Precision Monitoring for Structural Integrity in Offshore Environments
WISE Group’s Structural Health Monitoring System (SHMS) is a robust, precision-engineered solution designed to monitor structural integrity and proactively manage offshore wind assets. Leveraging our advanced AIM technology, SHMS provides comprehensive data essential for maintaining safety, optimising maintenance strategies, and extending asset lifespan—making it an ideal choice for fixed and floating wind structures.
Monitor, Predict, Protect
n the demanding offshore environment, precise structural monitoring isn’t optional—it’s essential. WISE Group’s SHMS captures high-resolution vibration, displacement, and angular data, providing actionable insights to support predictive maintenance and fatigue assessments. By identifying potential structural issues at the earliest possible stage, SHMS helps operators avoid costly downtime and interventions, ensuring operational continuity.
SHMS continuously measures:
- Vibrations and accelerations (X, Y, Z axes)
- Structural displacement and deformation
- Modal behaviour (sway, torsion, resonance frequencies)
- Long-term structural trends and fatigue progression
- Structural responses to environmental loads
Advanced Inertial Measurement (AIM) Technology
Our proprietary AIM platform forms the backbone of the SHMS, combining multiple MEMS-based accelerometers and precision tilt sensors into a unified system. AIM sensors are configured strategically across structural elements to provide accurate measurements even under extreme offshore conditions. Enhanced by robust stainless-steel (IP67-rated) housings, AIM systems offer reliable, long-term data collection in the harshest environments.
AIM sensor capabilities include:
- High-precision 6 Degrees of Freedom (6DOF) measurement
- Exceptional noise reduction through grouped accelerometer configurations
- Real-time temperature calibration ensuring measurement accuracy
- Customisable data acquisition (sampling up to 1kHz) and flexible connectivity options (RS485, RS232, Ethernet, analogue)
Optimised Data Processing for Digital Twin Integration
WISE Group uses advanced non-real-time (NRT) methods to calculate structural displacement from acceleration data, delivering highly accurate results crucial for detailed structural analysis. Although this approach introduces a slight data processing delay, it enables superior accuracy, making it ideal for structural health assessments and digital twin modelling.
SHMS seamlessly supports digital twin strategies by providing:
- Detailed structural deformation data
- Precise fatigue analysis and lifecycle assessments
- Real-time integrity monitoring dashboards
- API-driven integration capabilities
Flexible System Architecture Tailored to Your Needs
Every SHMS implementation is carefully customised for client-specific applications. Systems typically include multiple AIM units arranged in a scalable matrix configuration, ensuring comprehensive structural coverage and redundancy. Integration of complementary sensors, such as optical strain gauges for stress measurements or wave radar systems for environmental monitoring, further enhances the capabilities of the system.
Typical SHMS configuration includes:
- Multiple AIM units with satellite sensor options
- Optical strain gauges for accurate fatigue tracking
- Stainless steel junction boxes with surge protection
- Rack-mounted industrial servers and intuitive software
- Remote data access and real-time visualisation capabilities
Innovative Bolt Monitoring Integration
Our SHMS can incorporate wireless bolt monitoring sensors, continuously tracking bolt preload and integrity. With battery lives of up to 20 years and IP68-rated robustness, these sensors significantly enhance safety by reducing the need for manual inspections. Data from bolt monitoring can be seamlessly integrated into the overall SHMS framework, enabling comprehensive structural oversight.
Key Benefits of SHMS
- Enhanced Safety: Early detection of structural anomalies reduces operational risk.
- Extended Asset Life: Informed maintenance and fatigue management decisions lengthen asset service life.
- Improved Uptime: Proactive monitoring prevents costly downtime.
- Environmental Durability: Robust, offshore-grade materials ensure consistent performance in extreme conditions.
