Monopile Installation Spread – Moray West

Installation equipment for 15MW foundation

DEME successfully completed the installation of 29 foundations at Ocean Winds’ Moray West Offshore Wind Farm in Scotland, utilizing the Orion floating heavy lift vessel for the monopiles and the Apollo jack-up vessel for the Transition pieces. The remaining 31 monopiles were installed by Boskalis using the Bokalift 2. Moray West announced the commencement of first power production, marking a significant milestone in the project.

TWD was a key contributor to this complex, large-scale installation, providing a range of specialized engineering solutions that were crucial to the project’s success. On the Orion, TWD initially designed the monopile seafastening deck spread in 2022 and later optimized this spread for several other projects, including Moray West. Additionally, TWD was involved in developing the Motion Compensated Pile Gripper (MCPG) up to the basic design stage, enabling precise placement of foundations in challenging offshore conditions.

For the Bokalift 2, TWD’s expertise was evident in the design of several critical components, including the monopile lifting tool and the hammer seafastening, ensuring the safe and efficient installation of the monopiles.

Moreover, TWD’s contribution extended to the Apollo jack-up vessel, designing the transition piece (TP) seafastening, which supported the project’s overall success.

Project highlights:

• Versatile monopile installation spread for floating installation
• Noise mitigation deployment system
• Advanced monopile lifting tool
