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

为了应对日益增长的兴趣，低和非冰类船舶的业务能力和附近的开放式浮冰，加拿大国防研究与发展（DRDC），Vard海洋公司。和美国航运局（ABS）已同意与纽芬兰纪念大学（MUN）和纽芬兰和拉布拉多研究与发展公司合作进行研究。这项研究将解决基本的知识差距，使现有的工程船体评估和船舶操作指导工具，以适用于低和非冰级船舶（如军舰或商用船舶离岸荷兰）。将同时进行四项相辅相成的研究：（1）对退役的HMCS IROQUOIS格架、这些格架的新复制品和新概念格架进行全尺寸冰锥撞击实验;（2）新的和使用过的CSA G40.21 260 WT钢的材料“断裂轨迹”表征（3）开发和改进了船舶-冰冲击相关的有限元和事件力学仿真工具;以及（4）发展和加强先进的工程工具，以评估和指导低冰级和非冰级船舶在冰中的作业。这项研究的结果将：使皇家加拿大海军（RCN）能够确定其军舰在冰患沃茨的作战能力，从而使他们能够更好地履行其任务，进行行动（包括搜索和救援）在北方沃茨，直到并包括北冰洋;有助于Vard在国内和国际上的运营和竞争力，扩大其服务范围，提高其获得新的国际船舶设计合同的可能性;提高澳大利亚统计局对在加拿大冰雪覆盖的沃茨作业的加拿大和悬挂国际国旗的船舶进行分类的能力（例如，离岸纽芬兰和拉布拉多、圣劳伦斯航道和哈德逊湾），从而降低 ** 北部的船舶运营风险，并提供增加航运的更大可能性;开发可商业化的新技术;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.
