Aide Memoir for Geophysical Risk AssessorsIAGC/OGP Workshop
September 2007
E. Sixma – SIEP
Introduction - 1
• Risk Assessment and the use of a Risk Assessment Matrix (RAM) require a memory function.
• Risk assessment for low frequency, high potential incidents (Fatalities) needs to be done on the basis of collective industry experience.
• Need a repository for Industry experience.
“Aide Memoir for Geophysical Risk Assessors”
• Proposed to April 2006 HSE forum and agreed action.
• Work in progress, further contributions invited!
Introduction - 2
• Prime objective
– Tutorial for next generation (“mandatory reading material”)
• Avoid repeats and re-inventing the wheel the hard way !
– Reference database for use with RAM, capturing industry experience
• Answer the question “Has this happened in the industry ?”
• Side benefits
– Improve statistical insight
– Identify “Rare” but real risks
• Further use
– Cross check when developing guidelines, e.g. OGP 317 and IAGC HSE manuals
• Have we covered all known risks that have resulted in a fatality in the past?
Data base content and structure
• Excel spreadsheet
– Sort and Search functionality
– Graphical analysis tools
• Fields used:
– Record number for reference (invariant to sorting)
– Year
– Number of fatalities in event
– Single or Multiple (>3) fatality
– Summary accident description
– Comments, identified root causes if available
– Geophysical or Other operation
– Land / TZ / Marine
– Type of accident, broad standard classification
– Type of accident, more detailed classification
– 3 Keyword fields
Data base content and structure
• Not included
– High potential Near Misses
– Common vehicle accidents
• Limit size and effort, but may be we should add these too ?
– Country (exception: bee attacks)
– Company or Contractor information
– Information about victims, such as gender, age, time employed etc.
Data base sources
• OGP annual reports since 1980
• IAGC and CAGC data and HSE alerts
• STEP change Sadie database alerts
• WesternGeco
• CGG
• Many experienced individuals
– Reports “from memory” accepted from reliable sources
– All fatal accidents in Geophysics that we could find (except vehicle accidents)
– Relevant accidents from other E&P operations that “could easily have happened in Geophysical Operations”
Data base
• So far captured:
– Geophysical operations:
• 379 fatalities from 219 accidents
– Other
• 217 fatalities from 181 accidents
• Please contribute and send info on further fatal incidents, not yet in the data base, to E. Sixma ([email protected])
• Plan to “package” data base with some introductory and explanatory text and to publish as OGP report towards the end of 2007.
• Excel data base will also remain available through OGP / IAGC websites.
• Update database yearly
Graphical analysis
• Courtesy Michael Denkl, WesternGeco
• Pivot Charts
– By type of accident
– “Zoom in” on some classes of accidents, e.g. Drowning
– By year
• Can select on
– Number of Fat. and S/M: Single / Multiple
– A/G/O All, Geophysical or Other
– Type of operation Land / TZ / Marine
• Note: pivot charts “skip” years in which no event is recorded, slightly impairs visual analysis.
