Bering Sea Topside Icing Probabilities for Two Naval Combatants
Abstract
Ice accretion aboard vessels operating in cold weather regions has received much attention in recent years. Research efforts associated with vessel icing in the past have achieved a good understanding of the thermodynamic processes associated with ice accretion and brine drainage. Unfortunately, the bow spray production processes, which affect water delivery to a particular vessel in an icing situation are not at all well understood. As a result, most mathematical models which predict topside icing are empirical in nature and are mainly applicable to fishing vessels because they were derived from fishing vessel data bases. As national and corporate interests continues in polar regions, it appears that topside icing research presently lacks the ability to quantify the topside icing threat in terms of specific vessel types. The danger presented by superstructure icing is known to exist mainly because it has caused the loss of fishing vessels almost every year. To assess the topside icing problem, a methodology is needed to estimate vessel-specific topside icing probabilities for a particular region of interest. This is particularly important when performing evaluations of ships which are larger than fishing boats since they might be less vulnerable to bow spray and ice accretion. Topside icing probabilities which account for the bow spray characteristics of particular vessels can provide improved guidance to management and assist in the direction of topside icing research and development. Ship design procedures can also be identified to reduce ice accretion through bow spray.
