基于蒙特卡洛模拟的半潜式平台极限强度可靠性研究
Reliability of Semi-Submersible Platform's Ultimate Strength Based on Monte Carlo Simulation
摘要
Abstract
Semi-submersible platform is the major equipment in deep sea drilling, and its design and construction techniques are essentially applicable to the environment of the South China Sea. Ultimate strength of the structure represents the limit load it can bear, thus giving full consideration to the uncertainties of ultimate strength has great significance to structure safety. Smith Method was used to calculate the ultimate strength of the semi-submersible platform in this paper, and uncertainties of the ultimate strength were listed with the type of distribution and the characteristic parameters. Monte Carlo Method quantized the uncertainties and the probability density curves of the ultimate strength were obtained through cycle calculations. Study results show that the uncertainties of the structure have great impact on the ultimate strength and the nominal value of the ultimate strength could not truly reflect the bearing capacity of semi-submersible platform.关键词
