SEOUENCE FOR RECEIVINC CERTIFIED DI}IE}ISIONAL OUILINE
1.
Process engineer 6ends punp calculation sheet to the pump mechanical engineer- This shouLd be done shortly after process flov diagrarns are
completed. This calculation sheet contains the operating conditions for one particular 6ervj.ce. the process engi.neer may aLso request punp tlpe if he has a preference.
2.
llechalical engineer uormalLy determines pump tipe ba6ed on calculation sheet information- He fiUs in the I'Pump specification Sheet-rr He will only fill in information noted as "to be corpleted by purchaser."
3.
ltechanical engineer then selects possible vendorE based on avaifable catalog information.
4.
l.techanical engineer fills i.u "pump 1i6t" (6ee attached sheet)- this gives Piping very prelj.minary information thich can be used for plot development or possi-ble p!..ulP 6tudy work- the puilp list refers to an l,l-E-D- drawing nunber- This drawing (see attached 6heet) provides a
visual picture of
proposed pump,
5. llechanical engineering
then goes ortt "Reque6t for Quote" to several Each vendor fj.11s in their portj"on of the Punp specification sheet. They give Fluor a price, pump modeL, and size r,rhich they offer for that particular service. The vendors send the specification sheets and quote sheets to Fluor for consideration-
vendors-
6.
tlechanj.cal engineer $il1 seoal revised information to Piping if vendor's recomme[dation significantly inpacts us- ltore accurate infonnation from veardor I s catalog is noll available -
7. llechanical engineering
places order to the selected venalor. six to eight lreeks later Fluor recej.ves a C-D.o.
8.
Approximately
c-D-o. is "in-house," our Vendor Data Control croup eilI send ?iping di6ciplines a reference copy- c-D.O- is then routed for 6quad check- Piping wonrt normally be included on the routing of the squad check- However, ee {ifl squad check our reference copy and any questions or problems ve have can be dj.scussed with the mechanical engineer- He lhen can include our corunenta !,/ith his when he formal"ly squad checks the c.D.o. Piping and other disciplines wiLl then receive a copy of 'Isquad
t,Ihen
and other
check conulents" which
is
traEsmitted back to vendor.
