A large multinational offshore drilling company was facing a major maintenance overhaul for a semi-submersible. The company reached out to Applied Ultrasonics for a solution to minimise hydrogen embrittlement cracking and to ensure optimum weld quality assurance was maintained on critical structures and weld joints.

Applied Ultrasonics’ Engineering Services group collaborated with the drilling company to develop 25 weld Procedure Qualification Records (PQRs).

After approval of the PQRs, Applied Ultrasonics deployed a team of certified weld inspectors and Esonix UIT operators and inspectors to the shipyard for application of UIT and Quality Assurance. Applied Ultrasonics’ team remained onsite for the entire duration of the 40-day maintenance overhaul.
