New Contracts for Jan De Nul in Australia, Russia and Canada

New Contracts for Jan De Nul in Australia, Russia and Canada

New projects with a total value of more than 500 million Euros were added to the order book of Jan De Nul Group during the past month.

The assignment for Chevron for the installation of the Wheatstone pipeline at the west coast of Australia is the largest contract. Before installing the pipeline, trenches must be dredged in the hard seabed. In order to protect the pipeline, it must also be covered with sand and rocks after installation. Furthermore, prelay rock berms have to be installed, enabling the new pipeline to cross existing pipelines.

In Canada, the Traling Suction Hopper Dredger Cristóbal Colón will execute a wellhead protection excavation in the Atlantic Ocean east of Newfoundland. This excavation will protect subsea oil installations from the impact of icebergs. The Cristóbal Colón, the largest dredger in the world, is the only dredger able to dredge to a depth of 155 m. The wellhead protection excavation is to be dredged in a water depth of 135 m.

At the east coast of the Siberian island of Sakhalin, the fallpipe vessel Simon Stevin installs umbilicals for Gazprom at 90 m water depth. These umbilicals serve to control the gas field manifolds from land. This gas field is now a priority development for Gazprom, because of an increased demand in Japan due to the shutdown of the nuclear power plants.

Further up the east coast of this island, the Cutter Suction Dredger Fernão de Magelhães is dredging an access channel for Exxon. This channel will enable to bring in barges from the sea onto the shore with modules for the onshore drill site. The Fernão de Magelhães started the works as soon as the ice had melted sufficiently so that the client can make maximum use of the ice-free season.

In the Tatar Strait between Siberia and Sakhalin, Jan De Nul Group’s rock dumping vessels La Boudeuse and Willem de Vlamingh are executing rock dumping works to protect a subsea pipeline from ice floes crossing the strait. The rocks are loaded in the Siberian port Sovgavan. The pipeline guarantees the connection of the gas fields east of Sakhalin with the mainland.

Jan De Nul Group will sail even more up to the north, in the Barents Sea near Nova Zembla. The Group will execute dredging and rock dumping works to protect pipelines which are transporting gas from the Jamal Peninsula to Western Europe.

Recently, a first project has been awarded to be executed by the Joseph Plateau. Upon commissioning, the vessel will execute rock installation in Norway at a waterdepht of 420 m for the protection and stabilisation of a new pipeline.
