What is an offshore wind farm?

It is an installation that produces electrical energy with wind turbines positioned in the open sea, far away from the coastline. The wind turbines can be set on fixed structures or on floating platforms anchored to the sea bed. An offshore substation collects the electricity and transports it to land along underwater cables.

Various aspects that are similar to land-based wind farms need to be taken into account when it comes to the planning and construction of an offshore wind farm, such as the speed and direction of the wind and the connection with the grid, but it is also important to study the sea bed to ensure it can support the whole installation.

What kinds of offshore wind farms are there?

These can be categorised according to the depth of the water and the type of foundation used to support the wind turbines:

  • For a depth of up to 60 metres, foundations set on the sea bed can be used, such as jackets, a large steel pylon or a tripod with multiple anchoring points.
  • For a depth of over 60 metres, floating platforms anchored to the sea bed are installed using cables or chains, for example. This option is more respectful towards marine activity in the area where the wind turbines are installed.

Advantages and disadvantages of offshore wind farms

Offshore wind farms generate clean energy and diversity renewable energy sources, which is why they hold a great deal of promise for the future. Their main advantage is that they are installed in places where the speed of the wind is constant and towers do not need to be as tall as they are on land. It is also an inexhaustible source of energy, it does not generate any waste and it does not take up space on land.

They do have some disadvantages, such as the increased technical complexity, the higher installation costs compared to land-based farms and the potential impact on the marine flora and fauna. From an aesthetic point of view, offshore wind farms do have an impact, but it is minimal since they are less visible at sea.
