World’s largest offshore overhead gantry crane to be built by Enerpac

Enerpac is to build what it claims will be the world’s largest offshore overhead gantry crane.

The 4,800t lifting capacity crane will be based in Indian Ocean and used for the construction of a coastal highway on the Indian Ocean island of La Réunion.

It will install precast viaduct columns as part of a project run by French consortium Bouygues Travaux Publics, Vinci Construction and Demathieu Bard Construction. A special jack-up barge will be built to construct the offshore highway. The crane will help position elements on the seabed, including at least 200 pieces of foundation block.

The crane will be used as part of the construction of a new 5,400m coastal highway called Route du Littoral. It will connect the administrative capital Saint Denis with La Possession. It replaces an existing road that is vulnerable to storms.

Enerpac director Jeroen Naalden said: “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.”

    The Oosterschelde works in Holland in the 1980's used Ostrea, a ship capable of lifting a concrete pillar from the dry dock and placing it accurately on a special foil on the seabed. The ship was85 metres long and has a portal of 50 metres high. The ship could only lift 10000 tonnes, but as a large part of the pillar was underwater, it was not necessary for the ship to be able to lift the full 18000 tonnes.
