Here is a Subsea BOP Multiplex Control pod that is used on one of the rigs I am over.

The bell on top is a one atmosphere housing that communicates to the surface via fiber optic umbilical and also receives 480vac from surface. Deployment depth is rated to 10,000ft and there are two mounted on the subsea BOP stack to allow for redundancy if one fails. There is a bank of GE Fanuc PLC's mounted in the bell and they output a 24vdc signal to a solenoid operated pilot valve which shifts a larger hydraulic valve that send hydraulics to the desired actuator on the BOP stack, to close the well bore off for example.

Model in MoI and render in Carrara.

Holy cow that's impressive.

I always think this when I see something complex, but how do you manage all the parts without some kind of grouping function?

Dan

I highly suspect that the orient tool came in handy for this model.

Nice work.

Hi Grendel, that's amazing!

Is this the one that you were talking about back in the PDF thread here:
http://moi3d.com/forum/index.php?webtag=MOI&msg=3482.4 ?

Just 3 days of work for the whole project? Or is this a version that has been continued and had more detail added?

Very cool.

- Michael

Thanks Dan, Steve and Michael. For the grouping I actually started using the style system for quick isolation of sub-assemblies.

This is not the pod mentioned in the pdf thread as that one is still in manufacturing and under confidentiality agreement until my company receives custody of the finished product. This pod uses some of the same components but arranged in a different configuration.

Hi Grendel,

Wow, that's a very impressive looking model, Well done!!

regards Colin

Nice! Hard to dive to 10,000ft and take some product shots in action 8).
Rainer

Very cool Grendel. Your render is excellent. Did you composite the images or was that set up in Carrara?

Thanks all, the straight render was a base layer then I comp'd a toon line layer over the render to make the edges of the components more defined.

Thanks for the info, it turned out very well!

Very Technical !

Wow, I missed this one, I love this kind of technical work ... it's so sexy :)
Well done Grendel.

... (some parts will definitivelly inspire me for some sci-fi works :))

I've always wanted to know what a Flux Capacitor looked like! :-D

Excellent work, Grendel!

-Will

I also missed this one first time around. Awesome work!

I gather this unit is something like the one they are trying to get working to shut off the well from that oil rig which caught fire and sank?

Mark

Thanks Will, Paq and Mark.

This is the control pod which would convert the command signal from the rig via fiber optic umbilical to hydraulic force which should have closed the blind shear rams and isolated the wellbore. You have a 18-3/4" wellbore with two pistons opposing each other perpendicular to the wellbore. These two pistons move a set of ram blocks with seal assemblies over the wellbore and isolate the wellbore from anything else. Blind Shear rams are designed to seal off against open hole (no tubulars..drill pipe etc) or to cut the tubular in half and then seal against the now open hole. It's a force calculation if there is enough piston area in relation to the wall thickness and tensile value of the tubular, blind shears will not cut everything....that is why in operations you do not place certain tubulars across the BOP stack.

I am a subsea engineer from another company similar to the one that owned the Deepwater Horizon. There was either a deficiency in the control circuit (something did not operate as designed) or they could not cut the tubular they had across the BOP's.
