The most common reason for low production rates is the excavation rate. Based on the soil data, an excavation production is expected for a specific dredger. But during the execution of the job, the actual production can be lower than expected. In most of the cases, this will be in soils that are very unpredictable - and therefore difficult to quantify during tender phase:

​

• dense to very dense soil types such as glacial till and dense fine sand

• cohesive hard soils

• soils containing boulders or boulder sized obstructions

• different soil types interacting in a negative way

​

What can we do for you in this case?

​

• if datalog files are available: make a quick office-based assessment of the problem and possibilities to tackle it

• go on board to get a better view on the problem and try to solve it by implementing structural changes on the dredging head, mostly small and quick changes on board or local workshops

• look for production improvement through adapted way of dredging

• if the problem is recurrent for the dredger or company, design a custombuilt head for higher efficiency of the dredger on future similar jobs

• write a report about the problem and solutions that can be used for continuous improvement
