摘要
以某深水半潜式钻井平台为例,建立平台和推力系统模型,对风、浪、流环境载荷作用下的动力定位系统进行时域模拟,得到平台的运动时历和功率消耗,对平台动力定位的实时功率进行研究。为了验证数值计算的准确性,开展相关模型试验研究。旨在借助时域模拟来分析平台动力定位实时功率,通过模型试验来验证数值计算,检验了动力定位时域模拟的可靠性和优越性,为以后工程实际应用提供了重要的理论依据。
This paper takes a deep sea semi-submersible drilling platform as an example, makes time domain simulation for dynamic positioning system, achieves time series of the displacement and consumed power of the platform and conducts researches on real-time power simulation. To verify numerical simulation, dynamic positioning model test is conducted. The computed results agree well with test data, which indicates this method is available. This paper is aimed to study real-time simulation of dynamic positioning, verify re- sults of calculation by model test, summarize the reliability and superiority of time domain simulation and provide important theoretical bases for engineering application in the future.
