Man Diesel & Turbo compressors bring in gas from offshore Vietnam

Published on: 

PTSC Mechanical & Construction Ltd. has commissioned MAN Diesel & Turbo to supply two compressor trains for the Sao Vang and Dai Nguyet gas fields’ development project in Vietnam.

MAN’s compressor trains are to be used to export the gas from the offshore platform to the onshore receiving terminal at Dinh Co. The gas fields in the Nam Con Son basin are located 500 km south of Vietnam’s largest city Ho Chi Minh City. Japanese petroleum company Idemitsu Kosan is the end customer and operator of the new platform.

The order comprises two booster + export gas compression trains, each consisting of two RB35 barrel-type compressors, driven by a 13 MW Solar gas turbine. The compressors dry gas seal system will use technology features of MAN’s standardized U-Pac solution system, which the company said has proved successful within the Oil & Gas market over the past years. In order to meet the future field conditions, the compressor selection required special attention, so that a replacement back-to-back arrangement can be accommodated in the current inline casing, the company said.


MAN Diesel & Turbo will manufacture the compressor systems in Zurich, Switzerland. Both trains will then be string tested at the Multi-Purpose Open Air Test Facility of MAN in Oberhausen, Germany. After delivery in spring 2019, the installation and commissioning works in Vietnam will be the responsibility of the company’s regional hub in Kuala Lumpur.
