Dry Welding with All-Sea Exclusive Underwater Habitat

Permanent CLASS APPROVED underwater weld repairs were thought to be IMPOSSIBLE until Subsea Global Solutions pioneered the certification process. Class approved permanent repair processes are established using underwater wet welding, atmospheric dry welding or hyperbaric dry welding for permanent repairs to incidental hull damage below water line. With an in-house Engineering department including Weld Engineers and Structural Engineers a repair procedure detailing the process of repair to be employed is develop upfront for pre-approval by insurance underwriters or Classification Societies. Subsea Global Solutions ensures a permanent repair is achieved on time where ever or whenever required.
