The scope of services:

During the operational phase, the client is required to perform a series of periodical inspections and continuous monitoring to regularly check the integrity of the equipment and assets, identify any change in the load bearing capacity of the structures and serve as a proof of the stability of the foundation elements.

These activities are a mandatory requirement to maintain the validity of the operational permit, which shall be reviewed on an annual basis at the BSH Annual Asset Integrity Meeting. Several activities have been defined in accordance with the relevant statutory requirements as specified under German or European law. The testing and certification scheduled ensure that the necessary equipment does not go out of certification.
