RWG wins maintenance contracts for Siemens gas generators in Thailand

Published on: 

PTT has awarded RWG with multiple contracts for maintenance of Siemens aeroderivative gas generators. The latest awards encompass three Industrial RB211 GT DLE units and three Industrial Avon 200 gas generators in service at PTT’s five gas separation plants in Rayong Province, Thailand.

Work on these contracts, valued at approximately £8MM, will be undertaken at RWG’s Aberdeen, UK service centre. The scope of work includes engine disassembly, detailed inspection, component repair, re-assembly and performance test of each gas generator, prior to return to customer. The overhaul of both Industrial RB211 and Industrial Avon engines has already commenced, and is expected to be completed this year.


Charcrie Buranakanonda - Senior Executive Vice President, Gas Business Unit of PTT said the company operates the latest Siemens aeroderivative gas generators. “It is essential this equipment is reliable and efficient, so that we can maintain production and manage our operating costs effectively. RWG’s proposal was successful because it addressed both criteria and they have a strong track record of delivering on commitments.”

Mark Forsyth, RWG’s Industrial & Marine Business Director commented, “By combining RWG’s expertise in maintenance with an understanding of our customer’s business, we’re able to tailor our service solution to better align with PTT’s operational goals.”

RWG provides maintenance support for an additional gas separation plant (GSP) located at Amphur Khanom in Nakhon Sri Thammarat Province. PTT’s GSP unit four operates Siemens Industrial 501 gas generators and recently contracted with RWG for overhaul of a single Industrial 501KC5 machine, complete with Dresser-Rand GT22 power turbine. This work scope was completed at RWG’s Texas, USA facility, enabling PTT to consolidate support for Siemens equipment with a single service provider.
