New Delhi: Petronet LNG, increasing capacity at its Dahej facility, proposes to build two additional liquefied natural gas (LNG) tank farms, taking the total number of such tanks at Dahej to six.

According to official sources, the company has two existing LNG tank farms and two are under construction.

Apart from these four, the company is all set to sign a memorandum of understanding with Gujarat State Petroleum Corporation (GSPC) for building two additional tanks at Dahej.

The total cost of construction is estimated at $300 million.

Currently, Petronet has a storage capacity of 5 million tonnes (since the company is working at 130 per cent capacity utilisation as it is operating at 6.5 million tonnes of capacity), which is likely to double once the ongoing construction of two tanks is completed.

The tanks have a capacity of 1,48,000 cubic metre.

With six tanks, the capacity is expected to go up to 15 million tonnes. Petronet is also planning to set up another receiving marine facility, which will include a jetty and a tressel at Dahej.

Draft required for LNG vessels is almost 13 metres, the second jetty will be on the similar lines as the existing jetty, which runs 2.4 km into the sea, sources explained.
