Two gleaming new LNG tanks rise at Dahej

Two massive new LNG storage tanks are rapidly and visibly taking shape at Dahej, with much of the structural work almost completed, triggering hopes the terminal’s chronic problems with overcapacity will soon be over for good.

“Earlier there were just four tanks at Dahej,” reports a frequent visitor. “But now everybody for miles around can see six structures.

” When contacted, a Petronet-LNG source confirms work is moving fast on the two 170,000-cubic metre tanks under-construction by Japan’s IHI which won the $160m contract in December 2013. “The twin tanks should be ready by November 2016,” he says.

“GAIL and GSPC have each booked one tank and are pushing us to complete work.” Dahej faced problems with its four old tanks full to the brim for most of 2013 and 2014 because of wide fluctuations in R-LNG send-out by off-takers GAIL, IndianOil and Bharat Petroleum.

Ships had to wait at anchorage as there was no room for their cargoes. Some cargoes were even diverted to Hazira and Dabhol.

“Additional storage will be a relief,” adds Petronet-LNG. Our source adds the new tanks will be taller than the four old tanks, each 63.5-metres high.

Both will have inner shells with 9% nickel plates to hold LNG at minus 160 degrees centigrade. Resilient blankets and foam glass wool will be used to insulate the tank shell and deck.

Dry sand and foam glass will insulate the bottom.
