Quantitative Risk Analysis (QRA) – Part 2
In industrial safety engineering, the feasibility of an escape route in accident scenarios is determined by the fundamental equation for life safety: ASET > RSET. In this equation, ASET (Available Safe Egress Time) is the time available for safe evacuation before the environment becomes untenable, and RSET (Required Safe Egress Time) is […]
CFD Simulation Analysis of Flow Around an Urban Vehicle
The CFD (Computational Fluid Dynamics) simulation applied to the design of the BOTO hybrid urban prototype yielded a drag coefficient (Cd) of 0.20. Using a 3D scanning methodology for scaled-down models, the study identified critical points of flow separation and proposed improvements to the rear fairing. The final result represents […]
Vibration in Industrial Conveyors: Diagnosis, Analysis, and Solutions
Diagnosis and analysis of vibration in industrial conveyors, identifying causes, structural risks, and solutions to improve reliability.
Quantitative Risk Analysis (QRA) – Part 1
Quantitative Risk Analysis (QRA) is a scientific methodology that calculates the residual risk of an operation using the mathematical relationship between the probability of failure (P) and the severity of its consequences (C), as represented by the classic equation: R = P × C. In highly complex safety engineering, CFD (Computational Fluid Dynamics […]
Fatigue failure in an automotive component
Introduction Fatigue failure in automotive components is common in the industry and is also present in our daily lives. The automobile is perhaps the machine most widely used by humans today and contains numerous mechanical components—mostly made of metal—that are susceptible to fatigue failure. In general, fatigue failures […]
Technical Due Diligence
Technical Due Diligence (TDD) is an independent engineering audit conducted in the context of mergers, acquisitions, and investments in industrial or infrastructure assets. Its primary objective is to mitigate the caveat emptor principle (the buyer’s duty of care) by identifying hidden risks, structural defects, and physical liabilities that could compromise […]
Fracture Mechanics applied to Structural Integrity industrial equipment
Introduction First, structural failures in industrial equipment are not always associated with excessive loads or extreme events. In many cases, metal structures fail after long periods of operation under stresses below the material's yield strength, without showing visible signs of prior deterioration. This type of failure is directly related to [...]
Structural Integrity Thickener: Inspection and Evaluation
Ensuring the safety and durability of large-scale thickeners requires integrated and accurate diagnostics. In this study, Kot Engenharia a comprehensive structural assessment of a concentrate thickener that exhibited cracks, leaks, and waterproofing failures. Through a detailed visual inspection using the GUT Matrix classification, field tests (carbonation, sclerometry, ultrasonography […]
High-strength bolts: design and installation
The proper specification and installation of high-strength bolts (such as ASTM A325, A490, and ISO classes 8.8 and 10.9) are essential for mitigating vibrations, fatigue, and corrosion in industrial metal structures. According to the criteria of ABNT NBR 8800:2024, structural connections require a practical understanding of the relationship between torque (indirect rotational force) […]
Structural Integrity: what is it and how to apply it?
“I need to start a Structural Integrity journey Structural Integrity my organization, given the current state of my assets. But where should I begin?” This question comes up frequently in our daily lives, usually from technicians, engineers, managers, directors, and other professionals whose mission is to maintain the Structural Integrity assets and […]
