【摘要】 半潜生活支持平台通常配备有动力定位系统，在动力定位系统的辅助下，支持平台能够实现海上的定点控位或由远端向生产平台实施靠泊作业。由于海上的复杂作业环境，当支持平台向生产平台进行靠泊移动作业时，生产平台会受到海洋环境的影响，时刻处于运动中，这大大增加了支持平台的靠泊作业风险。为了评估支持平台的靠泊作业能力，本文建立了支持平台、FPSO生产平台以及海洋环境的数值模型。同时，设计了动力定位系统的控制算法用于控制支持平台的靠泊速度，从而确保该速度被控制在安全范围内。本文仿真结果表明，半潜生活支持平台能够在一些较为恶劣的海况下实施靠泊作业，并且所设计的控制算法能够有效地对平台的靠泊速度实施控制。更多还原

【Abstract】 A semisubmersible accommodation platform is usually equipped with a DP system. With the aid of the DP system, the platform can hold its position and go alongside offshore production platforms.Because of the complicated ocean environment, it is dangerous for the semisubmersible accommodation platform performing berthing operation while the target platform is moving. To estimate the risk of this process, the numerical models of semisubmersible accommodation platform, FPSO and ocean environment were built. Also, DP control algorithm for ensuring the semisubmersible accommodation platform to go alongside the target platform within a safe berthing speed range was designed. The simulation results show that it is feasible for the semisubmersible accommodation platform to go alongside the FPSO under some rough sea states and the speed of the platform can be effectively controlled.更多还原
