What is Underwater Welding & Pile Repair?
Underwater welding restores structural steel without dry-docking the vessel or de-mobilising a jetty. The two methods are wet welding (direct underwater, lower cost, fit for non-critical sections) and dry hyperbaric welding (in a sealed habitat, class-quality welds for primary structural members). Pile repair combines welding with steel plate doublers, sleeves, jacket reinforcement and protective coatings.
When do you need Underwater Welding & Pile Repair?
- Vessel collision or impact damage — cracks, dents, plate tears below waterline
- Pile section loss — corrosion-driven thickness reduction approaching design minimum
- Weld defect rectification — failed inspection at a previous repair
- Jetty extension or modification — adding bracing, fenders or fittings
- Emergency leak stoppage — temporary welded patch ahead of permanent repair

Q2. Is the weld accepted by my class society?
Ans: Yes — we work to AWS D3.6M Class A (hyperbaric) and Class B (wet) standards, both accepted by ABS, BV, DNV, LR, NK and IRS for the appropriate applications.
Q3. How quickly can you mobilise?
Ans: For emergency repairs, we mobilise within 6 hours from our Beach Road base. Standard scopes are quoted within 2 hours.
