摘要/Abstract

摘要： 通过分析4种常见构型半潜钻井平台的水动力性能,为平台的选型提供全面系统的指导。1:1的三维湿表面模型使用Ansys建立,数值模拟采用水动力分析软件Aqwa (Advanced quantitative wave Analysis)。结果表明,纵浪对平台的纵、垂荡、纵摇影响较大,横浪对平台的横、垂荡、横摇影响较大;立柱数增加,纵荡、横荡、垂荡方向上的阻尼系数及附加质量和有所增加。得出了不能只考虑增加立柱数来提高平台的强度、刚度,型2平台在拖航、作业工况下都有较好的水动力性能,在设计时可以借鉴。

Abstract: To analysis of 4 semi-submersible drilling platform hydrodynamic performance providing a comprehensive guidance for system selection. The 1:1 3D wet surface model is established by ANSYS and numerical simulation is carried out based on the dynamic analysis software AQWA. Simulation results show that longitudinal waves impact the surge, heaving and pitching motion a lot, beam seas have large effects on the sway, heave, roll motion vertical heave response increases significantly, as will as surge, sway, heave damping coefficient of vector direction and the added mass coefficient of algebraic. We can not only increase the number of columns to improve platform strength and stiffness. The type 2 platform has better hydrodynamic performance, which is a reference for designing.

Key words: AQWA, emi-submersible drilling platform, frequency domain analysis, hydrodynamic properties, damping coefficient, additional quality
