Aggreko - which supplies temporary lighting and power to events such as the Winter Olympics and World Cup competitions and provides power for oil and gas plants around to world - expects a full return on its investment within two years.
Moving to an internal application service provision model of software delivery will help Aggreko to standardise its processes worldwide in its drive to become a global business.
Using Java-based software from Intentia it will run sales, marketing, business administration, engineering and maintenance software from Sun Solaris servers based at two locations - one in Glasgow and one in Houston, Texas.
Tom Armstrong, global chief information officer, said, "This will allow us to standardise business processes and maintain similar levels of quality globally.
"We want to make sure that geography is not an issue in the way our business operates," he added.
Armstrong said that the main challenges were accommodating numerous time zones and languages - a problem that was overcome by rigour in the design stage of the system.
The physical network is a combination of dedicated and public lines, procured from a major network provider, which allows offices set up in remote locations to dial in and receive the same access to enterprise software as a fixed office site.
