Making use of the latest technology, such as digital radiography can result in considerable savings for the user in time as well as consumable costs and also enhance the probability of detection of defects. Automated ultrasonic testing that utilizes TOFD and phased array produces recordable results and a permanent record, which can be evaluated by third party inspectors at a later stage. Mostly importantly, this tangible benefit translates into a reduction of operator error and substantial time saving, which is derived from the high testing speed. Long range ultrasonic testing is a good screening tool for surface or insulated pipelines and will reveal suspect areas for further evaluation by other methods. An ideal example for what a great money saver this method is the testing of pipe crossings underneath roads and other short pipe lengths on pipe sleepers which are unable to be pigged or the use of pigs would be consider an overkill due to the associated costs. Intelligent pigging is extensively used for the evaluation of corrosion in pipelines and can be used on all pipelines fitted with pig launching facilities. Three dimensional laser beam profile measurement of corrosion is an extremely accurate tool for the measurement of the corrosion depth and location, finite element analysis and on site report generation allowing qualified engineering decisions to be made. Use of the above methods assisted in the development of risk assessment strategies and pipeline integrity management programs.
