Upholding safety in future energy systems: The need for systemic risk assessment

This paper argues that energy systems are becoming increasingly complex, and illustrates how new types of hazards emerge from an ongoing transition towards renewable energy sources. It shows that the energy sector relies heavily on risk assessment methods that are analytic, and that systemic methods provide important additional insights.Acase...

A fuzzy multi-attribute HAZOP technique (FMA-HAZOP): Application to gas wellhead facilities

Hazard and Operability analysis (HAZOP) is a popular technique for hazard identification and risk ranking in hazardous facilities. Conventional HAZOP, however, has some drawbacks: (i) it considers a limited number of risk factors, i.e., only the frequency and the severity of hazards; (ii) it assumes equal weights for the risk factors, thus...

Identification of the information needs for sewer asset management by assessing failure mechanics

Asset management is a prerequisite for maintaining the required level of serviceability of urban drainage systems. The required asset management effort to achieve a certain level of service is unclear due to sewer systems process and structure complexity. One of the main questions of asset management is what kind of information is needed, and...

Identificatie van de benodigde informatie voor het beoordelen van faalmechanismen bij het rioleringsbeheer

Rioleringsbeheer is een eerste vereiste om het gewenste niveau van functioneren van de riolering te behouden. Welke inspanning op het gebied van rioleringsbeheer nodig is om een bepaald niveau van functioneren te bereiken is onduidelijk, omdat zowel de processen in als de structuur van de rioolstelsels complex zijn. Een belangrijke vraag hierbij...

On Track in Reducing Uncertainties: Exploration of the Value of the HAZOP Methodology as a Tool for Decision Makers at ProRail involved in Multi-Actor Decision Making

ProRail is the railway management company of the Netherlands. It is responsible for the construction, maintenance, management, and safety of the Dutch railway system. ProRail has as a goal an annual five per cent increase in the number of transported passengers up to 2020. This goal cannot be reached with the current way of transporting...
