Dry Docks 10 & 11. Newport News, Virginia.

Newport News Shipbuilding initiated a Service Life Extension Program (SLEP) to extend the useful life of Dry Docks Nos. 10 and 11 for another twenty-five years to accommodate the refueling schedule of the Nimitz-class carrier fleet.

Dry Docks 10 & 11 were designed and built under an accelerated construction schedule as prototype temporary cellular sheet pile structures before US involvement in World War II. Today, these temporary structures still serve as mission-critical facilities, providing refueling operations for the U.S. Navy’s nuclear-powered Nimitz-class carrier fleet.   Newport News Shipbuilding initiated the Service Life Extension Program (SLEP) for these drydocks to extend their service lives another twenty-five years to accommodate the projected refueling schedule for the remainder of the carrier fleet. The WRA team performed an in-depth analysis and evaluation of the existing sheet pile structures, completed the design of the prototype  repairs for these aging structures, oversaw the comprehensive implementation of the repair details, and recommended on-going inspection and monitoring efforts  to enable the continued use of the facilities well into the 21st century.
