Subsea Acoustics For Commercial Diving
Subsea Acoustics For Commercial Diving
(OP)
I work for an offshore construction company and would like to take a new safety measure in one of our common practices. Below is a brief description of the practice. I am not looking to invent/patent anything, I am looking for an already made product.
Currently, when laying pipelines, commercial divers check the line as it is being laid for proper execution. If there is a buckle/dent/kink/etc that can create an opening in the line, there is a pressure differential as the line is now being filled with water through the opening. We currently have safety precautions in place to avoid injury to the diver, but I would like to take this to the next level.
I am looking for an acoustic device, something handheld such as a transducer, that the diver can hold to the pipeline. If there is a leak in the line, the transducer will pick up the extra noise/vibration and relay it to the appropriate personnel to all-stop the diver and the pipelay.
The transducer cable will be married to the diver's umbilical and the transmitter will be with the diving supervisor.
Any thoughts?
Regards, Dan

Also there are some ultrasonic flow meters that have an audible output.

You might have more luck with an accelerometer, possibly with a magnetic base.

If you go to the Dolphin Ear site there are some sounds samples over a wide spectrum of frequencies. There software is free.
I don't think the listening and interpretation part is going to be any problem. The problem as I see it is to get the equipment hardened and rugged enough for divers to use without any added finesse.
