Why welding matters
Underwater welding is essential for the maintenance and repair of ships, rigs, and pipelines. By addressing critical issues below the waterline, it ensures operational efficiency, safety, and structural reliability for ships and offshore rigs.
Key benefits of underwater welding services:
Class-approved welding
Our underwater welders are certified to AWS D3.6M:2017 and ISO 15618-1:2016 standards, approved by Lloyd’s Register and DNV-GL. This ensures welds meet the strictest requirements for quality and structural integrity.
Reliable repairs in challenging conditions
From wet welding in emergencies to hyperbaric welding for precise repairs, our expertise allows us to perform maintenance and repairs under extreme underwater conditions.
Cost-efficient solutions
Underwater welding eliminates the need for dry-docking by enabling repairs and maintenance to be carried out on-site, reducing downtime and costs.

Hyperbaric welding
Hyperbaric welding is performed under elevated pressures and is ideal for repairs in wet and dry environments, including:
- Repair and maintenance of pipelines.
- Structural repairs for ships and offshore rigs.
- Repairs caused by hydrogen embrittlement.
Wet welding
For emergency repairs or challenging locations, wet welding is sometimes the only viable solution. Our underwater welders are highly trained to counteract the risks of wet welding, including rapid cooling and cracking. Techniques include:
- Shielded metal arc welding (SMAW)
- Flux-cored arc welding (FCAW)
- Friction welding (FW)
Fillet welding
We have class-approved welding procedures for fillet welds in all positions, ensuring reliable and safe repairs. Approved procedures for butt welds are pending.
Our experience
Since 2015 we have kept track of the tasks carried out within ships. We have furthermore done the same within rigs as of 2016. Our commercial divers have been part of carrying out these various tasks.
