GAIL hires drones to secure 15,000-km gas pipelines

The drones will be used to patrol the pipeline to detect physical abnormal activity like encroachment or intrusion on the pipeline

India Ltd, the country's biggest transporter, has deployed on pilot basis on its main trunk pipeline as it uses technology to secure its vast network, its director (pipelines) Ashutosh Karnatak said.

In the aftermath of the June 2014 accident at its pipeline in that killed at least 18 people, the state-owned firm has taken a number of initiatives to raise safety standards including replacing old and using advanced technology.

"We have hired one drone on a pilot basis for aerial surveillance of the pipeline in the Ravines in Madhya Pradesh," he told reporters here.

Based on the results, the company may decide to buy or hire more to monitor its 15,000-km pipeline network, he said.

The will be used to patrol the pipeline to detect physical abnormal activity like encroachment or intrusion on the pipeline.

For using drones, had to secure permissions from multiple agencies. Previously, the government had given permission to Indian Railways and the National Highways Authority of India (NHAI) for similar purposes.

As line patrolling is extremely difficult for pipeline sections passing through forests, rivers, environmentally sensitive areas and other inaccessible areas, would use for aerial surveillance of 200 kilometres for the Hazira-Vijaipur-Jagdishpur/Dahej-Vijaipur

has also started using satellite surveillance as well as PIDS or pipeline intrusion detection system to detect any breaches, he said adding the company has replaced old in the KG and Cauvery basin and Gujarat at a cost of about Rs 1,500 crore to prevent any accident.

A government probe into the June 2014 accident had highlighted safety lapses at the firm and prompted sector regulator Petroleum and Natural Regulatory Board (PNGRB) to slap a penalty.

Also, natural is being dehydrated and corrosion causing water, sulphur and carbon-di-oxide removed to prevent damage to and avert any repeat of the 2014 accident, he said.

Karnatak said will be used to detect encroachments around as they are a big safety hazard.

In the pilot, a drone will fly over the pipeline, capturing pictures and other data using smart technology. The data will be analysed to detect any potential hazard.

GAIL, at present, uses foot patrolling to spot encroachments and seeks local administration's help in getting them cleared.

will however not be able to detect any leakage, for which the company will continue to reply on sensors and patrolling, he said.

is using live satellite monitoring of the and is now integrating advance Unmanned Ariel Vehicle (UAV) with this system.

Pipeline securities is a major issue across the world and with recent progress in satellite sensing technology, availability of new high resolution satellites and object oriented image analysis, there is a possibility to introduce space technology for pipeline monitoring applications.

did pilot project on satellite monitoring on its 610 km Dahej-Vijaipur pipeline.
