The COIN work plan is structured to deliver three major technology innovations through an integrated and coordinated framework. These are: (WP1) an innovative connector (CME) to subsea infrastructure, developed through control co-design (CCD) enabling active peak load limitation and damage prevention; (WP2) a digital-twin-based health monitoring (HM) system; and (WP3) a health-aware control (HAC) framework. Complementary to these, (WP4) develops an AI-based real-time wave prediction algorithm using hybrid wave sensing techniques to provide accurate second-by-second input to control frameworks.
The design and optimisation processes rely on dedicated case studies, multi-objective optimisation, and reliability-based modelling to achieve optimal FEED-level design and risk-based decision-making. WP5 supports these developments through comprehensive hydrodynamic wave basin modelling, providing experimental data for validation of the prediction algorithms, digital-twin framework, and control systems.
Technology validation (WP6) will ensure the achievement of TRL 5 through large-scale testing in industrially relevant environments at TUBS’ GWK+ and Quoceant’s dry-rig facilities. WP7 provides a techno-economic life-cycle assessment and extended LCOE modelling framework, ensuring that all innovations are balanced in terms of technical performance, cost, and environmental impact.
Two transversal work packages run throughout the project: WP8 focuses on exploitation, dissemination, and communication to ensure broad outreach and uptake of COIN’s results, while WP9 covers project management and coordination to guarantee efficient implementation and delivery of outcomes.
