Improving shock resistance of marine structures

我的研究计划的最终目标是引入海洋结构的新设计，这些结构比目前使用的结构更安全，因为它们可以更好地承受意外和人为水下爆炸引起的冲击波。实现这一目标将使我们在沿海沃茨的作业更加安全，并将有助于更好地保护成千上万在海上平台和船舶上谋生的加拿大人的生命。 同样重要的是，涉及海洋结构物的事故后果通常非常严重，往往对环境造成有害和长期的影响。 引入更抗震的海洋结构将减少与海上工业相关的环境风险，从而有助于保护我们的自然环境并为子孙后代保护它。“深水地平线”石油钻井平台爆炸以及随后的石油泄漏造成了巨大的环境破坏，这清楚地表明，迫切需要更安全、更防爆的海洋结构。这里提出的研究倡议将有助于使这种新颖的结构成为现实。 拟议的研究倡议将在新斯科舍省哈利法克斯的达尔豪西大学进行。哈利法克斯造船厂最近获得了一份价值250亿美元的合同，为加拿大海军建造战斗舰，达尔豪西大学是一个特别适合进行拟议中的研究计划的地方，原因有二。首先，如此重要的造船厂的邻近将使我的研究计划对最先进船舶的设计和制造产生更快、更直接的影响。其次，参与一个与工业直接相关的研究项目对潜在的研究生来说非常有吸引力，从而使我能够招募到最好的研究人员。 我已经介绍了一些有希望的水下结构物的减震设想。我将以它们为基础，改进现有的海洋系统，以确保它们具有上级抗爆炸能力，从而提高它们的生存能力。因此，我将提供新颖的海洋结构设计，这将提高我们的海上工业和海军的安全。 这种新的设计将提供结构性的安全改进，这将在结构的使用寿命内24/7有效。因此，与执行业务安全措施所需的大量资源相比，它们的费用相对较少。因此，我建议的研究计划的成功不仅会导致开发新技术，而且还会节省成本。此外，它将有助于推进流体和结构之间相互作用的知识，这对当今工程的许多领域都具有重要意义。

The ultimate goal of my research program is to introduce novel designs of marine structures that are safer than the structures currently used in that they can better withstand shock waves caused by underwater explosions, both accidental and man-made. Accomplishing this goal will make operating in our coastal waters safer and will contribute to a better protection of the lives of the thousands of Canadians that earn their living working on offshore platforms and ships. Not less importantly, the consequences of accidents involving marine structures are usually very grave, and often have detrimental and long-term environmental impacts. Introducing more shock-resistant marine structures will reduce the environmental risk associated with the offshore industry, thus contributing to protecting our natural environment and preserving it for future generations. The explosion at the Deepwater Horizon oil rig and the subsequent oil spill that caused the environmental damage of epic proportions are a clear indication of the immediate need for safer, more explosion-resistant marine structures. The research initiative proposed here will contribute to making such novel structures a reality. The research initiative proposed will be carried out at Dalhousie University, Halifax, Nova Scotia. With the Halifax Shipyard recently awarded a $25 billion contract to build combat ships for the Canadian Navy, Dalhousie University is a particularly suitable place to undertake the proposed research program, for two reasons. First, the proximity of such a major shipbuilding operation will allow for a faster, much more direct impact of my research program on designing and manufacturing of state-of-the-art ships. Second, being involved in a research project with such a direct industrial relevance will be very attractive to potential graduate students, thus allowing me to recruit the best research personnel available. I have already introduced a number of promising shock-reduction ideas for submerged structures. I will use them as a foundation for modifying the existing marine systems in ways that will ensure their superior resistance to explosions, thus providing their improved survivability. As a result, I will deliver novel designs of marine structures that will improve the safety of our offshore industry and navy. Such new designs will provide constructive safety improvement which will be in effect 24/7 for the lifetime of a structure. Thus, they will incur relatively little cost, as opposed to the considerable resources required for implementing operational safety measures. Therefore, the success of the research program I am proposing will not only lead to developing new technology but will also result in cost savings. Furthermore, it will contribute to advancing the knowledge of the interaction between fluids and structures, something that is of significant importance to many areas of engineering today.
