Underwater Dry Welding


Certified welder drivers are employed to perform structural welds to Class inside dry habitats which are designed and built to fit around damaged areas. Welding quality is confirmed by NDT and certified by Third Parties. All welding works adhere to AWS D1.1:2006 Steel Structural Welding code.

Air is used to purge water from the habitat in welding applications to water depth of 20 metres. Beyond this depth, inert gases is used.

Besides crack repairs, Underwater Dry Welding can be used to weld sleeves, stiffeners and replacement members.


IEV and CUBIC Service Limited entered into a co-operation agreement to bring cost effective, safe and proven underwater welding technology to operators of oil and gas platforms in the Asia Pacific region.

The Underwater Dry Welding service is an integral technology in IEV’s Integrated Engineering solutions which address the challenges of subsea repairs and strengthening needs for existing and ageing offshore structures.
