Case 31                              Date: 08.07.2020                      Time: 15:30 hrs.


             Incident

            Furnace oil (FO) was leaking from pin hole developed in 10”line in pipe sleeper along Road-C. FO line was
            depressurized & foam blanketing was applied by F&S on the pool of HC. Pin hole in the line was clamped
            after line depressurization. Spilled HC was lifted through super sucker and unsafe condition was averted.

















                                                     Leak from 10 inch line


             Root Cause


           Pin hole leak from 6 O' clock position due to material defect.


             Recommendations

            1.   Sleeve welding of leaky portion.
            2.   Oil to be removed from the nearby area.

            3.   Water logging around the sleeper pipe area to be cleared.
