We deliver cutting-edge automated flow measurement systems engineered for precision and reliability in the most demanding oil, gas, and multiphase flow environments. Utilising smart metering technology—including Coriolis, ultrasonic, and turbine meters—our solutions provide real-time data acquisition, ensuring accurate volumetric and mass flow calculations. Integrated with advanced diagnostics and cloud-based analytics, these systems empower operators to optimise production rates, minimise measurement uncertainty, and reduce fiscal losses across upstream, midstream, and downstream operations.

We deliver comprehensive valve maintenance solutions designed to ensure reliability, safety, and peak performance across oil, gas, and petrochemical operations. Our certified technicians specialise in all valve types—including gate, globe, ball, check, and safety valves—across ANSI pressure classes and severe service conditions. From routine inspections to complex overhauls, we implement preventive, predictive, and corrective maintenance strategies to minimise downtime, prevent leaks, and extend service life while adhering to API, ASME, and ISO standards.

We specialise in critical I-tube inspections for umbilicals, risers, and subsea infrastructure, ensuring structural integrity and uninterrupted operations in offshore oil and gas systems. Using advanced remotely operated vehicles (ROVs) paired with non-destructive testing (NDT) methods like ultrasonic testing (UT) and eddy current arrays, we assess corrosion, fatigue, and mechanical damage in I-tubes—key components connecting FPSOs to subsea production systems. Our proactive inspections prevent catastrophic failures, safeguarding against costly downtime in harsh marine environments.
