浮冰对船舶和海洋结构物动力特性的影响取决于许多因素，如冰层厚度及其相对于浮式结构物的相对速度。冰对船舶运动的阻力是船舶设计和航行中的一个重要问题。此外，局部或全球的冰载荷作用在海洋系统的随机和非光滑的碰撞相互作用时，发生。在固体冰中航行的船的船首上的冲击载荷可以用泊松定律来模拟。在船体首段测得的应力幅值服从指数分布。冰的微观结构的不均匀性和差异性，以及盐和温度的影响，导致冰的强度有很大的不确定性。因此，本综述文章旨在评估海洋结构物以及船舶在航行过程中遇到的与冰有关的问题。它还讨论了当地和全球冰荷载对浮式结构物的影响，并回顾了现有的概率模型。此外，本文还讨论了冰与柔性和刚性结构以及船舶的动力相互作用。考虑到海洋系统上的冰载荷，参与船舶以及海上结构物的设计和建造的国际组织已经引入了新的设计规则。船舶随机稳定性和第一通道横摇稳定与随机海浪的问题也将被描述，试图刺激未来的研究工作处理冰冲击载荷。此外，由于缺乏研究活动，解决船舶在冰冷的沃茨中运行的控制问题，本文将简要讨论被动和主动控制方案控制船舶横摇运动。本文共引用参考文献529篇。
The influence of floating ice on the dynamic behavior of ships and offshore structures depends on many factors such as ice thickness and its relative speed with respect to the floating structure. The ice resistance to ship motion forms an essential problem in ship design and navigation. Furthermore, local or global ice loads acting on ocean systems are random and nonsmooth when impact interaction takes place. Impact loads on the bow of a ship navigating in solid ice may be modeled by a Poisson law. The measured stress amplitudes on the ship frame at the bow follow an exponential distribution. The nonhomogeneity and difference in ice microstructure, as well as the influence of salt and temperature, result in a great uncertainty in the ice strength. Therefore, the current review article aims at assessing the ice related problems encountered by offshore structures as well as by ships during their navigation. It also discusses the impacts of local and global ice loads on floating structures and reviews their existing probabilistic models. Moreover, this article covers the dynamic interaction of ice with flexible and rigid structures, and ships. In view of ice loads on marine systems, new design regulations have been introduced by international organizations that are involved in the design and building of ships as well as offshore structures. The ship stochastic stability and the first-passage roll stabilization problem associated with random ocean waves will also be described in an attempt to stimulate future research work dealing with ice impact loads. Moreover, due to the lack of research activities addressing the control problem of ships operating in icy waters, the current article will briefly discuss passive and active control schemes developed for controlling the ship roll motion.
