The present economic climate is focusing downstream Oil Companies to maximize the use of their production assets. The major push forward has been the reduction in maintenance period with the emphasis on increasing activities which can be carried out when the plant is on stream. Inspection on stream has many advantages for the operator, the more obvious being that there is no requirement to shut their plant down. Other gains to be made are that there can be a better planning for any subsequent remedial action before a planned shutdown. This paper will discuss the progress made by Sonovation into the application of conventional and Automated Ultrasonic Techniques leading to the present capability of inspection at 900 degrees Fahrenheit (480°C). Explanations will be given on how this was achieved with the attendant considerations on Health and Safety, application problems with the required calculations. In addition several case studies will be presented.
