Conclusion of Pilot Nodule Collection System Trials

TMC subsidiary, NORI, and Allseas recently concluded integrated system trials in the NORI-D area in the Clarion Clipperton Zone (CCZ). Engineers drove the pilot collector vehicle over 80 km across the seafloor, collecting approximately 4,500 tonnes of seafloor polymetallic nodules and lifting over 3,000 tonnes of nodules up a 4.3-km riser system to the surface production vessel, Hidden Gem. The Allseas-designed and tested pilot nodule collection system — which will be scaled to include additional collector heads and a wider diameter riser pipe in preparation for NORI’s Project Zero — achieved a maximum sustained production rate of 86.4 tons per hour.
