During the inspection of a hoistable suspended deck on a RoRo ship it was discovered that the wire rope ends had started to slip out of the closed spelter sockets. The sockets were of the moulded epoxy type, and the reason for the cable starting to slip could have been that the moulding was carried out when the epoxy compound had the wrong temperature, or that during manufacture the wire was not sufficiently cleaned.
When moulding the socket it is also important to ensure that all the wire threads and cores are completely enclosed by the spelter socket and that no threads are exposed, since water could then penetrate the moulding. It is crucial for good results that instructions for moulding are followed meticulously, including specifications for temperature during the process.
