Where is Tangguh LNG Site?

Helfia Nil Chalis - July 2012

 

Tangguh LNG Site is located at Bintuni Bay, West Papua, Indonesia. Before the plant was built, there were about 100 families lived at the area. The company built a new home for them and moved them to the west side of the LNG plant area. The area is called Tanah Merah Baru. Babo is the nearest town from the plant. It takes one hour by boat or 15 minutes by chopper. Babo was an abandoned air strip built during the world war II.  If you travel from Jakarta to Tangguh LNG Site, you should take company charter flight leaving from Halim Perdana Kusuma Airport at 22.00. You will arrive at Biak early in the morning 5 am Papua time. You then should take smaller air plane such as Dash-8 or Skyvan to Babo. To go to Tangguh LNG Site from Babo you should take speed boat or chopper.  ​You will arrive at Tangguh LNG site around 9 AM local time.

What is Tangguh LNG?

Helfia Nil Chalis - July 2012

Tangguh LNG is a name of an LNG Site located at Bintuni Bay, West Papua, Indonesia. It is an LNG manufacturing company operated by BP Berau Ltd, a subsidiary of BP (previously known as British Petroleum). LNG is an abbreviation of Liquefied Natural Gas. It is literally natural gas which is cooled to a temperature of 160 deg C below zero degree to change its phase from gaseous form to liquid. A temperature below 100 deg C is also called cryogenic temperature. At this temperature LNG is at quite stable in liquid form.

Tangguh LNG Facility
Helfia Nil Chalis July 2012

Tangguh LNG has two process trains. Train-1 and Train-2 have installed capacity of 3.8 million tons per annum each or 7.6 mpta total. Gas supply is taken from two platforms VRA and VRB. Both platforms located north of LNG site at Bintuni bay approximately 14 km from shore. VRA platform has 6 wells while VRB platform has 9 wells. Each well has installed capacity of 240 MMSCFD gas production. Each platform is connected to onshore receiving facility with 24" pipeline. Each pipeline has capacity of transporting gas at 1050 MMSCFD.

How much gas is required to feed both Train-1 and Train-2 at maximum rate? It is approximately 1,400 MMSCFD. In other word, one pipeline could supply 1.5 trains. Is there any minimum rate that we must maintain through the pipeline? Yes, there is or otherwise an accumulation of hydrocarbon condensate might be formed in the pipeline in particular at the low points under the water, If we let this happens, the pipeline could be blocked by hydrocarbon condensate and gas could not be transferred through the pipeline any more.
