:) In fact the best fun was ding the 'ball bearing' test down the hoses

- basically blow a nylon ball bearing down a hose in an umbilical to make sure it hasn't collapsed in production. The worst situation happens when you hear the bearing whizzing around an umbilical for it to stop suddenly in the middle third somewhere.

Amusing, until you realise what has to be done to fix it!!!!

On the ends of the cables, R1plus R2 method for copper. Fibre tester for fibre. The bugger is at the donkey's doo-da great - big mess of wires, multipairs and fibres which have to be dressed in a tight space to the respective electronic, electrical, camera, positioning, etc pods.

I'd never seen (from the inside) the umbilicals - the ones they lay on the seabed for subsea equipment until last week. About 300mm diameter and ring of four cores, multicores, tubes and pipes. Quite interesting to see opened up rather than from the cameras of an ROV..
