As an underwater welder, one of the most common questions I get is, “How long do you stay underwater?” The answer isn’t as simple as a fixed number because it depends on a lot of factors. Let me share my experience so you can get a better idea.
It Depends on the Job
The time I spend underwater mostly depends on what I’m working on. If it’s a small repair, like patching up a crack on a ship or fixing a pipeline, I might only stay underwater for about 30 minutes to an hour.
But when I’m working on something bigger, like welding a part of an oil rig, I’ve spent up to 6 hours in one dive. For jobs like this, you need a lot of focus and stamina.
The Depth Makes a Difference
Depth is another big factor. When I’m working in shallow water, I can stay longer because the pressure isn’t as intense. But deeper dives are a whole different game. At 100 feet or more, the water pressure is so high that we have to be extra careful with our time.
In deeper waters, I’ve worked for about 3 to 4 hours before needing to resurface. And trust me, your body feels every bit of that pressure by the time you come back up.
Safety Always Comes First
Safety is non-negotiable in this job. We have strict dive schedules, and I always keep an eye on my oxygen levels. I use a surface-supplied air system most of the time, which lets me work longer without worrying about running out of air.
After every dive, we take breaks to let our bodies adjust to surface pressure. These decompression stops are critical to avoid health risks like “the bends.” It’s not something you can ignore if you want a long career in this field.
The Challenges We Face
Underwater welding isn’t just physically demanding; it’s mentally tough too. Visibility is often poor, and working in cold water can be exhausting. There are times when I can barely see the tools in my hands, let alone the structure I’m working on.
And let’s not forget the risks. Handling heavy tools and dealing with electrical equipment underwater comes with its share of dangers. But with proper training and experience, these challenges become part of the job.

My Personal Review
Being an underwater welder isn’t easy, but I love it. There’s something incredible about working in an environment that most people never experience. The challenges are real, but so is the sense of accomplishment when you finish a tough job.
For anyone thinking about this career, my advice is to focus on training, stay disciplined, and always prioritize safety. It’s not just a job; it’s a lifestyle. And while the time we spend underwater might vary, the passion for what we do stays constant.
