Risk based inspection and maintenance

Risk based inspection and maintenance is a procedure by which TÜV SÜD experts identify the potential degradation mechanisms and threats to the integrity of the equipment and assess the consequences and likelihood of failure. The inspection plan can then target the high-risk equipment and be designed to detect any potential degradation before it can threaten fitness-for-service.

Risk based inspections are crucial for optimising the operation and maintenance of industrial plants in various industries. It improves your plant's performance, availability and safety to meet the industry's financial, reliability and regulatory needs. It extends the lifetime of your plant by establishing a long-term testing and inspection procedure.

TÜV-RoiM (risk-oriented inspection and maintenance) is TÜV SÜD’s strategy for developing optimised, cost-effective inspection and maintenance programmes within an asset- and risk-management context.

The strategy combines reliability and risk assessments with information extracted from expert judgement, physical models and plant-specific and generic data.

This assessment differentiates critical components from non-critical components, helping you determine where special maintenance measures need to be taken.

We base our qualitative and quantitative techniques on internationally accepted standards and guidelines, and then individually tailor the solutions to your specific concerns. We offer to guide you during implementation or give practical support in conducting an RBI-assessment.

The TÜV-ROIM process consists of seven main steps:

1. Consultancy on all questions concerning the introduction of an RBI inspection and maintenance system.
2. Assessment of status and history, remaining life and fitness for service, operational events, component reliability, spare parts, resources and personnel.
3. Determination of specific measures and flexible, adequate inspection intervals, considering financial and regulatory criteria.
4. Identification and definition of process parameters and their limits as Integrity Operating Window (IOW) to monitor equipment degradation proactively while the process plants are in operation.
5. Development of optimised inspection and maintenance programmes in line with internationally accepted standards.
6. Implementation of industry-specific and customised solutions (including RBI software applications) for risk-oriented lifetime management of systems and components.
7. Training for your staff to implement and operate the RBI system.
