Innovative floating platform design

TRIWIND is a hollow, monolithic concrete structure designed to withstand demanding environmental conditions and dynamic sea pressures while maintaining superior naval stability and virtually negligible oscillations.

The TRIWIND platform consists of a series of internal cells that provide both buoyancy and inherent damping to the structure. By allowing communication between some of these cells and the surrounding water, ballast levels are naturally regulated without the need for additional onboard systems. This internal cell network also acts as an extra layer of structural safety, preventing any water ingress from propagating beyond a single perimeter cell, thus preserving the overall stability of the platform.

The wind turbine is centrally positioned to ensure efficient stress distribution across the interior walls. This, combined with the system of internal sea-connected cells, ensures stable behavior and optimal structural performance.

A key feature of the TRIWIND design is its ability to be transported with the wind turbine pre-installed, eliminating the costs, complexities and risks associated with offshore installation and enabling faster, safer and more cost-effective project execution.

Rapid slip-forming fabrication

The unique design of our TRIWIND technology enables floating platforms to be constructed and assembled in days. Using proven slip-forming fabrication, TRIWIND platforms are manufactured in-port using conventional materials and local resources. With a low rebar density and no post-tensioning elements, the fabrication process is comparatively simple and straightforward. Explore our diagram below for detailed insights into each stage in the slip-forming process…

Station 1

Here, the preparation of the formwork takes place before the lower slab is concreted. Once cured, the working platform is lowered, rebar is positioned and the vertical walls are slip-formed. An IP-CCV skidding system then moves the unit to Station 2.

Station 2

The placement grid for the upper slab is added before the pouring and vibration of in-situ concrete for the upper slab. The concrete of the upper slab is cured at Station 2, then a skidding system moves the slab to Station 3.

Station 3

On-deck equipment is installed and the floater is painted prior to being moved via the skidding system to a load-out barge.
