MODEL TESTING OF OFFSHORE STRUCTURES AT THE INSTITUTE FOR MARINE DYNAMICS

The Institute for Marine Dynamics, St. John's, Newfoundland, is developing facilities and techniques to determine the responses of offshore structures to the environments of waves, wind, current and ice. Unidirectional random and regular waves can be generated in the clearwater towing tank, the shallow water towing tank, and the offshore basin. In addition, the offshore basin can generate multidirectional waves. Wind is simulated using a bank of high capacity fans whose speed is fluctuated to create turbulence spectra. Currents are generated using arrays of nozzles charged by circulation pumps. In addition to test programs utilizing these facilities, model test experiments have been carried out in the ice tank facility on both fixed and floating model structures to measure ice forces against the structures as well as to observe the movement of ice in the vicinity of these structures.
