Jan De Nul is based in Aalst. Quoting the company website:

Jan De Nul was established in 1938 as a Civil Engineering and Maritime Construction Company. In 1951, expansion towards dredging started and has evolved into an important activity in which Jan De Nul has become specialized and ranks at the top.
Jan De Nul employs 2800 employees worldwide and has become a world leader in dredging, reclamation works and specialised services for offshore pipelines, rock dumping, salvage and heavy lifting. In Belgium, Jan De Nul is known for its civil engineering works, marine related civil works, buildings and water purification plants and is specialized in turnkey projects.
The Jan De Nul Group also offers large-scale environmental services which include soil remediation, confined waste disposal, sludge treatment and organic waste recycling by means of its subsidiary company Envisan.
The company owns and operates:
- 8 cutter suction dredgers with total installed diesel power ranging from 2,380 to 27,240 kW including the world's most powerful self-propelled cutter dredgers such as the JFJ De Nul, the Leonardo da Vinci and the Marco Polo.
- 17 trailing suction hopper dredgers with hopper capacities ranging from 2,339 to 33,000 cubic meters including the Vasco da Gama, the world's first mega dredger and four new trailing suction hopper dredgers launched in 2003: the Francesco di Giorgio and the Taccola with 4.400 cubic meters capacity and the 11.300 cubic meter Francis Beaufort and Filippo Brunelleschi.

Major projects include:
- The so-called "dredging contract of the century" for the reclamation of the new airport platform for Hong Kong's new international airport at Chek Lap Kok involved Jan De Nul as joint leader of an international consortium of dredging and civil engineering contractors. This massive undertaking, which was completed on time and within budget, included a total of 237 million cubic meters of dredging and land reclamation works. The project was the single largest land reclamation project at the time and employed the majority of the world's largest dredging vessels.
- The ongoing 18 year's concession contract for the deepening and the maintenance dredging of the Río Paraná and Río de la Platá in Argentina was designed to increase the navigability of the river so as to provide improved communications and trade opportunities for Argentina's inland river conurbations. This project extends over approximately 790 kilometres from the entrance of the Port of Santa Fe on the Paraná river till Punta Indio, 240 km on the Río de la Platá.
- The NorFra pipeline installation project from Draupner (Norway) to Dunkirk (France). Late in 1996 all four dredging packages tendered to Statoil were awarded to Jan De Nul. The works involved pre-sweeping over a distance of approximately 300 kilometres, pre-trenching in stiff clay at the Westhinder shipping channel and dredging and backfilling together with civil engineering works related to the landfall at Dunkirk.
- The ongoing 1,400 ha land reclamation project for housing and residential purposes at Pulau Ubin and Pulau Tekong in Singapore. Involving the filling of approx. 200 million cubic meters of sand, capital dredging of waterways, the construction of an offshore dumping ground for disposal of 24 million cubic meters of soft clays, the construction of a staging area on the mainland and bund construction works over a length of 15 km. The 5 year's project is scheduled to be completed by November 2005.

House flag of Jan De Nul

According to Brown's Flags and Funnels of Shipping Companies of the World (1995) [lgr95], the house flag of Jan De Nul is white with a red circle charged with the red letters DJN, J being bigger than D and N.
In Dutch, "nul" means zero, therefore (probably) the circle.
