Offshore Drilling Semi-Submersible Procedure Qualification and Lifecycle Optimization

Applied Ultrasonics was engaged by a large, multinational offshore drilling company to develop a solution to minimize hydrogen embrittlement cracking and to ensure optimum weld Quality Assurance during a major maintenance overhaul for a semi-submersible.

Applied Ultrasonics and the offshore drilling company worked hand in hand to develop 25 weld Procedure Qualification Records (PQRs) for the semi-submersible’s vital structures and weld joints.

Once the weld PQRs were approved by the client, a qualified team of certified weld inspectors and Esonix UIT operators were sent by Applied Ultrasonics to work onsite at the international shipyard. The Applied Ultrasonics team provided onsite guidance and application for the duration of the 40-day semi-submersible maintenance overhaul.
