CEDA DMC Presentation On Dredging Innovations In Gdansk

Because of other activities these last weeks, my promised post about the DMC presentation had some delay. On October 10th, there was a symposium together with the Marine Institute Gdansk and the CEDA Environmental Commission and the CEDA Dredging Management Commission supported by Gdansk Science and Technology Park and the Baltic Ports Organisation1. The topic of the symposium was ‘Advances in Dredging Technology. My contribution was a presentation as DMC member2 on ‘Dredging technology developments versus requirements’.

Although dredging sounds like an old rusty trade, in fact, it is in constant movement and highly innovative when experienced from the inside. At the Dredging Management Commission, we have a separate focus group, that investigates the technological solutions that enable the stakeholders to efficiently manage a dredging project. A lot of ‘booby traps’ in the ‘Checklist For Successful Dredging Management’3 can be handled by applying the right technology. If there are issues with turbidity, e.g. one can apply a component as the ‘Plumigator®’4 attachment for the overflow in a trailing suction hopper dredge to comply with turbidity clauses in the contract. If the project has very narrow allowances for positioning, modern survey and control systems allow surgical precision dredging, to reduce overdredging and corresponding penalties.

All in all, we’ve identified more than 70 innovation over the last ten years, that have found a foothold in the dredging industry. These have been categorised to the field of technology: Components, Equipment, Industries, Initiatives, Methodology, Processes, Systems, Tools. Other descriptions that we’ve attributed to these innovations were their contribution in solving certain problems in dredging management, as they are found in the checklist. And how much effort they require and how much benefit they would yield. These last items are very subjective and still open for debate. More to follow later. But, at least the procedure can be laid out to recommend the best options for tackling certain problems in the ‘checklist.

We had a good discussion at the symposium about this topic and from the other focus groups (contract management, checklist, etc.). There were also cross-over opportunities with the CEDA Environmental Commission. At least, there are enough leads, that can be used for the next CEDA Dredging Days in Rotterdam.

As an illustration of the long way we’ve came in the dredging industry, the conference room in the control centre of the Port of Gdansk5, was decorated with interesting pictures from the construction of the port.
