Abstract
In this research, an experimental method was used to evaluate the effects of a novel digital Decision Support System (DSS) for maritime ice management operations. This was done using a marine bridge simulator to determine whether the use of this technology can improve ice management performance. The experiment used the DSS to assist seafaring cadets in simulated emergency ice management operations. The operation scenarios saw the cadets use a supply vessel under their control to clear sea ice from the lifeboat launch zone of an offshore installation. The DSS allowed participants to request assistance, which was provided through text-based instructions and visual replay of a previous approach from a past study. The cadets usually adopted the strategy recommended by the DSS, but did not demonstrate statistically significant performance improvements, which we attribute to their lack of ship handling experience. This research provides insight into the efficacy of decision support technology in presenting advice for ice management activities. It also describes an effective method for evaluating this technology.
