jk - agreed, that quote refers to winches already being used by a customer for which active-heave-comp (AHC) can be added. That broadens the market for DDI since, in addition to the full fledged Proteus (which would come with a winch), they can provide an add-on AHC capability to existing winches. I have no idea what the life span is, of these things. There have been AHC winches out there in the market for a while. However, the Proteus does seem to set the bar higher in terms of capability/precision etc.
