(A -F) SECTIONS OF THE REPORT FROM 01/10/15 - 01/14/15. LISTED BELOW IS THE SUMMARY OF EVENTS: 12.14.14, OUR EMPLOYEES NOTED A SMALL SHEEN AND BUBBLES. GIVEN ITS PROXIMITY TO A PRODUCER SATELLITE FACILITY WE BELIEVED IT TO BE THEIR ISSUE, HOWEVER UPON HAVING THE COORDINATES PLOTTED OUT IT LOOKED TO BE ON OUR 26\" LINE. WE STARTED THE PROCESS OF ISOLATING THE SEGMENT BETWEEN SMI 33 AND VR 149 WHILE WE SOURCED A DSV TO INVESTIGATE FOR US. WE SPOKE TO THE USCG THE PREVIOUS EVENING ABOUT THIS AND JUST UPDATED THEM, AS WELL AS NOTIFYING THE NRC. 12.15.14, OUR FLIGHT REPORTED THAT THE LEAK AND ASSOCIATED SHEEN WERE AS PREVIOUSLY REPORTED WITH NO APPRECIABLE CHANGE. WE CONTINUED TO DISCUSS OPTIONS WITH DSV PROVIDERS. PRESSURE MONITORING WAS ONGOING WITH LITTLE DEVIATION NOTED. THE USCG WAS UPDATED AS TO STATUS. 12.16.14, WE LOCATED A DSV. THE SHEEN WAS STILL PRESENT BUT ONLY 1/4 MILE LONG AND WAS ENCOUNTERING A CHANGING CURRENT AND CHOPPY SEAS. WE GAVE THE USCG THEIR DAILY UPDATE. 12.17.14, THE DSV MADE IT TO THE SITE. INITIAL REPORT WAS THAT THEY LOCATED THE LEAK SOURCE VIA PROBE WITH APPROXIMATELY 5 FEET OF COVER. THEY CONFIRMED THE PIPE SIZE AS OUR 26'. THERE WAS NO REPORTED CHANGE TO THE LEAK ITSELF AT THE TIME. 12.18.14, OVERNIGHT WE WERE ABLE TO LOWER THE LINE PRESSURE AND BEGAN REMOVING CONCRETE AND MASTIC IN THE EARLY HOURS. IT APPEARED AT THE TIME TO BE A PIN HOLE LEAK. DIVERS CONTINUED TO CLEAN UP THE AREA TO OBTAIN THE VARIOUS UT AND CP READINGS NEEDED. 12.19.14, WE COMPLETED ALL PREP WORK ON THE PIPELINE AND CONFIRMED THAT A LEAK CLAMP WOULD BE OUR REPAIR METHOD. DUE TO THE INCREASING SEAS AND THE RISK OF A VESSEL TO VESSEL TRANSFER OF THE CLAMP, THE DSV WENT TO DOCK TO PICK UP THE CLAMP AND EQUIPMENT. 12.21.14, THE CLAMP WAS INSTALLED AND ALL LEAK CHECKS WENT WELL. WE WERE UNABLE TO FLY TO ALLOW PRODUCERS BACK ON AND RETURN THE LINE TO NORMAL SERVICE DUE TO WEATHER. 12.22.14, WEATHER FINALLY CLEARED UP. WE MADE AN OVER FLIGHT TO THE SMI 33 FACILITY, SEEING NO SIGNS OF LEAKAGE WHILE IN ROUTE. THE SMI 33 FACILITY WAS THEN PLACED INTO NORMAL SERVICE. THE HELICOPTER MADE STOPS AT THE LOCKED PRODUCER FACILITIES AND PLACED THEM IN NORMAL OPERATIONS.\n\nPHMSA trend classification: significant incident, not serious.\n\nPHMSA standardized cause: CORROSION — INTERNAL.\n\nPHMSA indexed costs: $455,696 reported total cost, $266,383.348 in 1984 dollars, $493,122.592 in current-year dollars.\n\nPHMSA trend flags, standardized causes, and indexed costs are analytical fields added to operator-reported incident data.
