Ive been recently interested in offshore contruction ships like the ones in the pictures, but couldnt understand so far, why there are still conventional crane vessels like the DEME Orion, when much more stable plattforms like semi-submersibles like the Hereema Sleipnir or jack-up vessels like the DEME Innovation exist?

Jack-up vessels get stability from lifting themselves out of the water by standing on their piles that in turn stand directly on the sea floor, which obviuosly only works in shallower wtaers.

Semi-submersibles get stability from lowering their center of gravity by several meters by flooding ballast, which seems ideal for deep waters. In the case of the aforementioned Hereema Sleipnir that apparently makes a difference of up to 20 meters of draft.

How do conventional vessels pull this off, when the other typed have to put so much effort into stability, especially since the crane is deployed mostly to one side of the vessel?

I have no experience in maritime/naval architecure, just genuinely curiuos.

The vessel’s name means - “She who shows us the way” (Anishinaabemowin - in the Ojibwe language, the name was chosen by community elders).

I'm not really into ship THAT much, but I do have a few personal favourites, for no reason (or at least for a reason which I cannot verbally explain). And no, I'm not some "larper" who only likes warships. I like other types of ships as well, they are all very cool, I don't discriminate against no ship, 'cause why should I? (Imagines not in order. Mods, please do not ban my post for being "low effort" because I put hard effort into my selections):

-RMS Titanic

-USS Iowa

-SS Alpina

-Vasa

-SMS Konigsberg (1905)

What are YOUR favourite ships?

Just before twilight U-23 made her way past British escorts at Kirkwall and spotted the anchored Danmark, firing a single torpedo which caused the tanker to explode, break in two and sink immediately in the shallow water. All 40 crewmen survive, 12 with burns, and are rescued by harbor tugboats. The Danmark was inspected and declared a total loss.

Entering Thames Gateway this morning BARZAN is within limits at an LOA of 400M.

From the commercial side, the cheapest power you can add is often the power you stop wasting on a dirty hull. Air lubrication and clever appendages help, but after a long idle spell in warm water the slime and barnacles will eat those gains before you clear the anchorage. In our CleanShip work off Fujairah we see the same pattern: clear the underwater fouling first, then the design tricks actually show up on the noon report.

The world's oldest shipwreck has been discovered off the coast of Turkey, archaeologists say.

They have dated it to between 4,400 and 4,700 years old, which is the Early Bronze Age, and is around the same time that the Great Pyramid was being built.

The ship's wooden structure has not survived, but the ceramic storage pots it was carrying were lying on the sea floor and, remarkably, some still contain traces of what they held inside.

The archaeologists who found the ship say it was about 10m in length and was a trade vessel carrying cargo across the Mediterranean Sea.

"The shipwreck is a time capsule at the bottom of the sea," said Prof Hakan Öniz, from Akdeniz University in Turkey, who led the Mediterranean Archaeology Association expedition.

The wreck is close to the shore of Kekova Island in Antalya, Turkey. The artefacts lie scattered across an underwater slope, just 30m beneath the waves.

Three large stone anchors were found, as well as more than 30 ceramic storage pots, called amphorae.

The fact that none of the ship's wood remained meant techniques like radiocarbon dating - which measures a form of carbon in organic materials - could not be used to determine its age.

Instead, archaeologists analysed the shape of the amphorae. Because pottery styles have changed over time, differerent styles are linked to particular periods.

The Kekova ceramics are distinctive, with two handles, a ridge in the middle and a flat base.

Öniz said this design matched other amphorae unearthed in Egypt and the Middle East that were known to be 4,400-4,700 years old.

"Comparing the decoration techniques… we can definitely say our wreck is Early Bronze Age. This is 100%."

Island Challanger, Island Champion, Island Clipper, Island Empress,

Fairly certain the one closest is a Colorado-class, but I’m not knowledgeable enough to know which one. Looks like there is a stamp from 1936 if that helps date it.

Thank you in advance!!

Hey!

I ordered a BYD Sealion 7 and I'm tracking the car carrier that might bring it. I think these ships are really cool but I'm in Germany, so I can't see it myself.

Could someone near Zeebrugge take a photo of the BYD CHANGZHOU (IMO 9955076)? It's been sitting since 13 Oct in the southern part of the port, at the end of a long quay (roughly 3 km SE of Zeebrugge town, ~2 km east of Lissewege on MarineTraffic). It should leave around 15 Oct (my guess).

Thanks a lot!

I have been travelling for three weeks across the coast of West Africa and suddenly picked up interest in working on a ship. Seems like the best Adventurous job out there! I have been in IT/Blockchain for a few years and God knows i coveted working on ship right now. I am also a Drone pilot, i figured flying a drone might come in handy while working on a ship.
