摘要
对于较深水海域导管架多采用滑移下水的安装方式,下水分析的目的是在导管架和驳船确定的情况下,选择合理的下水初始状态,以得到一个安全的下水过程。结合某深水导管架滑移下水设计实例,采用三维分析软件MOSES,依据Noble Denton规范,对驳船在下水初始状态的吃水和倾角进行了敏感性研究。分析下水过程中初始参数变化对驳船摇臂反力、导管架最大下潜深度以及二者相对运动速度的影响,对导管架滑移下水分析具有一定的指导意义。
Most deep water jackets are installed by sliding launch. Based on the determination of jacket and selected launch barge, launching analysis aims to obtain a safety launching operation by identifying reasonable initial barge condi- tion. According to Noble Denton guideline, this paper makes a sensitive research about initial barge draft and trim angle by using 3D marine analysis software MOSES. The research mainly focuses on the influence of reaction force on barge rocker arm, jacket maximum submerge depth and relative speed between the jacket and the barge. The research results are useful for launching analysis.
