A device for installing a cable in a practiced at the bottom of the sea.

摘要

The present invention relates to a device for putting in place at a voltage of t1, a cable 12 in a trench practiced in the seabed and to handle the cable during its production, which cable 12 initially rests by its own weight on the bottom and is subjected to a voltage t2, the so-called "laying tension", which voltage t2 is which is greater at the voltage of t1, the voltage of the handling of the cable 12 which are not to exceed a maximum voltage of safe predetermined t3. / p & & p & this device is characterizes by the fact that it comprises: / p & & p & a.des means 1617 developping a constant force in order to grip the cable 12 at a point taken along its length and to the elevate has a height which gives the value of a voltage of t4 so that t2t4t3, this lifting action, causing an elongation of at least a portion of the cable, and to rest on the seabed, said portion of cable having undergone this elongation, the relaxation of the cable to the ground, thereby bringing the voltage of the cable has a value t1 burying; / p & & p & b.et means 34 for deposit to the voltage t1 the cable 12 relaxed at the bottom of the trench. / p & & p & finds its application in the context of the work under -.
