Inspection is a critical component of any Asset Integrity Management process. Inspection, however, is often expensive and disruptive. It is therefore important to maximize the value derived from the data, not only to help ensure ongoing operational integrity but also to optimize subsequent intervention or ongoing inspection, maintenance and repair (IMR) activities.

At ROSEN, we deliver industry leading Integrity Assessment support, ensuring that our clients get the most from their valuable inspection data. Our expert team of Integrity Engineers and technical specialists works closely with customers to provide pragmatic and proactive decision support to ensure operational integrity across the full asset lifecycle.

Following any inspection, key questions are:

What does the inspection tell me about the immediate integrity of my asset?

  • What is the severity of the anomalies detected?
  • Is my asset still operating within safe working limits?
  • Do I need to carry out any immediate investigation or repair?
  • Do any anomalies require a more advanced level of assessment?

What does the inspection tell me about the future integrity of my asset?

  • Are the current threat mitigation measures adequate?
  • Are the prescribed IMR routines effective?
  • What medium- or long-term intervention or rehabilitation activities are required?
  • When do I need to plan the next inspection?

ROSEN’s industry-leading integrity team is on hand to deliver. We use applicable industry codes and standards, taking into account local regulatory requirements and operating company guidelines.

On a daily basis, our engineers complete fitness-for-service assessments based on data from countless inspections. Where the first level integrity assessment identifies significant anomalies, we can complete more detailed advanced Level 2 and Level 3 assessments.

Our integrity engineers have direct access to an extended global team of Consultants and Subject Matter Experts (SMEs) covering a wide range of technical disciplines. This includes materials, welding, corrosion, finite element analysis, fracture mechanics, fatigue, flow modelling, inspection technologies, physics, statistics and data science.

With these services, ROSEN is able to give operators real-world decision support:

  • Prioritization of features that require immediate repair
  • Definition of multi-year repair and maintenance plans
  • Implementation of prevention and control measures

Our combined expertise brings together:

  1. World-class expertise in integrity threats, associated damage and assessment methods.
  2. Fundamental knowledge of the capabilities and limitations of the inspection systems we develop and deploy.

This unique offering delivers the ultimate in safe, reliable and cost-effective decision support.
