy Converter.

“…Numerous studies have been conducted to evaluate the effectiveness of the various mooring lines for different offshore installations as evidenced in the papers by [6][7][8]. In [9], a review of design issues and choices of mooring systems for WECs are explained. The authors discussed a variety amongst the commonly used mooring systems and their compatibility for WECs.…”

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.

This paper presents the design and analysis of a mooring buoy and its mooring systems to moor a floating platform mounting an arrayed Wave Energy Converters (WECs). The mooring buoy allows the WEC platform to weathervane around the mooring buoy freely by the prevailing environment directions, which enables consistent power generation. The WEC platform is connected to the buoy with synthetic hawsers, while station-keeping of the buoy is maintained with catenary mooring lines of chains tied to the buoy keel. The buoy also accommodates a power cable to transfer the electricity from the WEC platform to the shore. The WEC platform is designed to produce a total of 1.0 MW with multiple WECs installed in an array. Fully coupled time-domain analyses are conducted under the site sea states, including extreme 50 y and survival 100 y conditions. The buoy motions, mooring tensions and other design parameters are evaluated. Strength and fatigue designs of the mooring systems are validated with requirements according to industry standards. Global and local structural designs of the mooring buoy are carried out and confirm the design compliances.
