Abstract
An apparatus for installation and protection of subsea cables comprises at least a first tubular member (1) and at least a second tubular member (2). Both these are arranged to be installed subsea with a subsea foundation (3). This allows passage of cable (29) through it. The first tubular member (1) is arranged telescopically within the second tubular member (2) so as to extract outwardly towards seabed (5) from an end portion (7), with respect to the second tubular member (2), only up to a prefixed length. This ensures that a continuous conduit for the cable is obtained through the scour protection of the foundation (3). The present invention also includes a methodology for installation of the apparatus and a method for installing a cable through the scour protection of the foundation, by using the apparatus.
