Renan Silva Gonçalves
This work presents a reliability case applied to a vessel, highlighting a failure analysis that led to the development of more effective actions. Improvements included reviewing the FMEA (Failure Modes and Effects…
Calil Silva
To define the spare component pool for an off-highway truck fleet operating at a copper mine — assuming that a refurbished component returns as good as new — an LDA study was performed to project the probability…
Dales Fernandes Martins
We developed an algorithm to provide a way to count the number of critical decentralized-load events occurring monthly on large haul trucks, enabling actions to reduce their incidence. The solution expands…
Eduardo Felipe Andrade Gonsalves
Maringá Ferro-Liga is a steel-industry company that produces high-carbon manganese alloys. Seeking greater market competitiveness, its maintenance department implemented Reliability Engineering with a maintenance…
Dyulia Rossi Fiorio
Reliability-Centered Maintenance is a major ally in equipment-maintenance processes. It is used to optimize processes, reduce costs, support decision-making, analyze risks and increase equipment productivity and…
Joselma Ramos Da Silva
The grinding process consists of removing small imperfections and reshaping the rail profile. This process is extremely important because rails are currently the largest cost item in railway operations. On the EFC,…
Wilber Silva Leonel Junior
This work presents a failure analysis of the drive-shaft bearing on John Deere CH570 sugarcane harvesters. The study was motivated by recurring bearing failures during the 2023/2024 sugarcane harvest. In addition to…
Octavio Ferrari
The reliability study for fuel pumps was conducted in the context of iron-ore operations at Carajás – Serra Norte, the world’s largest open-pit iron-ore mine. The evaluated component is the Fuel Transfer Pump for the…
Diego Henrique Oliveira Costa
This work was developed to study degradation of sugarcane-harvester elevator chains, with the objective of conducting a feasibility assessment to determine which brand should be adopted by the company.
Pedro Thyago Ataide Rodrigues
The objective of this work is to perform a failure analysis of the diesel engine in an EVO locomotive fleet. In the event analyzed, the diesel engine ran away, resulting in damage to internal components. The event…
Italo Clemente Rodrigues
The objective of this work is to analyze the reliability evolution of a vibrating screen in the primary-screening system at Vale’s S11D unit after implementation of design improvements. The methodology was based on…
Leonardo Borges Fernandes da Silva
The work addresses the study and application of Reliability-Centered Maintenance (RCM) and system reliability with the objective of improving performance — Physical Availability and MTBF — of the single-circuit long-distance belt-conveyor system at the S11D iron-ore mine.
Jéssica Medelles Vasques de Souza
To increase operational maturity and ensure process stability and independence, a comprehensive reliability-analysis approach was adopted, combining qualitative and quantitative methods. These studies made it…
Luiz Claudio Henriques da Silva
After an accident in 2018 caused by failure of a drilling-winch braking system, a process was introduced for periodic brake-capacity testing, with the frequency initially defined based on the technical team’s…
Alan Ricardo Moreira Razoni Junior
Analysis of component failure probabilities, forecasts of preventive, condition-based and corrective interventions, spare-pool requirements and supply lead times to develop the maintenance-materials budget with the objective of operationally ensuring achievement of the copper-movement target.
