Offshore wind turbines structures
The greenhouse effect gave rise to an international effort to initiate alternative green energy sources. The fast development of inland wind farms, directed many countries toward the real great potential of wind energy – toward the sea. The sea offers much better wind sources, yet building on the sea is difficult and costly.
Wind Land is the only company specializes in a new concept of on-shore pre-installed offshore wind turbines (including their support systems). The technology is based on a proprietary technology consisting of buoyant structures made of OceanBricks (OBS) 3D concrete elements. The support structure in a form of a wide platform, is cast on-shore, and interconnects the elements to each other, in a dock. The platform is acting as a stiff superstructure, on top of which high tower and turbine are firmly connected.
The complete wind power installation is then floated and towed to the planed sit, where it is submerged to pre-leveled seabed. Being open to the sea water, the pressure inside and outside the structure is equalized at all times. The structure is therefore indifferent to sea depth. This last feature is revolutionary and unique in the industry.
The structure is fabricated in mass-production methods, and is almost free of the very costly marine works. The OBS WindLand is independent of sea conditions, as all installation works are made on-shore. There is also a big saving in costly dedicated marine equipment, which during harsh sea condition, must wait idle most of the project period.
The sea-work hinders the essential development and endangers the economic feasibility of the offshore wind industry. OBS technology can cut the investment on offshore wind farms by about 40%, bringing it to the same price level as the on-shore wind electricity cost.
The WindLand is Green! –
- Obligatory decommissioning is a heavy burden laid on any offshore installation. The WindLand platform will become very fast a beautiful artificial reef, a safe sanctuary for the sea flora and fauna, especially for endangered sea mammals, which no one would dare to destroy. This will save the wind farm's owner the decommissioning and its' execution-bond cost.
- The WindLand platform is freely resting upon the seabed, avoiding the need for harmful noisy hammering of piles into the seabed, that are deafening whales' sonar systems.
