NORI and Allseas Lift Over 3,000 Tonnes of Polymetallic Nodules to Surface from Planet's Largest Deposit of Battery Metals, as Leading Scientists and Marine Experts Continue Gathering Environmental Data

15.11.2022
The Metals Company, an explorer of the world’s largest estimated undeveloped source of critical battery metals, announced that its subsidiary NORI and offshore partner Allseas have successfully concluded the first integrated system test in the Clarion Clipperton Zone of the Pacific Ocean since the 1970s, achieving all significant pilot milestones while collecting approximately 4,500 tonnes of seafloor polymetallic nodules. Over 3,000 tonnes were transported up a 4.3km-long riser system to the surface production vessel, Hidden Gem, while the additional 1,500 tonnes of nodules were purposely left behind on the seafloor as part of the trials.

TMC and Allseas Achieve Historic Milestone: Nodules Collected from the Seafloor and Lifted to the Production Vessel Using 4 km Riser During Pilot Trials in the Clarion Clipperton Zone for First Time Since the 1970s

12.10.2022
TMC the metals company Inc., an explorer of the world’s largest estimated undeveloped source of critical battery metals, today announced that it has successfully collected an initial batch of seafloor polymetallic nodules, and transported them up a 4km-long riser system to the surface, in what represents the first integrated system test conducted in the Clarion Clipperton Zone of the Pacific Ocean since the 1970s.

The Metals Company and Allseas Announce Successful Deep-Water Test of Polymetallic Nodule Collector Vehicle in the Atlantic Ocean at a Depth of Nearly 2,500 Meters

06.05.2022
TMC the metals company Inc., an explorer of the world’s largest estimated undeveloped source of critical battery metals, today announced the successful completion of initial deep-water trials of the polymetallic nodule collector vehicle in the Atlantic Ocean. Engineers successfully lowered the Allseas-designed collector vehicle to the seafloor at depths of 2,470 meters, marking the first time the vehicle had been subjected to ultra-deep-water temperatures and pressures. Engineers then subjected the vehicle to extensive testing of its various pumps and critical mobility functions, driving 1,018 meters across the seafloor.

The Metals Company and Allseas Announce Successful North Sea Drive Test of Pilot Nodule Collector Vehicle

08.04.2022
Following earlier harbor wet-testing, the Allseas-designed pilot nodule collector vehicle was deployed from the Hidden Gem and lowered to the seafloor in open sea conditions. A range of critical drive functions were successfully tested, confirming the collector’s capability to manoeuvre forwards and backwards at various speeds and in different directions, as well as to lower and raise the nodule collector heads.

Allseas Selects Seatools for Deep-sea Mining Equipment

04.03.2021
Allseas has awarded subsea technology company Seatools the contract for the delivery of the complete electrical, hydraulic, and control system for Allseas’ deep-sea mining nodule collector. The project is part of Allseas’ development program to realize advanced deep-water equipment for the gathering of polymetallic nodules from the ocean floor in a responsible way.
