Drones Hired By GAIL To Protect Gas Pipelines, Uphold Aerial Scrutiny With Satellite Technology
The largest gas transporter of the country, GAIL India Ltd, has set up drones on its key trunk pipeline on a pilot basis as it employs technology to protect its enormous network, as said by Ashutosh Karnatak, Director. After the consequences of the June 2014 incident at its pipeline killed around 18 individuals in Andhra Pradesh, the state-owned organization has undertaken several initiatives to increase safety standards comprising substituting old pipelines and making use of advanced technology.
Karnatak said, “We have employed a drone for aerial inspection of the HBJ pipeline on a pilot basis in the Chambal Ravines in MP.” Based on the outcomes, the firm might settle on to hire or purchase more drones to supervise its pipeline network of 15,000 km. The drones will be utilized to watch the pipeline to sense physical unusual activity such as intrusion or encroachment on the pipeline.
GAIL, for employing drones, had to take approvals from several agencies. The government earlier had given approval to the National Highways Authority of India and the Indian Railways for analogous reasons. As line supervision is very tricky for pipeline fragments passing through rivers, forests, environmentally susceptible regions, and other unreachable regions, GAIL would employ drones for above ground supervision of 200 km for the Dahej-Vijaipur/Hazira-Vijaipur-Jagdishpur pipelines.
The state-owned firm has also begun using pipeline intrusion detection system and satellite surveillance to sense any breaks, he said mentioning that the firm has changed old pipelines in Gujarat and the Cauvery & KG basin at an expenditure of around Rs 1,500 Crore to avoid any mishap. A government investigation into the June 2014 mishap had emphasized safety drifts at the company and impelled sector controller Petroleum and Natural Gas Regulatory Board to smack a fine
Karnatak said the natural gas is also being dehydrated and deterioration causing sulfur, carbon dioxide, and water taken out to avoid break to pipelines and prevent any reoccurrence of the 2014 incident. He mentioned drones will be utilized to spot intrusions around pipelines as they are a huge safety risk. In the trial, a drone will hover over the pipeline, taking images and other information using smart technology. The information will be scrutinized to identify any likely danger.
At present, GAIL utilizes foot inspection to detect intrusions and asks for help from the local administration to get them cleared. However, drones will not be capable of sensing any seepage, for which the firm will carry on to respond to sensors and inspection, he said. Live satellite monitoring is used by GAIL for pipelines and now is incorporating advance Unmanned Ariel Vehicle with this system.
