ABSTRACT

Design and fabrication procedures used in spherical pressure hull construction have been described in this paper. An appropriate design standard has been applied to ensure the safety and reliability of the pressure hull. Considering the material and manufacturing facility available, steel has been chosen as the pressure hull material. Design and manufacturing of spherical pressure hull have been carried out using ASME PVHO-1 and finite element analysis is used for full model analysis and verification. The manufacturing process is followed as per the approved quality assurance procedure. The spherical pressure hull has been tested for the reduced test diving depth of 189 m at sea. After the test, it is observed that there is no physical damage and no leakage. The same pressure hull can be used for further studies in the shallow water depths.

摘要

本文介绍了球形耐压船体结构中使用的设计和制造程序。已采用适当的设计标准来确保耐压壳的安全性和可靠性。考虑到可用的材料和制造设备，选择钢作为耐压船体材料。采用ASME PVHO-1进行球形耐压船体的设计和制造，并采用有限元分析进行全模型分析和验证。按照批准的质量保证程序遵循制造过程。球形耐压船体已在海上进行了 189 m 的减少测试潜水深度测试。测试后，观察到没有物理损坏，也没有泄漏。相同的耐压船体可用于浅水深度的进一步研究。
