Depending on the client, the work could consist of inspecting the internal or external surfaces of tanks, piping or pressure vessel. The inspections could be visual, ultrasonic thickness or other methods as needed. Any photos would be taken and the reports written and turned over to the client. Oddly enough the hardest part of the job was sometimes finding the jobsite due to the remote locations. For me the best part of the job, the inspection, is literallly performing the inspection to ensure the equipment is safe to continue using.
