Can spare parts be part of the contract?
Yes. Our procurement team sources and supplies the parts, so maintenance planning and supply are handled together.
Which plants do you support?
Power plants and substations, oil and gas facilities, water and wastewater treatment plants, steel plants, mines and cement plants.
Do you use software and AI in maintenance work?
Yes. Our software team develops the tools and AI models we use for maintenance data, document control and reporting.
