Narrative
At approximately 3:50pm on 6/8/2010, lcpl control room was notified of a leak within the refinery that may involve the 16" line from lcr to lcpl. The line was immediately shut down and pipeline emplyees were dispatched to the refinery to investigate. The crew verified that the source of the leak was the lcpl 16" line and began cleanup efforts with help from the refinery. Conclusion: the cracking found in the lc-01 pipeline was caused by fatigue cracking. The cracking was found next to the fillet weld on the bottom of the pipeline that welded the end to the pipe line. Fatigue cracking in the pipeline resulted from cyclical stresses in the piping. The cyclical stresses could be caused from a number of sources such as starts from the pumps, flow vibration, thermal gradients, poor support, etc. The exact source of the stresses could not be determined and would require further analysis/examination of the piping system. Going forward cop will do a surge analysis and will adjust it's operating procedures accordingly for this system.
