Global Sea Mineral Resources (GSR), the deep‑sea exploratory subsidiary of DEME, has entered into a memorandum of understanding (MOU) with Deep Ocean Resources Development (DORD) of Japan to conduct a joint demonstration test aimed at the potential co-development of polymetallic nodule resources within DORD’s exploration license area in the Clarion‑Clipperton Zone in the Pacific Ocean.
Under the MOU, GSR will provide its technical knowledge and operational expertise to support DORD’s program.
A key objective of the partnership is the execution of a system integration test (SIT) in the early 2030s within the DORD contract area. DEME said this test will validate the safe and reliable operation of an integrated commercial‑scale mining system – including a seafloor collector, vertical transport system and surface vessel – at depths exceeding 4,000 metres.
The SIT will include a comprehensive environmental impact assessment, combining GSR’s offshore operational experience with DORD’s extensive environmental and geological dataset built up over decades of exploration work in the area.
All activities carried out under the MOU will take place within the DORD license area and will comply fully with the International Seabed Authority’s exploration regulations and environmental guidelines.
