101443 - Development of Ice-Load Algorithm for Real-Time Feedback During Simulator Training 

The use of simulator training for ice navigation is becoming increasingly widespread, in part due to the difficulty, risk, and expense of providing training on vessels in ice-covered waters. Simulator training offers the opportunity for comparatively inexpensive and low risk training for novices in ice-covered conditions. For effective ship operation, it is important to use a vessel to its capacity in ice, without exceeding this capacity and causing damage to the structure. To this end, an algorithm was developed that detects ship-ice collisions, calculates the ice-loads on the structure, and provides the operator with feedback in terms of how close the load is to exceeding the safe capacity of the structure. At present, the algorithm is ship specific in that its development uses finite element analysis for a specific ship to assess the ship’s structural response for a given ice thickness, strength, and contact geometry, to determine the maximum energy at which a safe collision can occur. This safe collision energy limit can then be implemented into simulator training to give real-time feedback to participants about the safety of ship-ice collisions as they occur. An experimental campaign to test the effect of the feedback for simulator training, as well as its utility as an aid onboard the bridge of ships, is proposed.
