NORFOLK, Va. - Norfolk Naval Shipyard (NNSY) welcomed the aircraft carrier USS Dwight D. Eisenhower (CVN 69) for its 14-month Drydocking Planned Incremental Availability (DPIA) Sept. 10.
The carrier's DPIA centers around modernization of its propulsion plant and repairs. The work package includes the removing and overhauling all shafting and rudders; blasting and painting of 100 tanks, voids and vent plenums; blasting and preserving the underwater hull and freeboard; and installing two new sponsons for the carrier's Close-In Weapons System.
"This will be NNSY's largest DPIA to date, sizing over a total of 850,000 mandays which includes NNSY, ship's force, contractors, and alteration installation teams," said Project Superintendent Brian Bennett. "NNSY's portion of this DPIA is 430,000 mandays."
The project will include shipyard employees from Puget Sound Naval Shipyard, who began a 16-month DPIA on USS John C. Stennis (CVN 74) in June.
"We're sending some of our folks to train and accomplish work on Stennis, and then bring that same team - both Puget and Norfolk [personnel] - back to Norfolk to accomplish that same critical path work on the Ike," said Bennett. "It's the One Shipyard Concept of smartly sharing resources."
The availability is also poised to benefit from the establishment of job readiness cells co-located in the ship's hangar bay, giving project mechanics easy access to tooling, material and consumables as needed. Bennett said a similar, previous effort during the 2012 availability on USS George H.W. Bush (CVN 77) showed improved efficiency for the supervisors and mechanics. As NNSY's last carrier availability, Bush finished two days early and under budget in December.
"Thanks to thorough preparation, effective resource sharing with Puget Sound Naval Shipyard, an excellent relationship with ship's force and a great project team, I'm confident we are positioning this to be the second consecutive successful carrier availability for the shipyard," said NNSY Commander, Capt. Mark Bridenstine.
NNSY, a field activity of the Naval Sea Systems Command specializes in repairing, overhauling and modernizing ships and submarines.
