It seems in the future we/organizers should be sharing this information quite readily, since it is a system that is being employed often and new people will be devising them. It would be much safer if there was a general awareness of where pitfalls have occured in practice, so preventitive measures could be taken and better systems planned out.
My opinion. What do you think?
Tyler,
What happened was the vertical distance between the buoys and the separation bar was a bit long, so the horizontal separation bar as well as the pulleys dipped too far below water. When you clip your lanyard to it, you're almost pulled underwater. The seas got pretty rough (rougher than 2003 Cyprus last day, I hear), so Annabel DID got pulled underwater intermittantly. She completed her dive, but things couldn't be fixed in time for the next competitor because of safety scuba's schedule.
Some remedies:
- Test the system in the same/similar condition before it goes Live. I was at last year's WRC to witness the rig incident as well as here, so we know the organizers don't always have the time to test everything. This is probably why there's the 'opener' (a non-athlete person who 'opens' the event by doing a performance)
- Have a way to communicate with the safety scubas below - it's been suggested that code streamers on rings dropped to the bottom like a tag to indicate 'wait 5 minutes', 'event cancel', 'emergency! bring up rig' etc.
I'm sure others have ideas popping up already as we have time to reflect on this. These two above were tossed about soon after the event.
Interestingly, half a dozen of us who were present know what a counterbalance is, how they are designed and constructed, and seen them in action (I have built a rig of my own) but were unfortunately not able to foresee this incident, so there's the pressure of the event to consider (the organizers were operating on less and less sleep as the event progressed). I believe there's a learning curve even if you know the stuff inside and out. So any system must have multiple safety cushions so not one event can cause harm to a competitor.
The competitors including myself probably could have continued and completed the event, but the organizers wisely cancelled it at the first signs of trouble. THAT's the hardest call to make and I'm glad to see Grant's years of tech diving experience played a role in this.
