SUBMERGENCE AND WAVE IMPACT LOADS DURING DRY TRANSPORTATION OF AN OFFSHORE STRUCTURE

摘要

In this paper, the submergence and wave impact loads acting on an offshore structure when transported on a heavy lift vessel has been experimentally studied. The nonlinear global system response under the effect of direct wave loads on the cargo has been investigated. An approach is developed to derive the global direct wave loads time history acting on the cargo in three-dimensions and correlate them to the submergence event. Numerical results are presented to illustrate this approach. Seafastening loads time history are also presented and correlated to the submergence event. Cargo Stability requirements against uplift and overturning on the vessel have been examined and reported.
