Crawler stability and maneuverability are key performance characteristics. Safe operations require a level operational platform and constant ground contact. Equipment must be able to operate on very soft seabed conditions without imposing the risk of sinking. This has culminated in the design of a unique four
Aug 10, 2020#0183;#32;The Patania II, a 35ton tracked subsea vehicle, is a truly pioneering piece of subsea equipment. The machine is the worlds first to collect manganese nodules from the seabed at full ocean depth. For this revolutionary subsea mining crawler
Deepsea mining is the process of retrieving mineral deposits from the deep sea the area of the ocean below 200 m. Depleting terrestrial deposits and rising demand for metals are stimulating interest in the deep sea, with commercial mining imminent. The scraping of the sea floor and pollution from mining processes can wipe out entire species many yet to be discovered.
Oct 03, 2010#0183;#32;A deepsea mining operation might consist of: a mining support platform or vessel; a launch and recovery system; a crawler with a mining head, centrifugal pump, and vertical transport system; and electrical, control, instrumentation, and visualization systems.
This summer, the Government of Indias Ministry of Earth Sciences submitted an environmental impact statement for the testing of a prototype nodule mining crawler in the Central Indian Ocean Basin.
The Crawler is constructed for long term observations and long term measurements on the seafloor and for maintenancefree operation periods of up to one year. To avoid damages by the sea water the Crawler is completely made of titanium and plastic. Depending on the version the Crawler can be used in operational depths of 2000, 4000 or 6000 meters.
It will determine if and how deepsea minerals will be extracted. The development of national and international regulatory frameworks under which deepsea mining could take place is proceeding rapidly and exploration projects are under way. The International Seabed Authority (ISA) has issued 30 exploration contracts for deepsea minerals,

This summer, the Government of Indias Ministry of Earth Sciences submitted an environmental impact statement for the testing of a prototype nodule mining crawler in the Central Indian Ocean Basin. Those tests, which will be conducted in 2021, will look at both the effectiveness of the collection system and the potential environmental impacts of the process.

Oct 19, 2020#0183;#32;He is the developer of the Apollo III mining crawler, a seabed mining vehicle that has a surface area of 384 sq metres, which aims to ensure that the minerals, in De Jonges own words, can be harvested quickly and profitably. De Jonges main motivation here is mining the minerals that really matter most, he explains enthusiastically.
The riser that has to follow a seabed mining crawler presents design challenges not only in terms of water depth, but also a free hanging, untensioned state of the riser which exhibits higher motion response compared to risers that are fixed to the seabed
However development of deep subsea technology for mining these resources is a major challenge considering the ultra high pressure environment, very soft soils and other factors. NIOT has been working on a mining concept where a crawler based mining machine collects, crushes and pumps nodules to the mother ship using a positive displacement pump through a flexible riser system.
