摘要
为了解深海采矿船在位工况时环境载荷作用下的全船结构响应状态,选取合理的装载工况和波浪特征载荷,基于三维势流理论,对波浪载荷响应进行数值分析,确定设计波载荷并进行总强度计算.结果表明,根据《深海采矿设施指南》,以及CCS、ABS、BV的其他相关规范,可以形成一套可供参考的深海采矿船总强度分析的方法及要求;深海采矿船结构设计应重点关注月池及其相连结构、货舱区纵向桁材向舱壁的过渡结构,以及货舱区角隅等结构区域.
Abstract
In order to understand the structural response state of deep-sea mining ship in the on-site condition,the reasona-ble loading conditions and wave characteristic loads were selected;based on the three-dimensional potential flow theory,the wave load responses were analyzed.The design wave load was determined to assess the global strength.The results showed that a set of reference methods and requirements for the global strength analysis of deep-sea mining vessels can be established according to Guidelines for Deep-sea Mining Facilities and other relevant rules of CCS,ABS and BV.The structural design of deep-sea mining vessel should focus on the moon pool and its connecting structures,the transition structures from longitudinal girder to bulkhead in the cargo hold area and the corners of the cargo hold area.
