Abstract
Method and device for moving subsea rocks and sediments, particularly at significant depths, for example in connection with removal of protective rocks around subsea installations where maintenance is to be conducted. The device includes a rigid or at least partly flexible tubing thorough which masses may be transported with the aid of a pressure gradient produced by an ejector nozzle arranged externally in relation to the tubing, and fed with water from a water pump. The device further includes a chassis adapted to be transported along the sea bottom. The required power is supplied through a cable from the surface, while the tubing preferably is remotely controlled by a manipulator.
