Frequently Asked Questions

Underwater welding can typically be performed at depths of up to 300 meters (around 984 feet), but the most common depths range from 10 to 50 meters (33 to 164 feet). The feasibility of deep underwater welding depends on factors such as diver experience, equipment, water pressure, and safety considerations. Advanced remotely operated underwater welding systems can extend the depth capabilities beyond human divers, reaching depths of over 600 meters (approximately 1,970 feet) in some specialized cases.

contracts generally range from 6 weeks to several months, depending on the project's complexity and scope, some contracts for large projects may extend up to a year to ensure all jobs and related tasks are completed efficiently and safely.

Dry hyperbaric welding in a habitat enables welds of comparable quality to surface welding when performed under qualified procedures and followed by proper NDT. Wet welding generally produces lower-quality welds and is used for temporary or non-critical repairs.

Typical mobilization time depends on location and equipment availability. For planned jobs allowing pre-mobilization, 2–6 weeks is common. For emergency response, we maintain rapid mobilization options; contact our emergency hotline for immediate dispatch.

Our personnel hold commercial diving qualifications, welding certifications and NDT qualifications compliant with client and industry standards. All certifications are internationally recognized and regularly updated. Exact certifications will be provided with project proposals.

Yes, we maintain 24/7 emergency response capabilities worldwide. Our emergency hotline is staffed around the clock, and we have pre-positioned equipment and qualified personnel ready for rapid deployment to critical incidents anywhere in the world.

Hyperbaric welding, also known as dry underwater welding or habitat welding, is performed in a sealed chamber around the weld area. The chamber is pressurized to match the water depth and kept dry, allowing welders to use conventional welding processes. This method produces high-quality, code-compliant welds comparable to surface welding.

Wet welding is suitable for temporary repairs, emergency stabilization, and non-critical applications in shallow water (typically up to 30m). It's faster and more cost-effective than hyperbaric welding but produces lower-quality welds. Wet welding is often used for emergency leak sealing, temporary patches, and situations where immediate action is required.

We utilize comprehensive non-destructive testing (NDT) methods including Ultrasonic Testing (UT), Magnetic Particle Inspection (MPI), Dye Penetrant Testing (PT), visual inspection with underwater cameras, thickness surveys, and corrosion mapping. All inspections are performed by certified technicians and documented with detailed reports.

Saturation diving is used for deep water operations or projects requiring extended bottom time. Divers live in a pressurized chamber and are transported to the work site in a diving bell, eliminating the need for repeated decompressions. This method is ideal for complex installations, deepwater repairs, and long-duration maintenance campaigns at depths beyond 50 meters.
