WInd energy – floating wind
Discover how an innovative floating wind turbine such as the TetraSpar Demonstrator is installed off Norway.
This is the fifth Floating Wind Turbine project Bourbon Subsea Services has been awarded since the company decided to develop its activities towards renewable energy in 2011.
The TetraSpar FWT is particularly innovative in comparison with the other prototypes already installed worldwide. The defining feature of the TetraSpar foundation concept is the modular ‘building block’ arrangement: each foundation is assembled from tubular steel modules, most of which are common to all configurations.
Manufacturing takes place in factories using industrialized methods, and their assembly near the site as well as towing are measured in days or weeks, instead of months. Another particularity of TetraSpar Demonstrator is its stability provided by a keel deployed 50m below the floater.
