The offshore wind challenge

Renewable energy :

The main challenge of offshore wind power is to produce clean, renewable energy on a large scale.
Wind turbines use the power of the wind to generate electricity without emitting greenhouse gases, helping to combat climate change and reduce dependence on fossil fuels.

France currently has several wind farms, including Saint-Nazaire, Fécamp and in the Mediterranean.

High production potential :

Offshore sites offer greater potential for wind generation than onshore sites because of the consistency and strength of offshore winds.
This makes it possible to generate more electricity from a smaller number of turbines.

According to a study by France Energie Eolienne, wind farms could supply up to 15% of France's electricity consumption by 2030.

Reducing pollution :

By using offshore wind energy, it is possible to reduce greenhouse gas emissions from electricity generation, thereby helping to meet the emission reduction targets set by many countries.

According to the International Energy Agency, offshore wind could save around 1.4 billion tonnes of CO2 worldwide by 2040.

Economic stimulus :

The development of offshore wind farms requires significant investment and creates jobs in the construction, installation and maintenance of wind turbines, as well as in related sectors such as engineering, logistics and research. This can boost the local and regional economy.

In France, the construction and operation of offshore wind farms could create up to 40,000 direct and indirect jobs by 2030.

The environment :

The installation of offshore wind turbines can have an impact on the marine ecosystem, particularly with regard to marine fauna, migratory birds and underwater habitats.

It is therefore essential to carry out in-depth environmental assessments to minimise negative impacts and strike a balance between renewable energy production and preservation of the marine environment.

Costs and technical challenges :

Offshore wind power presents technical challenges and higher costs than onshore wind power, due to the difficult conditions at sea, the need for special foundation structures and the complexity of maintenance.

However, as technology advances and experience is gained, costs are tending to fall progressively. According to the IEA, offshore wind energy costs have already fallen by around 40% over the last decade.

The essential tool for offshore wind energy :

Crew Transfer Vessels (CTVs) are essential for the operation of offshore wind farms. They enable crews to be transferred quickly and safely between the coast and the offshore wind turbines.

JM Sea, which specialises in shipbroking, assists and advises shipowners on the purchase or sale of new or used vessels, offering invaluable support in choosing the right CTVs for offshore wind projects.
