Video transcript During my days at secondary school my best friend's father worked on the docks at Hartlepool. Often, after school, David and I toured the docks on our bicycles.
When David's father was on duty we would call in his control cabin for a cup of tea and view the impressive passing ships.

The Chief Engineer would split the watches into two, normally working six hours on and six hours off.
The electricians changed onto these rotas and worked alongside the engineers. We didn't get much sleep in the six hour break period.
