半潜支持平台与FPSO靠泊运动频域水动力性能研究

Study on Hydrodynamic Performance of Berthing Motion between Semi-submersible Support Platform and FPSO in Frequency Domain

以北海型和标准型2型深水半潜式支持平台为载体,某32万吨级FPSO为靠泊对象,利用AQWA软件进行频域水动力计算。分别分析2型支持平台与FPSO浮体间的相互作用对支持平台的影响,同时研究不同靠泊方向、间距、靠泊对象吃水变化、浪向角等因素对水动力参数的影响。研究得到频域下的水动力参数变化规律,为支持平台与FPSO的靠泊设计提供参考。

Taking 2 types of North Sea type and standard type deepwater semi-submersible support platforms as carriers and a 320000 DWT FPSO as berthing object,the hydrodynamic calculation in frequency domain is carried out by AQWA software.The influence of interaction between the two types of support platforms and FPSO floating body on the supporting platform is analyzed respectively.At the same time,the effects of the factors such as different berthing directions,spacing,draft variation of berthing objects and wave direction angle of the supporting platform on the hydrodynamic parameter are studied.The changing laws of the hydrodynamic parameters in frequency domain are gained,which provides reference for the berthing design of supporting platform and FPSO.
