An iceberg drifting or being transported across the ocean experiences both oscillations or rigid-body responses and vibrations or elastic-body responses as the result of wave-induced dynamic loading. The magnitude of the resulting wave bending moment, shear force and roll are calculated and the strength and stability of iceberg under rough sea conditins are checked. The analysis is based upon the theory of Korvin-Kroukovsky. Different iceberg length, width and depths are considered under extreme sea conditions. In the design of mooring cable systems the plastic properties of ice and re-gelation need to be considered, metal piles and bollards are shown to move in the direction of applied force and as a result the mooring cable systems will not perform its function. Thus, either fiber ropes surrounding the iceberg can be used or the pile systems and the bollards must be manufactured from a material having poor thermal conductance.
