World's Largest Offshore Gantry Crane for Reunion Island Highway
Zourite jack-up barge with Enerpac overhead travel crane for Reunion Island project.
The world’s largest offshore overhead travel crane developed and manufactured by Enerpac, mounted on the Zourite jack-up barge, has gone to Reunion Island, located East of Madagascar in the Indian Ocean.
The Enerpac Over Head Travel Crane (OHTC) comprises two pairs of lifting beams, with an overall width of 30 m, and a lifting capacity of 4,800 tonnes for lifting, moving and lowering the concrete blocks for the offshore highway.

The French consortium Bouygues Travaux Publics, VINCI Construction Grands Projets, Dodin Campenon Bernard and Demathieu Bard Construction are constructing a 5,400 m bridge for a new offshore highway in Reunion Island. It replaces the existing coastal road, which is exposed to falling rocks and flooding from swells and tropical storms.
The Zourite jack-up barge was transported to Reunion Island aboard the Offshore Heavy Transport’s Hawk semi-submersible vessel, and it arrived in June.
The 5,400 m coastal highway (Route du Littoral) will connect Saint Denis - the administrative capital of La Réunion - with La Possession. It replaces the existing coastal road, which is exposed to falling rocks and flooding from swells and tropical storms.
The Bouygues Travaux Publics, VINCI Construction and Demathieu Bard Construction consortium has built a barge to construct the offshore highway. Enerpac is supplying the gantry crane with 4,800 tonne lifting capacity for the barge.
The barge will be used to pick up concrete precast foundation elements (gravity base, pile head and segments) at the harbor of Reunion Island, and position them on the seabed. The Enerpac offshore crane will be used to make at least 200 foundation block lifts.
Global director Enerpac Integrated Solutions, Jeroen Naalden, commented:
We are delighted to have the opportunity to work with Bouygues Travaux Publics, VINCI Construction and Demathieu Bard Construction on this important infrastructure project. With a history of being involved in the Kursk salvage offshore, the Millau Viaduct construction and other significant heavy lifting operations, we have a growing reputation for excellence in bespoke heavy lift systems.
