Looks really amazing in part due to how much they spent on photographic lighting in those warehouse pics. Can you imagine how much they spent developing and building that prototype?

I'm sure there are millions of dollars spent on R&D for these giants. I wonder how they protect the hydraulics. Too large for pneumatics.

Saw a special on the natural gas pump they installed in the North Sea. Said that the compressor cost $1bil. Subsea operations cost big money. :smile:

Nice read.

One piece:
"INCO made the decision to develop their collector systems in-house and set about designing what became internally known as the “Electro-Hydraulic” (EH) collector that was subsequently patented in 1976. INCO constructed a version of the EH collector designed to be tested on a cable and scheduled a deep-sea collector test in the CCZ in the early 1970s. Unfortunately the collector, its instrumentation system, and a 7600 metre electro-mechanical tow cable were lost during a shallow water test off the coast of Oahu, Hawaii. That loss triggered INCO’s decision to search for joint venture partners leading to the formation of OMI."
