Established in 1981, the Greenray Group of companies has been offering turbine package upgrades and maintenance to the Oil & Gas and Power Generation sectors for more than 30 years. Greenray’s primary focus is on supporting legacy gas turbines, which have been installed for over 25 years. 

Many members of our team have formerly worked for major OEMs, such as Siemens, Alstom and Dresser Rand, bringing a wealth of experience to our product range. Within the engineering and design departments, our team has amassed over 450 years of technical experience.

Integrated Turbine Systems (ITS) was created in 2014 and is a wholly owned subsidiary of the Greenray Group. ITS was formed to provide turbine package operators with a cost effective alternative to traditional service providers, without compromising on quality, reliability and safety.

The Greenray Group has been awarded and successfully completed a variety of major projects, including recent work on the revamp, installation and commissioning of three units on an offshore platform in India. Deterioration in equipment was identified due to environmental impacts and equipment age, which led the customer in deciding to refurbish the existing packages rather than replace with new. The work scope incorporated upgrades, control systems and parts replacement. Our expertise, coupled with support from a number of other key suppliers, allowed us to professionally service and provide the solutions that the customer needed within planned time scales.
