With the right kind of annual maintenance planning and implementation, the facility can be kept operational. Operational reliability is maintained and unexpected issues can be avoided. Correctly selected maintenance methods and components guarantee a durable plant.

What to take into account when carrying out power plant maintenance?


Saying ”Well begun is half done” is true when it comes to Power Plant maintenance. In addition to drawings, strength calculations and testing plans, accurate scheduling and proper resourcing in the maintenance itself is a prerequisite for success.


The right components with the right materials and strengths guarantee a long and reliable service life without unexpected surprises.


Which EN/ASME standard is followed? PED class? Which maintenance methods and what are necessary resources? What schedule is realistic? Do I need to make support modifications? t is worth ensuring the correct procedure, because otherwise the damage can be large and unexpected.


Plant maintenance requires special skills. EN/ASME standards, stress calculations, material choices, testing protocol and possible authority applications must be taken into account. With the help of a professional, you can get everything right at once and guarantee operational reliability.
