Operational capabilities of low and non-ice-class vessels in ice

为了应对人们对低冰级和非冰级船舶在开放的浮冰及其附近的作业能力日益增长的兴趣，加拿大国防研究和发展公司(DRDC)、沃德海洋公司和美国航运局(ABS)已同意与纽芬兰纪念大学(MUN)和研究开发公司纽芬兰和拉布拉多合作进行研究。这项研究将解决使现有的工程船体评估和船舶作业指导工具能够应用于低冰级和非冰级船舶(如海军近海的军舰或商船)所需的基本知识空白。将同时进行四个相辅相成的研究工作：(1)对退役的HMCS易洛魁格栅、这些格栅的新副本以及新概念格栅进行全尺寸冰锥冲击试验；(2)对新使用的CSA G40.21 260 WT钢(相当于常见的A36造船用钢)进行材料“断裂轨迹”表征；(3)开发和加强与船冰冲击有关的有限元(FE)和事件力学模拟工具；(4)开发和增强用于评估和指导低冰级和非冰级船舶在冰中的先进工程工具。这项研究的结果将：允许加拿大皇家海军(RCN)确定其军舰在冰冻水域的作战能力，从而使它们能够更好地履行在北部水域、直至北冰洋并包括北冰洋进行行动(包括搜救)的任务；为VARD在国内和国际上的行动和竞争力做出贡献，增强其服务范围，并提高其获得新的国际船舶设计合同的可能性；提高ABS对在加拿大多冰水域(例如纽芬兰和拉布拉多、圣劳伦斯海道和哈德逊湾)作业的悬挂加拿大和国际国旗的船舶进行分类的能力，从而降低在**北方的船舶运营风险，并提供更大的增加航运的可能性；开发可能商业化的新技术；并提高加拿大作为北极技术世界领导者的现有声誉。

In response to growing interest in the operational capabilities of low- and non-ice class ships in and near open pack ice, Defence Research and Development Canada (DRDC), Vard Marine Inc. and the American Bureau of Shipping (ABS) have agreed to collaborate on research with Memorial University of Newfoundland (MUN) and Research and Development Corporation Newfoundland & Labrador. This research will address the fundamental knowledge gaps needed to allow existing engineering hull assessment and ship operational guidance tools to be applied to low- and non-ice-class vessels (such as warships or commercial vessels offshore NL). Four simultaneous and complementary streams of research will be carried out: (1) full-scale ice-cone impact experiments on decommissioned HMCS IROQUOIS grillages, new copies of those grillages, and on new concept grillages; (2) material "fracture locus" characterisation of new and used CSA G40.21 260 WT steel (equivalent to the common A36 shipbuilding steel), (3) development and enhancement of ship-ice impact\ related finite element (FE) and event mechanics simulation tools; and (4) development and enhancement of advanced engineering tools for the assessment and operational guidance of low- and non-ice-class vessels in ice. The results of this research will: allow the Royal Canadian Navy (RCN) to ascertain the operational capabilities of their warships in ice-infested waters, thus enabling them to better fulfill their mandate to conduct operations (including search and rescue) in northern waters, up to and including the Arctic Ocean; contribute to the operations and competitiveness of Vard nationally and internationally, enhancing their range of services and improving their likelihood of obtaining new international ship design contracts; improve ABS's ability to class Canadian and internationally flagged ships that operate in Canadian ice-infested waters (e.g.offshoe Newfoundland and Labrador, the St. Lawrence seaway, and Hudson Bay), thereby de-risking ship operations in**the North and providing greater probability of increased shipping; develop new technologies that may be commercialized; and enhance Canada's existing reputation as a world leader in Arctic Technology.
