A buoyant element comprising a rigid envelope 52 defined by a pipe, the envelope defining an internal chamber that contains a mass of buoyant macrospheres 10 each with an external diameter of at least 5mm, packed with a packing factor of at least 50%. There may be voids between the macrospheres in the mass in fluid communication with one or more openings 56 that penetrate the envelope. The macrospheres may be packed around, or beside at least one insert 66 that supports at least one barrier 74 that subdivides the chamber to constrain the movement of the macrospheres within the chamber.
