For the governing sea state it has been

For the governing sea state it has been

**calculated**to be 13.33 m . The short term response in a range of sea - states has been**calculated**. The sea - states are represented by JONSWAP spectra and no wave energy spreading function is ...Page 69

The corresponding reliability index is

The corresponding reliability index is

**calculated**as 3.435 , 3.446 and 3.455 for n = 3 , n = 4 and n 6 respectively . It is seen that the component reliability index is only slightly affected by the number of tethers per tension leg .Page 275
