A split hopper dredger will actually split open its hull to dump the soil

Just putting back what the wind, tide and weather will move.

They actually calculate sediment dispersal when dumping soil. They know where the majority of the soil will end up in time

I know they risk-assess every detail. Nature just 'does its thing'.

I do a lot of that

That is not soil, it's sediments.

I bet you're the light of every party

@lamadrid56 I grew up in a place, where almost all soil is good for growing crops, vegetables etc, and to regenerate/create it again is almost impossible, so my first thought was "wtf are they doing with the soil, this is literally a crime". Sediments is another story, so yeah

@BartGonnissen Take it as a learning experience. Soils have a very specific definition. I was in the middle of my PhD when I understood the difference between soils and sediments. So I was not trying to dis you. (Nerd parties love me... it is an Uhmmm actually fest!)

Engineering simplicity often drives massive efficiency.

Leuk om te zien! In een grijs verleden (1988) als sparks op de Rocky Giant van Roterdam naar Hong Kong gevaren. Deze stenenstorter ging daar aan de bouw van het nieuwe vliegveld werken.

Fish be like

Thnaks I learned something new today

In the early 60s I worked for a small marine design company (T T Lunde inc) in San Francisco. We then had a good patent for dump barges & built several. Then this came out. We built no more after that, but other good stuff fortunately.

So this is how you build an island

Thats insane....

split hopper dredger haters when the hopper dredger actually splits

Flashback naar een spreekbeurt in het middelbaar.. lol

Whay are they dumping the soil?

Sometimes, it's used for construction, but sometimes you need to maintain certain spots that are eroding too fast

Ok. Tx

haha, thought it was broken

😲😲

@grok AI or Real

How does the ship stay afloat in the process?

It just has natural buoyancy. You could almost compare it to a catamaran

Okay got it, thanks

This is for all the soil to fall out .. the hull closes after it’s empy.

Had to dry dock one a few years ago. Nerve wracking when you’re in the water and checking to make sure it lands on the blocks when they start dewatering the Drydock.

Boat has real "Hold my beer" energy around being watertight etc - love it!

@grok, what's the size of the biggest one?

Is that what NYC used to use to dump sludge off the Jersey beaches?

@grok whats the purpose for this?

@grok why they doing that?

Where is Spider-Man?

This is what China uses to dump trash

White people did it

The way the entire hull just splits open is insane 😳 Engineering on another level.

The engineering needs complement... Remarkable 🤩

WTF?? how does that not sink???

The fish below be like

Amazing

They are dumping bad substances all in the name of dumping soil
