I wanted to send you a note to say thank you for you and your teams support over the past three days helping us work through our breakdown.   The swift commitment to committing resources and the brainstorming contributions were significant. I can’t help but think we wouldn’t be...

I just wanted to give you some feedback on the incredible effort your guys have made thus far in progressing a really challenging job and making it a successful outcome, under really difficult circumstances.The professional way that Shane and Anthony have conducted themselves is a credit to your...

TransAlta Brad

GTS team, I would just like to share a quick incident report which was entered into our system by one of our HV technicians, as part of the recent work at the JAN Sub Station. During the outage I was made aware of the fact our guys were pretty impressed with the level of professionalism shown by...

BHP Billiton Carl

The guys did a great job. I am very happy with the way GTS conducted themselves here. Hendrik appears to run the ship and the guys (and girl) really know what they are doing. I am always very hesitant going away from the people I know and have used before, but in your case it was all good.

Western Power Colin

Thanks for your help on the BUH job. Our executives were impressed with the photos showing how quickly you had managed to get the new transformer to BUH.

BHP Billiton Denis

Thanks to your two guys with maintenance and testing in trying environmental conditions, all done without any safety issues.


Just wanted to thank you for all the effort you put into our job. The job was completed on time, with high quality and no safety issues. This is evidence of your knowledge, preparation and experience. I don’t think we could have done anything better that we did, and that is a good...

Synergy Johan

Thanks for the quick fixing of our tap changer motor. Very impressive. There is also a number of other things that were done very well, for instance oil level gauge fixing, tap changer protection device fixing. Thanks also for the M4 unit transformer busing fix. Big improvement on the original...

TransAlta Geoff

I’d like to thank you and the boys for the excellent work you guys did. Nothing was too much trouble for the boys and we really appreciate that they could stay back longer than expected to test those other surge diverters. Everyone worked safely and professionally and there were no...

WesTrac Jeff

I just wanted to say thanks for the support you provided to our team late Saturday night. In this case you went well above and beyond, which was certainly appreciated by both Westrac and Newmont and resulted in the machine being returned to service at 2:30am Sunday.

Synergy Keith

Global Testing Services have conducted work safely and efficiently during the 2015 M6/M5 major maintenance event at Muja Power Station. Synergy would like to recognise supervisor Shane Langfield and his team for this achievement.

MMG Golden Grove Matt

Daniel was very thorough and picked up several anomalies with our relay settings which was good to see. All the guys worked well and were easy to get along with and accommodating to our needs with changing priorities as the job focus and schedule was changing quite a bit.    ...

Woodside Nathan

I was on holidays while the IS limiter and T17 testing was going on, but I do want to express my gratitude for the services you provided over that period. Once again, GTS and Doble have provided a fantastic service for the plant and Woodside as a whole.
