Abstract

In China, most of the wave energy converter （WEC） is located at shallow water where the coral reef seabed cannot withstand excessive loads. To survival in frequent typhoon, design methods and dynamic analysis on the mooring system of “Nankun” WEC are studied. In the paper, three kinds of mooring lines is surveyed, which include the case of catenary, catenary + elastic cable, catenary + pontoon+elastic cable. Comparative studies show that： compared with the catenary case, elastic cable can reduce the mooring tension and increase the horizontal displacement of WEC, elastic cable+ pontoon can further reduce the mooring tension and reduce horizontal displacement of WEC. Theoretically, The catenary+pontoon+elastic cable is the best solution of mooring system of WECs n adapting to the harsh environment of shallow water.

Key words

wave energy converter （WEC） / mooring system in shallow water / elastic cable / coral reef geology / mooring tension
