水下机器人ROV(remote operated vehicle)工具篮子用于在陆地和深海中储存ROV安装工具,除方便ROV进行操作外,同时给ROV工具提供保护,能够很好地适应深远海环境,是水下生产系统的重要组成部件.其深海安装作业风险高、要求严,研究其安装全过程工况的强度性能对确保整个水下生产系统平稳运行具有重要作用.针对南海陵水气田使用的ROV工具篮子深海多种典型工况,计算得到设计载荷,然后对其进行有限元建模分析,计算不同载荷工况下的应力响应,对结构的屈服强度进行校核,以确保整体结构强度满足安全规范要求.计算结果表明:ROV工具篮子在多种提升工况、冲击工况以及运输工况下结构屈服强度均满足规范要求,在此基础上,指导现场使用的ROV工具篮子设计,整个海上安装及水下运行安全可靠.研究成果可为ROV工具篮子以及类似水下结构物的结构设计和深海安装提供理论基础和技术参考.
Design Load and Yield Strength Analysis of Deepwater ROV Deployment Basket Structure
Remote operated vehicle(ROV)deployment baskets are used to store ROV installation tools on land and in the deepwater.In addition to the convenience of ROV operation,it also provides protection for ROV installation tools,which can be well adapted to the far-reaching sea environment,and is an important component of subsea production system.Its deepwater installation operation has high risks and strict requirements,so it is important to study its strength performance in the whole installation process to ensure the smooth operation of the whole subsea production system.Based on a variety of typical deepwater working conditions of ROV deployment basket used in Lingshui water gas field of the South China Sea,the design load was calculated,and then the finite element modeling analysis was carried out to calculate the stress response under different load conditions,and the yield strength of the structure was checked to ensure that the overall structural strength met the safety requirements.The calculation results show that the structural yield strength of the ROV deployment basket meets the specification requirements under various lifting conditions,impact conditions and transportation conditions.On this basis,the design of the ROV deployment basket used on site is guided,and the whole offshore installation and underwater operation are safe and reliable.The research results can provide theoretical basis and technical reference for the structural design and deepwater installation of ROV deployment baskets and similar underwater structures.
