CP it's not 'for sure' re payment of deposit, of course it isn't.
It depends on the companies credit ratings and the rig companies own assessments of likelihood to default.
The companies I've worked for only had to pay down payment of mob costs to cover the variables in advance, (and then not always) then paid the balance on 'delivery' (normal credit terms) then paid the ops costs on same arrangements ie one month credit at end of month when invoice presented.
Often as well, if the invoices haven't been effectively pre approved by company man and are erroneous, depending upon specific negotiations in contract this could start the clock ticking for the whole amount of invoice or at the very least, disputed amount.
