During an availability, the repair crews (millwrights and machinists, pipers and riggers and welders, foremen, etc are all scheduled on two 7x12 hour shifts (or 2x6x12 hour shifts if Sundays are off), then (usually) a startup crew comes on right towards the end with dedicated startup and testing crews that are (almost always) even smaller.
Even with shift turnovers taking 1/2 hour before and after each shift, it’s generally just the floor engineers and general foreman who stay over. You can’t delay testing (steam and boiler heatup, vibration checks, oil flow checks and heatup, oil flushes, or whatever) just because it’s a Sunday.
It was John W questioning the startup...not I. :-)
This is new construction. I read they we’re going commercial in June. We had start up on site before back feed. Maybe two months before. I wonder if they had started steam blows yet. Or was this initial CT light off? Chances are, there were a lot of construction guys on site working on Punch List items etc.
