研究了船舶在冰压下陷入困境的风险。冰动力学的事后分析检查了导致2005年3月9日在圣劳伦斯湾两艘船只被困的条件。分析检查潜在的重要变量的分布，如压力（平均正应力），脊厚度和应变率。然后提出了一个评估围攻风险的标准。还进行了初步的参数研究，以说明在不同的冰和环境强迫条件下预测困扰的风险的方法。
The risks of ship besetting under ice pressure are examined. Hindcasts of ice dynamics examine the conditions that led to the besetting of two vessels in the Gulf of St. Lawrence on 9 March 2005. The analysis examines the distributions of potentially significant variables such as pressure (mean normal stress), ridge thickness and strain rates. A criterion for assessing the risk of besetting was then proposed. A preliminary parametric study was also done in order to illustrate a method for predicting the risk of besetting under different ice and environmental forcing conditions.
