$70,000Benefits:
A significant reduction in the cost of structural repairs to U.S. Navy ships is anticipated if doubler plates are used as permanent repairs. Avoidance of drydocking for structural repairs can save several hundred thousand dollars per repair. If there were only one such instance per year, the U.S. Navy would save several million dollars over a 10 year period, quickly amortizing the investment in this research. Commercial structural design standards such as those contained in the classification societies would benefit as new performance data of doubler plates is incorporated. This would lead to better monitoring & inspection procedures for these repairs as well as provide a more cost-effective strategy for decisions to permanently repair doubler plates.
