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

为了满足人们对浮冰内及附近低冰级和非冰级船舶作战能力日益增长的兴趣，加拿大国防研究与发展局 (DRDC)、Vard Marine Inc. 和美国船级社 (ABS) 已同意与纽芬兰纪念大学 (MUN) 和纽芬兰与拉布拉多研究与发展公司合作开展研究。这项研究将解决现有的工程船体评估和船舶操作指导工具应用于低冰级和非冰级船舶（例如荷兰近海军舰或商船）所需的基本知识差距。将同时进行四个互补的研究流：（1）对退役的 HMCS IROQUOIS 格栅、这些格栅的新复制品以及新概念格栅进行全尺寸冰锥冲击实验； （2）新旧CSA G40.21 260 WT钢（相当于普通A36造船钢）的材料“断裂轨迹”表征，（3）船冰冲击\相关有限元（FE）和事件力学模拟工具的开发和增强； (4) 开发和增强先进的工程工具，用于冰区低冰级和非冰级船舶的评估和操作指导。这项研究的结果将：使加拿大皇家海军（RCN）能够确定其军舰在冰雪覆盖水域中的作战能力，从而使他们能够更好地履行在北部水域（包括北冰洋）开展行动（包括搜救）的任务；为 Vard 在国内和国际上的运营和竞争力做出贡献，扩大其服务范围并提高获得新国际船舶设计合同的可能性；提高 ABS 对在加拿大冰雪覆盖水域（例如离岸纽芬兰和拉布拉多、圣劳伦斯航道和哈德逊湾）运营的加拿大和国际国旗船舶进行入级的能力，从而降低**北部船舶运营的风险，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.
