The Institute for Ocean Technology (IOT, formerly the Institute for Marine Dynamics) of the National Research Council of Canada ( has conducted physical and numerical simulations of a TEMPSC (Totally Enclosed Motor Propelled Survival Craft) design in ice environments as an integral part of a broader research program that seeks to develop performance standards for Escape, Evacuation, and Rescue (EER) systems in harsh environments. The main objectives of this work are to define practical performance measures for the TEMPSC design in ice covered waters by experimentally investigating the hull’s ice transiting resistance and its motions, and to validate a numerical model of lifeboat sail away. This paper reports on the physical model experiments and their comparison with numerical modeling.
