Corrosion Engineering in Singapore

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
