Maintenance Engineering

Unequalled expertise

Maintenance is a complex task that demands experienced experts capable of analyzing the requirements, engineering the maintenance, planning and inspecting the operations and finally managing the overall activity. Maintenance Engineering and Inspection is at the heart of this activity.

Optimized activities based on best practices

Maintenance Engineering usually starts during the engineering, procurement and construction phase of a new plant, when Dietsmann works hand in hand with clients to integrate their operational backgrounds, the clients’ specific knowledge of their installations and the geographical context. We then define optimized Maintenance Engineering and Inspection proposals based on best practices.


Our unequalled expertise in Maintenance Engineering is derived from our extensive plant Operation & Maintenance experience, ensuring the definition of all data and procedures is optimized. The first step is the breakdown of plant equipment into maintenance items and the definition of spare parts. This large amount of information is fed into OPERIOM, our unique proprietary analytic equipment database application. It contains all the key maintenance information and history on more than 10,000 different pieces of equipment, and it can be consulted online by any of our maintenance specialists, whenever they need to, and wherever they are in the world.


Dietsmann’s operational activities require the accurate, continuous monitoring of various parameters in order to achieve Key Performance Indicators and fulfill the client’s expectations. Towards this end, and to assist people on
site, a dedicated tool capable of managing the operating technical parameters of all the equipment deemed vital and critical for installations was designed. The key benefit of this tool is that it ensures all the experience Dietsmann has accumulated working on many different sites is capitalized and the evolution of Dietsmann’s performance can be monitored. It also enables its users to generate technical reports and have direct access to information, such as the results of maintenance technical indicators, the availability and efficiency of equipment and major events. This new tool is destined to play an important role in monitoring activities, accessing technical information and establishing a shared-knowledge database for the Group’s employees.

Optimum transfer of know-how

Dietsmann’s Maintenance Engineering and Inspection includes documentation management, maintainability and inspectability studies, the definition of and recommendations for spare parts and tools, procurement, warehousing and maintenance & inspection plans and procedures. Our clients also benefit from having a computerized maintenance management system (CMMS) defined and implemented for the start-up and updated during the life cycle of the plant. Using the same partner for Maintenance Engineering and Inspection as well as Operation & Maintenance services guarantees the optimum transfer of know-how and a smooth transition to the operational phase.
