Colonna’s Shipyard has awarded Seaward Marine Services, LLC Norfolk, VA a firm fixed Purchase Order to provide a waterborne underwater hull cleaning and survey on USNS Grasp (T ARS-51). Period of performance was April 2-6, 2018 at Joint Forces Base Little Creek in Norfolk, VA. 
 

The underwater hull survey was completed using the Lamp Ray Remote Operated Survey Vehicle. Seaward's Lamp Ray® ROV is a portable underwater robotic hull scanner integrated with a topside data acquisition system and controller. It performs a comprehensive hull material condition survey using sensors for ultrasonic testing, dry film thickness, and cathodic potential. 

All work was completed on time and within the budget estimate.
