WATCH: 355-foot, 700 tonne ship flipped over

US Navy flips ship for research purposes.


FLIP (Floating Instrument Platform) is a US Navy research vessel.

It is a 355ft long, spoon-shaped buoy which can be flipped from horizontal to a vertical position by pumping seawater into the 'handle' end whilst flooding air into the 'cradle', causing it to rise up out of the sea, reveals the ship technology website (

Watch the video below to see 300 metres of the buoy submerged underwater, keeping the 700 long-ton mass steady and making it perfect for researching wave height, acoustic signals, water temperature and density, and for the collection of meteorological data.
