What Is Failure Analysis Service ?

Failure analysis service (or failure investigation service) are consultation services which adopt systematic analysis approach and scientific techniques to determine root cause(s) and mechansim(s) of failure and provide counter measures to prevent similar failure or accident recurrence. Failure analysis services are demanded by companies and governments from not only Singapore but also other countries.

Failure analysis experts are sometimes summoned to the Court and act as failure analysis expert witness testifying in the Court to present expert opinions and evidences in case the parties involved in the failure or disputes on the responsibilities ( litigation). For more details of expert witness, please refer to EXPERT WITNESS SERVICES.

Failure analysis is often called as engineering failure analysis, including mechanical failure analysis or stress failure analysis, component failure analysis, electrical failure analysis and material failure analysis. In case of damages involved in equipments or facilities, failure analysis can be called damage analysis (or damage investigation). Inspection is often involved in failure analysis or related investigation.

    • What Is Effective Failure Analysis ?

    Some failure analyses are not conclusive, or could not determine the failure cause(s) or even wrong conclusion. Only those failure analyses which make reliable conclusions supported by valid evidence(s), facts and sound scientific & engineering principles are called effective failure analysis.

    Effective failure analysis services can not only enhance reliability and safety, but also improve product quality and reduce operational cost & down time of facilities. UTC's scientific and engineering experts in Singapore provide effective failure analysis with relaible, fast and cost-saving failure analysis results beyond Singapore, draw reliable conclusions and recommend effective measures, based on solid evidences, sound scientific & engineering principles, and logical inference.

    How to validate effective failure analysis

    Effectiveness of failure analysis and accident investigation can be evaluated from following aspects:
  • Explain all observed phenomena and findings or data.
  • Feedback from the clients.
  • Peer review.
  • The effect after investigation and implementation.
  • Court acceptance
    • Only the evaluations from all the above aspects are positive, such failure analysis or accident investigation can be considered as effective.

    Key elements for effective failure analysis


  • Qualified investigator(s)
  • Good track records
  • Proven analysis or investigation procedure and approach
  • Multi-discipline and cooperative team
  • Adequate analysis and investigation tools – instruments
  • Impartial and objective mind

    • CORE of effective failure analysis is selecting competent failure anaysis expert.

    What Is Forensic Investigation and Analysis ?

    Forensic investigation and analysis is to apply scientific knowledge and methodology to legal issues and / or criminal investigations of the subject cases, thus it can assist the Court or litigation for justifications. Therefore, forensic investigation and analysis sometimes are actually extension of failure analysis services. The focus of failure analysis is on determining failure cause(s) & failure mechanism(s) while the focus of forensic investigation and analysis is on providing traceable evidences for clarifying responsibility and liability of the failures and accidents.

    Why Choose UTC's Failure Analysis Services ?


    How to conduct failure analysis ?

    Failure analysis or sometimes called root cause analysis may use following techniques:
    • Fishbone diagram, i.e. Causes and effects diagram

    • Five why questioning, i.e. Asking why, why, why qestions until fundamental causes are identified

    • Fault tree analysis (FTA) is a top-down, deductive failure analysis

    • Failure modes and effects/criticality analysis (FMEA or FMECA), list possible failure modes are defined; the effects and probabilities of those failures

      • In general, a proper failure analysis procedure shall be adopted during failure analysis process, so that failure analysis and investigation can be proceeded step by step.
      1. Collecting relevant background information on the failure.
      2. General survey on the failure site and selecting specimens or samples for further examination and investigation.
      3. Visual and macroscopic examination on selected samples or specimens relevant to failure.
      4. Analysis and inspection on samples or specimens with non-destructive techniques.
      5. Examination and analysis on samples or specimens with destructive techniques.
      6. Simulation analysis or simulation experiment.
      7. Data analysis on the analysis & investigation findings and logical inference.
      8. Report preparation to inculde failure analysis findings and conclusions.

    UTC Expert Witness for Recent Litigation and Court Cases

    A mobile crane toppled when lifting an 40 feet container, resulting in damages amount to several hundred of thousands dollars. UTC was engaged to investigate the accident causes and as expert witness in legal litigation. According to the court record, the Judge accepted our conclusion that the crane toppled was due to defective/malfunctional AML system.

    A heavy gate toppled during installation and caused a worker death. UTC was engaged by MOM for accident investigation and as expert witness in this court case. According to Straits Times and Channel NewsAsia's reports, the court ruled that the contractor was fined S$280,000 for fatal gate toppling. The contractor filed appeal, but lost the appeal and punishment was increased from S$280,000 to S$330,000 for fatal gate toppling. UTC had successfully determined the root causes of the accident and testified in the court hearing by providing solid evidences with scientific methodolody.

    One crane collapsed in a construction site, which severely damaged the nearby plant facilities and workshop during lifting operation. China Taiping Insurance engaged UTC to investigate the accident and as expert witness in legal suit. We successfully determined the root causes of the accident. Shortly after receiving our report, the case was settled favourably before court hearing.
