How the first floating liquefied natural gas project will work

The video tutorial explains the process of seabed mining between Hawaii and Mexico. It describes the deployment of a support vessel and a subsea mining vehicle, known as a crawler, which extracts polymetallic nodules from the seabed. These nodules are rich in rare earth elements and valuable metals like cobalt, manganese, nickel, copper, and aluminum. The crawler is designed to withstand extreme conditions and transports the extracted materials to the surface via an umbilical hose. The video highlights the technical aspects of the mining process and the composition of the nodules.
