KNVTS lecture: A precautionary approach to developing nodule collector technology

March 17 @ 19:30 - 22:00

The basis of GSR’s research and development (R&D) strategy was developed in 2013 following a desktop study which defined an integrated concept of operation.

A key component of the deep seabed mining system is the Seafloor Nodule Collector (SNC). The SNC has a significant influence on the overall operational environmental impact and on the achievable production rate, two criteria that are critical in developing a responsible mining operation. Additionally, given commercial deep-seabed mining operations are unprecedented, the SNC is the sub-system involving the highest number of information and knowledge gaps, such as the environmental impacts and effects, its response to soil characteristics, trafficability and nodule collection methodology.

Hence, from all the systems identified, GSR decided to focus its first efforts on the SNC system and more specifically on a pre-prototype of a SNC. This feasibility study consisted of a step-by-step approach and culminated in the design, building and testing of a pre-prototype SNC, called Patania II (PATII).

Following the successful trials conducted with Patania II at 4,500 m water depth in the CCZ in 2021, the final phase will commence, which will culminate in a trial of a commercial-scale SNC. GSR remains committed to responsible deep-sea research and technology development, one step at a time.
