Unpopular opinion: getting my umbilical snagged at the BP Clair platform taught me more than any class ever did
About 3 years ago I was doing a sat dive off the BP Clair platform in the North Sea, about 75 meters down, when my umbilical got snagged on a piece of subsea junk that was not on any of the survey drawings. I was on the bottom doing a valve check when I felt the tug, and my surface comms started cutting in and out. The standby diver was in the water in under 2 minutes, which felt like an hour. What really got me was that the snag point was only about 4 meters from where I was working, so I had been swimming past it for 20 minutes without clocking it. Since that day I do my own mini survey first on every bottom job, no matter what the drawings say, just a slow lap around the work site before I touch anything. Cost me an extra 10 minutes a dive but it has saved my ass twice since then. Any of you do a self survey before you start work, or do you just trust what the dive plan says?
