Special Issue Information

Dear Colleagues,

There are large amounts of resources, including metal sulfides, polymetallic nodules, cobalt rich crusts, etc., located in the international seabed from 2000m to 6000m; however, the difficulty of mining is extremely high and has not been fully resolved. The first Deep Sea Mineral Resources Youth Academic Forum will be held in Yazhou Bay, Sanya, from January 9th to 11th, 2025, jointly hosted by China University of Petroleum (Beijing) and Changsha Institute of Mining and Metallurgy Co., Ltd. The conference will cover relevant technologies in the fields of exploration, collection, environment, and metallurgy of deep-sea mining, helping to comprehensively achieve integrated sea trials of deep-sea mining linkage and effectively promote the commercial exploitation of deep-sea mining. We welcome colleagues to explore green, efficient, reliable, intelligent, and safe deep-sea mineral mining technologies together; to discuss scientific issues and key technologies in deep-sea mining exploration, collection, and mixed transportation; to jointly plan a deep-sea mining environmental monitoring and evaluation technology system; comprehensively promote the high-quality development of deep-sea mineral exploration, mining, environment, and metallurgical full-chain technology; and provide intellectual, technological, and core domestic equipment support for the mining of international mining areas.

Therefore, we invite you to submit your paper to this Special Issue, whose coverage is consistent with the theme of this conference. Contributions from authors that include, but are not limited to, the following areas are welcome:

  • Multiphase flow-induced vibration of deep-sea mining risers
  • Vortex-induced vibration of deep-sea mining risers
  • Structural health monitoring of deep-sea mining facilities
  • Regulations, policies and economic evaluation of deep-sea mineral resources development

  • Deep-sea mining vessels and the surface support platform
  • Precise exploration technology and equipment for deep-sea mineral resources
  • Deep-sea mining vehicles (polymetallic tuberculosis, sulfide, cobalt-rich crust, deep-sea rare earth)
  • Deep-sea mineral resources mixed transport system (hydraulic lifting pump, pneumatic lifting, etc.)
  • Intelligent diagnosis, monitoring and control of optical fiber for deep-sea mineral resources
  • Power transmission and distribution of deep-sea mineral resources
  • Sub-sea exploration and ROV of deep-sea mineral resources
  • Deep-sea mineral resources equipment deployment and recycling
  • Geology and environmental protection of deep-sea mineral resources
  • Deep-sea mineral resources, rocks and soil mechanics
  • Monitoring and evaluation of plume influence of deep-sea mineral resources and environment
  • Safety technology and evaluation of deep-sea mineral resources and equipment
  • Beneficiation technology of deep-sea mineral resources

As terrestrial resources become increasingly scarce, the exploration and utilization of marine resources have become crucial for ensuring a stable resource supply. A maritime A-Frame is a specialized lifting mechanism mounted on the stern of a vessel, designed for deploying and retrieving heavy loads during subsea exploration. Real-time monitoring of the stress of A-Frames is essential for identifying potential failures and preventing accidents. This paper presents a stress-monitoring campaign conducted on a maritime A-Frame during a deep-sea mining project in the South China Sea. Fiber Bragg Grating (FBG) strain sensors were installed on the A-Frame to measure its stress responses throughout the deep-sea mining operation. The stress variations observed during the deployment and retrieval of a deep-sea mining vehicle were analyzed. The results indicate that the stress caused by the swinging motion of the A-Frame was significantly higher than that generated by the lifting and deployment of the mining equipment. Additionally, a finite element model (FEM) of the A-Frame was developed to estimate the stress of the hot spots by integrating the measured strain data. The analysis confirmed that the maximum stress experienced by the A-Frame was well below the allowable threshold, indicating that the structure had sufficient strength to withstand operational loads. In addition, the swing angle of the A-Frame significantly affects the stress value of the A-Frame, while lifting the mining vehicle has a very slight effect. Thus, it is advisable to accelerate the deployment and retrieval speeds of the mining vehicle and minimize the outward swing angle of the A-Frame. These findings provide valuable insights for optimizing the design and ensuring the safe operation of maritime A-Frames in deep-sea mining exploration. Full article

The development of heave compensation systems in marine engineering and deep-sea mining applications is analyzed, and their functional requirements and key features are summarized. Based on this analysis, a system is proposed that uses flexible joints to compensate for pitch and roll motion, along with a single-chamber valve-controlled compensation cylinder with a high-pressure accumulator to compensate for heave motion. An active heave compensation system based on this design is studied using a fuzzy PID control method. A dynamic model of the system is then established for this control system. Numerical simulations are carried out to evaluate the control process and performance under different sea conditions. The results show that the proposed heave compensation system offers distinct advantages such as a simple and compact structure, minimal deck space requirements on the mining vessel, and large compensation angles for both pitch and roll. Furthermore, the use of a fuzzy PID control method for heave compensation achieves a relatively good compensation effect, and can be adapted to varying sea conditions. Full article
