Narrative
On june 5, 2020 at 12:30, a magellan contractor working in the watertown facility smelled a petroleum odor and notified local operations personnel. Upon investigation, magellan employees observed product leaking from a failed dresser coupler joint harness. The area was immediately isolated and cleanup activities were initiated. A valve on one side of the pipe section had been removed the previous day to isolate the tank for inspection, leaving the weight of the pipe supported by only the dresser coupler joint harness. The weight of the pipe caused the welds holding the joint harness to the pipe to fail. Localized corrosion was also noted at the weld and could have contributed to weakening of the welds.
