Intake Crib Weld Repair: Reliable Underwater Welding Solutions
UCC was contracted to perform inspections on the raw water intake structures at a facility on the Great Lakes. Upon inspection, it was discovered that 75% of the structure cap and support members beneath the cap had collapsed over the winter, posing a significant risk to the facility’s water intake operations.
UCC was further contracted to perform structural repairs starting with the removal of the damaged areas while final repair drawings were being developed. Leveraging our expertise in intake crib weld repair services, we executed underwater welding and structural reinforcement to rebuild damaged sections. The work began by cutting the material using underwater cutting torches (BROCO) and a variety of pneumatic and hydraulic grinders.
After repair drawings were issued, UCC ordered the necessary materials per engineering requirements via a fabrication company that completed the fabricating prior to being loaded and shipped to the work location.
Step-By-Step Repair Processes
Once on site, UCC divers rigged and carefully craned each piece into place according to the project drawings. Throughout the installation process, they worked to ensure precise alignment and secure placement of all structural components.
When field modifications were required, UCC divers promptly identified the necessary adjustments and communicated them in detail to the project engineers. The engineering team then developed and approved the required changes, ensuring that all modifications met structural and safety standards before implementation. UCC’s ability to adapt in real time, combined with its expertise in underwater welding and intake crib weld repair services, ensured that the project remained on schedule and in compliance with all engineering specifications.
Certified Underwater Welding
The field modifications were done by qualified UCC personnel on site to alleviate any delays. All work was completed using UCC procedure qualified underwater and top side welders. Six (6) certified underwater welders were required for the project using AWS D3.6 and D1.1 all position groove welds with certified underwater welding electrode.
In addition, UCC provided two (2) certified level II underwater welding QC personnel to perform inspections and document the work being performed while the project was progressing. UCC’s welding and QC programs were reviewed and accepted by the customer. The project was completed under budget and with zero safety incidents.
