Engineers India (EIL) has successfully executed India’s largest underground rock cavern for LPG storage for Hindustan Petroleum Corporation (HPCL) at Mangalore, Karnataka.

Situated within an existing LPG plant, the cavern has a storage capacity of 80,000 MT, making it the single largest LPG storage facility in the country. What sets this project apart is its pioneering design, with the cavern excavated beneath pre-existing surface facilities, enabling dual land usage and optimal space utilization, setting a benchmark for future infrastructure projects.

EIL acted as the EPCM Consultant, overseeing project management, coordination of all activities, and executing basic and detailed engineering of the cavern and associated facilities. The company also supervised construction to ensure compliance with safety, quality, and timelines, and provided commissioning assistance, culminating in the successful “gas-in” of the facility.

“This project is a shining example of engineering excellence and collaborative execution of a complex mega project. The successful completion of this cavern will significantly strengthen India’s LPG storage infrastructure and ensure energy security for the nation,” said CMD EIL, Vartika Shukla.
