Back to efficient dredging news
On Friday 28 April 2006, the launching of the 5,600m³ trailing suction hopper dredger MARIEKE built for the Belgian contractor DEME (Dredging, Environmental and Marine Engineering N.V.) took place at the yard of IHC Holland Merwede in Sliedrecht. The launching ceremony was officiated by Mrs Jacqueline Van Bouwel-Van Ginderen, wife of Mr Marcel Van Bouwel, Area Director of DEME.
IHC Holland Dredgers BV and DEME signed the contract for the building of the MARIEKE in 2005. The construction of the vessel was subcontracted to IHC Holland Beaver Dredgers BV. The keel was laid down on 6 September 2005.
The MARIEKE is an extrapolation of the very successful 5,400m³ trailing suction hopper dredger PALLIETER that was delivered to DEME by IHC Holland Dredgers BV in 2004. A second copy of the PALLIETER, the 5,600m³ REYNAERT will be built at the IHC yard in
Kinderdijk. The construction will start in the summer of 2006 and the launch is planned for November 2006.
The MARIEKE is pre-eminently suitable for both working in shallow water, as the maintenance of ports, beach suppletion and land reclamation projects. The vessel couples a no nonsense design approach to a high degree of versatility. The economy of operation will be supported by attention to the weight and the load capacity.
The MARIEKE is a twin-screw trailing suction hopper dredger. The vessel is equipped with one suction tube with an internal diameter of 1,000mm at portside. Herewith a dredging depth of maximum 33m can be achieved.
The maximum load capacity is 8,190 tons at draught of just 7.10m. The dredged material can be discharged directly into the sea through a row rectangular bottom doors. The load can also be discharged by means of a self-emptying system, in which the dredged soil is pumped ashore through a floating pipeline, or discharged through a spraying nozzle, so-called “rainbowing”.
Accommodation has been provided for a crew of 14 persons.
