Saint-Brieuc Bay offshore wind farm (496 MW): Pioneering renewable energy on the French Brittany coast

France

The Saint-Brieuc Bay offshore wind farm, with a capacity of 496 MW, is the first large-scale offshore wind project in Brittany and among the first in France. This Saint-Brieuc Bay offshore wind farm, located 16.3 km from the coast and equipped with 62 turbines of 8 MW each, will provide renewable energy to 835,000 people. IDOM has carried out the 3D modeling of the substation’s steel structure, including the jacket and all top side decks, as well as the layout of electrical, HVAC, fire protection, cable trays, and piping systems.

The offshore wind farm of Saint-Brieuc Bay with an installed capacity of 496 MW, is the first large-scale wind farm in Brittany, and one of the first in France Once put into operation by Ailes Marines in 2023, it will meet the energy needs of 835,000 people.

The 62 wind turbines, each with a capacity of 8 MW, will be configured in 7 rows. Located 16.3 km off the French coast, the farm will cover an approximate area of 75 km²

IDOM is responsible for the 3D modeling of the metallic structure of the substation, including not just the jacket foundation, but also the different levels of the topside structure (cable deck, main deck, utility deck, and roof deck). IDOM has also worked on the layout of the equipment (electrical, HVAC, fire protection, cable trays, and piping).
