FIRST ABS DEEP SEA MINING VESSEL AiP FOR CMI

Monday, January 25, 2021 

In an industry first, ABS has awarded China Merchants Industry (CMI) Approval in Principle (AiP) for its offshore deep-sea mining system design.

The AiP follows publication of the ABS Guide for Subsea Mining in October 2020 and is the first to be issued that conforms to the new Guide. CMI’s design focuses on retrieving cobalt-rich ferromanganese crust deposits attached to seamounts. The project ultimately entails development of subsea mining machines, high concentration and large particle slurry lifting systems and offshore mining support vessels.

Matt Tremblay, ABS SVP Global Offshore, said: “Demand for resources to support the low carbon economy means sustainable subsea mining will increasingly be viewed as a key technology. As the leader in offshore classification, ABS is pleased to be able use its experience to support CMI, which is taking an important step in the development of a subsea mining system and we look forward to continuing cooperation with CMI in this important field.”

“The prototype of the deep-sea mining vehicle developed by CMI was successfully tested in September on the seabed 1,300m below the South China Sea and completed the first joint operation test with a manned submersible. We really appreciate ABS support and assistance in the development of this subsea mining design,” said Xian-Fu Hu, CMI General Manager.

The ABS Guide for Subsea Mining details class requirements for the design, construction, operation, and survey of mobile offshore mining units, following global interest in resources on the sea floor  to support the emerging low carbon economy.
