Detailed discussions on the experimental results show that the dynamic responses and damage modes are much different, and the main hull sand-filled cylindrical shell is more...

... are evaluated in terms of stability requirements and dynamic response. A mathematical model is developed to estimate the first order heave and pitch motions of the platform. Experimental tests are carried out in order to calibrate this model. The response of each body alone is estimated numerically using...
