INTRODUCTION

1.1

Project Overview Dai Hung Field is located at Block 05-1a at North-West of Nam Con Son basin within South-East continental shelf, Viet Nam, 260km far from Vung Tau seashore. This field was discovered in 1988 by DH-1X. In 2011, WHP-DH2 with existing system is operated to increase the capacity of associated gas up to 1 MMSCMD. Besides the associated gas there is considerable volume of natural gas located in bottom and middle of Mioxen layer. The overall Dai Hung Gas Gathering Project as show in figure 1 below:


















SPECIFICATION FOR GAS TURBINE COMPRESSOR PACKAGE Preliminary configuration of Dai Hung Gas Gathering Project is as follows: •

•

•

1.2

On WHP-DH2: Gas Cooler, Gas Scrubber, Gas Engine Generator, Corrosion Inhibitor Injection Skid, Electrical System, Instrumentation System, Fuel Gas System, Fire Fighting System, Telecommunication System and other Utility Systems. The 16” subsea gas pipeline (approximately 20 km) from existing 10” riser at WHP-DH2 to BK-TNG Platform and 16” Y-Tee for future connection. On BK-TNG Platform: 16” Riser, Slug Catcher, DH Gas Custody Metering System, DH Gas Compressor Suction Scrubber, DH Gas Compressor Package, DH Gas Compressor After Cooler, Fuel Gas System, Piping System, Instrumentation System, Telecommunication System, Open/ Closed Drain System, and other Utility Systems.
