India - Oil and Gas - Petroleum Ministry says negligence caused fire at GAIL pipeline (June 2014 incident) in Andhra Pradesh

NEW DELHI: The Petroleum Ministry has blamed negligence for causing the devastating fire at state-owned gas transporter GAILBSE -1.59 % India Ltd's gas pipeline in Andhra Pradesh that killed 22 people.

An inquiry committee, headed by Joint Secretary (Refineries) Rajesh Kumar Singh, in a report submitted last week concluded that negligence caused the fire at the Tatipaka-Kondapalli pipeline on June 27.

Sources said the committee found that the pipeline had corroded due to condensate and water that came along with the natural gas from an Oil and Natural Gas Corp (ONGC) field.

Water corroded bottom of the pipeline, causing pores in the underground pipeline. Gas was being transported at high pressure and it leaked along with flammable condensate leaked out to the surface on the night of June 26/27. Overcast weather lead to a cloud of gas being formed even as condensate sprayed on the ground.

A spark, possibly from a cigarette or bidi lit by a local, at 0545 hours on June 27 led to condensate and cloud of gas catching fire with a loud explosion.

The other source of the massive fire is being mentioned as a tea vendor lighting up a stove in the vicinity of the leak, scorching everything in a radius of about half a km, including houses and vehicles, in Nagaram village of East Godavari district.

The exact source may not known as everything including the persons were charred, sources said.

Sources said gas should have been stripped of waste and condensate at GAIL's Nagaram facility before being pumped into the pipeline for transportation to a power plant.

  1. It should not be the blaming culture when integrity of assets is dealt by multi-owners who are involved in the entire value chain. Before process fluid gets transported through any asset, corrosion risk assessment has to be compulsorily carried out to determine the adequacy of transmission system to handle the fluids of varied composition and operating conditions. It is very difficult to ascertain the time of whole upsets in any process system. Not all parameters can be analysed in real time to trigger the range of actions needed to bring it to normal state. Our oil and gas companies have to improve the present status of their corrosion management and assure the integrity of assets. Replacement of pipeline after defined period is not the only solution for this type of failure. There is no point in identifying quick fix for corrosion issues. We need to learn from the failures as well as successful operation regime to bring the design values for new systems.
