What MJB International does

MJB International (trading as MJB and Masaood John Brown) is a Dubai-headquartered, independent total service provider for industrial gas turbines, founded in 1979 as a joint venture between the Masaood family and John Brown Engineering and re-incorporated in 2000 after GE's acquisition of Kvaerner Energy. The company specializes in GE Frame turbines (Frame 3, 5, 6, 7 and 9) and offers an integrated portfolio covering spare parts, component repair, rotor overhaul and life assessment, refurbished turbine packages, field engineering, control panel manufacture (including the proprietary Sentinel C TMR retrofit), condition monitoring, modifications and upgrades, training, and Long Term Service Agreements. Its competitive positioning rests on the OEM heritage of its workforce (over 2,000 man-years of John Brown Engineering experience) and a capital-intensive Jebel Ali Free Zone facility of approximately 8,270 sq m of workshops plus 10,000 sq m of storage, equipped with a 150-ton overhead crane, plasma spray thermal barrier coating lines, vacuum furnaces, multiple-rotor balancing equipment and the Paragon rotor stacking system.

The company serves power generation operators, upstream and midstream oil and gas operators, and industrial users of heavy-duty gas turbines, with named customers including Abu Dhabi Gas Liquefaction Company (ADGAS), GASCO, ZADCO, Harouge Oil Operations, AES Kelanitissa, Office National de l'Électricité (Morocco), Iraq's Ministry of Electricity, and regional channel partner AJ Stack Solutions in Australia. Commercial reach spans the UAE, Saudi Arabia, Kuwait, Qatar, Oman, Bahrain, Iraq, Libya, the United Kingdom, Morocco, Nigeria, Sri Lanka, Malaysia, Kazakhstan, Pakistan, India and Australia.

MJB generates revenue through project-based professional services (overhauls, rehabilitations, field engineering, training), one-time parts and refurbished turbine package sales, and recurring Long Term Service Agreements, with pricing quoted project-by-project and not publicly disclosed. Marketing relies on direct enterprise field sales supported by participation in major exhibitions including ADIPEC, ME RoTIC, MaintCon, AOG and POWER-GEN Asia, complemented by an active LinkedIn and YouTube presence and downloadable brochures. The operating entity is MJB International Limited LLC, registered in the United Arab Emirates, with a sales office in Abu Dhabi and an engineering and logistics arm (PCSI Ltd) in Glasgow, UK.

Four partnerships are on record, tiered core and minor.

• ValmetcoreStrategic or Co-development PartnerIn February 2017, MJB International signed a cooperation agreement with Valmet, a leading global developer and supplier of process technologies, automation and services for the pulp, paper and energy industries. Under the agreement, MJB and Valmet jointly developed triple modular redundant (TMR) gas turbine control systems as part of MJBI's gas turbine retrofit capabilities. MJB International uses Valmet's gas turbine automation controllers with its own Sentinel C control systems to replace obsolete GE triple modular redundant control systems. Valmet's automation system is included in MJB's complete gas turbine retrofit projects, accelerating Valmet's market growth in automation for gas turbine retrofit projects.
• AJ Stack SolutionscoreChannel Partner/ Reseller/ DistributorMJB announced the extension of its heavy frame gas turbine services partnership with AJ Stack Solutions in Australia in February 2025. AJ Stack Solutions serves as a regional channel partner distributing MJB's heavy frame gas turbine services in the Australian market, extending MJB's geographic reach in the Asia-Pacific region.

Direct peers

• Mechanical Dynamics & Analysis (MDA): Independent industrial gas turbine services firm specializing in vibration analysis, rotor repair, dynamic balancing, and condition monitoring. Highly comparable in technical depth and overlap with MJB's rotor overhaul and condition monitoring service lines.
• Sulzer (Turbo Services): Independent industrial turbomachinery service provider offering rotor repair, component refurbishment, and field services. Directly comparable to MJB's component repair, rotor overhaul, and gas turbine service capabilities across the same target customers.
• EthosEnergy: Independent industrial gas turbine service provider offering parts, repair, overhaul, and field services for GE, Siemens, and other heavy-duty frames. Directly comparable to MJB as an OEM-independent aftermarket specialist competing for the same customer wallet share.
• ProEnergy Services: Independent provider of gas turbine packaging, maintenance, and field services for GE Frame and aeroderivative units. Direct competitor in the heavy-duty GE Frame aftermarket, with comparable offerings around refurbishment, parts, and on-site services.
• Turbine Services Ltd (TSL): UK-based independent industrial gas turbine service provider offering parts, repair, and overhaul for GE and other frames. Direct peer with similar focus on the legacy GE Frame aftermarket and comparable geographic exposure.

Broad incumbents

• Solar Turbines (Caterpillar): OEM and service provider for industrial gas turbines, primarily Mars and Centaur frames, with comprehensive aftermarket support. Comparable in the gas turbine O&M space, particularly for non-GE platforms and as an OEM service alternative to independent providers.
• Siemens Energy (Industrial Applications Service): OEM and service provider offering comprehensive gas turbine O&M, including control retrofits and life extension. Competitively relevant where MJB encounters non-GE frames (Siemens SGT series) and as a benchmark for OEM service offerings competing with independent providers.
• Wood Group (Gas Turbine Services): Global energy services major with industrial gas turbine maintenance, repair, and overhaul offerings. Broader portfolio spanning upstream, midstream, and renewables, but with a directly comparable gas turbine aftermarket practice competing for similar enterprise customers.
• MAN Energy Solutions (MAN Turbo): OEM and service provider for large industrial gas turbines and turbomachinery. Comparable in the heavy-duty gas turbine service domain, particularly in the Middle East where it competes for overhaul and O&M contracts, though it also sells new equipment.

Emerging players

• Valmet Automation (Gas Turbine Control): Process automation provider that partnered with MJB on the Sentinel C TMR control system. Comparable in the gas turbine control retrofit niche—relevant as both a collaboration partner and an emerging competitor in the turbine automation layer.
