Abstract (en)
[origin: WO9966616A1] The invention relates to an arrangement (1) for passing one or more cables (2) through a cable-enclosing duct with the aid of pressurised liquid (water) (4), wherein the relative density of the cable (2) is chosen to correspond to or at least essentially to the relative density of the liquid (4) used, said pressurised liquid being permitted to pass through said duct (3) as the cable (2) passes through a nozzle (6) and into the duct. When the velocity of the liquid (4a) through the duct is higher than the current velocity of the cable (2) through said duct, the cable section enclosed in the duct will be subjected to a pulling force that acts along the cable, and the duct-enclosed cable section will be supported by the liquid and/or its weight reduced. A first device (7) which functions as a nozzle (6) is divided into at least two mutually coacting parts (71 or 72) and packing material (73) included in a packing arrangement (70) lies in abutment with the cable (2) and with at least one of said parts (71, 72).
