Coupled Dynamic Analysis and Experimental Validation of a 1:15 Scaled Multi-Purpose Offshore Platform Prototype

Summary

This study presents aero–hydro–servo–elastic coupled numerical models for a 1:15 scaled prototype of an integrated offshore platform combining wind generation, wave energy conversion, and aquaculture, tested at an Italian offshore site. Time-domain analyses were validated against field measurements, with platform motion predictions showing mean absolute errors of approximately 1 degree for roll and pitch, demonstrating model accuracy. The work provides methodological reference for designing and validating multi-purpose offshore renewable platforms with integrated food production systems.

Regional applicability

The study was conducted in Italy and demonstrates feasibility of integrated offshore renewable-aquaculture platforms in European coastal waters. The modelling framework and validation approach are potentially transferable to United Kingdom offshore conditions, though site-specific environmental loading and regulatory requirements would require local calibration.

Key measures

Platform roll and pitch motions (degrees), mooring line tension forces (N), wind turbine responses, mean absolute errors between model predictions and experimental records

Outcomes reported

The study developed aero–hydro–servo–elastic coupled numerical models for a multi-purpose offshore platform integrating wind, wave energy, and aquaculture, and validated predictions against field-experiment data. Platform motion, mooring tensions, and turbine responses were compared between model predictions and measurements.
