Q.Which one of the following is known as 'Big Inch' pipeline ? (A) Iran - India via Pakistan (B) Iran - China via Afghanistan (C) Hazira - Vijaypur to Jagdishpur (D) Gulf of Mexico to northeastern USA

The development of a robust energy infrastructure is vital for any nation's economic growth. In India, natural gas plays an increasingly important role as a cleaner alternative to traditional fossil fuels. To transport natural gas from production sites or import terminals to consumption centers (like power plants, fertilizer units, and city gas distribution networks), an extensive pipeline network is essential. Public Sector Undertakings (PSUs) have been instrumental in building this critical infrastructure. The question asks about the specific organization responsible for one of India's earliest and most significant cross-country gas pipelines.

1. Understanding the HVJ Pipeline: The Hazira-Vijaipur-Jagdishpur (HVJ) pipeline is a landmark project in India's energy sector. It was India's first major cross-country gas pipeline, designed to transport natural gas from the western coast (Hazira in Gujarat) to landlocked northern states, primarily to feed fertilizer plants and power stations. Its construction marked a significant step in establishing a national gas grid.

2. Identifying the Responsible Organisation: The construction and operation of such a large-scale gas transmission network require a dedicated entity focused on gas infrastructure.

   • Gas Authority of India Limited (GAIL) was established in 1984 specifically for this purpose. Its primary mandate was to create and operate the gas transmission and distribution network in India. The HVJ pipeline was GAIL's flagship project, commissioned in phases starting from 1987.

3. Evaluating Other Options:

   • (A) Hindustan Petroleum Corporation (HPCL): HPCL is primarily involved in refining crude oil and marketing petroleum products (like petrol, diesel, LPG) through its vast network of retail outlets. While it deals with petroleum, its core business is not large-scale gas pipeline construction. …

Pipeline transport represents one of the most efficient and economical methods for moving liquids and gases over long distances. This infrastructure is particularly vital for the energy sector, facilitating the continuous flow of crude oil, refined petroleum products, and natural gas from production sites to refineries, distribution hubs, and consumption centers. Unlike other modes of transport such as rail or road, pipelines offer a continuous, weather-independent, and often more secure means of delivery, significantly reducing transportation costs and environmental impact per unit volume.

During World War II, the United States faced a critical challenge in supplying crude oil to its industrial heartland in the northeastern states. German U-boats posed a significant threat to oil tankers sailing along the Atlantic coast, making sea transport perilous and unreliable. Rail transport, while safer, was slow, expensive, and strained by the demands of wartime logistics. To overcome this bottleneck and ensure a steady supply of oil for the war effort, a monumental infrastructure project was undertaken.

This project involved the construction of two massive pipelines: one for crude oil and another for refined products. The crude oil pipeline, due to its unprecedented diameter of 24 inches, became famously known as the 'Big Inch'. Its companion, a 20-inch pipeline for refined products, was dubbed the 'Little Big Inch'. These pipelines stretched over a thousand miles, originating from the oil-rich Gulf Coast region, primarily Texas, and terminating in the industrial centers of Pennsylvania and New York.
