Fluid-Structure Analysis of Very Large Floating Structures

该项目涉及超大型浮动结构（VLFS）的理论和实验流体结构分析。该计划的主要目标是提高对 VLFS 响应的理解和预测能力。 这项工作的一个主要方面是对 6 个比例模型 VLFS 进行波池模型测试。 从这些测试中获得的数据不仅包括基本的运动响应，还包括水弹性响应的详细描述。 这些数据将用于验证数值技术并识别和评估数值模型中未包含的现象。 将开发和完善用于预测水弹性响应的新的和现有的数值技术，重点放在适用于大规模、灵活的浮动系统的方法上。 实验数据和数值模型将用于评估各种配置并制定通用设计指南。 VLFS 的规划尺寸可能约为 1,000x 3,000 m，与现有浮标相比，尺寸大幅增加。 由于不存在可比较的现场数据和经验，因此需要进行这项研究以更好地了解 VLFS 的水弹性响应。 它必须在 VLFS 的设计和建造之前进行。

This program involves the theoretical and experimental fluid-structure analysis of very large floating structures (VLFSs). The primary objective of the program is to improve the understanding of VLFS response and the capabilities to predictit. A major aspect of the work involves wave tank model testing of six scale model VLFSs. Data obtained from these tests will include not only basic motion response, but a detailed description of the hydroelastic response. The data will be use to validate numerical techniques and to identify and evaluate phenomena not included in the numerical models. New and existing numerical techniques to predict the hydroelastic response will be developed and refined, with an emphasis placed on methodologies appropriate for large scale, flexible, floating systems. The experimental data and numerical models will be used to evaluate various configurations and to develop general guidelines for design. A VLFS might have plan dimensions on the order of 1,000x 3,000 m, which is a substantial increase in size compared to existing floaters. Because comparable field data and experience is nonexistent, this research is required for the better understanding of the hydroelastic response of VLFSs. It must be carried out prior to the design and construction of a VLFS.
