Summary on Grant Application Form |
|
Floating Production, Storage, and Offloading vessels (FPSOs) are an important and increasingly common form of offshore oil production system. The safety and efficiency of an FPSO under the influence of a wide range of environmental conditions is becoming an Increasingly critical factor, and relies on the accurate prediction of the extreme response of the vessel and the mooring system. Much previous work, based on second order hydrodynamic theory, has been directed at the development of analytical methods for predicting the extreme response. However, there is considerable uncertainty in some items of the input data that are required for these methods, and the effects of these uncertainties are not clear. Moreover, it has recently been found that second order hydrodynamic theory may not provide a sufficiently accurate model of the forcing, and the incident wave field may not be sufficiently Gaussian to justify the existing statistical methods. These issues will be addressed in the present project via a combination of dynamic analysis (Cambridge), CFD (University College London), and model testing (BMT and HRW). This project aims to develop improved theoretical and experimental techniques for determining the extreme response of FPSOs, with the ultimate aim of improving the safety and reliability of FPSO design and operation, and hence, the reduction in costs.
