Jan De Nul Group has executed a numerous number of projects world-wide for which we refer to the enclosed reference list. The Company has proven its technical and financial strength for a number of massive undertakings of which some examples are shown below.

1. Jan De Nul Group is executing a 18 year dredging and maintenance dredging contract of the Paraná and la Plata River in Argentina. As a result of the better navigability of the river, the Argentine hinterland has revived considerably. This project extends over approximately 790 kilometres from the entrance of the Port of Santa Fe on the Parana River untill Punta Indio, km 239 on the Rio de la Plata and is executed over an 18 years concession period.

2. In October 2000, Jan De Nul Group together with its Japanese partner Toa, was awarded the contract for the 1,400 ha land reclamation project at Pulau Ubin and Pulau Tekong, Singapore. This massive project for housing and residential purposes involves the filling of ca. 200 million m³ of sand, capital dredging of waterways, the construction of an offshore dumping ground for disposal of 24 million m³ of soft clays, the construction of a staging area on the mainland and bund construction works over a length of ca. 15km.  The project is scheduled to be completed by 2009.

3. Jan De Nul Group was awarded the prestigious project Palm Island Jebel Ali called Palm Island II in Dubai in 2002 and finished the works by the end of 2006. The reclamation project Palm Island II holds the creation of a 4 km long peninsula in the form of a palm tree, protected by a 200 m wide and 17 km long breakwater built around the island. 135,000,000 m³ of rock, sand and limestone were reclaimed (partly originating from the Jebel Ali Entrance Channel dredging works). Also the slope protection works for the crescent were undertaken by Jan De Nul Group. The artificial peninsula is protected from the actions of the sea by approximately 5,000,000 m³ of rocks.

4. The reclamation works on the first seven islands of the multi billion dollar Waterfront Project in Dubai, covering 2,300 hectares and involving more than 300 million m3 of sand and 12 million m3 of rock for protection against erosion. This project, mainly executed by Trailer Suction Hopper Dredgers, will take approximately six years to complete. The first island will take 18 months to construct.
