Incident Narrative

TUESDAY, JULY 14, 2020 A LEAK WAS CALLED INTO OUR HOUMA OFFICE BY THE PRODUCER PLATFORM IN ST 229 A SHORT TIME AGO. OVERFLIGHT FOUND A 1 MILE BY 15 MILE SHEEN, RANGING FROM DARK BROWN AT THE SOURCE TO RAINBOW AND SILVER ON OUTER EDGES. WE HAVE CALLED THE NRC WITH CASE NUMBER 1281840 ASSIGNED AND ARE WORKING TO ISOLATE OUR LINE FROM THE REST OF THE SYSTEM, PRODUCTION IS GOING OFFLINE AT ST 229 AS WELL. WEDNESDAY, JULY 15, 2020 OVERFLIGHT THIS MORNING SHOWS THE BUBBLES TO BE REDUCED IN SIZE, WITH A SHEEN APPROXIMATELY 100 FEET BY 15 MILES THAT IS SILVER TO RAINBOW IN COLOR AND DISSIPATING. WE ANTICIPATE A DSV TO BE IN THE FIELD EITHER SATURDAY OR SUNDAY, WATER DEPTH HERE REQUIRES A SAT VESSEL AND THERE IS LIMITED AVAILABILITY. LINE PRESSURE IS DOWN TO 370 PSIG AND FALLING, WE PLAN TO TAKE IT TO BOTTOM PRESSURE AS IS OUR NORMAL. WE HAVE UPDATED THE USCG WITH TODAY'S FINDINGS AND OUR PATH FORWARD. AT THIS TIME WE STILL HAVE NOT CONFIRMED RESPONSIBILITY BUT INDICATIONS ARE THAT IT IS LIKELY OURS. FRIDAY, JULY 17, 2020 WEATHER HAS PREVENTED OVER FLIGHTS THE LAST TWO DAYS BUT THE PRODUCER PLATFORM IS REPORTING NO BUBBLES THIS MORNING WITH A GOLD TO RAINBOW COLORED SHEEN, 150 YDS. BY 2 MILES. WE WILL RESUME OVERFLIGHTS AS SOON AS WEATHER CONDITIONS ALLOW. THE LINE IS CURRENTLY AT APPROXIMATE BOTTOM PRESSURE AND WILL REMAIN SO. THE DIVE VESSEL HAS AN ETA TO THE SITE OF SUNDAY MORNING, THE REPAIR CLAMP WILL BE ONBOARD. WE HAVE BEEN IN DAILY CONTACT WITH THE USCG PROVIDING UPDATES. THE NRC AND USCG WILL BE UPDATED AGAIN TODAY WITH THE INFORMATION AND THAT ALL INDICATIONS ARE THE LEAK IS OUR LINE. MONDAY, JULY 20, 2020 THE LEAK HAS BEEN CONFIRMED AS BEING ON OUR 10 IN. LINE, AT THE 7 O'CLOCK POSITION. THERE HAS BEEN NO SHEEN PRESENT IN THE AREA SINCE THE MORNING OF 7/18. THE PROTECTIVE COATING HAS BEEN REMOVED FROM THE LINE AND THE UT INSPECTION PERFORMED.
