Technical Diving Services

Technical diving services represent some of the most complex and specialized work performed in underwater environments. These tasks go beyond general inspection or maintenance and often require advanced tools, precise measurement, specialized procedures, or collaboration with engineering and environmental teams. At True Depth Diving, our technical services are designed to support complex industrial systems, high-risk environments, and projects that require exacting accuracy underwater.

Technical services include tasks such as underwater welding and burning, non-destructive testing (NDT), ultrasonic thickness testing, 3D mapping, sonar surveys, cathodic protection inspection, confined-space diving, structural assessments, specialized recovery operations, and scientific support diving. These projects demand divers who are not only comfortable in challenging environments but who have the expertise to handle tools, equipment, and procedures with precision.

Underwater welding and burning are among the most recognized technical skills. They require strict control of equipment, stable positioning, communication with surface support, and understanding of metallurgical behavior underwater. Divers may use welding to attach plates, repair cracks, reinforce structural components, or secure fixtures. Burning is used to remove damaged sections, cut through steel, or dismantle underwater components safely. These tasks often occur in strong currents, restricted spaces, or blackwater conditions.

Non-destructive testing (NDT) is another major technical service. NDT methods allow divers to assess the condition of structures without causing damage. Techniques include ultrasonic thickness measurements, magnetic particle testing, dye penetrant testing, and visual/tactile inspections performed with specialized tools. These assessments help identify corrosion, cracking, thinning, or structural weakness. Engineers and facility managers rely on this data for safety evaluations, maintenance planning, and regulatory compliance.

Technical diving also plays a significant role in supporting environmental and scientific projects. Divers may conduct water sampling, vegetation surveys, sediment analysis, species monitoring, or underwater mapping. These tasks often require precise methodology and detailed documentation.

Confined-space diving is another advanced technical service requiring specialized training. Divers may need to enter pipelines, culverts, intakes, valve chambers, industrial tanks, or partially enclosed systems. These environments require extensive safety planning, redundant air systems, continuous communication, and carefully controlled access. Hazards may include entrapment points, limited visibility, restricted movement, and atmospheric concerns.

Sonar and imaging work are increasingly important for underwater engineering. In conditions where visibility is zero, imaging sonar can help create outlines of objects or structures. Combined with diver measurements and tactile confirmation, sonar helps map areas that would otherwise be inaccessible.

Technical recovery operations require creativity and precision. Recovering heavy machinery, tools, or lost equipment requires rigging knowledge, lift bags, stabilization techniques, and careful balancing of buoyancy and load distribution.

Because technical diving often takes place in high-risk or specialized environments, safety planning is comprehensive. Divers must be trained in risk mitigation, gas monitoring, confinement awareness, surface-supplied communications, emergency retrieval, and site-specific procedures. At True Depth Diving, we emphasize continuous training and skill refinement to ensure our team remains proficient in the latest methods, technologies, and safety protocols.

Technical underwater work requires patience, discipline, and a commitment to accuracy. Whether supporting engineering studies, repairing industrial systems, conducting scientific assessments, or performing advanced welding and NDT tasks, our team takes pride in delivering clean, precise, and reliable results. We work closely with engineers, facility operators, and project managers to ensure every technical assignment is completed to the highest standard of professional practice.
