Had a close call with a silt out in a Florida canal last week
We were doing a simple inspection on a canal gate near Miami, maybe 30 feet down. The bottom was just soft mud and the viz was okay, maybe 10 feet. I turned to check a weld and my fin must have hit the bottom just right, because the whole world went dark brown in about two seconds. Couldn't see my hand in front of my face. My umbilical line got tangled on some old rebar I hadn't seen. I froze for a second, which is the worst thing you can do. I just focused on my breathing, felt my way down the umbilical to the snag, and got it free. Told topside I was coming up on the line and did a slow, controlled ascent. It felt like forever but was probably only a minute. Anyone else have a simple job go sideways that fast from a silt cloud?
