Global Power Group, the power equipment business, will operate across all regions.

All four business units will be supported by a global strategy and business development function – focused on the development of market and regional strategies, customer relationship management and business acquisition, and a project delivery function – to “assure and drive project excellence” and leverage Amec Foster Wheeler's global talent and experience.High value execution centres and centres of expertise will support this activity.
