... production. The less amounts of motion the more safe operation is. The experiment was conducted under condition as follows: time peak period (T p ) 1.85 – 2.15 second and significant (H s ) wave height 7.29 – 10 cm. Surge, heave and pitch response amplitude operation (RAO) of moored semisubmersible...

... the added mass and damping. The spar with single disc configuration is studied varying the disc diameter. The spar with twin disc configuration is studied varying the spacing of disc. The disc diameter and spacing is obtained for the permissible heave response of 5m and pitch of 4 degrees considering...
