摘要
设计出一种新构型的半潜式钻井平台,采用数值模拟软件分析了新型平台在频域和时域的垂荡响应,并与双浮体四立柱结构和垂荡板结构的半潜式钻井平台进行了对比。介绍了新型平台的设计原理以及进行相关分析时的理论基础、数学模型和边界条件。结果表明,与双浮体四立柱和垂荡板结构平台相比,频域分析中新型平台的垂荡响应最大值和均值都显著减小;新型平台的垂荡固有周期显著增加,能有效防止共振的发生;系泊时域耦合分析中,新型平台的纵荡、横荡、横摇响应较小,且垂荡响应大幅减小;谱分析中新型平台有更小的垂荡响应谱峰值和更好的波频特性。新型平台防垂荡性能优异,结构合理、可行,可为新一代半潜式钻井平台的设计、选型提供参考。
A new type of semi-submersible drilling platform is designed. The numerical simulation software is used to analyze the heave response of the new platform in the frequency domain and time domain, and the semi-submersible drilling platforms with double-floating four-colurrm structure and heave plate structure are compared with the new platform. This paper introduces the design principles of the new platform and the theoretical basis, mathematical model and boundary conditions during correlation analysis. The numerical simulation results show that the maximum and mean values of the heave response of the new platform are significantly reduced in the frequency domain analysis compared with the double-floating four-column and the heave-plate structure platform; and the new platform has a significant increase in the natural heaving period of the new platform, which can effectively prevent the occurrence of resonance. In the mooring time domain coupling analysis, the surge, sway and roll response of the new platform is small, and the heave response is greatly reduced. In the spectral analysis, the new platform has a smaller peak response and better wave frequency characteristics. The new platform has excellent anti-heave performance, reasonable structure and feasibility, and can provide reference for the design and selection of new generation Semi-submersible drilling platform.
