This thesis investigates three applications of OECT sensing in subsea environments. The first focuses on the development and optimization of an OECT for detecting crude oil pipeline leaks, demonstrating the stability of OECTs in synthetic seawater and their ability to rapidly detect crude oil even in the presence of other organics. The second explores the development and optimization of an OECT for detecting carbon dioxide leaks, emphasizing the potential of OECTs as gas sensors and examining the effects of surface charges on the OECT channel.
