  • Patent number: 11355263
    Abstract: The invention relates to insulated submarine cables including conductive cores (3a, 3b) and insulating material (5a, 5b) surrounding the conductive cores (3a, 3b). Such an insulated cable includes a first length and a second length. The cable has a roughly constant core (3a) cross-sectional area A1 and a roughly constant insulating material (5a) thickness T1 along the first length, and a different roughly constant core (3b) cross-sectional area A3 and/or a different roughly constant insulating material (5b) thickness T2 along the second length. The cable may include one or more other lengths which join the first length and the second length to one another.

  • Patent number: 11346390
    Abstract: The invention relates to an umbilical termination assembly for terminating a cable or umbilical. The termination assembly comprises a plurality of umbilical elements extending from an umbilical and which pass through a bulkhead plate. The seated ball element has a spherical body through which an umbilical element passes. The ball element is seated in a cup member which allows the ball element to rotate through a large range of angles allowing it to be aligned with the umbilical element without the umbilical element needing to be manipulated or forced into position. The umbilical element can then be attached to the ball element which is supported by the cup member on the bulkhead. This allows the axial tension in the umbilical element to be transferred to the bulkhead.

  • Patent number: 11043770
    Abstract: A cable breakaway device for use with a power cable connector and a power cable, the power cable connector comprising a sheath and a bearing surface. The cable breakaway device comprising a body with an elongate channel passing therethrough, one or more sharp protrusions radially extending from the body to cut the sheath as the cable is pulled through the channel, allowing the bearing surface to engage the breakaway device without impeding the movement of the connecting device.

  • Patent number: 10422059
    Abstract: The present invention provides a means for shutting down a braiding machine to prevent damage to a product to which the braided yarn is applied under failure conditions such as when a yarn breaks. Failure of the yarn or the tensioning of the yarn causes an imbalance in the tensioning on the product causing it to be displaced from its normal position and this displacement is detected to shut the braiding machine down.

  • Patent number: 10167062
    Abstract: The invention provides a floatable cable loading facility (3) for receiving and controlling a cable storage tank (1) which can be used without providing additional infrastructure on a quay or vessel. The cable loading facility is able to receive and retain a tank (1) while rotating it to allow loading and unloading of the cable.

  • Patent number: 8567015
    Abstract: A cable termination system and method of assembly is provided that clamps strength members of the cable after they have been wrapped around a winding member. The clamping force required is therefore reduced by the capstan effect of the winding member. The winding member is preferably a torus that encircles the cable, and the system may comprise a number of progressively larger tori arranged in sequence along the cable to provide sufficient room for wrapping all of the strength members around them.

  • Patent number: 8541683
    Abstract: An armoured cable termination system and method of assembly is provided that clamps the armour wires of the cable over and around the back of a conical inner armour clamp member. The wires are also retained between the inner clamp member and an outer body and a securing end plate. The armour wires are splayed by the inner clamp member, which is forced onto the cable to displace the armour wires. The forcing mechanism is used to support an armour wire former that bends the armour wires around the back of the inner clamp member. The top clamp is then forced onto the termination assembly, such that the armour wires adopt a smooth curve around the back of the inner clamp and are securely clamped along their length. The assembly may then be mounted to a flexible pulling head for pulling it into contact with a structure.
