![]() This looks pretty simple, but it is a phenomenal innovative design. Here you see such a reduction gear (on the right), on the left, you see an e-motor that provides power as well. This also means you need a reduction gear in between the engine and the propellor (shaft) to reduce the propellor RPM. On many ships these days we see so-called four-stroke medium-speed engines. On the very very large two-stroke engines, the propellor is coupled directly, via a propellor shaft to the engine. On merchant ships for best efficiency, the ship propellers can't be turning too fast. They are also big in the maritime industry providing all kinds of very fancy and huge reduction gear. Petrolheads will recognize the name of this company, ZF. One of my favourite models I came across was a very smart model of a powerful harbour tug. They have to be taken apart and each plate has to be cleaned individually. Especially if you operate in shallow waters or river estuaries you might end up with a lot of mud inside these things. We used them to cool the engine cooling water (freshwater) with sea water (salt water). These so-called plate coolers have been in use for a very long time. It enables fuel efficiency.įor all of you who wondered what a modern heat exchanger looks like, look no further. This is a small cargo ship with two modern sail arrangements. Lots and lots of very interesting and very detailed ship models! I have taken several images of various kinds of ships. ![]() This particular engine is rated at 1000kW (1341HP) at 1000RPM. Not just in the merchant navy, but also in stationary shore applications. There were several engines, running on alternate fuel, such as Hydrogen! These sorts of engines have already been in use for some years. I had a good look at this one as it was very similar to the little Volvo F16 Truck Engine I built not too long ago ( (Building a (model) Volvo F16 engine))Īs you would imagine, there was a lot of emphasis on various environmental themes. You will see a lot more (Diesel) engines. One of the first things I bumped into was the Volvo Diesel. One of the companies involved must have some relation with the maritime industry TeamBHP being a car forum you will be happy to see, that the very first thing I came across was a car!! For the life of me, I can't remember what it was doing here. It just shows how I wandered around this massive event, spread out over 8 halls. The images I will be showing are not sorted in any particular order or topic. So on Tuesday I drove my Mini to the nearby station and took the train and bus to the Ahoy Congress Halls in Rotterdam. I mean if they let me in, anybody can get in. But it is not that difficult to get a free entrance ticket. This event is not open to the general public. ![]() Although a lot of it is maritime-related (Duh!) it also shows a very wide range of technology and its various applications. I visited Europort 2023 earlier this week and this thread is a collection of what I came across. We have several threads on the forum about the (merchant) navy and we have several members who worked or are still working in this industry. Ranging from building superyachts, tub boats, maintenance ships propellers, electronics and lots more. The Netherlands has a very long maritime tradition and there is a considerable maritime industry based in the Netherlands. To date, Rotterdam is still among the largest and most modern harbours in the world. ![]() Europort is essentially the harbour area of Rotterdam. Every year, for as long as I can remember, the Netherlands has held a huge international maritime congress, known as Europort. Most of my time at sea was spent on ocean-going tugs and Anchor anchor-handling vessels and a few other offshore support types of vessels.Īlthough my sailing days are long gone I have always remained interested in the marine industry. From general cargo to bulk carriers, and container vessels. I have worked on a large number of different ships. I spent the next 10 years as a Marine Engineer working for various shipping companies. Four years later, of which the 3rd year was spent aboard a Dutch General Cargo ship (full 365 days) I graduated. In 1976 I started at the Dutch Merchant Naval Academy in Amsterdam, the Netherlands, as a student. ![]()
