Computational mechanics of the full-scale and model-scale roll-on, roll-off (RORO) stern ramp and experimental modal analysis of the model-scale ramp and support.

It has been determined that current stern ramp designs lack adequate structural integrity during Sea State Three roll-on, roll-off (RORO) operations. Therefore, passive isolation between the stern ramp and the roll-on, roll-off discharge facility (RRDF) is being investigated as a means of reducing r...
