It is good to note the change in integrity approach after the dreadful pipeline accident. When old infrastructure is replaced with new pipeline system, historical analysis needs to be incorporated in the LCC for proper design. There are many reasons for pipeline failures. Internal corrosion of pipelines is completely ignored by the asset owners. Installation of online analyzers to transmit the real time data for specific parameters is not the only measure for monitoring corrosion. It should be the combination of offline and online data collection of many parameters to track the performance of materials and corrosion control. We do not see the active recruitment of corrosion engineers by oil and gas companies in India to form the backbone of asset integrity. At the present time, a majority of corrosion management activities are handled by non-corrosion groups. There is a sizeable pool of Indian Corrosion Management professionals working in the overseas. Companies in India should open the doors for knowledge collaboration with these professionals to formulate our geography specific standards and develop the talent force.
NEW DELHI: GAIL, India's largest natural gas pipeline operator, will deploy drones to guard its pipelines, as part of a host of initiatives to raise safety standards that includes replacing old pipelines and integrating advanced technologies.
The move follows one of the worst accidents involving the firm in June last year when its pipeline carrying natural gas exploded in Andhra Pradesh, killing about two dozen people and bringing it harsh public criticism.
A government probe into the accident had highlighted safety lapses at the firm and prompted the regulator, Petroleum and Natural Gas Regulatory Board (PNGRB), to slap a penalty.
Officials said the company is looking to induce a new culture of safety in the organisation. "We are migrating from a reactive to a proactive management, from a breakdown maintenance culture to a predictive maintenance culture," Karnatak said.
It is installing online analysers to identify moisture and corrosive substance in the supply, a key reason leading to last year mishap, and increasing frequency of integrity measures.
GAIL has set up a group of specialists to monitor all pipeline parameters. About 6,500 km of the 11,000 km of natural gas pipeline the company operates have already been examined for their health and the process is underway for the rest.
