4 min read

In order to meet the gas demand, Liquefied Natural Gas (LNG) is imported through Open General License (OGL) in the country and it is imported by the gas marketer under various Long Term, Medium Term and Spot contracts. The price and utilization of imported LNG is mutually decided by buyers and sellers. At present, country is having six (6) operational LNG regasification terminals operational with capacity of about 38.8 MMTPA (~ 140 MMSCMD).

(*Name plate capacity is 5 MMTPA but in absence of the breakwater, the terminal can only operate at 1.3 MMTPA at present)

The important terminal are Dahej (Gujarat), Hazira (Gujarat), Kochi (Kerala) & Dabhol (Maharashtra).

Hazira LNG Terminal: In this terminal LNG cargo is unloaded to the cryogenic tanks. The main components of the terminal are LNG jetty with cryogenic unloading arms, cryogenic tanks to store LNG at -160 degree Celsius. LNG pumps to boost pressure to 80-100 barg. LNG vaporizes, and send-out-pipelines carry gas to the delivery point which is located at a distance of 12.5 kms from the terminal. The LNG jetty has two liquid unloading arms both of which are cryogenic & are designed to unload LNG at -160 degree Celsius. Unloading of LNG can be done at a maximum rate of 11000 m3/hour. The LNG unloading is carried in cold condition by a 1.6 km pipeline to the LNG tankers. The terminal has two LNG tanks with capacity of 16000 m3 each. These tanks have pre-stressed concreate outer & 9% Nickel inner tank to hold the LNG at -160 degree Celsius. LNG cryogenic pumps are installed inside the tanks, which pump out LNG from the tanks at intermediate pressure. Finally the pressure is boosted to 100 barg before being sent to the regasification section. LNG is re-gasified in open rack vaporizers, using sea water as the heating medium. Terminal has three open rack vaporizers which are used to vaporize LNG. This was owned by Shell.

Kochi LNG Terminal: Kochi LNG Terminal was set up by LNG Petronet. It is South India’s first LNG receiving, regasification & reloading terminal with a capacity of 5 MMTPA. The terminal is at special Economic Zone (SEZ) of Puthuvypeen near the entrance to Cochin Port. The jetty is designed to receive LNG tankers between 65000 to 216000 cubic meters. Terminal has two full containment above ground LNG storage tanks of net capacity of 155000 cubic meter each. The terminal has been commissioned in August 2013 & reloading operation of South Asia was carried out in January 2015. First supply of LNG as bunker to small ships was carried out successfully in February 2015.

Dahej LNG Terminal: LNG Petronet has setup south East Asia’s first LNG receiving & regasification Terminal with a capacity of 5 MMTPA at Dahej, Gujarat. The capacity of the terminal has been expanded to 10 MMTPA and same is commissioned in June 2009. The expansion involved construction of two additional LNG storage tanks & other vaporization facilities. The terminal is meeting around 20% of the total gas demand of the country. The company has completed & commissioned the second LNG jetty at Dahej.

Dabhol LNG Terminal: GAIL has owned the LNG Terminal associated with 1967 MW Dhabol Power Station, operated by the Ratnagiri Gas & Power Pvt. Ltd. . It has regasification Terminal with a capacity of 5 MMTPA.
