Effect of taut and catenary mooring on spar platform with 5MW wind turbine

The behavior of spar platform with 5MW wind turbine due to the interaction of regular and random waves is studied experimentally. A 1:100 scale model of the spar is studied in the wave basin. The studies are carried out for the wave height of about 6m and wave periods in the range of 6s to 28s. The effect of square plate of size 24×24m at the bottom of the spar on the vertical and horizontal acceleration at the top of the wind tower in regular and random waves is reported. The effect of taut and catenary mooring on spar platform is also studied. The horizontal and vertical response amplitude operators (RAO) for the regular and random wave tests are compared.
