Engineers India Limited (EIL) has successfully executed the development of India’s largest underground rock cavern for LPG storage, for Hindustan Petroleum Corporation Limited (HPCL) in Mangalore, Karnataka. The cavern is located within the premises of an existing LPG plant and has a storage capacity of 80,000 MT of LPG, making it the single largest LPG cavern in India. What makes this project even more remarkable is its first-of-its-kind design, with the cavern excavated beneath pre-existing surface facilities. This innovative approach allows for dual usage of land, significantly optimizing space utilization and setting a benchmark for future infrastructure projects. EIL served as the EPCM Consultant undertaking Project Management and coordination of all activities, Basic and Detailed Engineering of the cavern and associated facilities, Construction Supervision to ensure adherence to safety, quality, and timelines and Commissioning Assistance, leading to 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”, CMD EIL Ms. Vartika Shukla remarked while speaking on this achievement.
