Failure Analysis & accident investigation Corrosion engineering Fire investigation Expert witness in litigation Design & structural analysis Condition assessment
Corrosion occurs in all industries from automotive and aerospace to infrastructure, construction, marine, petroleum, power, paper making, food processing, bioengineering, and pharmaceuticals. Corrosion is costly, dangerous, wasteful, and unsightly in some cases. It can be predicted, controlled, and even avoided.

UTC team consists of experts with more than 35 years of relevant industrial and research experience as well as qualifications. The key staff has successfully led and completed thousands of projects in forensic analysis, accident investigation, failure analysis (FA), condition assessment for aerospace, marine, petrochemical, electronic and microelectronic, construction, amusement, oil & gas, transportation industries and governmental agencies including Ministry of Defence (Singapore), Republic of Singapore Air Force (RSAF), Defence Science and Technology Agency (DSTA), Singapore Civil Defence Force (SCDF), Ministry of Manpower (MOM), Hyundai Engineering and Construction (Korean), Public Utilities Board (PUB), The Straits Times, SBS Transit, High Court, State Courts, China Taiping Insurance, Rajah & Tann, WongPartnership, Universal Terminal, Singapore Navy, SMRT, RWS, Shell, ST Aerospace, Eagle Services Asia, SIA Engineering, HP, Dell, ST Marine, Takenaka Corporation (Japan) and Sembawang Shipyard, etc.

Typical projects

    Our experts had successfully accomplished thousands of failure analysis and accident investigation projects, some typical cases related to corrosion are listed as follows:

  • Failure analysis on crevice corrosion of roller coaster vehicle spindle
  • Forensic investigation on stainless steel wire rope snapping (fracture by stress corrosion cracking) of mass rapid transport system/ subway accident
  • Failure analysis on aircraft air foil corroiosn
  • Investigation on paint and coating failures
  • Failure analysis on corrosion of large batch of doors
  • Investigation on propeller bolt (fractured by corrosion fatigue) of hovercraft accident
  • Forensic investigation on cooling pipe corrosion of jack-up rig
  • Failure analysis on manhole corrosion damage
  • Forensic investigation on corrosion and fracture of galvanized bolts in roller coaster track

Objectives

    Corrosion engineering will:

  • Determine root cause(s) of corrosion.
  • Find out mechanism(s) of corrosion.
  • Recommend counter measures and solutions to prevent or minimize corrosion.
  • Support litigation/court hearing on liabilities related to failures and accidents
