Failure in underwater cable connectors

What is it about?

The connectors that join underwater/deep-sea cables eventually fail. This is mainly through a process known as cathodic delamination. This is where the metal in the connectors acts as an electrode and an alkaline environment is created. The coating (polyurethane) to metal bond is then attacked by this alkaline environment and the coating pulls off (delaminates). This paper investigates such failures and offers solutions to limit their occurrence.

Why is it important?

Failure of underwater/deep-sea cables is costly and inconvenient. Methods of preventing these and increasing the lifetime of the cable connectors are much desired.
