Dear readers, I sincerely wish you all the best for this new year. As things are looking positive on the vaccine front, we should keep testing negative this year. There are lots of items and events to look forward. Last year was not quite what we’ve hoped for and wished each other.

I do hope all of you are OK and are still together with your loved ones. I am fortunately in that respect. So, next to the Covid situation, there were a lot of other noteworthy items. Most of them have been featured here on Discover Dredging. My trip to Bangladesh, just before all the lockdown measures. The graduation of Carsten1 and Omar2 that were completely over Teams. Some attention to our Damen Dredging Experience3. And some other items. Did you enjoy the Donald Duck review?4

One sad event was, the last issue of Dredging and Port Construction5. We’ve had to say goodbye to our trusted DPC. Although by now, there has been a kind of digital revival on the CEDA Website6. They opened up a section for Industry News, edited by Namrata Nadkarni. It stands out from the other online media covering dredging as there has been some attention to smaller topics, that would normally not get covered. As I think it is a good initiative, I urge you to subscribe and also participate by sending them any noteworthy news items for publication. Not specifically the usual company press releases, but also the more thought provocative opinions and perspectives on the activities of our dredging community. Active participation could make this CEDA Industry News flourish this year.

Further personal activities within CEDA are the Dredging Management Commission7 and I am looking forward to the exciting new concept for the CEDA Dredging Days8. Will you participate? Also, I already took the course on ‘Dredging for Sustainable Infrastructure’9, but you should keep an eye out on the next instalment, coming soon10.

A continuation from last year on my Discover Dredging will be some more articles on our Damen Dredging Experience. There are still some exhibit left to review and teaser:… There are some new exhibits arriving! Hope to have that covered when the pandemic will fizzle out we can show you around through our museum. And I hope to continue on pump and dredge technology.

Currently, there are some students working on their graduation thesis. Their very interesting topics will be highlighted here as well. Some others will start soon. When you are looking for a fun place to have your internship our your graduation, you might consider a visit to our career page11 or contacting Frank Bosman for any opportunities. Although most positions are filled at the moment, later this year we would welcome fresh brains again.

As our offices will be closed for regular work, I will be working from home most of the time. Probably most of you will do likewise. To keep track of the passage of time over the days, you should have a calendar. As a special service to my audience, I was granted the use of a set of beautiful pictures to create a calendar. You can download the file here and with some DIY skills you should have some original wall decoration for this year.

Stay healthy and stay safe. Hope to see you later this year.

How A Ship On The Shore Became a Beacon For My Dredging Career

Long ago, we were sailing with my parents and my brother into the Venezuelan archipelago of ‘Los Roques’.1 After clearing customs, we learned that there was another sailing vessel in trouble. It was stranded on the reefs at the east side of the islands. As we had some spare time we decided to lend a hand in getting them afloat. By eyeball navigation through the channel behind the coral reef, we found the stranded English catamaran ‘Yo’, but had to anchor 200m away. First we learned from a Swiss captain on another assisting yacht they had been pulling together with a maxi yacht on a long hawser to pull them off by power and sail. Alas, to no avail.

The next day, the swiss captain had to leave and we undertook the journey by dinghy to visit the crew on ‘Yo’. It turned out to be a couple with their son and two deckhands. They told us that the maxi yacht was ‘Drum’2 and one of the crew was no other than rock star Simon Le Bon3 himself. We just missed them by a day! He did all the best to cheer them up and you can image what a support that visit meant to these people in such a desperate situation.

As my dad was a chief engineer from the merchant marine, he surveyed the damage professionally. ‘Yo’ was sitting exactly on top of the reef. One keel was broken of and the other only half, but was sheared below the wreck and stuck between the coral heads, preventing any movement. After evaluating the state of the boat, the equipment and the location, he actually said: ‘We’re gonna science the shit out of this.’4 Together we devised a cunning plan:

  1. Lift/Float: Remove the rest of the keel. Plug the holes left by the bolts and increase buoyancy of the craft.
  2. Dredge: Lower the rock bottom to increase support from the buoyancy and create a channel to freedom.
  3. Move: Assemble all winches and tackle to leverage the pulling forces. The forces would be so high that we feared we would pull the catamaran in half. So we had to distribute the forces all around the hull.

The structural repairs on the hull were performed by my father. My brother and me were in charge of the winches and tackle. Any spare time was dedicated to cutting the rock below the wreck. For sure, that is a nasty job, we tore our clothes and cut ourselves on the sharp edges of the coral. By practice, I learned the different angles to aim the pickaxe for the best results and the lowest effort: an introduction into Specific Cutting Energy!5 Because we did our calculations careful and our assumptions were right, the boat moved exactly the moment we predicted and in the way we wanted. It was a great moment of revelation: you could actually use all this knowledge from physics classes6 to get you out of a nasty position. It set me on a path where I am now and you are reading this story.

Actually, we did not see them completely get off, as we had other obligations and had to leave. We were confident they would come off, but it was a mystery to us where they did end up. Finally after thirty years, I did a Google search and to my surprise I found they did get off indeed and were even reunited with their first rescuer, Simon Le Bon.7

That was my own story on dredging and salvage. Currently, there is an interesting exhibition at the National Dredging Museum8 with better documented cases and very interesting displays. Still, the three steps used for ‘Yo’: ‘Lift, Dredge and Move’ can be distinguished for the other cases there, also.

Remarks

Please keep in mind, that these events happened more than thirty years ago and were about saving the lives of five people in immediate danger. Dredging in coral should only be done under very strict conditions with the health of the ecosystem in the first place and in balance with the necessity of the operation.

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.
