In the early seventies the boffins at Cayzer House decided that chipping and painting would be replaced by shot blasting.
This caused unforeseen problems:-
1: Continual usage for 12 huours a day increased maintenance on the ships air comprEssors.
2: The main engine vent fans were located above the bridge.
The first time the deck crew tried the shotblasting it was aresounding success, the steel plate was nice and shiny. Unfortunately the forgot to prime the steel plate, result next morning a thin coat of roast had appeared overnight, so the whole thing had to be repeated.
The main engine vent fans sucked in the crap, result ER was coated in dust. The dust and crap damaged the bearings on one of the main fridge comprEssors.
Next trip the boffins decided, despite all the problems that the experiment was an overwhelming success.
In order to alleviate main compressor problems the company bought a portable compressor which was lashed to the deck.
Deck rust removal productivity improved, ER cleaning took a nose dive.
