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, un-tensioned state of the riser which exhibits higher motion response compared to risers that are fixed to the seabed. 2H have the extensive relevant experience of this type of system gained from installation engineering of deep water risers
This development is a step towards deep sea exploration, which includes the creation of a 12 tonne crawler craft to dive into the central Indian ocean to search for minerals. India intends to use this craft to mine the seabed at depths of up to 6,000m. The National Institute of Ocean Technology (NIOT) will be developing the technology. “There are 380 million tons of nodules in
Deep sea mining is a mineral retrieval process that takes place on the ocean floor.Ocean mining sites are usually around large areas of polymetallic nodules or active and extinct hydrothermal vents at 1,400 to 3,700 metres (4,600 to 12,100 ft) below the ocean’s surface. The vents create globular or massive sulfide deposits, which contain valuable metals such as silver, gold,
