"This underlines the fact that further legislative regulation is needed to protect the pipeline and other essential infrastructure. "We also take pride in the Inquiry's findings around the high standard of the response of our staff and contractors to the pipeline rupture," he said.įuge acknowledged the inquiry's confirmation that the pipeline had been damaged by a digger that should not have been working over the pipeline and that the damage had not been reported. "Among its findings the inquiry concluded that Refining NZ maintained and operated the RAP properly and in keeping with all legal requirements and standard industry practice. The rupture exposed major holes in this infrastructure.įuge said the Refinery concurs with the inquiry's comments about current fuel storage at the Auckland end of the pipeline, especially the urgent need to build jet fuel resilience at Auckland airport. The report also called for a new National Fuel Emergency Plan, and for the Ministry of Business, Innovation and Employment to take a leadership role.Ĭurrent fuel supply chain infrastructure was largely owned or controlled by the three major fuel companies: BP, Mobil and Z Energy. Parts of the supply chain would not be able to meet basic demand in a few years' time, let alone recover from, or provide resilience, during any significant outage. When maximum internal pressure exceeds the burst pressure, the pipe will crack, leak, explode. after a pipeline about 12 inches in diameter leaked, according to a statement from Petrleos Mexicanos, or Pemex, Mexico’s state-owned oil monopoly. This means our vulnerability is increasing." Burst Pressure - Burst pressure is the maximum internal pressure that a pressurized component such as piping or joint or tube can withstand before rupture or burst. "There is limited storage near the airport to provide cover for an outage and the number of days of cover that storage provides is decreasing as the daily demand for jet fuel grows. "With only a single supply chain for jet fuel, a single point of failure at any point along that chain can cause a complete disruption of supply to Auckland Airport. The inquiry found Auckland's jet fuel supply was currently not sufficiently resilient.
This calculator and associated equations will determine the working pressure of a known diameter pipe. Oil pipeline break dumps crude on California beach.
The rupture stopped the transmission of fuels into Auckland for 10 days and airlines had to limit jet fuel to 30 per cent of their usual usage, which caused significant disruption to flights to and from Auckland.
