DensiTune promises dredger deployment savings
Dutch Dredging BV has acquired the system for coastal research of mud bank migration
Stema Systems launched the newly developed DensiTune at OI2014 in London last month.
This latest member of the Tune product range further enhances the portability of systems intended for in-situ density and yield strength profiles in fluid muds. The launch at Oceanology International was in fact preceded by deployment in French Guyana.
Dutch Dredging BV from the Netherlands has acquired the system for coastal research of mud bank migration and proving the nautical depth in the adjacent access channel. Insight in the density gradient enables better planning for the deployment of dredging equipment and can lead to significant cost reductions. The Tuning fork principle has gained wide acceptance and is in use in several harbours around the world. Both the US Army Corps of Engineers (USACE) and the Hamburg Port Authority have recently acquired complete systems to manage the nautical depth maintenance works.
A Fluid Mud Workshoptitled ‘Fluid mud in ports and navigation - management today and in the future’ was held at the OI2014, organised by HR Wallingford. It addressed aspects related to mapping the nautical depth when standard echosounders do not provide the complete picture. Among the speakers was Mark Burrows from the Bristol Port Authority, who discussed the use of Tune probes in combination with the Silas acoustic density mapping system.
