The DEME dredging fleet: strong in every segment
We own and operate a fleet of over 80 main dredging vessels and additionally another 200 auxiliary vessels and specialised equipment. Versatility is a basic characteristic of this extensive fleet that is strong in every segment : in types and in sizes. This fleet is maintained, upgraded and modernized on day-to-day basis. Considerable investments have been made and are being planned to further expand our fleet. Between 2002 and 2007 ten new dredging vessels have been built and added to our fleet. A new investment plan for another ten new dredging units is being prepared at this moment. DEME has always been a trend setter in the design and development of new dredgers and dredging techniques and tools on board our vessels. The latest revolutionary improvement on trailing suction hopper dredgers, developed in-house for the three latest vessels (Marieke, Reynaert and Breydel) is the one-man operated bridge. |

DEME owns more than 20 trailers, ranging from over 24,000 m3 capacity to 1,750 m3 capacity. This allows every flexibility in the execution of both capital and maintenance dredging works. 
With almost 20 major units, we own and operate an extensive cutter fleet. Among them is the strongest cutter dredger ever built, the “D’Artagnan”. This is a self-propelled 38,000 HP seagoing mega rock cutter. 
A backhoe dredger is based on the giant land-based backhoe excavator that is mounted at one end of a spud-rigged pontoon. Its main advantage is its ability to dredge a wide range of materials, including debris and soft, weathered or fractured rocks. The “Pinocchio” is our biggest one. It has an installed power of 2,600 kW.
This is one of the oldest types of dredgers, the functions of which have been taken over in time by the newer dredger types. It is still used sometimes for accurate trench dredging and for environmental applications.
DEME operates 2 vessels with Water Injection Dredging capability. In specialised but frequently occurring circumstances this dredging techniqus presents a very economical solution, requiring only a very limited amount of energy, making it an environmental high-flyer.
DEME operates four vessels with Plough Dredging capability. In specialised but frequently occurring circumstances this dredging technique presents a very economical solution, requiring only a very limited amount of energy, making it an environmental high-flyer.
Is to be considered as a useful auxiliary vessel that is filled by other dredgers with any type of dredged material, from silt to rock for transport to a discharge area.
This high-tech and highly automated pontoon is used for accurate spreading of for example dredged gravel onto the seabed to serve as foundation for the construction of breakwaters.
A fallpipe vessel drops rocky material into position using a fallpipe system that is installed midships. The vessel is dynamically positioned (DP). The stone is pushed into the fallpipe on board the ship as the ship sails over the place where the stone has to be placed. The end of the fallpipe is only a few meters over the pipeline or structure to be protected or stabilised and it is positioned precisely using a remotely operated vehicle (R.O.V.). Precise stone dumping is therefore possible to depths of 1,000 m.
This vessel transports rock and dumps it by a sideways shifting process in order to protect oil and gas pipeline approach areas or for erosion protection.
This is a crane-mounted pontoon that allows the marine lifting and precise placement of heavy structures as well as the removal or salvage of ship wrecks, etc.
These jack-up pontoons allow marine hydraulic engineering and salvage works in deep waters offshore for the installation of any type of offshore structure, such as wind farms or weather stations, etc.
