HiveWind: a semi-submersible floating steel platform for offshore wind turbines

Towards a modular future

HiveWind is a semi-submersible floating steel platform for marine wind turbines with an output in excess of 15 megawatts (MW), developed and marketed by Sener Renewable Investments and Nervión Naval-Offshore.

HiveWind is made up of six low-height columns arranged in a polygon shape, which facilitates construction and reduces the logistics requirements of the supply chain. Rectangular struts are arranged in a horizontal plane, avoiding complex connection structures and limiting element reinforcements. These are linked perpendicularly on the flat sides of the columns, avoiding complex shapes in the connections. One of the columns is located in the center of one of its sides, and connects to the wind turbine tower through a transition piece.

The platform is equipped in accordance with the environmental and metoceanic requirements of each site using damping plates located at the base of the buoyancy elements (columns) and the connection struts. The structure, in accordance with the described architecture, provides the platform with suitable stability, high buoyancy inertia, reduced dimensions and high structural efficiency.

Advantages

Modularity

HiveWind consists of three main elements that are repeated in the design: columns, bracings, and heave plates. Each of these elements is composed of identical manufacturing blocks so that the degree of standardization is superior to state-of-the-art concepts.

Easy construction

The concept is based on polygonal sections, flat panels and flat welds, which facilitates construction and reduces the logistical requirements of the manufacturing blocks.

Low steel weight

Structurally, the foundation requires low scantlings and consequent weight and cost reduction.

Low draft

Easy WTG assembly

The WTG tower is installed in the external part of the platform, on the central column of the side of the triangle.

Adaptability

The simplicity of the design allows it to be governed with a few fundamental parameters to adapt to the given conditions without affecting productive means or logistical or supply needs.

Easy to scale up

Turbine suppliers are expecting to develop a WTG in excess of 20MW in the next decade. HiveWind has been conceived to be easily scalable for larger turbines. The extra trust of larger WTG can be easily compensated by slightly increasing the height of the six columns, barely affecting the manufacturing process.

Ease in the local supply chain

the foundation configuration is adapted to existing construction methods in shipyards and to supply chains with a lower degree of specialization. This allows logistics to be optimized and local content requirements to be assumed for the deployment of floating offshore wind power.
