2020	Canadian Natural Resources-JPM Surge Feed Conveyor	Canada	Resolve issues related to VFD tuning that OEM unable to fix during commissioning
2020	Suncor-Fort Hills	Canada	Install strain gauges and investigate failure on surge feed conveyors
2017	Chinalco-Toromocho	Peru	Install strain gauges and investigate failure on CV003 Downhill
2015	Neptune Terminal, Vancouver	Canada	Investigation of the cause of abrasion wear in the inner section of the conveyor closure.
2015	BHP – Escondida Upgrade	Chile	Audit of the overland belt design and diagnosis of the winch control.
2015	Glencore	Australia	FEA analysis of belt wear and lamination
2015	Essroc, PA	United States	Analysis to determine the cause of repeated pulley failures.
2013	Ibberson EGT Grain Terminal	United States	Forensic analysis to determine the cause of the site failure and recommended corrective action.
2013	Muskeg River – Shell Oil Sands	Canada	Forensic tests to determine cause of overland belt failure 101
2010	Elkview	Canada	Forensic analysis of runaway conditions due to brake failure.
2000	Los Pelambres Repower	Chile	Transport system design audit to increase tonnage.
1997	Nesher Israel Cement	Israel	Ground transporter audit using dynamic and forensic tests.
1996	Phosboucraa	Morocco	Improve system reliability and availability.
1990	Syncrude. Fort McMurray	Canada	CDI predicted shaft failure at the lockout device interface.
1990	Southern Ohio Coal	United States	CDI predicted shaft failure at the lockout device interface.
1990	Selby British Coal	United Kingdom	Forensic evidence and dynamic analysis to correct a design flaw.
1989	Palabora	South Africa	Fatal pulley drum defect was determined by use of FEA prior to fabrication.
1988	Kennecott – Bingham Canyon	United States	After startup, the drum of a tensioner pulley failed in the housing. CDI was not involved in the design of the pulley. CDI investigated the failure of the shell and determined that the shell is sub-designed. An engineering audit of the remaining pulleys was performed, using the CDI failure criteria, and similar deficiencies were found in the high tension pulleys. These pulleys failed three months after our audit.
1986	Quintette Hydraulics	Canada	The overall system was experiencing controlled braking runaways, gear reducer and pulley failures, and numerous other problems. CDI was contracted to identify, analyze, and correct the problems.
