THE INITIAL REPORT WAS RECEIVED MARCH 8, 2010 AT 10:00 AM CST. TGP BEGAN TRYING TO LOCATE THE LEAK BUT ISOLATED THE SUSPECTED 20\" 509A-1100 PIPELINE EVEN THOUGH A LEAK WAS NOT CONFIRMED. THE LEAK WAS EXTREMELY SMALL WITH THE PIPELINE LOSING APPX. 10 PSI PER DAY. ON MARCH 12, 2010 A LEAK WAS LOCATED IN CLOSE PROXIMITY TO A SUBSEA CONNECTION AND A MAINTENANCE (TIGHTNESS TYPE) LEAK WAS SUSPECTED. SEVERAL ATTEMPTS WERE MADE TO DIVE ON THE LOCATION WITH ULTIMALTE SUCCESS TO REPAIR IT BY APRIL 19, 2010. A PIN HOLE IN THE 6:00 POSITION WAS IDENTIFIED VERY CLOSE TO THE SUBSEA CONNECTION MOST LIKELY CAUSED BY INTERNAL CORROSION. PROBLEMS ENCOUNTERED IN ATTEMPTING TO MAKE A SUCCESSFUL DIVE INCLUDED INCLEMENT WEATHER AND DIFFICULTY IN OBTAINING PRODUCER PLATFORM BOARDING AGREEMENTS.\n\nPHMSA trend classification: significant incident, not serious.\n\nPHMSA standardized cause: CORROSION — INTERNAL.\n\nPHMSA indexed costs: $294,760 reported total cost, $163,467.833 in 1984 dollars, $383,818.117 in current-year dollars.\n\nPHMSA trend flags, standardized causes, and indexed costs are analytical fields added to operator-reported incident data. They do not represent final agency causal findings.","truncated":false,"body_characters":1849}
