Monopile Deck Spread Design – Boreas Offshore Installation Vessel

Design of an integrated monopile deck spread

In collaboration with Van Oord, TWD designed the full monopile deck spread for the Boreas installation vessel. The solution supports efficient and reliable offshore wind installation across a wide range of monopile sizes.

Key elements include a 4-lane seafastening system, an upend hinge, and a monopile gripper with integrated noise mitigation deployment.

Project scope

• Design of major monopile deck equipment
• 4-lane monopile seafastening
• Seafastening for a wide monopile diameter range
• Upend hinge
• Monopile gripper with integrated noise mitigation
  
  Technical highlights
  
• Handles a broad range of monopile sizes
• Integrated design for efficient installation
• Combined handling and noise mitigation
• Strong load distribution for heavy piles
• Interface with WTG deck spread to reduce mobilization time

Project Challenges

• Wide variation in monopile sizes
• Integration of multiple systems
• Balancing flexibility and strength
  
  A practical, future-ready solution that supports efficient offshore wind installation.
