Floating Wind

Applying cost effective proven technology from the oil and gas markets to floating wind

With up to 80 percent of the world’s potential offshore wind resources located at water depths beyond the limit of the monopile, attention is turning to the prospect of floating foundations for wind turbines. Building upon a proven track record, IQIP offers attractive and cost-effective piling spreads, handling and lifting tools for floating wind farms.

The future of floating wind

A new report from DNV GL predicts that the capacity of floating wind will make up more than 20% of the offshore wind market by 2050. IQIP is very enthusiastic about these developments. The biggest advantage we see is that floating wind turbines can be placed in areas with stronger and more reliable wind and in deeper waters. In addition, the installation of floating wind also has great advantages compared to bottom fixed turbines. Safe and efficient port-side assembly is possible using quay cranes, and the turbine can be tugged out to sea by smaller vessels. This makes the installation safer and it is also better for the environment. It gives the potential for local supply chains and removes environmental problems from coastlines. IQIP is preparing to provide the right lifting, tensioning, and handling equipment for the most efficient, environmentally friendly, and safe installation of future floating windfarms.


Exploring the floating wind market with known techniques

At IQIP, we are using our knowledge and experience in the oil and gas and bottom fixed offshore wind market to develop equipment for the offshore floating wind market. This is, for example, our knowledge and experience in mooring installation and mooring line handling and tensioning. Our knowledge in this is especially useful after the floating wind turbine has been set up in the harbour and needs to be connected at sea to the mooring. Next to that, our equipment could be used for turbine assembly, for example with handling and lifting as IQIP has done on the Hywind Scotland project with the Flange Clamp Tool. Whatever solution is needed, there is always room at IQIP to develop new equipment or adapt current equipment for your project. For more information about the equipment we are currently developing for the floating wind market, check out this article on "Floating Wind - An ocean of opportunities".

Advantages of floating wind

  • Installation in areas with more wind and deeper waters anywhere in the world
  • Remove environmental concerns from shorelines
  • Possibility of assembly in ports                                           
  • Wind turbines can be towed to sea by smaller ships
  • Potential of local supply chain

First floating wind farm: Hywind Scotland Pilot Park

Put into operation in 2017, Hywind Scotland became the world’s first floating wind farm. The installation of its five six-megawatt turbines on spar-buoys was completed with the help of IQIP’s Flange Clamp Tool. The tool helps solve a potentially costly challenge in the installation of floating wind, namely that Spar type floaters, due to their large draft, typically require offshore assembly. Allowing for a temporary axial connection between the floating substructure and the tower, the Flange Clamp Tool can save time and resources in this process

Used during the Hywind Scotland Pilot Park: IQIP Flange Clamp Tool

Flange Clamp Tools are used to temporarily secure the axial connection between the flanges of the tower and the substructure of a wind turbine generator prior to and during the installation of permanent bolting. After installing the majority (or all) of the installation bolts, all Flange Clamp Tools are removed.

Once the Flange Clamp Tool is added to the structures, there is no need for personnel in the wind turbine during the installation procedure. This increases safety during offshore operations. In addition, this temporary connection also reduces the installation time (no vessel is needed during bolting), which increases the efficiency.

The Flange Clamp Tool is multifunctional and is mostly used at offshore floating wind projects, but can also be used in other on- and offshore projects.
