Abstract

Method and apparatus for installing cables in tubes, in which the cable is installed by the combination of a pushing force and the drag force of a fluid under pressure which is passed through the tube, wherein, during the installation, as fluid, a first medium with first hydrodynamic properties is passed into the tube and at certain moments a second medium with second hydrodynamic properties. It has been found, surprisingly, that by the use of media having different hydrodynamic properties, such as, for instance, a gas and a liquid, the installation length of the cable can be increased.
