At Depthforge Trident, welding and assembly are more than just fabrication tasks—they are the foundation of safe, durable, and mission-ready subsea structures. Whether operating onshore or 300 meters below the surface, our team ensures each weld is performed to exacting standards that meet global safety and engineering codes.
We specialize in underwater welding, pressure-rated assembly, and the construction of structural components for pipelines, ROV docking systems, subsea frames, and support infrastructure. With access to cutting-edge equipment and certified welding professionals, we ensure every joint, bracket, and bolt contributes to the overall performance and longevity of your asset.
Each project undergoes strict quality control and testing—from visual inspections to non-destructive examination (NDE)—so you can trust that your infrastructure will withstand the harshest marine environments. Whether it’s for offshore energy, marine construction, or naval operations, our welding and assembly services are built to perform and last.
Our welding techniques ensure strong, lasting joints that withstand extreme subsea conditions—guaranteeing reliability and safety for all underwater infrastructure and components.
Each assembly is executed with exacting detail, ensuring accurate alignment, fit, and performance, even in high-pressure, mission-critical subsea applications.
Our team includes highly trained, certified welders and technicians experienced in both dry and wet welding under industry and global safety standards.
We use corrosion-resistant materials and proven welding processes to build assemblies that maintain performance despite prolonged underwater exposure and extreme ocean conditions.
Every weld and assembly undergoes rigorous inspection and testing—including NDT—to ensure it meets required strength, alignment, and safety standards.
