Abstract

The Coast Guard is responsible for the safety of thousands of vessels which carry passengers and cargo throughout the US. The Research and Development Center has had several projects with the objective of identifying advanced technologies that can increase the safety and efficiency of vessel inspections, especially structural surveys. The aim is to find technologies which will increase inspection coverage while still providing a complete and accurate condition of the vessel. One project focused on the basic technology items such as improved lighting, improved monitors to determine air quality, and use of visual enhancements such as binoculars and night-vision equipment which the inspectors could use directly. It continued on to more advanced nondestructive and visual methodologies which may not find the actual damage, but will indicate the most likely location to the inspector. These included magnetic climbers, robotics, advanced video camera systems and fiber- optic videoscopes, laser ultrasonics and climbing inspectors which utilize mountaineering techniques. Most of these advanced methods are more likely to be used by independent surveyors, classification societies or others hired by the vessel owners and operators. The Coast Guard needs to evaluate the effectiveness of these techniques to ensure the reliability of the information received and to bring some of the technology to the attention of owners and operators. Another project begun this year is investigating the nondestructive evaluation of metal fasteners in wooden boats. This paper provides an overview of these projects.
