Caisson
EBDG leverages its expertise in caisson design and analysis to support critical infrastructure projects, providing robust solutions for water management and power generation facilities. Utilizing advanced finite element analysis (FEA), we assess and enhance caisson structural integrity, ensuring compliance with stringent regulatory standards. Our services include structural evaluations, repair planning, and operational support for installation and maintenance. EBDG's comprehensive approach ensures the safe and efficient performance of caisson assemblies, making us a trusted partner in the marine and energy sectors.
Rocky Reach Caisson Assessment
For Chelan County PUD, EBDG conducted a feasibility study on the Rocky Reach Dam caisson, constructed in the 1960s, and identified the need for structural upgrades. We developed a detailed repair plan and procedure for careening the caisson, ensuring its continued reliability and operational efficiency for spillway maintenance.
Avista Corporation Intake Caisson Loading Analysis
EBDG supported Avista Corporation by analyzing the structural and buoyancy characteristics of intake caisson assemblies at Nine-Mile Dam. Our work ensured the adequacy of the caisson structures for de-watering generator turbine intakes, providing step-by-step installation instructions to guarantee safe and effective maintenance operations.
