What are the key inspection points when examining the structural integrity of a WEC?

When examining the structural integrity of a Wave Energy Converter (WEC), several key inspection points must be considered. First, welds and joints are critical areas, as they are often subject to high stress concentrations. Inspections should focus on detecting cracks, corrosion, and any signs of fatigue. Second, areas around hatches, access points, and other cutouts are also prone to stress concentrations and should be carefully inspected for cracks and deformations. Third, the mooring system, including the mooring lines, anchors, and connection points to the WEC structure, is crucial for maintaining the WEC's position and stability. These components should be inspected for wear, corrosion, and damage. Fourth, the hull or floating structure should be inspected for corrosion, marine growth, and any signs of impact damage. Pay close attention to areas below the waterline, as these are more susceptible to corrosion and marine fouling. Fifth, moving parts, such as hinges, joints, and bearings, should be inspected for wear, corrosion, and proper lubrication. Sixth, internal structural members, such as frames and bulkheads, should be inspected for corrosion, buckling, and any signs of damage. Seventh, components made of composite materials, such as blades or pontoons, should be inspected for delamination, cracks, and other signs of damage. Finally, areas that are difficult to access or inspect visually should be inspected using non-destructive testing (NDT) methods, such as ultrasonic testing, radiography, or dye penetrant testing.
