Well bay configurations often attempt to place risers as close as possible without incurring interference. Often avoiding interference is not possible, or resulting spacings are impractical and uneconomical. Alternatively, attempts have been made to quantify the results of impacts incurred by risers in service. Collision tests and numerical analyses have been conducted on pipe-on-pipe collisions to help establish such design guidelines. Collected test data have been scanned to establish the design algorithms for strength assessments and fatigue damage predictions of riser systems. This paper illustrates the methodologies and procedures to obtain the desired information from the test results.
