I was reading an article in the press this week about a project to lay an undersea cable across the Tasman Sea. The ship had had to return to port for repairs and return to complete the job later.
This got me wondering: how does the ship secure the end of the laid cable, and how does it retrieve the cable to continue the cable-laying operation?
In this instance it was a fibre-optic cable for telecoms use - would there be differences for other cable types?
Similarly, I imagine that very long cable runs (e.g. trans-Pacific) would need to be laid in more than one piece. Would similar techniques be used, or would some different approach be used for planned breaks?
