Happy New Year! First of all, I would like to wish you: health, happiness and a year full of dredging action. And there will certainly be some dredging action. We will start this year with closing our ¡VAMOS! project and we will close off with another CEDA Dredging Days1, just as with which this blog started one year ago with a new year’s resolution.
Further topics will include the upcoming WODCON conference in Shanghai2, more CEDA Dredging Management Commission, some interesting book reviews and whatever happens along the way. Maybe I can get back on working on articles that explain interesting phenomena in dredging technology. Or just some funny experiences I had in our beautiful profession. There are so many memorable moments worth sharing for the general benefit.
And George Santayana has warned us to learn from the past: ‘Those who cannot remember the past are condemned to repeat it.’3 I don’t fancy that this site will be a monumental source of reference for posterity. There are much better institutes to store and share dredging knowledge. e.g. the CEDA comes to mind. It’s ‘a forum for all stakeholders involved in the dredging industry’4 and there are many working groups were the current knowledge is shared and stored in publications.
A much better place to look at a condensation of knowledge over a longer time span is the National Dredging Museum5. You might have noticed, that I am very fond of museums. I like to dwell through their expositions, relive the past and see the origins of current technologies. When I am trying to hatch some new sort of gizmo or gadget to perform a very peculiar dredging requirement, I can relate to all those branches of the technology tree, that are out there and see if there is something that can be combined in a new contraption.
Sometimes you can recognize some technology in an exhibit, that was ahead of its time. Take this ‘Krabbelaar’ or ‘Scratcher’. It loosens the top layer of the sediment and expected it to flush out at the outgoing tide. Considering the enormous forces for cutting and internal friction, that have to be delivered by sail power, I doubt the production would make a viable business case. Nowadays, you would employ a dredge plough behind a tug6. Modern propulsion delivers the thrust needed for all requirements. Ploughing, scraping and smoothing has become much easier and modern hydrological simulations will give a better idea about the possible production and where the sediment will end up.
Possibly our modern dredge plough technology will be surpassed by even better concepts. Maybe, regulations or fuel economy would direct us back again to a sustainable form of dredging management and the old scratcher makes a comeback in a modern form. And then, you know to find the origins in the National Dredging Museum.
I think, it is very important, we cherish our dredging heritage. For ourselves and for our posterity. Just as we support our trade associations, we should support the dredging museum. So, now I come back to my ‘new’ new year’s resolution: I will become patron7 to the National Dredging Museum. It is not much, but if it inspires you to do the same, we can make a difference together.
