REVIEW ON THE MECHANICAL PROPERTIES OF FLEXIBLE PIPE PROCESSING TECHNOLOGY IN DEEP-SEA MINING

  • 摘要: 海洋蕴藏着储量丰富的矿产资源,深海矿产资源开发逐渐成为学术界和工程界的研究热点。管道提升式开采方案是目前公认的最具商业前景的海洋矿产开发方案。矿产输运管道作为连接海底中继舱和海上采矿平台的纽带,需要承受恶劣的风、浪、流环境载荷和复杂作业工况的工作载荷,其设计制造和力学性能分析一直备受关注。相比于刚性管道,柔性管道的弯曲刚度小、便于安装与回收、使用寿命较长。然而,柔性管道的结构复杂,各层之间相互影响,金属柔性管道由于自身结构的限制,在深海采矿行业中难以广泛应用,人们开始把目光放在非金属柔性管的设计与应用上。本文回顾了柔性管的发展历程,总结阐述了柔性管设计及加工制造中的力学性能分析方法和力学特性,并对柔性管设计制造的未来发展提供力所能及的展望。

     

    Abstract: The ocean contains abundant mineral resources, and the development of deep-sea mineral resources has gradually become a research hotspot in the academic and engineering communities. The pipeline lifting mining scheme is currently recognized as the most commercially promising marine mineral development scheme. As a link between submarine relay compartments and offshore mining platforms, mineral transportation pipelines need to withstand harsh wind, wave, and current environmental loads as well as complex working conditions. Their design, manufacturing, and mechanical performance analysis have always been of great concern. Compared to rigid pipelines, flexible pipelines have lower bending stiffness, are easier to install and recycle, and have a longer service life. However, the structure of flexible pipes is complex, and the layers interact with each other. Due to the limitations of their own structure, metal flexible pipes are difficult to be widely used in the deep-sea mining industry. People have begun to focus on the design and application of non-metallic flexible pipes. This article reviews the development history of flexible pipes, summarizes and elaborates on the mechanical performance analysis methods and mechanical characteristics in the design and manufacturing of flexible pipes, and provides prospects for the future development of flexible pipe design and manufacturing to the best of our ability.
