https://www.optimum-te.com/wp-content/uploads/2025/02/calvados-1.jpg5003572021 was rounded off in great fashion as OPTIMUM accompanied RTE in the successful completion of the trenchless drilling section of the Calvados offshore windfarm project on the Normandy coast. No less than 5 dual HDD crossings, from 100m to 430m long, were drilled through Caen limestone to carry the 225 kV cables under 2 roads, a dual carriageway, a canal and the river Orne. This trenchless section is a key step in connecting the offshore wind turbines to the electricity substation.
