    Integrated Structural Monitoring System (ISMS)

    The Integrated Structural Monitoring System (ISMS) is entirely designed and developed by Solgeo for verification of asset integrity and safety conditions of offshore structures.

The problem
Offshore platforms are usually not equipped with instruments for measurements of structural health parameters. This issue impedes the verification of asset integrity and of minimum safety conditions for operations, by becoming a problem especially for aged platforms.

The absence of directly-measured structural data doesn’t allow for the assessment of correspondence between the real structure behaviour and its model, essential for the awareness of structural health.
Indeed, the knowledge of the structural behaviour is essential for important purposes like re-certification for life extension, revamping, conversion of use (e.g., for de-carbonization projects), etc.

The solution
Our Integrated Structural Monitoring System (ISMS) is a flexible, cost-effective, turnkey monitoring system for offshore structures. This solution includes different sensor networks, to thoroughly measure the real-time structural response to environmental excitations and for the verification of compliance with predefined threshold limits. The alarm service provides an early warning on potentially dangerous occurrences and allows to take actions to ensure safety operation and plan maintenance activities.

The results produced by the ISMS represent a valuable input for Model Updating and Digital Twin, and for verification of asset integrity, re-certification for operative life extension, revamping for conversion projects, relaxation of inspections periodicity.
