Energy infrastructure inspection
Introduction
An inspection is generally an organized examination or formal evaluation exercise. In engineering activities, inspection involves measurements, tests, and gauges applied to certain characteristics with respect to an object or activity. Results are typically compared to specific requirements and standards to determine whether the item or activity is in line with these objectives, often with a Standard Inspection Procedure implemented to ensure consistent verification. Inspections are usually non-destructive.
Inspections may be a visual inspection or involve detection technologies such as ultrasonic testing, performed with a direct physical presence or remotely, such as a remote visual inspection, and manually or automatically, such as an automated optical inspection. Photogrammetry and non-contact optical measurement have become common NDT methods for inspection of manufactured components and design optimization.
A review of public service scrutiny by the Scottish Government in 2007 (the Crerar Review) defined public service inspection as "... regular, targeted scrutiny of specific services, to check whether they meet national and local performance standards, as well as legislative and professional requirements, and the needs of service users."[1].
A surprise inspection tends to have different results than an announced inspection. Leaders who want to know how others in their organization are performing can drop by unannounced to see firsthand what's going on. If an inspection is reported in advance, it can give people the opportunity to cover up or correct errors. This could lead to distorted and inaccurate conclusions. Therefore, a surprise inspection gives inspectors a better idea of the typical condition of the inspected object or process than an announced inspection. It also improves external confidence in the inspection process.
Specific inspection
Manufacturing
Quality-related in-process inspection/verification is an essential part of quality control in manufacturing. characteristics of a product or process and comparing the results with specified requirements to determine whether the requirements for each characteristic are met.[3][4]Common examples of inspection by measurement or calibration include the use of a caliper or micrometer to determine whether a dimension of a manufactured part is within the dimensional tolerance specified on a drawing for that part and is therefore acceptable for use.
