Recent regulatory requirements for shipping emissions control have led to the adoption of Liquefied Natural Gas (LNG) as a marine fuel and design LNG-fuelled vessels. Considering potential safety implications due system failure/unavailability, this study aims at analysis low-pressure LNG feeding using novel model-based methodology. The proposed methodology is based on functional modelling, lead...

While use of LEDs in fiber optics and lighting applications is common, their use in medical diagnostic applications is very rare. Since the precise value of light intensity will be used to interpret patient results, understanding failure modes is very important. We used the Failure Modes and Effects Criticality Analysis (FMECA) tool to identify the critical LED failure modes. Once the critical ...

There are four primary accident types at steel building construction (SC) projects: falls (tumbles), object falls, object collapse, and electrocution. Several systematic safety risk assessment approaches, such as fault tree analysis (FTA) and failure mode and effect criticality analysis (FMECA), have been used to evaluate safety risks at SC projects. However, these traditional methods ineffecti...

Automated Guided Vehicles (AGVs) are being increasingly used for intelligent transportation and distribution of materials in warehouses and auto-production lines. In this paper, a preliminary hazard analysis of an AGV’s critical components is conducted by the approach of Failure Modes Effects and Criticality Analysis (FMECA). To implement this research, a particular AGV transport system is mode...

INTRODUCTION Patients with sickle cell disease (SCD) often seek care in emergency departments (EDs) for severe pain. However, there is evidence that they experience inaccurate assessment, suboptimal care, and inadequate follow-up referrals. The aim of this project was to 1) explore the feasibility of applying a failure modes, effects and criticality analysis (FMECA) in two EDs examining four pr...

Traceability information systems in food supply chains (FSCs) can suffer from loss, and this cause safety crises economic downturns around the world. Information loss happens as a result of inefficiencies material flows caused by vulnerabilities associated with either internal traceability individual FSC operators and/or external between them. A structured comprehensive approach to identify ana...

Failure mode and effects analysis (FMEA) has been proven to be an effective methodology to improve system design reliability. However, the standard approach reveals some weaknesses when applied to wind turbine systems. The conventional criticality assessment method has been criticized as having many limitations such as the weighting of severity and detection factors. In this paper, we aim to ov...
