| Certifications | Welding certifications (e.g., AWS, ASME) | Commercial diving certifications, underwater welding certifications |
| Work Environment | On oil rigs, ships, or offshore platforms above water | Underwater, often in deep or challenging water conditions |
| Industry Usage | Oil & gas, shipbuilding, offshore construction | Oil & gas, ship repair, underwater infrastructure |
Offshore Welding involves welding on structures above water, typically on oil rigs or platforms, requiring standard welding certifications. Underwater Welding, on the other hand, is performed beneath the water surface, demanding specialized diving and underwater welding certifications. Both roles are vital in the offshore industry but differ significantly in environment and certification requirements.
