Ram BOP, Cameron U Style, 11" 5,000 psi WP, Double Cavity, Sour Service (NACE MR0175)

The Ram BOP, Cameron U Style, 11" 5,000 psi WP, Double Cavity, Sour Service (NACE MR0175) is a complete ram bop (double) unit rated for 5,000 psi working pressure (5K class) in sour service (nace mr0175). The 11" 5K Cameron-U-style double ram is the lower-pressure workover ram for shallow / mature wells. Lower-cost lighter-duty option to the 10K — but still sour-service trim by default for the GCC. NACE MR0175 / ISO 15156 sour-service compliant — full body, trim, and bolting hardness controlled per the standard. Required across Saudi Aramco, ADNOC, KOC, PDO, and QatarEnergy default specifications for sour fields.

Construction

• Equipment type: Ram BOP (Double)

• Closing time: < 30 s on largest cavity (per API STD 53)
• Approximate weight: 5,400 kg (transport-ready)

OEM compatibility

Engineered as a recognised matched-pressure interchange / supply for the following OEM equipment lines (Indus Hydraulics is not an authorised distributor of these OEMs — units are sourced through Indus and supplied with full traceability):

• Cameron U 11" 5K
• Shaffer SL 11" 5K
• Hydril V 11" 5K

OEM cross-reference: Cameron U 11" 5K (genuine), Shaffer SL 11" 5K, Hydril V 11" 5K — interchangeable on shallow / mature workover stacks.

Applications

• Workover ram BOP on shallow / mature 11" 5K wellheads
• Bahrain / Iraq south / Oman heavy-oil workovers
• KOC mature-field intervention
• Shallow infill drilling at 5K WP

Performance & testing

Hydrostatic shell test at 1.5× rated working pressure on every unit. Function-test on rams, packers, and seal elements per API STD 53. Mill test reports per EN 10204 3.1 / 3.2 supplied. Charpy V-notch impact testing at low temperature available where service requires toughness verification. Closing-time and seal-pressure data sheets included with FAT package.

Compliance

• API 16A (per equipment class)
• NACE MR0175 / ISO 15156 (sour-service / H₂S)
• EN 10204 3.1 / 3.2 mill test reports
• Hydrostatic test certificates per unit
• Heat-number traceability stamped on body
• FAT (factory acceptance test) report on request

How to order

Confirm on your RFQ: (a) exact bore size, (b) working pressure and pressure class, (c) ram configuration / cavity count (where applicable), (d) end connection family (API 6A studded, flanged, or bolted), (e) service class — sour (NACE MR0175), HPHT, or standard, (f) elastomer compound preference (HNBR / AFLAS for GCC sour service), (g) FAT witness requirement, and (h) destination port for door-to-door logistics. Indus quotes ex-Dubai (AED) with Aramco / ADNOC / KOC vendor-registered logistics support.

Region notes

Stocked / sourced for the GCC: Saudi Arabia (Aramco IKTVA), UAE (ADNOC ICV), Kuwait (KOC), Oman (PDO), Qatar (QatarEnergy), Bahrain (BAPCO), and Iraq south. Sour-service trim is the regional default; Indus carries sour-service variants in stock and treats sweet-service as a build-to-order downgrade.
