Polymetallic Deep Sea Research

Project description

The Metals Company (TMC) is undertaking a comprehensive deep-sea research programme collecting polymetallic nodules from the Clarion Clipperton Zone (CCZ) in the Pacific Ocean. Successful sourcing and processing of these nodules generating almost zero solid waste could provide power for electric vehicles and other high-powered storage requirements for years to come.

Sealand, through Maersk Supply Services, have provided operational support for this research campaign, helping to facilitate the collection operations allowing time to develop an environmental basline of the proposed operating environment.

Our scope

Sealand have provided onshore engineering support in preparation the research campaigns as well as offshore operational support on board the MSS L-class vessel.

Support has included developing mobilisation & installation procedures and management of operations whilst offshore in the CCZ. Working closely with MSS and the Metals Company, Sealand have provided feedback and lessons learned on the original prototype equipment to help design upgrades for future campaigns as more is understood about sourcing the polymetalic nodules.
