The new Forme 10 drydock in Marseille will open for business next week.
The facility, operated by Chantier Naval de Marseille (CNdM), is the biggest dock in the Mediterranean, the company said.
It can handle vessels of more than 270 metres in length due to its measurements of 465 metres by 85 metres.
The first job is maintenance on an MSC cruiseship, which will be followed by two Costa Cruises vessels at the end of November.
