Forensic Failure Analysis Services
Expert Witness
from Singapore

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 provide effective, relaible, fast and cost-saving failure analysis services beyong Singapore, based on solid evidences, sound scientific & engineering principles, and logical inference.

What Is Failure Analysis Services ?

Failure analysis services (or failure investigation services) is consultation services in which adopts systematic analysis approach 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.

UTC was just awarded a peroid contract "1 year + optional 1 year of failure analysis services" from Nov. 2020 by Enterprise Singapore (ESG).

Failure analysis is often named 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 are involved in epuipments or facilities, failure analysis can be called damage analysis (or damage investigation) and inspection.

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. For more details of expert witness, please refer to EXPERT WITNESS.

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. 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 resposibility and liability of the failures and accidents.

    How to conduct failure analysis or failure investigation

    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.

    Effective failure analysis

    What is effective failure analysis

    After conducting failure analysis or accident investigation, the conclusion could be wrong, inconclusive or inrelevant, lack of logical or evidence, such kind of conclusion would be misleading, not only the analysis and investigation money as well as precise time are wasted, but also the failures or accidents could not be solved and prevented, it would further damage reputation and even litigation loss.

    The effective failure analysis must be comprehensive, logical, adapt scientificaly proven methods, and get right conclusions with solid evidences.

    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.

    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.
