More offshore contracts for Jan de NulNews // August 8, 2012
Jan de Nul reports that new projects with a total value of more than Euros 500 million were added to its orderbook in the last month.
These include an assignment from Chevron for installation of the Wheatstone pipeline off the west coast of Australia.
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 trailing suction hopper dredger Cristóbal Colón will execute a wellhead protection excavation contract in the Atlantic Ocean east of Newfoundland. The excavation will protect subsea oil installations from the impact of icebergs.
Cristóbal Colón, the largest dredger in the world, is the only dredger able to dredge to a depth of 155m. The wellhead protection excavation is to be dredged in a water depth of 135m.
Off the east coast of the Siberian island of Sakhalin, the fallpipe vessel Simon Stevin will install umbilicals for Gazprom at a water depth of 90m. The umbilicals serve to control the gas field manifolds from land.
The 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 the island, the cutter suction dredger Fernão de Magelhães is dredging an access channel for Exxon. This channel will enable the company to bring in barges from the sea onto the shore with modules for the onshore drill site.
Fernão de Magelhães started work 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 also undertake a project even further north, in the Barents Sea near Nova Zembla.
Here, the group will undertake dredging and rock dumping work to protect pipelines which transport gas from the Jamal Peninsula to Western Europe.
A first project has also been awarded to Jan de Nul for its new fallpipe vessel Joseph Plateau. On commissioning, the vessel will execute rock installation in Norway at a water depth of 420m for the protection and stabilisation of a new pipeline.
