Wind Tower Generator Structures Fabrication Technologies

Webinars 23 May 2024

Offshore Energy Technical Group Webinar
Wind Tower Generator Structures Fabrication Technologies and Quality

Who should attend?

The event is focused on current welding technology and fabrication standards for fabrication of heavy wall offshore structures for the offshore wind sector. The event should be of interest to anyone involved in design, fabrication and operation of offshore assets, with emphasis on windfarms, e.g. to fabricators, designers, weld engineers, quality control personnel and windfarm developers.

What will you learn?

The event is focused on the fabrication of heavy wall monopile and jacket structures for use offshore. These are highly utilised structures both in terms of peak loads, for example during installation, and fatigue requirements during operation. The challenge is to be able to scale up cost-effective production of “mass produced” assets while achieving the required quality and performance for over 20 years of operation with minimal maintenance.

The event will concentrate on high productivity alternatives of current technology such as submerged arc welding and will explore promising future technologies such as additive manufacturing and electron beam welding.

Experts from industry will be presenting on a range of topics:

  • Bart Theunissen, Manager Process Technology & Innovation, Sif on Practical Experience of Utilising Electron Beam Welding for Monopile Transition Piece Longitudinal Weld (Provisional)
  • Stephan Marre, Technical & Applications Director, Lincoln Electric on Improved Productivity Saw Process For Wind Turbine Towers
  • Declan Foley, Fabrication Quality Manager, SSER on Offshore Renewables Fabrication Standards
  • Andrew Woloszyn, Programme Manager, TWI Ltd on TBC
  • TBC, Lincoln Electric on Additive Manufacturing for Offshore Wind Industry
