Deep sea mineral product full-hose conveying offshore test system

Abstract

The invention discloses a deep sea mineral product full-hose conveying offshore test system which comprises a water surface operation platform, a flexible circulating pipe and circulating equipment, and is characterized in that the two ends of the flexible circulating pipe are fixed on the water surface operation platform, and the middle part of the flexible circulating pipe is arranged at an underwater collection depth to be tested; the flexible circulating pipe is further provided with monitoring equipment used for monitoring the state of the flexible circulating pipe, and the flexible circulating pipe is driven by the circulating equipment to lift a solid-liquid mixture at the underwater collection depth to be tested to one end located on the water surface operation platform. Then the solid-liquid mixture is conveyed to the other end of the flexible circulating pipe through circulating equipment and reaches the underwater collection depth to be tested through the flexible circulating pipe. The deep sea mineral product full-hose conveying offshore test system has the advantages of being simple in structure, easy and convenient to operate, real in test environment, reliable in test data, capable of being arranged for hose conveying and the like.

Description

technical field [0001] The invention relates to the technical field of deep-sea mining equipment testing, in particular to an offshore test system for full-hose transportation of deep-sea minerals. Background technique [0002] Metal mineral resources in the deep sea area include polymetallic nodules, polymetallic sulphides, and cobalt-rich crusts. These resources are all stored in thousands of meters of deep-seabed deposits. It is generally believed that the resource collection mode of mining vehicle mining-hydraulic lifting pipeline transportation-sea surface engineering ship has the most commercial value. At present, there are also experimental methods for hydraulic lift pipeline transportation through theoretical calculation, simulation analysis, and laboratory test research. However, these studies are all simulated or hypothetical working conditions. Due to the limitation of the test space, the length of the riser is generally only a few dozen. Meter high, it is very d...

Problems solved by technology

At present, there are also experimental methods for hydraulic lift pipeline transportation through theoretical calculation, simulation analysis, and laboratory test research. However, these studies are all simulated or hypothetical working conditions. Due to the limitation of the test space, the length of the riser is generally only a few dozen. Meter high, it is very different from offshore operations in real mining areas

And the laboratory is also in the air or deep well environment, lacking the influence of ocean waves and currents on the pipeline

[0003] Moreover, the existing test systems are all set up for hard pipe transportation, but hard pipes are difficult to arrange and retract due to their weight and connection methods. Now there are also easy-to-use and retractable hoses instead of hard pipe transportation. System trends, however no test system for hose delivery
