[EDIT] FLIP is saved!

Well it had to happen eventually. #Scripps is retiring FLIP (FLoating Instrument Platform). This is an amazing piece of engineering (and soooo weird on the inside - everything pivots, so walls become floors). The #ship to be towed out to a location, and it would literally flip, sinking most of the ship directly down to give a *very stable platform for #oceanography research. Launched in 1962.

Flipping FLIP ship saved from scrapyard at last minute

The US Navy and Scripps Institution of Oceanography's unique FLoating Instrument Platform (FLIP) has been saved at the last minute from the breaker's yard. Scheduled to be scrapped in Mexico, it was purchased by undersea design company DEEP.

OK, everyone, I get it. Everyone loves weird research ships and #oceanography, but I give up and have temporarily muted notifications this thread. 😁😘

I'll make an effort to respond to questions though πŸ€—

Here are some excellent videos on FLIP to keep you busy.

ROTFL.
The bathroom of #Flip is cool.

@DrPlanktonguy "This was not called execution. It was called retirement." Vale.
@DrPlanktonguy Dont try this at home people

@DrPlanktonguy

I was today years old when I even learned something this awesome existed, only to hear it's being retired.

Wow.

@DrPlanktonguy this is pretty nuts.

I must know: for how long was the ship meant to stay flipped? And what was the main advantage? Having stable sensors deep underwater? What about storms? Where below sea level movie nights possible for the research team?

@IvanRManuel excellent questions. The FLIP ship could have missions about a month long. The whole idea around FLIP was to have 300 ft (91 m) of the hull submerged, and sensors could be all along that depth (plus winches on the surface could deploy sensors much deeper). It was all about stability because most of the mass was below water. They joked about it being "world's largest spar buoy". Not sure about movie night (it was rather spartan) .

@DrPlanktonguy @IvanRManuel Some sci Fi space ship interior sets could have been amazing if they took inspiration from Flip for thrust gravity vs landing modes.
@wrosecrans @DrPlanktonguy @IvanRManuel The Expanse is quite good at realism, but even there ships land with their engines pointing downwards when they go down to a planet IIRC. Changing directions is an interesting moment/sequence though. #FlipAndBurn #TheExpanse

@DrPlanktonguy @IvanRManuel

I continue to be confused by the receive to where flip's mass is as a reason for its stability. Is expect that you'd care about c-o-gravity to c-o-buoyancy distance for roll stability and about cross section at surface level for stability in room and in vertical motion (because, respectively, that controls the changes in buoyancy caused by waves and horizontal drag forces exerted by waves). Is there any reason location of mass directly (i.e. other than via the c-o-g vs -b distance) affects stability?

@DrPlanktonguy @IvanRManuel Jesus Christ, I thought that was a toilet for a moment..

@DrPlanktonguy

I'm surprised a billionaire didn't buy it to go with their mega yacht.

@jonhendry the toilets aren't gold plated so that is a serious downside.

@DrPlanktonguy @jonhendry

On this ship, the down side keeps changing.

@DrPlanktonguy this is very unsettling
@DrPlanktonguy Why oh why have I never heard of this? This should have been a TV science programme.
@NormanDunbar even for my students, it was generally their first experience with this ship. FLIP was however very popular for a "virtual schoolroom". Scripps provided a number of videos as well for educators.

@DrPlanktonguy I wonder how often they had to tell helpful captains that they were "fine, but thanks for checking."
@DrPlanktonguy @luciedigitalni I’ve known this thing my whole life, what a marvellous thing, I hope ifs function is replaced
@corduroy @luciedigitalni many of the measurements can be done now using autonomous ocean gliders, but no question, it was an amazingly useful feat of engineering for its time.

"restricted maneuverability"
@sabik @luciedigitalni definitely not its strength - especially having no engines 🀷

@DrPlanktonguy IVE BEEN THERE IVE BEEN THERE

IN A GAME!!!

SOMA, awesome game, by @frictionalgames

@DrPlanktonguy Why isnt there a Tom Scott Video about that?
@DrPlanktonguy Wonderful! The marine version of the V22 Osprey!
@DrPlanktonguy only just learned this existed, and i will miss it terribly.

@DrPlanktonguy @hbons little known fact, this is how you plant a ship. In time it will grow and become a cruise liner.

Nature is beautiful.

@DrPlanktonguy it must've inspired lots of urgent calls to the coastguard during deployment.
@DrPlanktonguy interesting to think about. Vertically it look very stabile. How did the engineers ensure that the ship while pivotting wouldn’t tilt sideways?
@hylk3 the ballast tanks were designed to fill with water and bring that part of the ship gradually downward over a 30 minute period.
@DrPlanktonguy i've always felt like this must have been something someone proposed as a joke and then had to commit to it when it got approved
@DrPlanktonguy I remember reading out that in National Geographic when I was a kid. Amazing it lasted so long.

@DrPlanktonguy

I was in elementary school in the late 60s and I'm pretty sure I saw something about this ship at that time.

@DrPlanktonguy how is this the first time I hear that this thing exists in my 40+ years of existence
@DrPlanktonguy IIRC- Yup, the lack of a propulsion system really limited the possibilities for the Navy to continue to sponsor it under Office of Naval Research funding. Is a replacement planned, or will efforts focus on RVs & oil platforms?
@camstonefaux my understanding is that the combination of autonomous Ocean #Gliders, profiling #ARGO floats, and new advanced ships that can deploy #ROV and other instruments is the focus. Scripps also has a brand new hydrogen powered hybrid #oceanography vessel being built to replace the RV Robert Gordon Sproul.

@DrPlanktonguy I know you posted a source and everything but I still refuse to believe this is real πŸ’€
@hazelnot trust me, it is even stranger in-person.
@DrPlanktonguy @SRLevine Whaaat? 😳 That is WILD (and very clever)!
@DrPlanktonguy This makes me kind of sad, I've known about this vessel for a long time, and always thought it was amazingly cool engineering
@ghostcubby Walter Munk did much of his groundbreaking research on physical #oceanography based on measurements from this ship. Being able to measure changes to the surface ocean with the development of #storm systems was essentially impossible before FLIP was built.
@DrPlanktonguy I've sailed by that ship several times and always thought it would be amazing to be in when it flipped.
