“We also worked with [NNSY’s Process Improvement division] Code 100PI for a range of strategic planning meeting initiatives that enable us to be successful.

“These initiatives range from buying new eyebrows that improve the routing of services to reviewing existing requirements to see if they can be improved. We have also arranged a weekly cadence with the ship to make sure it is well prepared for the expectations and knowledge of the shipyard. ”

According to Naval Sea Systems Command, the Toledo will be on the pier for an “extended period” before heading to the dry dock, as the dry dock is currently undergoing maintenance to upgrade its caisson, flood wall and piping.
