Underwater Facilities Inspection and Assessment at Deperming Facility U.S. Naval Station Norfolk, Virginia.
Abstract
Nondestructive ultrasonic testing and inspection of a sampling of piles in the piers which make up the Deperming Facility at the U.S. Naval Station, Norfolk, Virginia, was carried out. This inspection has shown that on an overall basis the piles are in good condition, however, evidence of both mechanical and biological deterioration was found. The objective of the underwater facility assessment was to assess the physical condition and repairability of the structural members supporting the Deperming Facility. After a Level I 'swim by' of the entire facility, a Level II inspection procedure was carried out to insure the acquisition of sufficiently detailed data related to the internal structural integrity of each pile inspected as to enable determination to be made of the overall bearing capacity and lateral stability of the pier. The data provided is sufficiently detailed to facilitate comparisons with subsequent periodic inspections for purposes of determining progressive deterioration with time.
