Owned by PTT LNG Company Limited, and located southeast of Bangkok in the Rayong province, it will be Thailand's first LNG Receiving Terminal.
The construction
started in late 2007 and is scheduled to be completed in Q2-2011, with commercial operation start-up in Q3-2011.
GS Enginering &
Construction Korea is part of the consortium managing the project and plant instrumentation. Whessoe PCT is the LNG storage tank management system
integrator.
Each of the two 160,000 m3
storage tanks (phase 1) will be equipped with:
- Two Rosemount RTG 3960 radar gauges for primary and secondary level
measurement
- One Rosemount RTG 3960 radar gauge as a High Level Alarm device
- Two Rosemount Data Acquisition Units
- Two multiple spot temperature sensors (cryo version)
- One Whessoe 1146 LTD (Level, Temperature, and Density) profile meters
The redundant tank gauging system solution, also includes two redundant Rosemount 2160 field
communication units, and a redundant LNG Manager inventory management system,
from Whessoe PCT.
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. Installation of the equipment will be carried out towards the end of 2009, and plant operation will start in 2010.
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 m
3 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.
The delivery includes equipment for one tank, 46 m (150 ft) tall and with a diameter of 30 m (100 ft):
- One Rosemount RTG 3960 for secondary level measurement. The relay
outputs in the radar level gauge are used for pump-and valve shutdown
- One LTD 6290 for primary level, combined with
level, temperature- and density profile measurement
The system solution comprises integration to the Foxboro DCS via the RS485 interface.
CB&I (Chicago Bridge & Iron Company N.V.) was the contractor, also responsible for building the tank.
The 200,000 ton per year LNG plant is situated in Erdos, inner Mongolia, China.
Operation started up on November 30 2008, and reached full capacity only 10 days after.
It consists of a liquefaction plant and a 10,000 m3 storage tank.
The storage tank is equipped with Rosemount RTG 3960 for High Level Alarm (HLA).
Chemtex was the contractor, responsible for project management and engineering.
