Carey,

I am attaching a short list of the companies who might be able to do a
reasonable model.  All but ABS have designed rigs.  ABS is a
classification
society that has access to much of the engineering detail and MIGHT be
able
to do a model -- but I don't know.

I'm also attaching a copy of the running spreadsheet of rigs that I
maintain.  Where I have been able to identify a "class" for the rig, it
is
indicated; however, this doesn't mean that two rigs in the same class
are
the same -- just that they were originally built to similar plans.  If
you
play around with sorting it, you will find that the vast majority of the
rigs currently in the US are controlled by less than a dozen companies.

With the exception of the rigs built for Petrobras, I wouldn't rule out
any
of the rigs built since 1990 as candidates for US operations, given
appropriate market conditions.

There is an online database at rigzone.com that has some powering
information for the rigs available and may be more-up-to-date than mine
regarding operating locale.  Just seat of the pants, but I'd guess that
anything with more than 3,500 HP installed should be examined to see if
it
exceeds 2   million GPD uptake.
