Offshore wind farms have the potential to harness electricity at low fixed costs, which can foster positive energy security by providing a hedge against the price volatility of fossil energy. Wind energy is also expected to dramatically reduce carbon emissions from energy generation as it is a clean and renewable energy source. But one of the challenges is that it can be a costly and time-consuming installation.

As more countries shift away from unsustainable energy sources and fossil fuels, the demand for offshore wind energy has continued to influence innovation in the offshore wind sector, which is good news. This guide explores how to address the challenges of offshore wind farm constructions and make your project a success.

Locating assembly and staging facilities

According to offshore wind experts at, manufacturing, assembling, and transporting wind farm equipment is an important consideration in offshore wind energy generation. First and foremost, you have to consider the proximity of the rail infrastructure to the port for safe transportation of the critical components, the power infrastructure for manufacturing, and the available workforce.

Both rail and port facilities need environmental and geotechnical investigations beforehand to allow engineers to create designs that address the site conditions. This research is also helpful in acquiring approvals for the construction.

The required equipment

When constructing offshore wind farms, the foundations can be gravity-based structures, monopile, or driven piles depending on the ground conditions. Although there is still no easy answer to the optimal offshore wind structures in the US, one financially optimal solution depends on the availability of expensive European installation vessels, at least for the next few years. That means you may need costly supply barges to transport components like turbines to the site adding to the project’s costs.

Routing export cables

Many engineers will agree that one of the challenges of offshore wind farm installations is the seabed because you have to route the export cables from offshore wind turbines to the shore. Therefore engineers must consider the environmentally sensitive seabeds, archaeological artifacts, seafloor geology, potential fishing grounds and anchorages, and the landfill location. 

A good solution for landfall is horizontal directional drilling to erect the landfilling export cable under the beach to connect to the land. Besides civil engineering experts, an expert with deep knowledge of the coastal geology and soil conditions is required.

Connecting the wind energy to the electrical grid

Routing the export cable to the land is only one part of the puzzle because the line must also be connected to the national energy transmission grid. Therefore, knowledge of the current transmission system and substations, routing analysis, and the ability to acquire permits along the selected route is valuable. 

Potential community oppositions

Although offshore wind energy promises significant environmental and economic benefits, you must also consider the surrounding community. Therefore a clear articulation of the positive contribution of the offshore wind farm can help communities understand the benefit of the project as a domestic energy resource.

The takeaway

To achieve an offshore wind energy project, you need the help of engineers and scientists who understand the local regulatory and social environment to address any challenges better.
