The oil and gas industry has increased focus on the need for reliable data management as this is essential to quickly understand the structural condition of assets. The demand is mainly driven by increased focus on environmental issues, life extension on aging structures and the need for key performance indicators to ensure safe operation and reduce the overall asset risk exposure.

It is the Operators’ responsibility to ensure that offshore load bearing structures are suitable for their intended purpose and that they are able to monitor the condition in a systematic manner. Many standards provide input and requirements related to this, e.g. Norsok N005/N006, ISO 19902/19904 and API RP 2SIM.

DNV Software provides state of the art software to support integrity management of the structural assets in the offshore industry. Our approach has been to combine in-depth DNV engineering knowledge with software engineering and this unique combination of skills is expressed in the Sesam Structure Integrity solution. The result is a software solution providing extensive support in management of structural integrity of offshore installations, and it provide tools enabling:

• Consistent reporting, interpretation and aggregation of asset integrity data including key performance indicators on work-progress, finding extent and severity, repairs.
• Inspection planning and inspection report compilation, inspection execution and finding reporting
• Reporting of repairs and mitigations
• Management of Computer Aided Engineering models linked with change management and statuses identifying to which degree damages and planned modifications has been implemented in the various regulatory finite element analyses.

Implementing the Sesam Structure Integrity will greatly reduce the probability of unplanned shutdowns and increase safety, as quality information about asset integrity enables management to take corrective actions at the right time. The complete track of asset modifications like pay-load updates, structural reinforcement, damages, repairs and CAE analysis represent vital input in case of emergency response or life extension studies.
