Abstract
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.
