Re: Butterworthing.
When on Gulf tankers we used Heather Bond they had a whole series of different compounds for filling bronze brass aluminium steel repairing pipes etc but the main thing we use for repairing pipes with like a 6 inch long jubilee clip that you put around the pipe and I think it had two or three tensioning screws that you can send it up on and a rubber liner once i't clamped on the pipe it was therefore good

Today on VLCCs there is a branch line from the main discharge line. that leads into the Butterworth machine. that rotates at a high angle and slowly as the tank level of the crude goes down the angle changes, it blasts all the tank side removing the crude and scales of rust. all th way down to the bottom and all the tank bottom is blasted with the outgoing crude, leaving the tank all nice and clean.
At the same time the Tank is full of inert gas, so no risk of explosion. All the sludge and scales are discharged with the cargo.

It came in early seventies, VLCCS in Shell had fixed machines but also had Butterworth heaters (hot washing stopped after the Mactra blew up 69 / 70). I did a trial discharge in Europort on Marticia in 71/72 ish. The main reasons were that the shoreside decided that as the sludge was oil rich they wanted it as previously they did not, other reasons included, COW (crude oil washing) as it became known as , meant that operations were carried out in over rich conditions so safer, and the best thing to remove oil sludge was - oil.
