AIRLANT tasked Seaward Marine Services to complete underwater hull cleaning and Lamp Ray hull survey on the USS EISENHOWER (CVN-69) before her scheduled docking planned incremental availability (DPIA) at Norfolk Naval Shipyard. This effort consisted of divers cleaning the underwater hull using SCAMP, cleaning of the propellers and running-gear, cleaning of all seachest openings and shaft stave bearing clearance readings with video. The Lamp Ray hull survey is performed by a hull crawling ROV with acoustic tracking systems. The Lamp Ray platform reads plate thickness, coating thickness, and cathodic potential while sending video with laser dimensional gauging. All work was completed within a 15 day period. 

The CVN-69 Maintenance Program Manager passed along the following comment to Project Manager Dean Womack 

“Dean, please convey to your team what a phenomenal job they performed on the hull cleaning of CVN 69. The condition of the hull in the dry dock has received uniform praise from everyone who has inspected it. Your efforts will greatly facilitate the preservation that will be performed during this availability.”

Seaward would also like to thank the divers, supervisors, technicians, and support personnel who helped in the completion of this effort.
