There is provided a method of manufacturing a power cable, the power cable comprising at least a cable core and a lead-free metallic water barrier (202) surrounding the cable core. The method comprises heating at least a first portion of the lead-free metallic water barrier (202); surrounding the first portion of the lead-free metallic water barrier (202) with a heat-activatable adhesive layer (212); and surrounding at least a portion of the adhesive layer (212) with a reinforcement layer (216). The adhesive layer (212) adheres to the water barrier (202) and to the reinforcement layer (216).

There is provided a cable handling system for deploying a cable bundle from a cable-laying vessel. The cable bundle comprises a first layer and a second layer on top of the first layer. The first layer comprises a first cable and a second cable adjacent to the first cable. The second layer comprises a third cable. The cable handling system comprises an over-boarding guide assembly comprising a curved surface for bending the cable bundle as the cable bundle is deployed overboard. The cable handling system comprises a bundle support structure provided on or adjacent to the over-boarding guide assembly. The cable handling system comprises a first side support and a second side support arranged such that the first layer of the cable bundle is receivable therebetween as the cable bundle is bent. The first and second side supports are arranged to substantially constrain lateral movement of the first cable with respect to the second cable as the cable bundle passes therethrough.
