Kent:

Here
are
two
quick
questions
related
to
offshore
oil
and
gas
operations
that
I
hope
you
can
help
answer.
Please
let
me
know
if
you'll
be
able
to
answer
these
questions
and
the
ETA.
Thanks!

Q1.
Is
it
typical
for
an
offshore
oil
and
gas
extraction
fixed
facility
(
e.
g.,
TLP,
Spar)
to
shut­
in
periodically
for
production
maintenance?

Q2.
If
yes,
at
what
frequency
would
this
occur
and
for
how
long
(
X
times
a
year
and
on
average
Y
days
of
downtime)?
