MOUNT PLESANT, SC (WCSC) - An engineering firm estimated it will cost about $40 million dollars to make repairs on the aging hull of the USS Yorktown.
Collins Engineering and Ocean Technical Services presented their structural report of the ship to the Patriots Point Development Authority's Board of Directors Friday morning.
"Thanks to this report we now have a detailed analysis of what needs to be done to repair our historic ship," Executive Director Mac Burdette said in a statement.
According to the report, the historic aircraft carrier's hull is in relatively great shape considering that it has spent more than 40 years resting in the salty waters of Charleston Harbor.
Though problem areas of the ship's hull pose no immediate risk, they "must be addressed in the foreseeable future," the report states.
"Our next step is to develop a specific plan to address these repairs and move forward in taking care of the ship perpetually for future generations to enjoy and learn from. Certainly a funding plan is an essential component in moving forward," Burdette said in a statement.
After studying more than 100 areas of the interior and exterior of the ship, engineers determined that as a whole, the steel hull has only lost an estimated five percent of its thickness, considered relatively low.
The highest rates of corrosion were found in the splash area of the ship just above the waterline and the forward 200 feet of the ship in the bow region.
Engineers recommended that the board continue to regularly inspect the hull while continuing to paint and coat exposed areas, the report states.
According to the Patriots Point website, the ship was commissioned on April 15, 1943 and participated in the Pacific Offensive in World War II. The ship also served during the Vietnam War and recovered Apollo 8 astronauts in 1968.
It was decommissioned in 1970 then towed to its permanent home at Patriots Point in 1975, the site states.
