A method for manufacturing a closed-loop cable (1), said cable comprising a core (2) and metal strands (3) wound in a helix about the core (2), wherein the two ends of the cable are connected in splice areas in which splice knots are formed using the ends of each of the strands (3), which are then inserted into the cable after having locally removed the core (2) therefrom, each splice area then being overmoulded with a polymer. The invention also concerns a method for manufacturing a closed-loop cable (1) wherein the ends of the strands (2) are lined by overmoulding them with a polymer, prior to inserting same into the cable (1). It finally concerns a corresponding closed-loop cable (1) and the use thereof as a pure traction cable or as a hauling traction cable.
Hauling rope (1) comprising a one-piece core (2) comprising a central core strand (4) provided on its periphery with a series of evenly spaced fins (5) between them forming receiving grooves (6) of at least partially circular cross section and strands (3) arranged around the core (2) by insertion in each of the receiving grooves (6) such that the combination of the core and of the strands (3) has an external envelope of substantially cylindrical shape, the diameter of the receiving grooves (6) being smaller than or equal to that of the strands (3). The use of this rope (1) as a pure hauling rope or as a carrying-hauling rope is also disclosed.
A profiled wire, of NACE grade, made of low-alloy carbon steel intended to be used in the offshore oil exploitation sector is provided. The profiled wire includes the following chemical composition, expressed in percentages by weight of the total mass: 0.75<% C<0.95; 0.30<% Mn<0.85; Cr≦0.4%; V≦0.16%; Si≦1.40% and preferably ≧0.15%; and optionally no more than 0.06% Al, no more than 0.1% Ni and no more than 0.1% Cu, the balance being iron and the inevitable impurities arising from smelting the metal in the liquid state. The steel is obtained, from hot-rolled rod stock cooled down to room temperature, and then having a diameter of about 5 to 30 mm, by subjecting this starting rod firstly to a thermomechanical treatment comprising two successive steps carried out in order, namely an isothermal quench, giving it a homogeneous perlitic microstructure, followed by a mechanical transformation operation carried out cold with an overall degree of work-hardening (or reduction ratio) of between 50 and 80% at most, so as to give the wire its definitive shape, and in that the profiled wire thus obtained is then subjected to a restoration heat treatment of short duration carried out below Ac1 (preferably between 410 and 710° C.), giving it the desired final mechanical properties.

Intended primarily to be mounted at the end of a mooring cable of a system for anchoring a mobile solid element, this socket comprises a socket body 12 that has an internal cavity 14 comprising a guide chamber 34 for guiding the mooring cable 22, an intermediate section 18 and a socketing space 20 intended to accept and immobilize the ends of the strands of the mooring cable 22, and coupling members 30, 30' for coupling to the mobile solid element that is to be anchored, these members being positioned on the socket body 12 so as to define an axis of pivoting 32 of the socket body 12 that passes through the intermediate section 18. Use of the socket in anchoring systems, notably in an offshore environment, ensures natural self alignment of the socket with the cable to which it is fitted during the various movements to which the anchoring system is subjected.
