Kao Collins’ umbilical replacement process begins with a continuity check and visual inspection of all the cables. If any cable fails the test or has any visual nick or damage, it is replaced. All tubing and tube fittings are replaced, as well as the fiber optic cable. Everything is then pulled through a new flexible conduit and new electrical connectors are installed at both ends. A final continuity check is done to insure that the new cables/connectors/pins have been installed properly.
