Umbilical Winch - Tested to Destruction

{tag_name_nolink}

In May, 2015 Shaw Lifting’s client were required to test the integrity and breaking strength of their Umbilical Wires. The Umbilical Wire is used to operate the remotely operated vehicles and equipment on the seabed from control units on vessels and used in conjunction with the launch and recovery systems of the vessel.

The Umbilical Wire is made up of various strands, including a wire outer strand (armour) and various electric cabling and fibre optics internally.

Shaw Lifting were given a number of samples of the wire in approximately 2.0 Metre lengths to be tested to destruction to ensure the wire breaks at the manufacturer’s nominal breaking load. As the wire had to fit into a hydraulic test bed for test, Shaw Lifting fitted a closed spelter socket each end by Wirelock ® Resin. This meant each wire had to be carefully untwined from the cable and spread out within the centre of the socket, where the Wirelok resin was poured in and left to set.

Once this was done, the wire was sent off to an independent test facility and tested to destruction on a calibrated 200.00 Tonne capacity test machine, where the breaking load was taken upon test.

Shaw Lifting are registered under ISO 9001 to carry out socketing by Wirelock ® as part of their remit meaning that the correct socketing and testing of the wire, resulted in that the wire broke as it should and reached a breaking load of 1.4% above the manufacturers original given value.
