The USS Yorktown is a seventy-two-year-old decommissioned Essex-class aircraft carrier berthed at the Patriots Point Naval & Maritime Museum in Mount Pleasant, South Carolina. Patriots Point Development Authority (PPDA) needed a comprehensive structural evaluation of the Yorktown completed in a short amount of time.
PPDA selected Collins to provide the evaluation. Collins’ assessment from February to November of 2014 included the exterior hull above and below the mud line using engineer-divers, the interior hull, all accessible interior compartments, estimation of corrosion rates and monitoring, recommendations for repairs, and cost estimates. The final deliverable was a clear and concise summary of the condition of the vessel’s exterior hull, 2,000 interior compartments, a cost estimate for each space, and a cost estimate for the overall repair project.
