Offshore Structural Welding involves welding on above-water structures like oil rigs and platforms, requiring certifications like AWS D1.1 and safety training. Underwater Structural Welding is performed beneath the water surface, often requiring hyperbaric welding certifications and diver training. Both roles are vital in the oil and gas industry but differ mainly in environment and specialized skills needed.
