Abstract
A method and a buoyancy device adapted to impart buoyancy to at least one longitudinal element submerged in water. The buoyancy device is hollow and is preferably made of plastic or a similarly corrosion-resistant material. The device is preferably produced as one single unit, but may include several separate chambers which, via valves, may be brought into communicating connection with the surroundings, in a controlled manner. The device will therefore not be subjected to large differential pressures in use, and accordingly may have relatively thin walls. The buoyancy device has a much lower weight than prior-art buoys, is simpler to assemble, and is not subject to corrosion.
