Narrative
On august 31, 2020 at 13:50, 4 gallons of gasoline were discovered near an excavation area where work was being performed inside the terminal. The source of the leak was identified as 130-3 tank line. The tank line was isolated by a valve upstream and a blind downstream and the product was cleaned up immediately. When the leak was discovered, the cost of repairs were estimated to be $17,000. After additional investigation, it was determined that the tank line would need to be replaced and on september 1, 2020 at 16:25, the cost of repair was estimated at being greater than $50,000. Metallurgical analysis results concluded that the there was weld cracking due to inadequate weld penetration. There was also a pin hole leak due to severe fit-up issues between the two sections of pipe that were joined by the girth weld and inadequate weld penetration. Plan for prevention: current welding procedures and inspection requirements should ensure this does not occur in the future.
