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 build-up of shells and seaweed, Reseau de Transport d’Electricite (RTE) said. These issues must be tackled before floating wind can succeed on a large scale and RTE is among operators trying to fix them...
