Chantier Naval de l'Océan Indien

Located in Port Louis, Mauritius’s capital, CNOI Shipyard (Chantier Naval de l'Ocean Indien) is one of the leading ship-repair and ship-building yards in the Indian Ocean. Mauritius is situated at a strategic point, whereby the island figures on the route of various merchant navies. The island is close to significant fishing grounds as it lies in the middle of the Indian Ocean and the Antarctic Ocean.

For several years, CNOI has been working on a major expansion project. This began in 2019 with the acquisition of more than one additional hectare, increasing the working area from 4.5 to 5.6 hectares. A reorganization is therefore underway with the creation of new workshops:
- New construction workshop of 1400m2
- Heavy mechanical workshop of 410m2
- Electrical/Refrigeration workshop of 380m2
- Workshop and storage insulation of 200m2
- Storage warehouse with approximately 2000 pallets

A new sheet metal yard has also been created, the shops and storage warehouses have been extended, new offices were built for the administration’s personnel as well as for the shipowners. This project has been marked with the acquisition of the world’s biggest mobile boat hoist. During the second trimester of 2020, CNOI has ordered an elevator of 1500t with the Italian company CIMOLAI. This new lifting tool, commissioned in November 2021, replace the older synchrolift, and allows up to 5 ships to be dry-docked simultaneously on the new berth.

The shipyard


CNOI is the "one-stop shop" for ship repair in the Indian Ocean. Ship owners who come to the shipyard to make their technical calls benefit from the advantages offered by Mauritius: supplies, air and sea services and the facilities of the "seafood hub".


The shipyard is used to accommodate tuna purse seiners with a storage capacity between 700 and 2200 tons and a length varying between 70 and 115 meters.

French Navy

Several years ago, the CNOI signed a contract with the French Navy for the maintenance and repair of its frigates based in Reunion Island.


New ship building represents a significant part of the activity on the shipyard. Thanks to international quality standards and working in accordance with the requirements of ship classification societies (Bureau Veritas, APAVE...), the CNOI's clients are mainly French (based in Reunion Island and Mayotte), Madagascan, Australian and Mauritian.

Since the creation of the site

31 ships left the CNOI workshops. Two other achievements have marked its history. A total overhaul of a 39-meter aluminum passenger ship (Mayotte), the jumboization of a longliner, with an 8.2-meter extension (Australia).
