Bourbon SubSea Services has released a behind-the-scenes video of the TetraSpar floating wind demo off Norway.
TetraSpar is particularly innovative in comparison with the other prototypes already installed worldwide, according to Bourbon.
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, it said.
Manufacturing takes place in factories using industrialised 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 50 metres below the floater, the company said.
Bourbon Subsea Services successfully installed TetraSpar in August.
