Wonder if it's a horizontal version of a Proteus: http://www.reuters.com/article/pressRelease/idUS225619+07-Feb-2008+PRN20080207 "Our Proteus design continues to exceed customer specifications. We are now capable of producing Proteus systems on a mass production level. In addition to the original vertical design for lighter load applications, we can also deliver a horizontal, scaled up, higher tension version of our active heave compensation system to augment Abandon and Retrieval winches in the 50-100 ton range. We envision these Proteus units selling from $500,000 for the smaller units up to $1.5 million each for the larger applications," says Ronald E. Smith, Deep Down's President & CEO.
