 No clear trend
 2007, 2009, 2010 show peak within summer period
 No correlation with winter weather but sea fastening an ongoing observation issue

Devil in the detail –
2011 High Potential Example
• Scaffold Equipment stored next to BOP deck handrail
• Worker pulls scaffold board free from under scaffold tubes
• Scaffold tube rolls on top of other tubes towards handrail post
• Tube collides with handrail post, turns and the end slides through hand rail / kick plate
gap
• Scaffold Tube weighing 16Kg’s fell 12m to deck below
• Nobody was injured but high potential :
Q: would you walk past this storage arrangement ?

Summary
• Although statistics show an improving trend complacency is dangerous as high potential incidents are persistent
 need to keep the issue ‘live’ with offshore personnel
• DO Hazard Hunts are good at eliminating loose items but poor maintenance + incorrect use of equipment are frequent
causes of DO’s
• Basic issues still have the potential to hurt us
e.g. use of correct sea fastening
• Poor hazard recognition is a common theme across safety incidents
 Encourage ‘Fresh eyes’ to challenge assumptions
