<p>A floatation device (100) is provided comprising a buoyancy chamber (110); a cryogen reservoir (210); and a heating pipe (310) providing switchable fluid communication between the cryogen reservoir (210) and the buoyancy chamber (110). A method of raising an item from the seabed is also provided. The method comprising the steps of lowering a floatation device (100) to the seabed; attaching the floatation device (100) to the item to be raised; creating a supercritical fluid within a portion of the floatation device (100); and allowing the floatation device (100) and the item to rise to the surface using the buoyancy of the supercritical fluid to raise the item to the surface.</p> |
