Abstract	The new R.A.D.A.R. (Riser Active Data Acquisition Recorder) program allows for full marine drilling riser inspection while the joints are stacked on the deck of the rig with no disassembly. With the utilization of ultrasonics, robotic tools have been developed to pass through the inside diameter of the main tube and auxiliary lines to obtain potentially thousands of pipe wall readings and to record the weld integrity of each weld. The tools are also capable of video recording the pipe interior. Trained inspectors complete the riser survey with dimensional, visual, and magnetic particle inspections on the end connections of the main tube and auxiliary lines. Inspection data is compiled and stored in a database and is added to previous inspections and will be utilized for trend analysis. Using statistical methods the inspection history can predict trends of riser life and the potential for future repairs. This will assist operators to predict riser repairs, out of service time, cost of repairs, and most importantly eliminate extremely costly rig down time. The RADAR program has successfully inspected over 110,00 feet of pipe since its inception in September 2001.
