First Semi-Submersible Floating Offshore Wind Farm Surpasses Production Expectations

In its four years of operation, the world’s first semi-submersible floating offshore wind farm, WindFloat Atlantic, has surpassed anticipated production figures, achieving a total cumulative output of 320 GWh.

Connected to the grid by the end of 2019 and fully commissioned in 2020, the floating offshore wind farm was developed by the Windplus consortium, comprising Ocean Winds (a joint venture between EDPR and ENGIE), Repsol, and Principle Power.

The pioneering wind farm consists of three platforms, each supporting one 8.4-MW Vestas turbine. These are anchored with chains to the seabed and connected to the onshore substation in Viana do Castelo, Portugal, through a 20-kilometer cable.

The project’s electricity production has steadily increased each year, reaching 78 GWh in 2022 and 80 GWh in 2023.

As of July 2024, the 25 MW floating wind farm recorded a total cumulative production of 320 GWh, providing power annually to over 25,000 households in Viana do Castelo. This achievement has prevented more than 33,000 tonnes of CO2 emissions and created 1,500 direct and indirect jobs, according to Ocean Winds.

Ocean Winds remains committed to monitoring and enhancing the environmental performance of the WindFloat Atlantic wind farm throughout its lifecycle. The project has been shown to have minimal impact on the seabed and biodiversity, with surveys identifying over 270 species coexisting with the wind farm and no significant adverse effects on marine mammals or endangered bird species.

Additionally, surveys indicate that the floating structures have fostered marine life, contributing to a conservation and reef effect underwater, stated Ocean Winds.

Recently, researchers at the University of Limerick (UL) developed a robotic solution for inspecting floating offshore wind farms, which was tested at WindFloat Atlantic.

Mississippi River Faces Persistent Saltwater Intrusion, Region Seeks Long-Term Solutions



For the third consecutive year, the Mississippi River is experiencing significant saltwater intrusion, prompting local communities and environmental experts to search for sustainable solutions. This recurring issue arises as the river’s flow decreases, allowing saltwater to move upstream and threaten drinking water supplies. The U.S. Army Corps of Engineers is actively involved in addressing this problem, employing temporary measures like saltwater barriers to mitigate the impact on affected areas.



Saltwater infiltration poses serious risks to public health and agriculture, as freshwater sources become compromised. The situation is exacerbated by prolonged periods of drought, which have reduced freshwater flow in the Mississippi River. According to the National Weather Service, drought conditions have worsened due to climate change, increasing the frequency and severity of saltwater intrusion events.



Local authorities are collaborating with federal agencies to explore permanent solutions. Among the proposed strategies are enhanced levee systems and improved water management techniques. The U.S. Army Corps of Engineers is evaluating the feasibility of long-term infrastructure projects to prevent further saltwater encroachment. Additionally, community leaders are advocating for increased funding to support these initiatives and safeguard the region’s water resources.



The impact of saltwater intrusion extends beyond drinking water concerns, affecting local ecosystems and agricultural productivity. Farmers in the region have reported crop damage due to elevated salinity levels in irrigation water. The Natural Resources Conservation Service is working with farmers to implement adaptive practices, such as planting salt-tolerant crops and improving soil management techniques.



As the Mississippi River continues to face challenges from saltwater intrusion, stakeholders emphasize the importance of collaborative efforts and innovative solutions. The ongoing threat underscores the need for comprehensive planning and investment to protect one of America’s most vital waterways from the impacts of climate change and environmental stressors.

Environmental activists have raised concerns over the fossil fuel sector’s significant impact on COP29, the latest United Nations Climate Change Conference. Activists argue that the industry’s presence diverts focus from critical climate actions.



The conference, designed to promote global climate agreements, faces criticism for allowing fossil fuel companies to participate extensively. Environmental groups claim these companies undermine efforts to reduce carbon emissions and transition to renewable energy sources.



According to Climate Action Network, fossil fuel representatives have increased their lobbying activities, aiming to weaken climate policies. These industries allegedly influence negotiations, leading to watered-down commitments that fail to address the urgency of climate change effectively.



Experts suggest that the influence of these companies stems from financial contributions and longstanding relationships with decision-makers. Critics argue that this affects the conference’s ability to enforce meaningful climate change regulations.



During the event, several protests highlighted the need for transparency and a stronger focus on sustainable energy solutions. Activists are calling for increased participation of renewable energy stakeholders in future conferences.



The controversy surrounding fossil fuel involvement at COP29 underscores the ongoing challenge of balancing industrial interests with the global imperative to combat climate change.
