Military Sealift Command Uses Seaward For Cleaning and Inspection on USNS Yuma

Posted July 25, 2018
Written by Cecil C. Achord

Seaward Divers were tasked to inspect the underwater hull of USNS YUMA (T-EPF-8) including impellers, stators, water jets, shafts, sea chests, fathometer/speed log, and appendages.  Divers cleaned the shafts, impellors and approximately 300 sqft of underwater hull in and around the water jet tunnels as directed by the on-scene representative and provided video and digital sill photos to document the hull condition.  Divers located possible discontinuities in the water jet and completed an underwater magnetic particle test to make the determination that they were not cracks but weld inclusion.  Divers completed all work within the period of performance and complied with all requirements established by COMCINST Engineering Operations and Maintenance Manual.  Diving Operations were carried out June 27-28 by Seaward Mobile 4.
