  • Local remote operated vehicle for installing elongate element on seabed
    Patent number: 6113312
    Abstract: A local remote operated vehicle for installing an elongated element (1)--such as a submarine cable--on a sea bed from a laying vessel or cable ship (2),--includes a guideweight/tracking gear (4) suspended from the ship and riding on the element (1). The gear (4) includes a garage (10) for hosting a local ROV (11) linked to the garage with a tether cable (12) long enough to enable the towed local ROV to monitor the element touchdown area (6).

  • Bending restrictor
    Patent number: 5909007
    Abstract: A device for restricting the bending diameter and bending strain exerted on elongated articles (1) such as cables, pipes, umbilicals and other elongated articles is used when installating such articles from a cable ship to a sea bed. There is used a number of wire elements (32,33) which are arranged for tensioning the annular elements into contact with each other. The wire elements (32,33) are equally distributed in or on the annular elements to ensure uniform compression of these elements.

  • Subsea cable installation
    Patent number: 5890841
    Abstract: The present invention relates to a method and means for transferring a construction--consisting of an elongated article (2,21) provided with at least one termination (3,20,40)--between a vertical position and a horizontal position and vice versa. Handling means (10,22,31,44) are attached to the termination housing (3,20,40) so as to balance and handle the termination substantially at a combined center of gravity (14,26,34,45) and thereby prevent undue bending of the elongated article (2,21) during the transfer.
