Boat Landing Installation Aid – Nordsee One

Precise installation of the lower boat landings through the splash zone

DEME installed 54 wind turbine foundations at the Nordsee One offshore wind farm in the German North Sea, using their jack-up vessel, Innovation. To help with the installation, TWD designed and provided fabrication supervision for various seafastening structures.

One of the most challenging features of this project was the installation of the lower boat landings. To ensure precise positioning of the boat landing through the splashzone without damaging the coating, TWD designed a boat landing installation aid (BIA). The BIA enabled the crew to perform a complex lift and remotely install the lower boat landings. This led to a quick, safe, and efficient installation.

 

Project highlights

  • Precise positioning and installation of boat landing
  • Fast in operation
  • Preventing coating damage to structures
  • Re-use of existing secondary steel installation tool also designed by TWD
