In dredging, the hydraulic transport of solids is one of the most important processes. Since the 50’s many researchers have tried to create a physical mathematical model in order to predict the head losses in slurry transport. These models are Durand, Condolios, Gibert, Worster. Zandi & Govatos, Juf
Autorità Portuale di Piombino seeks contractors for the detailed design and implementation of infrastructure projects to promote industrial competitiveness in the Port of Piombino.

Dublin Port Company has announced a plan for the development of its deep water berths. Part of the river Liffey at Dublin Port will be dredged to create a 12m deep channel for some of the world’s biggest liners, up to 340m long, to dock beside the East Link toll bridge. The development will be [&hel
Ardersier and Petty residents had the opportunity recently to find out more about the Port of Ardersier’s ambitious plans to develop the former oil yard. Alastair Wood, of Savills property consultants, which represents site owners the Port of Ardersier Ltd, gave a brief presentation and answered que
In recent years, Chinese dredging companies have been actively taking pail in the domestic and foreign dredging market. They have built a large numbers of cutter suction dredgers, CSDs & trailer suction hopper dredgers, TSHDs with the Chinese dredging equipment makers developing and improving a lot.
When dredging hard cohesive soils such as clayey silt, mild clay and clay, traditional teeth such as chisel teeth can only penetrate to a shallow depth of the soil layer and bear more cutting resistance, which directly affects the dredging efficiency of the trailing suction hopper dredger. In order
Every three years leading experts meet for the World Dredging Congress and Exhibition (known as WODCON), the single most important event for the world wide dredging community to discuss the latest developments of their profession. In 2013 this major gathering took take place in Brussels, Belgium. Th
REMU Big Float is a unique amphibious excavator for the most challenging environment like swamp, shoreline, waste ponds and canals. Patented pontoon undercarriage that can be narrowed, enables easy transportation along public roads. REMU Big Float is instantly ready to use without any assembly at th
The hydrocyclone is equipment for solid-liquid mixture separation. It can be used to both separate and concentrate dredged material. When a Trailer Suction Hopper Dredge (THSD) dredges material consisting of fine particles, the material can’t settle quickly in the hopper leading to an overflow-loadi
Van Oord’s powerful cutter suction dredger Athena was built by IHC Dredgers for dredging in hard soil. The strong vibrations on this type of dredger are notorious for their negative effects on the working and living conditions on board. Van Oord’s global dredging experience, IHC’s drive to build inn
