Gemini - base case With GBM Pile Drill With Noise Mitigation
Simulated number of days required to install 160 foundations at Gemini
Installation time Weather delay

Evaluation of installation procedure performed by ECN
Simulation set up: • Based on Gemini Windpark • 150 foundations using 2 ships
Findings:
• Pile drill requires less steps during installation • Secondary metal work can be pre-installed
Results:
• Shorter installation time per foundation • Smaller weather windows can be used • Decreased risk of delay due to weather
