Valves for FLNG / FPSO
Valves for FLNG / FPSO
(OP)
I am working on FLNG project, i will be very thankful if anybody who has knowledge on FLNG / FPSO projects at EPC or at Valve manufacturer, tell me if any special valves are available in market for space saving.
Conventional Double Block & Bleed arrangement takes lot of space. Is their any valves available for positive isolation to replace this arrangement. Application will be CRYOGENIC (-196 deg.cel.)
Thanks in advance.

Finally a bit more information is always welcome. When you say "save space," how much space are you trying to save? What size opening do you need the valve to fit?

I asked very generalised manner, Its not case specific.
I am thinking of some special valve which can replace 2 GTV, Spool Piece, Drain valve.

If you are looking to replace the traditional DBB piping arrangement, I'd look at the double-ball valve.
RE: Valves for FLNG / FPSO
you may consider triple offset butterfly valves in a DDB arrangement ( ie two discs in one casting ) Zwick Valves of Germany have a lot of shipbuilding and cryogenic supply experience.

for more information about the Valve type mentioned by jeffvalve and a wider choice of Manufacturers, maybe you'll want to take a look at thread408-126483: Discussion on triple offset valve and thread408-135872: The top three sellers for butterfly valve? within this Forum.
Hope this helps, 'NGL

I guess you should check them.
RE: Valves for FLNG / FPSO
So, my advice is to reduce the dimensions of the complete system instead of only the valve; this is if the situation allows you, of course...
