Ram BOP, Cameron UII Style, 13-5/8" 15,000 psi WP, Double Cavity, HPHT + Sour Service (NACE MR0175)

The Ram BOP, Cameron UII Style, 13-5/8" 15,000 psi WP, Double Cavity, HPHT + Sour Service (NACE MR0175) is a complete ram bop (double) unit rated for 15,000 psi working pressure (15K class) in hpht + sour. The 13-5/8" 15K HPHT ram BOP is the high-end of the regional ram fleet — required for ultra-sour HPHT plays where 10K WP is insufficient. Sour-service NACE MR0175 trim throughout, HPHT temperature qualification, larger-cylinder operating piston. 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. HPHT-capable trim — qualified for high-pressure / high-temperature service consistent with Hail & Ghasha (ADNOC), Jafurah (Aramco), and equivalent ultra-deep sour gas plays.

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 UII 13-5/8" 15K
• Shaffer NXT-15K 13-5/8"
• Hydril V 13-5/8" 15K

OEM cross-reference: Cameron UII 13-5/8" 15K (genuine), Shaffer NXT-15K 13-5/8", Hydril V 13-5/8" 15K — HPHT-trim equivalents.

Applications

• ADNOC Hail & Ghasha ultra-sour gas drilling (H₂S up to 30%)
• Aramco Jafurah unconventional sour gas
• Oman Khazzan / Ghazeer tight gas
• Saudi Khuff gas at 15K WP
• Iraq deep-gas exploratory drilling

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)
• HPHT trim qualification (high-pressure / high-temperature)
• 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.

Companion products

Pair with matched-pressure 15K BOP control unit (Koomey-style accumulator), API 16C choke & kill manifold, BX ring gaskets, B7M studs and 2H nuts (sour service), HNBR / AFLAS elastomer kits, and matching drilling spool / DSA crossover. Annual redress kits and 5-year API 16A recertification service available — see the BOP Services category.
