Croatia: Jan De Nul Launches New Suction Hopper Dredger

Jan De Nul Launches New Suction Hopper Dredger

Last Saturday 14 July at 11h30, the Trailing Suction Hopper Dredger ‘Bartolomeu Dias’ was launched at Uljanik Brodogradiliste d.d. shipyard in Pula (Croatia). The ‘Bartolomeu Dias’ is a sister vessel of the ‘Pedro Álvares Cabral’ that was launched in the beginning of this year, also at this shipyard in Pula.

After the successful investments between 2007 and 2011 amounting to more than 2 billion Euros, Jan De Nul Group decided to add 3 more vessels to the fleet. These two Trailing Suction Hopper Dredgers with a hopper capacity of 14,000 m³ each and the fallpipe and mining vessel ‘Joseph Plateau’ that will be launched on 3 August 2012 at the shipyard Construcciones Navales del Norte near Bilbao in Spain.

JAN DE NUL IS LOOKING FOR TECHNICAL PERSONNEL AND CREW MEMBERS

In the meantime, Jan De Nul Group continues its search for technical personnel and crew members. Recently, Jan De Nul started a huge HR campaign in cooperation with Kamagurka, a Belgian cartoonist. The key role players in this campaign are his cartoon figures ‘Bert en Bobje’, very well known in Belgium.

The Group does not only need new talent to man these new vessels, but also the sites worldwide.

NEW OFFSHORE CONTRACTS IN AUSTRALIA, RUSSIA, CANADA AND THE BARENTS SEA

New sites 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 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 excavate a Glory Hole in the Atlantic Ocean east of Newfoundland. The Glory Hole will protect subsea oil installations from icebergs. The ‘Cristóbal Colón’, the largest dredger in the world, is the only dredger able to dredge to a depth of 155 m. The Glory Hole is to be dredged at a water depth of 130 m.

At the east coast of the Siberian island of Sakhalin, the fallpipe vessel ‘Simon Stevin’ will install 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.

And finally, 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.
