Measuring Maritime Paint Thickness under Water Using THz Cross-Correlation Spectroscopy

The shipping industry is a major contributor to global greenhouse gas (GHG) emissions, which why it important optimize every aspect of the efficiency ocean-going vessels. This includes antifouling paint that ensures hydrodynamic efficiency. Measuring thickness on top all other layers using THz cross-correlation spectroscopy (THz-CCS) underwater could enable vessel operators monitor state ship hulls and plan any vessel’s sailing route maintenance optimally. However, due high absorption water in domain, measuring through significant amount impossible, making removal method necessary. study shows how THz-CCS system can be packaged for measurements molded silicone contact seal. In combination with spectroscopic model data treatment, single layer retrieved underwater. paves way more advanced capable multilayer maritime underwater, will companies continuously layers’ thickness.
