摘要
为了解决传统船型和已有圆柱筒状FPSO的性能局限,本文提出一种具有沙漏型浮式主体的新概念FPSO。根据所研发的新型沙漏式浮体模型,确定了能够反映浮体几何形状、FPSO基本功能和水动力性能的5个相互独立的外形参数。然后,采用基于频域势流理论的边界元数值模拟方法研究了新型沙漏式浮体在波浪中的运动响应,并且定性分析了不同浮体外形参数(下倾角、水线面半径等)对浮体水动力性能的影响,得到一些有意义的结论,以期能够为新型沙漏式FPSO的主浮体外形设计提供参考依据和准则。
In order to solve the performance limitations of traditional ship-type and cylindrical FPSO,a new concept of sandglass-type FPSO is presented.For the floating body with sandglass shape,this paper presents five independent shape parameters which can not only decide the geometry of floating body but also affect the basic functions and hydrodynamic performance of FPSO.Then boundary element method based on potential flow theory is applied to analyze the motion response of sandglass-type floating body in wave.Furthermore,the influence of shape parameters(inclination angle and radius of water plane) on the hydrodynamic performance of FPSO is qualitatively studied.Finally,some meaningful conclusions are proposed to guide the shape design of new sandglass-type floating body.
