My deepest commercial dive in the last few months has been to 45 metres for 35 minutes on a salvage job off Ireland, raising a trawler. My first few minutes on the bottom where a complete mystery to me, I was supposed to be rigging a tugger line to pull a heavy steel strop under the bow. I had to come up the shotline and go back down again before I was any good. After the first dive I was ok and went on to do a few more dives and controlled the lift on a night dive.
A few days later we were lifting a second bigger trawler which was upside down in 35 metres and my longest dive was 90 minutes and I left surface at 1 am and came out of the pot at 4am. The diving went on around the clock as we had to roll the wreck over on the bottom before lifting it and the crane barge was costing €40,000 a day.
Just for the record 4 ex PDA students were involved on this job so it is possible to get deeper dives inshore but most of your work is inshore civils involving concrete and big nuts and bolts.
