    Abstract: A method for moving subsea rocks and sediments which can be at significant depths, in connection with removal of protective rocks around installations where maintenance is to be conducted. Tubing with an ejector nozzle is arranged completely externally in relation to the tubing on a standard, remote controlled submarine (ROV), so that the ejector nozzle produces a pressure gradient through the tubing. An inlet end of the tubing is located with the rocks and sediments to be moved, which are sucked into the tubing and blown out of the opposite end of the tubing.
