In July 2007, Jan de Nul Group and La Naval Shipyard in Bilbao, Spain, signed an agreement for the construction of a 30 500 m3 trailing suction hopper dredger. The new vessel is specially designed for operation in shallow or confined waters, having a design draught of 11 m and a length of only 161.5 m. In the design much attention has been given to efficient use of the installed power, resulting in low fuel consumption and lower emissions. Two suction pipes, diameter 1200 mm, equipped with submerged dredge pumps of each 3 400 kW are installed. Double walled electrically driven shore discharging dredge pumps with a total power of 15 000 kW enable discharging the load at a high rate, over long distances.
Jan de Nul awarded the contract for the main part of the basic design to Vuyk, comprising of the following scope of work:
- Main construction drawings of the hull and superstructures, including all foundations for the dredging equipment.
- FEM global hull strength analysis.
- Arrangement drawings (i.e. engine room).
