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.

我的研究计划的最终目标是引入新的海洋结构设计，这些结构比目前使用的结构更安全，因为它们能够更好地抵御水下爆炸引起的冲击波，无论是意外爆炸还是人为爆炸。实现这一目标将使我们沿海水域的作业更加安全，并将有助于更好地保护在近海平台和船只上工作谋生的数千加拿大人的生命。 同样重要的是，涉及海洋结构物的事故的后果通常非常严重，往往具有有害和长期的环境影响。引入更耐冲击的海洋结构将减少与近海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的爆炸和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、更耐爆炸的海洋结构。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。 拟议的研究计划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授予了一份价值250亿美元的合同，为加拿大海军建造战舰，达尔豪西大学是开展拟议中的研究项目的特别合适的地方，原因有两个。首先，如此大型造船业务的临近将使我的研究计划对最先进的船舶的设计和制造产生更快、更直接的影响。其次，参与这样一个与行业直接相关的研究项目将对潜在的研究生非常有吸引力，从而使我能够招聘到可用的最好的研究人员。 我已经介绍了一些有希望的水下结构减震想法。我将把它们作为修改现有海洋系统的基础，以确保它们具有卓越的抗爆能力，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，以改善我们近海工业和海军的安全。 这种新的设计将提供建设性的安全改进，这将在结构的整个生命周期内24/7有效。因此，它们的成本相对较低，而实施业务安全措施则需要相当多的资源。因此，我提议的研究计划的成功不仅将导致新技术的开发，还将导致成本节约。此外，它将有助于提高对流体和结构之间相互作用的知识，这对当今许多工程领域具有重要意义。
