About this file
This document is a detailed ultrasonic thickness measurement report for the R/V OKEANOS EXPLORER research vessel, conducted by NVI, LLC on December 7, 2020. The comprehensive survey systematically measured the thickness of various structural components including side shell plating, deck plating, bottom plating, transverse frames, bulkheads, tank tops, and sea chest areas. The inspection was performed using an Olympus 38 DL Plus ultrasonic thickness gauge, with measurements taken across 66 different structural sections to assess metal diminution and potential corrosion.
The survey covered multiple vessel locations, measuring original and remaining thicknesses of metal components, with particular attention to suspect areas in ballast tanks, engine rooms, and various deck and hull sections. Significant findings include localized thickness reductions ranging from 0.3% to over 40% in some areas, with most measurements showing diminution between 1-15%. The report was certified by ABS (American Bureau of Shipping) and conducted by technician Jonathan Rosales, an ASNT Level II certified inspector, using standardized non-destructive testing techniques to evaluate the vessel's structural integrity.
