Hull Contamination Measurement

We propose to develop a system to identify hull surface contamination, such as lubricants and amines formed during the coating process, using a measurement technique that can be adapted to a ship construction environment. The method we propose is laser light scattering, specifically standoff Raman scattering, to provide a noncontact, high-speed, accurate method of checking for and chemically identifying surface contaminants, allowing focused treatment of contaminated areas and better use of paints and coatings. In our program we shall develop a portable standoff scanning spectrometer that is optimized for large area detection and provides a surface evaluation that includes a Raman spectroscopic signature for localization and chemical identification of the contaminating medium for proper remediation of the hull coating.
