U BOP Hydraulic Control SystemThe U blowout preventer is designed so that hydraulic pressure opens and closes the rams and provides themeans for quick ram change-out.Ram closing pressure closes the rams. When the bonnet bolts are removed, closing pressure opens the bonnet.After the bonnet has moved to the fully extended position, the ram is clear of the body. An eyebolt can be installedin the top of each ram to lift it out of the preventer.Ram opening pressure opens the rams. Following ram change-out, this pressure closes the bonnets. The rams arepulled outward, near the bonnets, before the bonnets begin moving toward the preventer body. This assuresthat the rams never obstruct the bore or interfere with the pipe in the hole. Hydraulic pressure draws the bonnetstightly against the preventer body and the bonnet bolts are reinstalled to hold the bonnets closed.U BOP Operating Data and Fluid RequirementsLarge Bore Shear Bonnet Operating Data and Fluid RequirementsBore Size andWorkingPressureGals toOpenPipe Rams(1 Set)Gals toClosePipeRams(1 Set)LockingScrewTurns(Each End)ClosingRatioOpeningRatioBore Size andWorkingPressureGals to OpenPipe Rams(1 Set)Gals toClosePipe Rams(1 Set)LockingScrew Turns(Each End)7-1/16” All WP 1.3 1.3 18 6.9:1 2.2:1 7-1/16” All WP - - - - -11” Except 15,000 psi 3.4 3.5 27 7.3:1 2.5:111” Except 15,000psiClosingRatioOpeningRatio6.8 6.0 27 12.0:1 4.8:111” 15,000 psi 5.7 5.8 32 9.8:1 2.2:1 11” 15,000 psi 8.9 9.0 32 15.2:1 3.7:113-5/8” Except15,000 psi13-5/8” 15,000 psiModel B16-3/4” 3000 psiModel B16-3/4” 5000 psiModel B5.5 5.8 32 7.0:1 2.3:110.4 10.6 45 10.6:1 3.6:19.8 10.6 38 6.8:1 2.3:19.8 10.6 38 6.8:1 2.3:113-5/8” Except15,000 psi13-5/8” 15,000 psiModel B16-3/4” 3000 psiModel B16-3/4” 5000 psiModel B10.5 10.9 32 10.8:1 4.5:116.0 16.2 45 16.2:1 6.0:118.2 19.0 38 10.4:1 4.4:118.2 19.0 38 10.4:1 4.4:116-3/4” 10,000 psi 11.6 12.5 45 6.8:1 2.3:1 16-3/4” 10,000 psi 18.2 19.1 45 10.4:1 4.4:118-3/4” 10,000 psi 21.3 23.1 54 7.4:1 3.7:1 18-3/4” 10,000 psi - - - - -20-3/4” 3000 psi 8.1 8.7 46 7.0:1 1.3:1 20-3/4” 3000 ps 14.3 14.9 46 10.8:1 1.7:121-1/4” 2000 psi 9.0 8.7 46 7.0:1 1.3:1 21-1/4” 2000 psi 14.3 14.9 46 10.8:1 1.7:121-1/4” 5000 psi 27.3 30.0 54 7.2:1 4.0:1 21-1/4” 5000 psi - - - - -21-1/4” 10,000 psi 24.5 26.9 51 7.2:1 4.0:1 21-1/4” 10,000 psi - - - - -26-3/4” 3000 psi 10.1 10.8 58 7.0:1 1.0:1 26-3/4” 3000 ps - - - - -TC1001 12 © 2002 Cooper Cameron, Cameron Division
