Inspection & Non-destructive Testing

We offer a comprehensive range of conventional NDT services, including:

  • Visual inspection incl. hangers and supports, hot and cold walk down
  • Laser mapping incl. piping systems and turbine rotors
  • Metallographic replication
  • Magnetic particle (MPI)
  • Dye penetrant (DP)
  • Boroscopy
  • Rotational inspection
  • Ultrasonic testing (UT) incl. wall thickness and oxide thickness measurement
  • Phased array ultrasonic testing (PAUT)
  • Remote field eddy current testing (RFET)
  • Pulsed eddy current (PEC)
  • Low frequency electromagnetic testing (LFET)
  • Balanced field electromagnetic testing (BFET)

This in addition to our advanced inspection services, including Electrical Discharge Sampling Equipment (EDSE), Integrity Scanning Force Microscope (I-SFM).

Risk Based Inspection & Maintenance

Our Risk Based Maintenance (RBM) procedure known as ‘Riskfit’ is used to identify and measure the risk areas. This allows optimised allocation of inspection and maintenance resources.

Reliability Centred Maintenance

Reliability centred maintenance (RCM) is an engineering framework that uses predictive maintenance techniques to empirically devise optimum maintenance regimes with greater reliability and cost efficiency in operation. We design and implement RCM programs for plants and major critical systems, or review and update existing programs, for optimum plant performance.

Defect & Crack Assessment

We offer defect assessment for high temperature plant components including pressure vessels, piping, and turbines. We have also developed our own defect assessment software ‘Crackfit‘, in collaboration with European industry, based on the internationally recognised High- temperature Defect Assesment (HIDA).

Fitness for Service

We assess the fitness for service of plant components and material under operating conditions, which can confirm that a material or component is safe to use, give advanced warning of in-service failures and resolve disputes between suppliers and operators.

On-Line Monitoring

On-line monitoring represents an economic means of practically assessing the true condition of plant or equipment in-service. We can identify optimal locations and techniques; install sensors, (incl. thermocouples and strain gauges) and complete data acquisition and analysis. We also have developed cutting-edge Electrical Potential Drop method.

Combined Cycle & Heat Recovery Steam Generators

Combined-cycle and heat recovery steam generator (HRSG) units lead a life complicated due to rapid starts, thermal transients, cycle chemistry issues, and improperly designed attemperator systems. We help clients deal with the resulting tube failures, flow-accelerated corrosion, piping expansion damage, weld cracks, and other consequences as well as training to improve the plant performance.

Plant & Asset Integrity

Our asset integrity Services assist clients in making informed decisions on the operation and maintenance of their plant (including pressure parts, boilers, turbines etc.) and to manage the risks their operations place upon the assets they own or operate.

Stress Analysis

We offer in-house finite element (FE) modelling of plant components. FE modelling can help in several circumstances – at the design phase, when looking for stress concentrations and deciding the placement of welds, and in life assessment to determine stresses operating in more complex geometries such as headers, rotors etc.

Probabilistic Life Assessment

We provide realistic estimates of component remaining life. Our probabilistic life assessment methodologies provide more accurate results than the more commonly used deterministic life assessments.

Vendor Qualification

Our vendor qualification service helps our clients focus on the complete elimination of any deficiencies in design, manufacturing, or processing. This ensures that plant owners and operators are confident that the equipment entering service will perform as intended by the design.
