Life Extension Techniques, Inspection and Maintenance of Renewable Energy Equipment
Published in Bella H. Chudnovsky, Transmission, Distribution, and Renewable Energy Generation Power Equipment, 2017
Gearbox inspection goal is to perform a general assessment of the gearbox’s condition. Inspection of the gearbox via a flexible video-endoscope on all visible bearings, cogs, pinions, and sprockets may reveal multiple defects. An example of damaged WT gearbox found with remote visual inspection [14] is shown in Figure 20.1. It was most likely caused by metal debris floating around in the gearbox/oil.
Applications

In lakes and ponds, feeding and harvesting fish is becoming robotized. In all such operations, it is essential to monitor the operations, which are done remotely using built-in sensors as well as means for periodic remote visual inspection by humans.
Automated Object Detection for Visual Inspection of Nuclear Reactor Cores

An important activity required for the continued safe operation of nuclear power plants is a detailed understanding of the condition of the reactor internals. Inspections carried out during routine planned periodic outages are a primary means of understanding the health of the reactor internals. The type and frequency of inspections vary between different countries and reactor designs, but the underlying approach is common. This approach is to gather appropriate and representative data on key components and manually evaluate and report the condition of these components for return to service of the plant. This evaluation tends to encompass the two related activities of detection of predefined indicators of health and the subsequent quantification of the severity of these indicators. Traditionally this evaluation is a manually intensive and laborious process undertaken by a domain specialist drawing upon years of operational experience. The types of inspection data usually gathered and interpreted are either videos and images from remote visual inspection (RVI) equipment, or where volumetric assessment is required, ultrasonic scans or similar.
An approach for evaluating tensile strength of painted steel plates from the surface rusting grade

A visual evaluation method for tensile structural performance of rusted steel structures is investigated in this study. The proposed approach or Table 5 is applicable to assist decision-making at visual inspection stage prior to in-depth inspection, as shown in Figure 12. From remote visual inspection, inspection engineers can easily determine percentage of rusted surface area using pictorial visual samples and rusting grade, and then they can determine whether the repainting should be required by referring to allowable rusting grade. Inspection engineers can also easily determine reduction range in tensile strength using Table 5 and they can determine whether the structural safety inspection should be required by referring to allowable tensile strength.
