Remote Control – The art of delivering successful workshops remotely
Good practice for the effective running of high quality, remote workshops.
A hazard missed is a hazard uncontrolled
"The identification of areas of vulnerability and of specific hazards is of fundamental importance in loss prevention. Once these have been identified, the battle is more than half won." (Frank Lees)
Applying modified HAZOPs to well testing
Hazard and Operability studies (HAZOPs) are widely used in the oil and gas industry to examine process systems, but less so for drilling, completion and well testing activities. This is typically because the traditional HAZOP applies process-based guidewords to Process & Instrumentation Diagrams (P&IDs), whereas drilling, completion and well testing activities are more procedurallybased and also use Well Test String Diagrams.
Lessons learned from 100s of HAZOPs…or how to get the most out of the HAZOP process
In the last issue of RISKworld we introduced some of the methods available to identify hazards associated with a process or design. One of the best known methods is the HAZOP (Hazard and Operability) study, which is an extremely useful technique for brainstorming hazards in a structured way.
Secrets of successful HAZOP scribing
Hazard and Operability (HAZOP) studies are one of the most commonly used hazard identification methods in the high hazard process industries. Experienced HAZOP leaders are crucial to the success of the study, bringing together their technical knowledge and team facilitation skills to ensure a comprehensive and accurate study. But the quality of the study, especially the output, is also highly dependent on the quality of the reporting, which is the work of the HAZOP scribe.
