Floating wind energy projects could open up vast areas of the world’s oceans to produce carbon-free power. But developers must first solve two key technical problems, according to France’s electric-grid operator.
Sea swell can cause vibrations that harm floating-substation equipment, while cables can be damaged by a buildup of shells and seaweed, Reseau de Transport d’Electricite said. These issues must be tackled before floating wind can succeed on a large scale, and RTE is among operators trying to fix them.
This nascent segment of the clean-power industry would significantly expand the potential areas of the sea where energy producers could install turbines. In many places, the best wind resources are in waters that are too deep to build a structure from the seabed. But the new floating technology is expensive and at risk of damage from waves and sealife.
Wind Power Giant’s Profit Hit by Rocks on the Seabed
Building power plants in the middle of the sea was never going to be easy.
The world’s largest developer of offshore wind farms Orsted A/S has found that some of its cables connecting to wind farms have been damaged by scraping against rocks on the seabed and will need to spend as much as 3 billion Danish kroner ($489 million) to fix them. It’s part of the growing pains for the offshore wind industry that’s become one of the fastest-growing sources of electricity.
Offshore wind farms involve a network of turbines with cables that connect to shore and into the power grid. The open seas provide stronger and more consistent wind speeds than on land.

GE Renewable Energy will create as many as 750 new jobs in northeast England with a new factory that will make hundreds of giant blades destined for wind turbines in the North Sea.
The new facility, located in Teesside, is set to open and begin production in 2023, the company said in a statement.
The GE announcement was made on the same day the U.K. government confirmed plans to invest 95 million pounds ($132 million) to create two dedicated offshore wind ports in Teesside and on the Humber, an estuary also on the U.K.’s northeast coast.
