The Navy also has the FADOSS, though it wasn't needed here I believe. It can lift insane amounts, at insane depths. https://en.wikipedia.org/wiki/Flyaway_Deep

  -This was interesting, thanks! It appears they utilize a passive system to dampen the effect of vessel movement, whereas in many (most?) other cases compensation is done actively by the traction unit (the twin drums with the rope looped over them in the center of the photo) and the storage winch (bottom) being wired to an accelerometer installed on the vessel. I guess the navy uses the passive system as it will be good enough and does not require that you spend time figuring out the vessel geometry to input the data into the winch control system - which is just another source of problems when you're in a hurry. I like this, it seems they've made the kit as simple and robust as possible while still fulfilling its intended purpose.
