Pluto LNG Project, Western Australia

The Pluto LNG project is probably the fastest developed LNG project from discovery of the gas field in 2005 to the production of the first gas in late 2010.

The Pluto project is a joint venture between Woodside (90%), which also is the operator, Tokyo Gas (5%), and Kansai Electric (5%). CB&I is the contractor.

The tank gauging system consists of equipment for five tanks (two LNG tanks and three condensate tanks), and includes:

  • One radar gauge, type Rosemount RTG 3960 per LNG tank for Hi-Hi level alarm
  • One radar gauge, type Rosemount RTG 3950 per condensate tank
  • One FCU, type 2160

Whessoe Process Control is the system integrator and is supplying LNG inventory management software, servo gauges, type 1143 and LTD gauges, type 1146.

Gas will be processed from the Pluto and Xena gas fields, located in the Carnarvon Basin about 190 km north-west of Karratha, Western Australia. The Pluto gas field is estimated to contain a total dry gas volume of 4.4 trillion cubic feet (Tcf). The smaller Xena field holds an additional 0.6 Tcf volume gas reservoir

Construction of the storage tanks and fabrication of the offshore and onshore infrastructure is underway.

Qatargas II project

The project includes a complete system delivery for five tanks, made in October 2007.

  • Each tank is equipped with three radar gauges, type Rosemount RTG 3960, mounted on still-pipes. One gauge is used as a primary level device, another is used for secondary level and the third for Hi-Hi and Lo-Lo alarm detection. In this project, radar is the preferred technology for all three independent measurements
  • Each tank has two LTD 6290 Level, Temperature and Density profilers
  • Each tank has one dedicated PC with the LMS inventory and management software in the control room. Tank data is also fed into a DeltaV host computer system
Qatargas II comprises some of the world’s largest Prestress Concrete LNG storage tanks, 50 m high and with a net capacity of 140 000 m3 each.

The first tank is estimated to be in operation in early 2008, with the next ones being started up within one month intervals. IHI (Ishikawajima-Harima Heavy Industries Co. Ltd), a leading Japanese engineering company, is responsible for tank construction and instrumentation within the project. The Qatargas II project is split between Qatar Petroleum (65%), ExxonMobil (18.3%) and Total (16.7%). The project provides two additional very large gas liquefaction trains at the Ras Laffan industrial city natural gas facility in Qatar. Each new train is capable of processing in excess of 5.3 mtpa of natural gas for export by LNG tankers.
