DiveCentre,
"Friday 11.14am Boyzee asked a question which has received no answer:
What exactly hapoens once the AM arrives ... i know we hook up ...but before that ...after it?
Before hook up I assume there is very little to do but wait for a weather window, But after there will presumably be various things that have to be done before we have (that magic word) FOIL. It is something I had thought about asking. Any technical experts willing to say what those various things, procedures etc are, how long it will take, potential problems etc etc."
Hmm, yes, Boyzee's questions appeared to get lost in other more pressing stuff about politics and so on.
OK. This is waay out of my 'expertise', but I don't mind hazarding a few guesses.
Once hookup (latching to the buoy) is achived, I think the first 'tests' will be related to the 'marine' side of things. Ensuring good turret rotation, establishing various loads, behaviour-patterns, etc.
Then there will have to be full pressure-testing of all connections between the flowlines from the wells already connected to the buoy and between the (now-connected) buoy and the boat itself.
This will take time. How long, I don't know, and it's outside my expertise.
I'm assuming (with all that risks) that the production train has already been pressure-tested).
So then a slow, cautious opening of a well to 'prime' the entire nine yards and enter 'production'. Though I suspect even that phase, won't be counted as 'FoiL', though nearby witnesses might see the flare.
How long will it take? Personally, haven't a clue.
Potential problems? Finding something so simple as a leaking connection somewhere, requiring purging of whatever part of the system it's attached to, doing the repair, and re-starting. Stuff which 'timescale contingency' allows for.
Once EPS is working, and FoiL is RNS'd, there'll already have been oil and gas going through the system. But checking it's all working right.
How long is a piece of string?
The company will have a detailed 'timeline breakdown lookahead' for all this stuff. But I doubt anyone on a PI's BB like this has access to it, and if they have, they probably shouldn't be posting here, anyway!
