Method for Global Strength FE Analysis of the Deep-sea Mining Vessel
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.
