Owing to the fact that the previous incumbents backed into an iceberg, the port rudder was twisted 15 degrees on the rudder stock when we got it into dry-dock. So, we had to grind the stock, and put in a stepped bush to get a tight taper that would take 600 bar, to jack the rudder on and off. The blue dye is to show the contact between the bush and the stock, so they've a bit more work to do - you need 85% contact. Peter, our Chief Engineer checks the fit.
