From isolation to control valves, Terrawatt keeps your flow systems running safely and efficiently with advanced valve servicing solutions—onshore and offshore.
Leveraging state-of-the-art machining, lapping, and surface treatment technologies, we restore valve integrity to original specifications. Our processes include seat resealing, stem polishing, and gland packing replacements, followed by rigorous hydrostatic, pneumatic, and fugitive emission testing. Compliant with API 598 and ASME B16.34, we guarantee leak-tight performance under extreme temperatures and pressures, ensuring valves meet operational demands in refineries, pipelines, and offshore platforms.
When unplanned failures threaten operations, our 24/7 emergency response team deploys rapidly to address leaks, stuck valves, or control system malfunctions. Equipped with mobile testing units and OEM-compatible parts, we perform on-site machining, hot tapping, or full valve replacements—even in hazardous or hard-to-reach environments. Our priority is restoring safe operations within hours, not days, minimising production losses.
Recognising that valve performance requirements vary by application, we design tailored programs for cryogenic LNG systems, high-PT steam lines, or corrosive subsea environments. Services include lubrication regimes, partial-stroke testing for emergency shutdown (ESD) valves, and SIL-rated safety valve recertification. We align maintenance frequency with operational criticality, ensuring compliance while avoiding over-servicing.
Beyond repairs, we empower your team with valve maintenance training programs covering troubleshooting, actuator calibration, and isolation procedures. Coupled with biannual performance audits and compliance reviews, we ensure your valves meet evolving regulatory and operational standards. Partner with us to transform valve maintenance from a cost centre into a strategic asset for reliability, safety, and efficiency.
Our proactive lifecycle management approach combines real-time performance monitoring with historical failure data to optimise valve reliability. Using advanced diagnostic tools, we track wear patterns, actuator performance, and seal degradation, enabling predictive maintenance scheduling. Customised software tracks maintenance histories, spare parts inventory, and recertification deadlines, reducing total cost of ownership by up to 40% while maximising uptime.
Backed by OEM certifications and a global spare parts network, we guarantee your valves operate flawlessly across their lifecycle—from commissioning to decommissioning.
With decades of experience across rotating equipment and pressure systems, Terrawatt is Nigerias trusted partner for valve lifecycle management. Were certified to handle everything from manual gate valves to automated control valves, pressure relief valves, and more.
Our mobile valve repair units and in-situ testing capabilities make us field-ready for any plant or offshore challenge.
Valves are the gatekeepers of your operations. When they fail, systems stall. Our valve maintenance service includes inspection, repair, testing, and full overhauls—restoring critical components across process plants, refineries, FPSOs, and flow stations.
We specialize in predictive and preventive maintenance, pipeline integrity, flow measurement, and advanced offshore inspection solutions, delivering measurable results in even the most demanding environments.
With Terrawatt, you reduce leak risks, extend valve life, and minimize unscheduled downtime.
We work with energy companies, manufacturers, and EPC firms to deliver fast, effective, and traceable valve servicing that supports reliability-centered maintenance programs.
