Abstract: Navigation structures such as miter gates and sluice gates are primarily made out of steel, which makes them highly susceptible to corrosion, pitting, and fatigue cracks after many years in service. To mitigate the corrosion issue, protective anti-corrosion epoxy coatings are applied to the steel surface before the structure goes into operation and following scheduled inspections if coating loss is detected. The inspection process is typically a costly and potentially dangerous endeavor due to the need to inspect submerged areas of the structure where structural and environmental conditions may be at their worst. Divers are often used when dewatering is too costly or not possible. This study was generated by the need to find a better solution to the navigational structure corrosion/coatings inspection process. Primary objectives of this endeavor are to improve inspection area coverage, reduce inspection subjectiveness, reduce time, reduce cost, and reduce risk to human life. To achieve these objectives, a sensor system was developed to collect corrosion data and anti-corrosion coating thickness data; the system was then integrated onto a semi-automated platform capable of traversing targeted inspection areas above and below the water surface. This platform is referred to as the Mobile Sensor Inspection Platform.
