| Industry Usage | Oil and gas extraction, offshore construction | Subsea repairs, pipeline installation, subsea infrastructure |
Flexible Offshore Oil Rig Welding involves welding on above-water structures on oil rigs and platforms, requiring standard welding certifications. Underwater Offshore Welding takes place beneath the water surface, requiring specialized diving and underwater welding certifications. Both roles are vital in offshore oil and gas operations but differ mainly in environment and certification requirements.
