Boskalis said it will earn about 200 million euros from the project, with work to start in the near future and to be executed within a period of two and a half years.
The work includes land reclamation including the construction of a breakwater and shore protection.
About 86 million cubic metres of sand will be dredged to reclaim 540 hectares of new land, to be used in part for the construction of a new cruise terminal.
DEME is a unit of Ackermans & van Haaren and CFE Group, a publicly listed civil contractor controlled by the French Vinci-Group.
