Real World Examples
Predictronics and a marine-diesel engine manufacturer – Predictive maintenance
Implementation: Predictronics Corporation worked with global marine diesel-engine manufacturer to develop predictive-maintenance solution for early detection and diagnosis of diesel engine failures operating in harsh marine environments. Engine health issues not addressed ahead of time can cause many challenges for engine owners and operators including unplanned downtime, inefficient maintenance schedules, lost profits, and wasted resources. Manufacturer provided Predictronics team members with large set of marine vessel fleet data, enabling team to use extensive experience in health monitoring for industrial applications to detect early symptoms of diesel engine failure through time-series anomaly detection approach. Key indicators of diesel engine failure emerged from analysis results pinpointing specific components in need of repair including seawater pumps, exhaust sensors, piston valves, and turbochargers.
Results: Predictronics’ data-driven solution predicted seawater pump, exhaust sensor, and piston valve issues days in advance enabling manufacturer to prevent unplanned failures in marine diesel engines for customers. Analysis improved maintenance scheduling for turbocharger, another element within engine causing overall decline in performance. Health assessment models developed by Predictronics not only predicted failure but also reduced need for manual review of data and provided better insights to craft more optimized maintenance schedule saving engine customers time and money and resources. Manufacturer could potentially expand and scale solution in future to provide remote health monitoring services for engine customers, illustrating how advanced diagnostics and maintenance-strategy skills like those in this course can improve reliability and maintenance efficiency and demonstrating how structured condition monitoring, troubleshooting, and maintenance-strategy skills taught in course can cut downtime and repair costs and operational risk for fleets and plants.
U.S. nuclear power plant – Optimising EDG preventive maintenance
Implementation: U.S. nuclear power plant conducted comprehensive review of Emergency Diesel Generator (EDG) preventive-maintenance (PM) work orders accumulated over 12 to 18 years to verify whether recommended maintenance activities were still applicable and justifiably necessary. Review focused only on PMs with frequency of three years and included historical performance data over last 18 years. Analysis examined past and current findings for degradation, out-of-tolerance conditions, and failures to determine which PMs could be justifiably modified in frequency and activity description to save owner time and money while maintaining safety requirements. Properly optimized plan drew upon features of several maintenance theories with condition monitoring program reflecting tradeoff of EDG reliability between preventative maintenance and EDG failure.
Results: Study determined that approximately 80 percent of 47-plus PM tasks per EDG (150 total) within scope of review were justifiably qualified to have frequency extended. Optimization produced immediate saving of USD 225,280 and estimated future savings of approximately USD 450,000 every six years. Results demonstrated value of maintenance engineers who understand diesel systems well enough to rationalize PM tasks based on evidence exactly mindset this course builds showing how disciplined and data-informed PM programme built on solid understanding of diesel systems and failure modes and inspection points as covered in course can maintain reliability while significantly reducing life-cycle maintenance cost. Study validated that non-documented savings such as warehouse stock price, planner time, scheduler time, workgroup review and brief time, operation clearance tag application and removal time, post-work supervisor review time, work package closure time, and trending review time could more than double calculated savings.
Heavy-duty diesel engine with EGR + SCR – Ultra-low NOx benchmark
Implementation: An experimental programme on heavy-duty four-cylinder diesel engine equipped with comprehensive aftertreatment system comprising diesel oxidation catalyst (DOC), diesel particulate filter (DPF), selective catalytic reduction (SCR), and ammonia slip catalyst (ASC) investigated NOx emission control and fluid cost balance. Study evaluated coordinated control of exhaust gas recirculation (EGR) and AdBlue dosing across multiple engine speeds (1600 and 2100 rpm) and loads (25, 50, 75, and 100 percent) to balance NOx emissions reduction with total fluid cost including diesel and AdBlue consumption. Research systematically examined effects of EGR valve opening on engine air flow rate, air-fuel ratio, brake-specific fuel consumption (BSFC), NOx emissions at engine outlet, exhaust temperature, and SCR carrier temperature, as well as effects of AdBlue rate on NOx emissions at SCR outlet, NOx conversion efficiency, and SCR temperature characteristics.
Results: Carefully coordinated EGR and AdBlue dosing achieved tailpipe NOx as low as 0.027 g per kW-h on FTP cycle satisfying California Air Resources Board (CARB) ultra-low NOx emission regulations. Study documented that as EGR valve opening increased, brake-specific fuel consumption increased and NOx emission at engine outlet decreased, while with increased AdBlue dosage NOx conversion efficiency gradually improved ultimately approaching near-zero NOx emissions. At 1600 rpm (100 percent load) when NOx emissions were reduced to zero, maximum fluid costs were 235, 223, and 218 g per kW-h under AdBlue-diesel price ratios of 1-1, 1-2, and 1-3 respectively. Research provided valuable guidance for EGR and urea control in diesel engines demonstrating how changes in EGR rate affect fuel consumption and exhaust temperature and after-treatment performance, underscoring why maintenance and diagnostics knowledge about EGR valves and after-treatment hardware and combustion taught throughout this course is critical for modern diesel-engine professionals and illustrating how training technicians and engineers in combustion and EGR effects and after-treatment operation and emissions diagnostics helps organizations comply with tightening emission regulations while controlling fuel and urea costs.
