Failure Analysis and Forensic Accident Investigation

Failures and accidents often occur on products, facilities, infrastructures, production line and work sites in various industrial sectors, not only resulting in huge economic loss but also fatalities in some cases. It’s critical and imperative to determine the failure cause(s), failure mechanism(s) and provide counter measures to prevent similar failure(s) recurrence in future. Effective failure analysis (FA) and accident investigation can not only enhance reliability and safety of products and infrastructures, but also improve product quality and reduce operational cost and down time of facilities so that improve productivity.

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.
