Petronet-LNG plans second jetty at Dahej terminal

Vol 10, PW 24 (05 Apr 07) Midstream & Downstream

Petronet-LNG is proceeding with plans to build a second jetty at its Dahej LNG import terminal.

An industry source tells us UK-based consultant HR Wallingford has been commissioned to carry out marine impact studies for a second jetty, expected to cost $150m. Why does Petronet-LNG need a second jetty With its existing jetty, Dahej can accommodate 11.5m t/y LNG.

“This will mean one tanker coming in every alternate day,â€‌ says an industry source. But the result will be tight schedules and potential disruption if there’s a mishap, forcing tankers to anchor at sea.

“Once Dahej goes beyond 10m t/y it is advisable to have another jetty in the interests of flexibility, safety and security,â€‌ adds a source. HR Wallingford is expected to submit its final report sometime this month (April).

A first, preliminary report, by Wallingford says the second jetty should be located on the south side of the terminal. “Petronet-LNG was earlier looking at the option of having a new jetty on the north side,â€‌ says a source.

“The jetty could have come up on the north side but as a matter of abundant caution Wallingford suggested the south side.â€‌ Another jetty for the Dahej solid cargo port is about to be constructed one-km north of Petronet-LNG’s present jetty; next to that, another kilometre away is the GCPTCL jetty and next to that is the Birla copper jetty.

International norms say there must be a minimum 500 metres distance between jetties, and since there are no such constructions on the south side, Wallingford recommended the new jetty be built there. Another reason for choosing the south side is that all the onshore LNG storage tanks proposed for Petronet-LNG’s capacity doubling and future tanks will be on the south.

“There’s no space on the north side,â€‌ adds a source. “If the tanks are coming up on the south side, it makes sense to have the jetty on that side, otherwise the pipes will travel a longer distance and clutter up the terminal.
