Customer feedback is keySince its creation, we have been receiving valuable customer feedback about the Plumigator® overflows functionality. While successful in limiting air release and turbidity during dredging, offering environmental as well as economic benefits, the Plumigator overflow was not without its own challenges. In some challenging projects the dredging process needed to be halted due to debris clogging up the gratings which cover the water inlets. The gratings, which are meant to keep out large foreign objects, collected tree stumps, sea grass and lots of plastic debris.
Reducing overflow blockagesEasy cleaning and maintenance of the Plumigator® overflow was crucial to ensuring uptime in dredging operations. But how could we best ensure that the overflow would not clog and that cleaning could be done in a safe and efficient way? By adjusting the inlet opening sizes and making part of the overflow moveable.
Optimising the inlet opening created a larger passage for debris and further reduced the need for grating. Making the insert moveable ensures the release of yet collected debris and ease of accessibility for maintenance and inspection. Both ultimately improve uptime as operations no longer need to halt for lengthy, costly and sometimes tedious maintenance work.
The patented design of the inlet openings also reduces the velocity of excess water in the hopper. This is beneficial as it allows the soil particles extra time to settle. Combine this with the decreased weight of the construction an increase in production by reduced loading time and increased payload is created.
