DEME subsidiary GSR receives Transocean investment

DEME Group NV (Euronext Brussels: DEME) today announced a strategic cooperation with Transocean Ltd. (NYSE: RIG) that brings together DEME’s Global Sea Mineral Resources’ (“GSR”) leadership in ultra-deepwater mineral exploration and seafloor nodule collection technology with Transocean’s world-class offshore expertise and capabilities.

As part of its investment, Transocean is contributing the vessel ‘Ocean Rig Olympia’ for GSR’s ongoing exploration work, a cash investment and engineering capacity. In return, Transocean is receiving a minority stake, including a board seat, in GSR. Following the successful trial of GSR’s pre-prototype seafloor nodule collector in 2021 at 4500m water depth, a key task ahead for GSR is a system integration test (“SIT”), scheduled for 2025. The SIT – for which the converted ultra-deepwater vessel shall be instrumental – will entail a trial of a full-scale seafloor nodule collector and riser to lift the nodules to the surface vessel and is part of GSR’s step-by-step and precautionary approach to project and technology development as the company explores the feasibility of commercial operations.

“Transocean is a leader in the global offshore drilling industry and is well known for its ultra-deepwater expertise. We are proud to be working with them as we further explore the potential of deep seabed minerals, which may represent a better way of meeting future metal demand and expand diversity of supply. Critical metals, such as nickel, cobalt, copper, and manganese – found in polymetallic nodules – are key ingredients for a low-carbon future. Deep-seabed mining certainly won’t replace land-based mining entirely, however, according to peer-reviewed scientific literature, these metals could be delivered with a 40% reduction of the carbon footprint, which is essential when combating climate change.”, said Kris Van Nijen, Managing Director of GSR.

Chief Executive Officer Luc Vandenbulcke of DEME Group said: “Since the International Energy Agency reported that society will need six times more metals by 2040 to become a net-zero society in 2050, there have been many national initiatives to secure the necessary supply of raw materials. From the U.S. Inflation Reduction Act, the Australian & Canadian Critical Minerals Strategy to the EU Critical Minerals Act, society is now fully aware of the geopolitical and environmental risk of the clean energy transition. As a result, the development of marine minerals has gained considerable momentum to help supply the responsible minerals needed to meet demand due to increased population, urbanization, and transition to a clean energy future and circular economy. Both DEME and Transocean plan to play an important role in the development of a responsible deep seabed minerals sector.”
