Jan De Nul Group orders 30,500m³ trailing suction hopper dredger

New Vessels – July 8, 2008

Jan De Nul Group and La Naval shipyard in Bilbao, Spain, have signed an agreement for the construction of a 30,500m³ hopper dredger.

This vessel completes the present investment programme for hopper dredgers at the company, ranging from the 46,000m³ mega hoppers Cristóbal Colón and Leiv Eiriksson down to the 3,400m³ Alvar Nuñez Cabeça de Vaca and Sebastiano Caboto.

The new vessel is specifically designed for operation in shallow or confined waters, having a design draft of only 11m and a length between perpendiculars of only 161.5m.

In the design much attention has been given to efficient use of the installed power, resulting in a low fuel consumption, and lowered emissions. Two suction pipes, diameter 1,200mm, equipped with submerged dredge pumps of each 3,400kW are installed.

Double walled, electrically driven shore discharge dredge pumps with a total power of 15,000kW will enable discharging the load at a high rate, over long distances.

The company said the addition of this new vessel to its existing fleet of trailing suction hopper dredgers will enable Jan De Nul Group to offer economic solutions for any major project, even those with draft or size limitations.

The vessel will be delivered by the end of 2010. An option for a second identical vessel has also been agreed on.
