Ever watch the film"watch my stern"a lot of shots of Chatham yard and ships,if so,did you remember the reel of wire /Peter cellars bit ,so tru to what went on somtimes.
Now I speak from personal experience,spent a very boring Easter bank holiday on duty,we ended up with a welding gang trying to spear plastic cups in the basins,our spears were welding rods,no idea the cost of a rod ,we must have thrown dozens in. Often coverd welders working on the hull of nukes in side the designated safty zones,unused rods were seldom returned to the stores ,lose them in the basin was the order of the day,if truth is known there was a colossal amount of waste in the nuclear complex that could have been avoidid.
