A planning method for offshore wind farm construction process based on discrete event-driven simulation and the application

The construction of offshore wind farms is highly complex, involving many factors at each stage, making it difficult to create an accurate preliminary plan. We propose a discrete event-driven simulation method for preliminary construction planning, which is both flexible and efficient. This approach is particularly suitable for large-scale offshore wind farms. The method begins by discretizing and modeling construction processes and key factors to build a simulation framework. Next, sequencing rules for activating discrete events are developed based on real construction practices, driving the dynamic simulation model. The result is a comprehensive simulation system that clearly outlines the construction timelines for various processes. A test on a real offshore wind project showed that this method accurately predicts manpower, material resources, and time requirements, considering specific influencing factors. Comparative validation with empirical-based simulation methods demonstrates that the integrated simulation system achieves a 9% improvement in accuracy for wind farm construction scheduling processes. This method also offers strategic long-term scheduling advice for future offshore wind farm projects.
