checking them, I would not have met the specified code requirements. At this point, I realized I was in a serious self-check moment and I needed to set aside all that I thought I knew and treat this job as if I was performing an exam for the first time. In other words, we verified every inspection requirement through the specification, and applicable code and procedure. Throughout the verification process multiple questions arose. After several conversations with the designer, project engineer, and other experienced inspectors, we obtained the required equipment and updated personnel certifications through additional testing. In addition, we made time available to gather specific information about the welds, including actual weld prep contours of the unique joints. Through this process, we were able to model the ultrasonic sound paths for coverage determination and understand the geometric reflectors expected. When the time came to do the actual inspections, we felt well prepared and ready to perform the work. While the inspections did not go off without some hitches, we were not shocked or surprised by what was identified throughout the inspection process. Lessons Learned What did I learn through this and similar experiences? 1. Challenge assumptions and respect others who challenge your assumptions even if they appear less experienced or qualified. 2. Don’t be afraid to ask a question, even if you are the one expected to know the answer. 3. Just because it is “the way we have always done it” does not make it right or mean the method cannot be improved upon. 4. Be patient; approach issues from different angles. You’ll find things do not always look the same when you observe it from a different viewpoint. 5. Thorough preparation is the best path toward speedy inspection. The bottom line is there is no such thing as a routine inspection in our business. Procedures are revised, codes and standards are updated, and equipment capability evolves. Inspection capabilities are improving every day. Ask yourself the question, “Am I keeping up or am I living in the past?” CHRIS T.
