The Last Dredging And Port Construction Magazine, The End Of An Era

The last issue of Dredging and Port Construction
The last issue of Dredging and Port Construction

It is not very often that one experiences the end of an era. Hiroshima, the fall of the Berlin Wall, Brexit. Those were very important events with a global impact. Now there is another end of a period, with only a limited impact on a small community affected. After half a century, our trusted journal ‘Dredging and Port Construction’ has come to an end1. In the fast moving media world, this will only be a footnote in history. Yet, as a magazine, it was close to our community. It reported on projects and people we knew, but also as a platform for the CEDA to communicate with us for 42 years2.

IHS Markit has decided to cease this publication, the lack of new subscriptions and decreasing advertisements. You know, the general malaise in paper printing. Somehow, the digital revolution didn’t turn out so well for them. Other digital media providers covering the dredging industry seem to have a better business model to survive the transition. Right?

Well, there is a big disadvantage of those free service, hot shot, social media savvy new comers, they just forward press releases that they receive or sweep up from social media. They don’t have dredging literate expert editors writing long genuine articles about topics that would not have access to coverage by themselves. Having your own knowledgeable editors doing original research vetting the facts and reporting from a broad perspective with a solidly founded opinion is expensive. And that makes it very difficult for a classic publisher to survive in these modern times.

We will suffer in this new era without our trusted DPC. We can sign up to the usual free subscription daily newsletters from the new media publishers and read the endlessly repeating press releases. We will miss the in depth reports on big projects or critical comments on regulatory issues. We will have to figure this out from within our own social media bubbles. It will narrow our view and I certainly hope we don’t lose the perspective of other members in our community.

Please be advised, that also the website will be closed at the end of June3, leaving only the digital archive of the magazine accessible4, which goes back to May 2015. Although the last editor, Ines Nastali, told me she is happy to send out articles if requested by the dredging community. There will only be some dusty old paper versions that are stored in a forgotten archive or that one issue we keep for some sweet memory. At least that is what I have done. Over the years, I have written several articles that have been placed in this magazine and I cherish those issues. The first one was already long ago about a CEDA excursion to the IJsseloog in the Ketelmeer project. The last one was a reprint from my post5 about energy transition in the dredging industry discussed during the CEDA Dredging Days6.

It was a good experience to contribute to the magazine that way. And made me proud, that my posts at this website were picked up by the media. I will see what will come along in the future. I am open to any opportunity. At least, I am determined to keep www.discoverdredging.com alive as an independent platform to point out dredging related topics. And this will be a lonely place left to find an opinion about our community, albeit, very personal.

Although we are an industry in an economic sense, it is a community. When I think of companies and projects, I think about the people I know over there. And my memory about Dredging and Port Construction will not only be the magazine, but also the nice cooperation with the editors. At this moment I would like to especially thank Tony Slinn, Lisa Maher and Ines Nastali for a their work.

Paying Tribute to the Hard Life of Peat Dredgers

Sculpture ‘Verveners’ by John Rijnen
Sculpture ‘Verveners’ by John Rijnen

It’s been a while since my last update. Don’t worry. All is well. The delay was due to my change in habitat. Moving can be draining attention and creativity, but can also create opportunities for exploring the new neighbourhood. And that is exactly what I will share as this first post. One of the first dredging related discoveries was a sculpture on a roundabout nearby. Probably most passers-by will not notice it or at most will be puzzled by the strange flat figures. To us, as dredging community, we immediately recognise the typical posture of manual dredging. Intrigued by the unexpected discovery of dredging art at this location, I went on an investigation on the background of this statue.

The sign at the sculpture did reveal some details on the name, date and artist of this monument1. Obviously, the topic of this statue was a tribute to the people who have been working as peat dredgers and contributing to the wealth of the town. It is also a reference to the origin of the current geography of the municipality: lots of lakes and ponds that are a recreational area for the population and a resting place for nature, that were unbelievably all excavated manually over ages.

The most characteristic feature of the sculpture are long poles2 in combination with the posture for back breaking manual labour. The long pole has a hoop at the lower end with some kind of fishing net attached. The hoop is used to scrape sediment (in this case peat) from the bottom and collected in the pouch. Mud and peat are sticky enough to stay in the net for vertical transport, but the flexibility and openness enables easy discharge. For peat dredging the material was scooped up on shore and dried3. For maintenance dredging, the material was brought on board and discharged at a convenient disposal location4. The Dutch dredging industry cherishes this and remembers it with all kinds of small statues found in many offices.

Manual dredging shaped much of Holland’s geography, either the canals and lakes or the reclamation of marsh into pasture land. It has been identified as a typical Dutch tradition. But is it?? Preparing this post, I’ve discovered it is not. Several references say that we did not invent the ‘baggerbeugel’2. Before we started to use it, it has been applied already for ages in East Anglia5, which had a very similar landscape. Already from the tenth century, peat has been excavated from the Fenlands and later on from the 14th century, they started manual dredging already. Only later on in the 16th century Holland started to take over this practice. And in good Dutch tradition, we refined the trade and even exported consultancy on these projects back to England!

Peat dredging is a laborious procedure and later on, this industry was mechanised. There is a nice video explaining about peat dredging in the Netherlands. Especially the hydraulic dredging starts at 08:10 into the video. All processes in a regular dredging project are identifiable: a) dredging, b) discharge, c) bulldozering, d) compacting, e) drying and f) further transport of the merchandise.

Viewing a video is one way to experience manual dredging. In the dredging garden of the National Dredging Museum6, there is an exhibit to experience this trade first hand.

Happy 2019!

Post card picture of a Damen CSD500 at work.

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.

Model of a ‘Krabbelaar’ or ‘Scratcher’ at the National Dredging Museum.

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.

Example of a modern dredge plough, fitted on a Damen Stan Tug 1606.

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.

Collection of dredges.
