In addition to what everyone else says, the most common way to fix stuff deep underwater (That you can’t just pull up to the surface) is called saturation diving. Depending on the job, people will stay and live in pressurized compartments down there, for looong periods of time. Weeks, possibly months. They don’t go below 1,000 feet as often, but have gone as deep as 2,300 feet. Look up a youtube video on it, it’s neat.
