摘要:
It is characterized in that it consists in using a self-propelled sea plough (1) remote-controlled via a control flexible (2), said sea plough carrying at least one reel (6) of flexible conduit (7), controlling said sea plough from a site (5) so as to lay and bury a length of the flexible conduit up to a first predetermined point (P.sub.1), controlling said sea plough beyond said first predetermined point from another site (10), continuing laying and burying of the flexible conduit as far as a second predetermined point (P.sub.2), one of said sites being the land (5) and the other comprising a waterborne vessel. Applications include simultaneous laying and burying of flexible conduits such as optical cables, coaxial cables for analogue transmission, electrical cables, single or multiple flexible tubular conduits.

A system for connecting an oil pipeline to an underwater system of piles consists of a baseplate anchored to the seabed with the aid of a drilling ship. The baseplate is provided with a pulley and a locking element. By means of a cable, an end of a frame bearing the first section of pipe to be connected to a conduit is displaced until it locks in the element. The frame also bears a guide structure. A tool bearing connectors coupled by a conduit is then lowered and introduced into the guide structures successively to obtain the desired connection.

In laying an electric cable underwater, the finishing end of the cable is brought ashore by laying the cable end portion (from the cable laying ship) along a course parallel to the shore and as close to the shore as the ship can reach, then pulling the cable end to shore using a rope, pulling the cable end along the shore to the intended landing point, and then pulling the cable end in-land along the intended laying line until the whole cable is positioned along this line. Buoyancy devices are attached at intervals to the cable end portion for the duration of the landing process, to facilitate the sliding movement of the cable over the bottom.
