Recover a sunken boat

[Ruky]

I got for first time this mission, recover a sunken boat which is at 300m depth... I though that it was a joke when I saw it but it is real.

To be honest that was the kind of task that I wanted to see since started playing some years ago, not sure if it is something that devs added recently or it has been here for yes and I have been unluky, but I have never seen before and never read about it at the forums.

Yes the ship is there, I still have to think how to do it because I am on career and I started this game play few days ago so my founds are really limited.

I've never had it before. I think it was part of this week's minor update. On how to recover it.. try using heavy lift helicopters. Vtols will work. Drop a winch, dive down and attach it, then lift to destination. I can't think of any other way.

I am thinking to build somethig like the kommuna... but the winch should be a kind of ROV with several magnets

Sure. Sounds like a fun project

Could I help?

Its been a mission since the under water biome update, but this is the first time I have seen a boat that deep

I don't know how... but I can send you the save game if you wanna try it.

If you wouldn't mind, yes pls.

Something else you can do to help lift flooded vessels is attach floats to them.

Perhaps you could design large and long tanks that you intend to attach to each side of the ship. At the surface you fill these with water to neutral buoyancy and tow them down to the ship with a submarine.

To refloat the ship you would need to blast compressed air into the tanks. (At that depth you would need to use a rigid pipe rather than the hose, I expect.)

The Kommuna idea will work though, there's a vehicle like that on the workshop somewhere that can lift something that size easily. (You may have to upgrade the winches as 300m is only reachable by the huge winch, I believe.)

I am building Otis, It has a big ROV/anchor to try to pull the ship from the bottom

But if it doesnt work maybe I will try the idea of attach ballast tanks to it.

For practical purposes with a regular monohull or full deck catamaran I'd suggest using an A-Frame crane at the stern with a huge winch on the crane, should get anything off the seafloor.
With a decent fulcrum you can leverage the ships mass, having one on my cargo catamaran as can be seen in this image:

The frame can lean forward / backward up to ~60° with hinges, powered by piston stacks.

Works a treat. You might be able to use multiple huge winches utilizing pulleys for better control / lifting power.

Definitely something to play around with. The few vehicles I've lifted with it were rather uneventful to get on deck.

Used it frequently back when the helicopters crashed into the sea upon spawn due to buggy AI.

You could also have a huge winch connected to a pump and connect it with hoses to a portable fluid port you put inside the sunken ship
