We are solving the supply chain challenge for floating wind - click here to learn more

Bassoe Technology is a recognized designer of advanced mobile offshore units, such as semi-submersibles and drillships, as well as designs of RoPax and cruise ships. In addition, designer of D-Floater and T-Floater floating wind platforms with focus on cost-efficient construction, logistics and supply chain for industrialized floating wind.

The future is coming, and it is floating

The Global Wind Energy Council states that floating offshore wind will reach full commercialization by 2030 with almost 16.5 GW installed worldwide and Clarkson Research predicts 1,300 floating turbines in operation 2030.

DNV predicts that floating offshore wind will generate 15% of all offshore wind energy by 2050 which equates to 264 GW or 15,000 floating wind turbines in operation. That is in average approx. 600 floating foundations per year until 2050. About 11.5 per week worldwide!

The large number of floating foundations will be a supply chain challenge and provide a strain on the global shipbuilding capacity. To meet the targets for green energy, floating foundations will have to be fabricated in low cost – high capacity shipyards and be transported to the turbine installation site. With the floating wind hulls of today, this is a huge challenge both related to transport and to meet the targets for efficient installation at the site.

D-Floater

We are proud to present our solutions to solve one of the major challenges of offshore wind; cost effective fabrication, “transportability” and fast installation at site.

The complete D-Floater (patented) floating wind hull can be transported efficiently stowed on a dry tow vessel. This allows for fabrication on multiple competitive shipyards and the hull can then be transported to a quay close to the wind farm installation site to have the tower and turbine installed. The package can be efficiently stored while waiting for its turn for tower and turbine installation.

By carefully designing the hull to accommodate as many assembly locations of tower and RNA as possible, we have succeeded in making a design with a tow-out draft of only 8 m with a 20 MW turbine installed. The shallow draft enables the tower and turbine installation in a port close to the floating wind farm which reduces the wet tow distance and as a result the time to deploy the units.

The 15 MW D-Floater design has been granted an Approval in Principle (AIP) certificate by ABS.

The 17 MW D-Floater design for typhoon condition has been granted an Approval in Principle (AIP) certificate by DNV (press release).

T-Floater

The T-Floater (patent granted) can be fabricated and transported either complete or in modules. The modules can also be manufactured in smaller shipyards for in-water assembly which opens the possibility for utilizing local shipyards which will benefit local content. The design process of the T-Floater has followed the same rigorous process as for semi-submersibles for the oil and gas market with the design and engineering being Approved in Principle by ABS and the design is proven by model tests.
