A data-driven approach to improve control room operators' response
(Peer reviewed; Journal article, 2021) -
A Guideline for the Dynamic Barrier Management Framework Based on System Thinking
(Journal article; Peer reviewed, 2019)Accident investigations in process industry indicate that inadequate barrier management has been one of the main causes of many major accidents. Barriers degrade over time and at different rates, and these degradations may ... -
An Integrated Approach to Support the Dynamic Risk Assessment of Complex Industrial Accidents
(Journal article; Peer reviewed, 2019)Recent major accidents in the offshore oil and gas (O&G) industry have showed inadequate assessment of system risk and demonstrated the need to improve risk analysis. While direct causes often differ, the failure to update ... -
An Approach to Update the Failure Rates of Safety Barriers Based on Operating Experience
(Peer reviewed; Journal article, 2022)Hazardous events in process plants like the leakage of dangerous substances can result in severe damage, and such an event is often defined as the TOP event of a fault tree analysis (FTA) in a quantitative risk analysis. ... -
Business intelligence for the analysis of industrial accidents based on MHIDAS database
(Peer reviewed; Journal article, 2021)Reducing the frequency and severity of accidents in industrial processes is a continuous open challenge. Learning from previous events represents a crucial instrument to ensure an improved design of industrial plants, ... -
Comparison of risk-based maintenance approaches applied to a natural gas regulating and metering station
(Peer reviewed; Journal article, 2020)In the last decades, many researchers have directed their efforts towards the safety improvement of plants where hazardous substances are processed or handled. This attitude has led to developing strategic plans for ... -
Computational Fluid Dynamics Modeling of Liquid Hydrogen Release and Dispersion in Gas Refuelling Stations
(Peer reviewed; Journal article, 2021) -
Cryogenic Hydrogen Storage Tanks Exposed to Fires: a CFD Study
(Peer reviewed; Journal article, 2022)Hydrogen is one of the most suitable candidates in replacing heavy hydrocarbons. Liquefaction of fuels is one of the most effective processes to increase their low density. This is critical especially in large-scale or ... -
Design and Optimization of an Emergency Auto-thermal Burner for Liquid Hydrogen
(Peer reviewed; Journal article, 2022)The adoption of hydrogen has been largely indicated as a feasible solution to support society in achieving its ambitious targets for a low-carbon future. The increased knowledge in liquefaction techniques has encouraged ... -
Development of a Protocol for the Systematic Analysis of Events at Hydrogen Refuelling Stations
(Peer reviewed; Journal article, 2023) -
Development of Tools Enabling the Deployment and Management of a Multi-Energy Renewable Energy Community with Hybrid Storage
(Journal article; Peer reviewed, 2021) -
Digital Twin Concept for Risk Analysis of Oil Storage Tanks in Operations: a Systems Engineering Approach
(Peer reviewed; Journal article, 2022)This paper presents an approach to develop a risk monitoring tool for oil storage facilities. The suggested approach is derived from the existing dynamic risk analysis (DRA) methods and the digital twin concepts. One of ... -
Dynamic Risk Analysis from the Perspective of Life Cycle Approach in Iec 61508 and Iec 61511
(Peer reviewed; Journal article, 2021)Dynamic risk analysis (DRA) aims to provide updated risk levels during operations of a hazardous facility. One of the main objectives of performing a DRA is to support day-to-day operational decisions, primarily for ... -
Experimental Investigation into the Consequences of Release of Liquified Hydrogen onto and under Water
(Peer reviewed; Journal article, 2022)Large-scale experiments have been performed to investigate the possible consequences of realistic amounts of liquified hydrogen (LH2) encountering water. The experiments aimed at simulating an accidental release of LH2 ... -
Fragments Generated during Liquid Hydrogen Tank Explosions
(Peer reviewed; Journal article, 2023)Liquid hydrogen (LH2) may be employed to transport large quantities of pure hydrogen or be stored onboard of ships, airplanes and trains fuelled by hydrogen, thanks to its high density compared to gaseous compressed hydrogen. ... -
Hydrogen Fireball Consequence Analysis
(Peer reviewed; Journal article, 2020)A fireball may occur after the catastrophic rupture of a tank containing a flammable substance such as a fuel, if an ignition source is present. The fireball is identified by the combustion of the flammable cloud created ... -
Identification of Consequences of Failure for Hydrogen Equipment
(Journal article; Peer reviewed, 2023)Hydrogen has not only the potential of tackling climate-related issues by replacing fossil fuels, but it also plays a main role in the energy transition which will have several geopolitical implications. According to the ... -
Integration Between Occupational and Process Safety: Existing Approaches and Challenges for an Enhanced Framework
(Peer reviewed; Journal article, 2020)Occupational safety is traditionally managed distinctly from process safety. The former puts the emphasis on high frequency and low consequence incidents, and refers to hazards that could provoke human consequences. In ... -
A Machine Learning Approach to Analyze Natural Hazards Accidents Scenarios
(Peer reviewed; Journal article, 2022)Climate change has contributed to an increasing frequency and severity of natural hazards accidents over recent years, and the increasing trend is expected to continue and escalate. Globally, demographics are changing and ... -
A machine learning approach to predict chattering alarms
(Peer reviewed; Journal article, 2020)The alarm system plays a vital role to ensure safety and reliability in the process industry. Ideally, an alarm should inform the operator about critical conditions only and provide guidance to a set of corrective actions ...
