PORTSMOUTH, Va. (NNS) -- Nimitz-class aircraft carrier USS George H.W. Bush (CVN 77) arrived at Norfolk Naval Shipyard (NNSY), Feb. 21, for a 28-month dry-docking planned incremental availability (DPIA).

Dry-docking and maintaining a 103,000 ton, 1,092-foot aircraft carrier is complex work. This DPIA marks the first time George H.W. Bush has not been waterborne since 2006. Requiring an estimated 1.3 million man-days, it will be the most extensive maintenance period for the ship yet and one of the most complex CVN chief of naval operations availabilities in recent NNSY history. 

The shipyard workforce will be providing approximately 775,000 man-days, with ship’s force, alteration installation teams and contractor work comprising the rest. 

George H.W. Bush Project Superintendent Jeff Burchett worked to incorporate corporate lessons learned after visiting Puget Sound Naval Shipyard to see USS Nimitz (CVN 68) undergo similar work during its availability.

“There are a lot of first-time jobs all around, given this is the first time Bush has sat on keel blocks since being built,” said Burchett.  “With the size of this work package, it will take a total team effort by Norfolk Naval Shipyard.”

George H.W. Bush will fully tap into the 21st century tool kit with the goals to achieve first-time quality and ensure safety. Project team members will use advanced technology such as exoskeleton suits, additive manufacturing, laser scanners to create virtual rigging paths, and the development of training models using virtual reality. Burchett said the project team also engaged with NNSY engineering and the production shops to discuss ways to leverage innovations during the DPIA. 

With much of the project team performing work on a dry-docked carrier for the first time, Burchett said this is a prime opportunity to demonstrate the shipyard organizational values of Care, Ownership, Respect and Excellence (C.O.R.E.) across all working levels throughout the availability.

“We have new supervisors, new zone managers, new assistant project superintendents,” he said. “This is a great chance for teaching and mentoring people in new positions how to execute and perform to their top potential.” 

“As project superintendent, the safety and well-being of my team is the top priority - that goes for the shipyard, crew and contractors,” he added. “My relationship with the captain is strong, being focused on the mission and implementing C.O.R.E. with the ship.”

As the first carrier docking at NNSY in several years, George H.W. Bush will be on blocks for the majority of its availability. Naval Facilities Engineering Command (NAVFAC) helped get the dry dock ready for NNSY, with recent dock flooding and saltwater system upgrades to accommodate the ship. 

Following extensive planning during the past 18 months, and with an energized workforce leveraging state-of-the-art technology, Burchett is ready to get started.

“Our project team is poised and ready to take on this mission,” he said.  “There’s a quote from George H.W. Bush himself that we have taken on as the project team motto: ‘This is my mission and I will complete it.’”
