About this file
This document is a Nondestructive and Visual Inspection Report for thickness measurements conducted on the R/V Okeanos Explorer vessel on November 5, 2020. The report details precise thickness measurements of the Lower Engine Room Deck's deck plating, systematically recording original thickness, maximum allowable diminution, and actual gauged measurements for 66 individual measurement points across port and starboard sides. The measurements reveal varying levels of material diminution, with most points showing between 0-30% thickness reduction, indicating ongoing structural assessment of the vessel's deck integrity for potential maintenance or repair considerations.
The report was prepared by VT Marine's Nondestructive & Visual Inspection, LLC, with technician Jonathan Rosales (ASNT II, ABS Certification No. 18-HOM-3583568-A) performing the measurements. A plan view diagram accompanies the data, color-coding areas of measurement with notations for "substantial wastage" (orange) and "excessive wastage" (red), which provides a visual representation of the deck's condition. The document is directly associated with NOAA's Okeanos Explorer vessel and appears to be supporting documentation for potential drydock repair planning, specifically linked to the federal contract opportunity solicitation number 1305M225Q0151 for FY26 Okeanos Explorer Drydock repairs.
