Thank you for the shout mate! I didn’t expect that at all. I will be releasing a Bayesian video this Friday and will dive deeper into the dive footage. Some interesting things in that footage. Cheers🤙🏼
Question: What kind of gas do you use for a working dive at 150 ft and what kind of bottom time can you get and how much decomposition do you need? I have over 350 dives in the Red Sea. Even made it to 165 ft for an amphora.
eSysman, your coverage is professional and honest. Investigations are slow and tedious. People are accustomed to TV, where everything is solved in 1 hr.
I nearly commented about ear muffs, but decided it was worth the effort! Phew, saved me from being called out 🤣🤣 Love how you cover the story in a way the media doesn't. Low key, no drama and keeping the rhetoric on an even keel.
Please don't take any of the comments personally. You have to remember that you a have a very diverse audience, with lots of different opinions. We are only here because you are getting it right. Please keep the good work. You are on the right track. 👍
As the son of a father who served on the Huges Glomar Explorer, I’ve always been fascinated with salvage and raising operations particularly given how each scenario offers a unique set of challenges. Love this channel, keep up the incredible work 🍻
used to see the Glomar mothballed in Suisun Bay we would take our boat and get close before it was sent up to Portland for a refit in the 90s to a drilling rig sadly it was scrapped after 18 years as a drilling rig...was a nice vessel
If you're interested in salvage there's a bunch of old videos on TH-cam that various salvage companies made back in the 70's & 80's... not just well known jobs but lots of different vessels like crane barges & ROROs. An interesting one where they were clearing multiple wrecks out of a channel in Europe at the same time, and half the team were dealing with a historic wreck while the others put slings under a more modern boat & just lifted it out in one piece. Worth watching if you're interested... and complete with 70's/80's "health & safety" standards to wince at! 👍

As a yacht owner of 35 years. I have had my achors drag. 1. Ensure the boat is taken control of.....start engines and ensure the boat is ready for open water keel down in my case. It took four minutes. 2. Make boat safe. All instruments active. Spin up took five minutes. 3. Ensure boat secure. Took me two minutes. In their case, close water tight doors. Including life jackets accessible. And emergency gear readied. 4. raise anchors. A must. Took a while for me. The baysian is a massive complex yacht, and to get it ready for open water in an instant would have taken a lot longer. Perhaps more than 16 minutes.
Thanks for this. you've obviously worked very hard on this to help us understand and also to explain with some of your own in depth knowledge of the modern yacht.
The divers would definitely have cut through the rotating threaded bar which winds the door open or shut. The long bolt is easily visible in the excellent door demonstration video that you found. The 'Jaws of Life' would have sheared through that long bolt easily once access to it was gained through a wall panel that concealed it. Only the weight of the actual door would need to be overcome by the bottle jack once the bolt was cut.
I agree ! you cant force does "electro hydraulic " actuators if the motor is not spinning. The only way is to overload the treads in the ram nut until failure, or cut the threaded rod . If you consider that these doors are designed to overcome "diffrent types of debre" in the doorway in a emergency by cutting it of ,these actuators is probably substantial in force.
Great video answering some of the questions. The blue ear muff sign is there to say hearing protection must be worn inside the engine room. All the navy ships and boats I've served on had manually dogged watertight doors and hatches. You want to be able to use them on a weapon of war regardless of the state of the ship.
This whole thing is really interesting with the differences in how people have approached discussions between this vessel and the NZ Navy vessel which I think you have pointed out. I feel like commentators have missed tge obvious 'you cant help anyone until you help yourself'. That crew most likely didnt have the option to rescue anyone else in those conditions.
I'm amazed that you even humored some of those comments, especially the ones about gravity closing dogged and/or screw-driven doors and the ones asking why it hasn't been raised. Go find the videos of the Costa Concordia raising process, my fellow commenters. It was a bit "involved" (doubly so because the bottom was steeply sloped where it came to rest and IIRC they had to be very careful not to push it out into deeper water in the process).
At this point I would like to pay you a very big compliment for how precisely and carefully you always describe things. It's all the more astonishing to see what little/unimportant things bother people again and again. I think you're doing an excellent job, keep it up so big, big praise 🍀🍀🍀👍🥇
It might have been written already, but these are not commercial divers, they are Navy personnel, since you can clearly see Marina Militare written on their wet suit. This was also confirmed by Quarta Repubblica, who stated that they are members of the CONSUBIN, which is the Navy special operation unit. CONSUBIN has two sections, Incursori (raiders) and Subaquei (divers). These are clearly the latter, whose specialty is to rescue stricken submarines but who also intervened on the Costa Concordia early on. As you recall, the initial rescue dives were carried out by the Vigili del Fuoco (firefighter units). CONSUBIN was called in later, allegedly to recover sensitive item and secure the perimeter.
Raising a sunken vessel from the seabed is often done using pumped up flotation devices in combination with the tidal movement and incrementally bring the vessel in from deeper water to shallower depths. It sounds complicated and it can be hard to get right but it does work.
Knowing the difference between headphones and ear defenders - at all times and under any circumstances- is an absolutely crucial life skill. Crucial! That's why we all take several mandatory college courses - ear defenders vs headphones 101.

To add to your unnecessary corrections. The door open/close electric motor is not a rack and pinion but a worm drive. Worm drives are like a nut and bolt, the thread turns and the nut travels along it in the direction of the turning thread. ;-)
Yes and there is an emergency hand crank 2 foot below the switch, at 12:40 in case the power is out. So anyone could have operated the door at any time even underwater.
@@will7its That really is a good suggestion for a James Bond film. On a submerged ship, our hero finds the emergency crank and opens the door to get out. I suppose this would be too much, tough, for normal passengers, even if they had listened to the safety precaution routine.
@@uffa00001 My point was that it could have been opened or shut by the divers so being closed now is not proof of anything. Still a lot that's very fishy about this boat.
I am now 22 years working on MY's as Ch.Eng. WAY too long!! I have a personal theory of how it sank & that is now enforced by evidence of the shattered window in the ECR. This is a massive clue.The E/R door would have been closed period. It now looks like the Watertight door between the lazz & ECR, was also closed. Down flooding of the E/R as she sank though the water column, plus the Lazz also flooding as she went down, caused the water pressure in E/R to shatter the glass, as the ECR was still a sealed compartment full of air. If the watertight door was open leading into the ECR, I truly believe the glass would be intact. As there would not be a pressure differential. Giovanni Costantino, has a huge defamation law suit heading his way.🎉🎉
At 50m the pressure would be 70 psi or about 5 bar which would result in a pressure differential of 57 psi, 4 bar. Another factor is how quickly did the yacht sink as the rate of change in pressure could be a factor. Also could the window have been shattered by someone trying to escape or have been hit with debris?
Come guys!! Haven't you see the movie Airport 1977. They raised a 747 with balloons. Zip down there, connect them and zip out. Its like going to Wisconsin.
Thanks eSysman, I thoroughly enjoy listening to your reasoning.. Loads of unbiased information supported by researched facts. You're a gem of a journo!!
The electric mechanism to open and close the door looks to me like a 90º gear box which will have a worm gear from the motor to the Ball screw. There is no way to force this so opening the cupboard and disconnecting the mechanism at some point would have been necessary to get the door open.
Well...... you might just be correct about the hearing protection being able to transmit audio after all. Many systems have noise cancellation, built in mics to allow communication between crew members. People who hang onto every word to criticize are very annoying. Thanks for your hard work keeping us updated on the water.
Sent a shiver up my spine when watching the underwater footage - so freaky seeing what was once on the water now underneath it! Take my hat off to divers. I did it for a while, but now just freak out just at the thought of it. Thanks for the update
One thing that has come from this unfortunate accident.. Engineers can learn and make changes to Yachts to make them safer. If it does go down in a situation like this, there should be safety measures for help to get inside of the Yacht easily for a Rescue.
Having raised a 150 ton tug, the way that we drained the fuel was getting into the fuel intake line and pinching off the large rubber hose to the fuel tank with a hose clamp and running 350ft of 1 inch rubber hose down to the wreck in 180ft of water. Fuel floats and it traveled up the hose to the barge overhead where we were able to pump into a holding tank. Unfortunate oil in the engine is a different story and there isnt much that can be done. We would come out of the engine spaces covered in it. On boats and yachts, id assume that you could go directly to the fuel filling opening and jam a hose and begin to suction pump out of there and remove the majority of the fuel that way.
Thank you for the well researched and informed update. I particularly like the explanations of how the watertight doors work. This sort of thing provides a good insight into how the yacht was operated. Intereresting that the captain/bridge can set the doors to close yet the door can temporarily be opened by holding the button, and then it returns to the closed position. I hope there is data available on the movements of all of the doors. It will be interesting the see if the investigation produces a matrix of such elements of the operation of the vessel to set out clearly the history and status of various systems, I find it much easier to review a matrix for such things, than a long wordy document, although a narrative is good to explain and conclude.
Thank you for all the time you spend preparing these videos, your careful analysis of the material you got from Italian tv is very valuable. In a way, the "Quarta Repubblica" insights with videos and stuff are quite unexpected as well, since the programme is almost exclusively focused on sensationalistic topics. During the last broadcast, they also switched to a more comprehensive version of the sinking, much less oriented to point to the crew as the only culprit. This just to say that it can be interesting also to see how many videos QR is going to release and what information can leak from them
To pump the oil out, They will use a bolt gun (same as the RN uses). The bolt has a removable point, so you end up with a hollow pipe through the wall of the tank with a hose connection. Although the tank connections on a yacht like this are very easy to manipulate, so they may just line them up to a fitting on the diesel polishing unit and pump them out from there.
When the Mary rose was lifted they needed a frame the monitor was lifted a frame 99.9% of the time you need a lifting frame My experience was recovery of aircraft from below the surface it not easy things that you need to check Fuel needs draining How to.preserve the vessel/ items integrity once on the recovery barge so investigators can if required look over the vessel/item The weight prior to sinking The weight now when full of water Weather conditions For the divers For the cranes ( as some times you may need 2 or more) The barge your going to put the item onto once on the surface Spill prevention from it draining once on the surface & on the lift & barge So it not like recover of bridge debris or seaman container or sunken cars
I was wondering why the watertight door needed prying open. It makes sense though, to get airbags into that compartment for the eventual refloat. Great work by those divers!

Flippers 😂😂😂, you're going to get crushed for that!!!! I still call them that because that's what they are, but also because I still can't believe the reactions of my friends, colleagues and strangers who are (qualified 🤔 (( by paying PADI to get a bit of paper....))) divers and they really get unbelievably offended when you refer to their FINS as flippers. P.S. I'd be interested to know how it may compare to headphones, or should I say EAR DEFENDER'S!!
The hinged bridge door probably won't close or open by gravity or wind on itself, as the hinges usually have a high resistance for exactly the reason to prevent the door banging around in waves, wind or so. Making noise and endangering people. Also the video seems to show the port side bridge door and it doesn't close. Bridge doors are mounted opening aft in order not to swing by the wind, which most likely blows from the bow in an Anchorage. That proves the door shown is the port door. Which then shows, the door is hanging as the ship is on it's starboard side and the door doesn't even close by gravity or water currents.
You know that show is scripted right? It’s not actually news or even just a documentary about what happens. They actually write the events before hand and then act it out.
I’ve been following your reporting on this from an engineering failure interest point of view. Very interested to see if and how they raise it - asked the same on one of your early videos. Thanks for the ongoing info 👍
You would need the keys to open locked cabinets so popping open these cabinets with crowbar is probably the easiest way also the hard drives and memory chips can be restored but not after setting in saltwater for any long time
It's like the old days in newspapers! Name of the game used to be keeping the story rolling, chasing and checking new info every day, seeking expert opinions and reporting promptly. It keeps the readers/viewers coming back but is resource-intensive so MSM now prefers to fill their output with scatterbrained fluffy content that often comes from PR firms.
Every day is my Friday, and I don't dive either so this is all I have in my dreams. Have to mention that the Costa Concordia reefed and did not completely sink.
✨...interesting to hear from a diver, .... and details about the door systems, ....I’m a rookie big boat sailor, question: in what placement (open/close) , under these circumstances the proper door position.....should one close doors to prevent more flow in and passengers get out bc they can’t go against this kind of force via quick capsize .....maybe a silly question 🤦🏼♀️ 🙏🏼
My first entry level open water scuba class included showng ability to raise objects from the bottom. Basically attach the equivalent of a hit air balloon to object and insert enough air in it to cause it to lift it up. Obviously more complex for a bot since you need to know where to attach the ropes. But it will lift the boat to near surface where a crane could then ift it up some more and if the hull is not damaged, they can pupmp water out (hence imporance to keep watertifght doors closed). Having ship near surface maked ny/all recovery of artifacst insice infinitely easier due to diving being much easier.
Coming up from a depth of 50 meters, air in the ballons is going to expand 5x. That makes controlling rate of ascent a bit tricky. Also, even the slightest difference in the inflation of your balloons at 50m is going to make a huge difference to the stability of your load as the pressure decreases and the air in the balloons expands.
@@eleanorjames1118 The balloons (more like bags) are open ended so as air expands during ascent, the excess leaves so the balloon maintains its volume and bouyancy.
About the defueling the tanks on the ship, I have seen video of how the navy off loads fuel & oil from sunken ships. Special team and equipment puncture and seal hole of the tank take a sample. Then puncture and seal hose to the tank with equipment that sucks out and pumps it out to surface tanks.
great explanations as always, regarding the fuel, they can drain it from the sunken vassal, not sure of the correct name of the coupler but its similar to the one used to connect to gas mains where the pressure cant be reduced, the connection is done under full pressure, the coupler is in 2 and joins around the pipe with a riser, in the riser there is a drill bit attachment further up from the valve and it is sealed to the coupler, once the drill has penetrated the pipe it is withdrawn up past the valve and the valve is then turned off sealing the join, drill bit attachment is then removed and the pipe can be screwed into its place and the valve is then opened allowing extraction, the connecting pipe also has a valve ensuring it doesn't fill with water and once attached it can be opened , this method can also be used on the tank itself if the hoses are not at the low point of the tank, the coupler is this scenario has a flat base and is glued with epoxy to the tank its self, both methods require a breather line fitted in the same way to ensure no leaks, cheers TK Australia
Can the channel help me make a correction in the yachting world. My great great grandfather was one of the first people to put a steam powered winch on a boat to raise an anchor. The proper name for the winch is a windless as in wind your watch not as in the wind blows from the west. There are two types of winch's one that winds a rope around a drum, and the second, one that dumps chain into a hold.
This matter is becoming out of control. Lets not forget lives were lost, who cares about computer hard drives, we need that yatch raised with air bags intact ASAP without diver intervention to vessel to learn what precautions are needed to avoid this ever happening again without the chance of more repeat loss of life. As a skipper and qualified engineer this is mandatory to help us learn from the board of maritime enquiry recomendations. And only then will we know the truth so long as divers stop interfering with the wrecked vessel prior to raising and allow investigators to do their job.
Thanks for the great research and effort your team contributes. I'd really like to see some accurate reports on the wind direction or AIS track as Bayesian apparently dragged anchor towards the shore? I'd like to see where the anchor is now in relation to where Bayesian is. There's little info to this part of the investigation. If your team come across any accurate information regarding the anchor position and chain i'd love to know about it. Thanks in advance. Cheers
Not involved in marine salvage but I would think the simplest way to raise it would be to bring 2 barges with cranes into place. Anchor the barges to the sea floor. Drop 20x1m wide slings into the water tied to the barges with ropes and use ropes to pull the slings under the boat on the sea floor side. Space them as evenly as possible along the length of the yacht. Position a series of air cushions inside the yacht as evenly as possible. Any area with an external entry/exit that is not watertight make it water tight by closing the window/door etc. If you cannot seal it then seal the bulkhead door to the area. Start filling the air balloons with air to provide buoyancy from within Then very slowly start lifting the yacht with the crane. As it reaches the surface have industrial water pumps on hand and drop the hoses into the yacht and start pumping. Probably 2-4 weeks to set up and two to three days to lift/refloat weather dependent.
Mammoet salvage has a good video on “hot tapping” A procedure used for removing fuel from submerged wrecks. It may be more applicable to large ships though.
Thank you for the shout mate! I didn’t expect that at all. I will be releasing a Bayesian video this Friday and will dive deeper into the dive footage. Some interesting things in that footage. Cheers🤙🏼
Question: What kind of gas do you use for a working dive at 150 ft and what kind of bottom time can you get and how much decomposition do you need?

Thanks for your hard work keeping us updated on the water.
Sent a shiver up my spine when watching the underwater footage - so freaky seeing what was once on the water now underneath it! Take my hat off to divers. I did it for a while, but now just freak out just at the thought of it. Thanks for the update
Great follow up video with some excellent investigative work. Thanks 👍👍
One thing that has come from this unfortunate accident.. Engineers can learn and make changes to Yachts to make them safer. If it does go down in a situation like this, there should be safety measures for help to get inside of the Yacht easily for a Rescue.
Having raised a 150 ton tug, the way that we drained the fuel was getting into the fuel intake line and pinching off the large rubber hose to the fuel tank with a hose clamp and running 350ft of 1 inch rubber hose down to the wreck in 180ft of water. Fuel floats and it traveled up the hose to the barge overhead where we were able to pump into a holding tank. Unfortunate oil in the engine is a different story and there isnt much that can be done. We would come out of the engine spaces covered in it. On boats and yachts, id assume that you could go directly to the fuel filling opening and jam a hose and begin to suction pump out of there and remove the majority of the fuel that way.
You should call the segment Backseat Pilot Pedantry
?
Thank you for the well researched and informed update. I particularly like the explanations of how the watertight doors work. This sort of thing provides a good insight into how the yacht was operated. Intereresting that the captain/bridge can set the doors to close yet the door can temporarily be opened by holding the button, and then it returns to the closed position. I hope there is data available on the movements of all of the doors. It will be interesting the see if the investigation produces a matrix of such elements of the operation of the vessel to set out clearly the history and status of various systems, I find it much easier to review a matrix for such things, than a long wordy document, although a narrative is good to explain and conclude.
I like this format.
Great job on the VIDEO 😊
Thank you for all the time you spend preparing these videos, your careful analysis of the material you got from Italian tv is very valuable. In a way, the "Quarta Repubblica" insights with videos and stuff are quite unexpected as well, since the programme is almost exclusively focused on sensationalistic topics. During the last broadcast, they also switched to a more comprehensive version of the sinking, much less oriented to point to the crew as the only culprit. This just to say that it can be interesting also to see how many videos QR is going to release and what information can leak from them
To pump the oil out, They will use a bolt gun (same as the RN uses). The bolt has a removable point, so you end up with a hollow pipe through the wall of the tank with a hose connection. Although the tank connections on a yacht like this are very easy to manipulate, so they may just line them up to a fitting on the diesel polishing unit and pump them out from there.
When the Mary rose was lifted they needed a frame the monitor was lifted a frame 99.9% of the time you need a lifting frame
My experience was recovery of aircraft from below the surface it not easy things that you need to check
Fuel needs draining
How to.preserve the vessel/ items integrity once on the recovery barge so investigators can if required look over the vessel/item
The weight prior to sinking
The weight now when full of water
Weather conditions
For the divers
For the cranes ( as some times you may need 2 or more)
The barge your going to put the item onto once on the surface
Spill prevention from it draining once on the surface & on the lift & barge
So it not like recover of bridge debris or seaman container or sunken cars
I was wondering why the watertight door needed prying open. It makes sense though, to get airbags into that compartment for the eventual refloat.
Great work by those divers!
Obviously the electric open did not work.
Headphones, earprotectors..... We used to call them a Mickey Mouse.
Love all your videos .
Older Holmatro tools are waterproof to 40 meters and can be used by divers, new ones are "splashwaterproof"
Great Job!!!
Another great, detailed report! Thanks, PMc
SMIT Salvage (Part of Boskalis) is synonymous with total commitment in the challenging field of sustainable marine emergency response and wreck removal. Whether it concerns a distressed Bulk carrier, Container vessel, Tanker, Offshore structure or otherwise, SMIT has the experience and in-house knowledge to deal with any type of vessel anywhere.
LOL the corrections need to be corrected and so on = what a deal....Thank you eSysman for the update video.....
Old nasty flying Shoe🇺🇸
You are doing a damn good job😊😊
Esysman - you doing great work on this. Thank you
Bayesian will definitely be raised. It's an extremely high profile case with multiple ultra rich deaths.
And probably an insurance company(s) looking for any reason(s) to avoid paying off claims.
I believe that the owner of the vessel (effectively Mrs Lynch) is under a legal obligation to have it raised.
great work mate. As a shipwright I'm following this with great interest.keep up the great work
Flippers 😂😂😂, you're going to get crushed for that!!!! I still call them that because that's what they are, but also because I still can't believe the reactions of my friends, colleagues and strangers who are (qualified 🤔 (( by paying PADI to get a bit of paper....))) divers and they really get unbelievably offended when you refer to their FINS as flippers.
P.S. I'd be interested to know how it may compare to headphones, or should I say EAR DEFENDER'S!!
Don’t underestimate the skills of the diverse. They are going into a confined space at 50m and this is not a simple task.
Thanks
The hinged bridge door probably won't close or open by gravity or wind on itself, as the hinges usually have a high resistance for exactly the reason to prevent the door banging around in waves, wind or so. Making noise and endangering people. Also the video seems to show the port side bridge door and it doesn't close. Bridge doors are mounted opening aft in order not to swing by the wind, which most likely blows from the bow in an Anchorage. That proves the door shown is the port door. Which then shows, the door is hanging as the ship is on it's starboard side and the door doesn't even close by gravity or water currents.
Regular viewers of Top Gear/The Grand Tour know, that "How hard can it be?" is usually the announcement of an imminent catastrophe.
"In this episode, Richard pilots a yacht into a waterspout".
You know that show is scripted right? It’s not actually news or even just a documentary about what happens. They actually write the events before hand and then act it out.
Love these videos,
and that you like Porsche 911's and Riva launch?. 🥰
Looking forward to the future antipedanticalization video; should be fun. 😄😇
I’ve been following your reporting on this from an engineering failure interest point of view. Very interested to see if and how they raise it - asked the same on one of your early videos. Thanks for the ongoing info 👍
You would need the keys to open locked cabinets so popping open these cabinets with crowbar is probably the easiest way also the hard drives and memory chips can be restored but not after setting in saltwater for any long time
Could the doors have closed after being submerged and shorting the switch. A bit like car windows and doors lock when submerged in water
Thank you, keep working.
Impressed that u came up with this video plus research only 24 hours later
It's like the old days in newspapers! Name of the game used to be keeping the story rolling, chasing and checking new info every day, seeking expert opinions and reporting promptly. It keeps the readers/viewers coming back but is resource-intensive so MSM now prefers to fill their output with scatterbrained fluffy content that often comes from PR firms.
Every day is my Friday, and I don't dive either so this is all I have in my dreams. Have to mention that the Costa Concordia reefed and did not completely sink.
Thank you. Nice info
✨...interesting to hear from a diver, .... and details about the door systems, ....I’m a rookie big boat sailor, question: in what placement (open/close) , under these circumstances the proper door position.....should one close doors to prevent more flow in and passengers get out bc they can’t go against this kind of force via quick capsize .....maybe a silly question 🤦🏼♀️ 🙏🏼
My first entry level open water scuba class included showng ability to raise objects from the bottom. Basically attach the equivalent of a hit air balloon to object and insert enough air in it to cause it to lift it up. Obviously more complex for a bot since you need to know where to attach the ropes. But it will lift the boat to near surface where a crane could then ift it up some more and if the hull is not damaged, they can pupmp water out (hence imporance to keep watertifght doors closed). Having ship near surface maked ny/all recovery of artifacst insice infinitely easier due to diving being much easier.
Coming up from a depth of 50 meters, air in the ballons is going to expand 5x. That makes controlling rate of ascent a bit tricky. Also, even the slightest difference in the inflation of your balloons at 50m is going to make a huge difference to the stability of your load as the pressure decreases and the air in the balloons expands.
@@eleanorjames1118 The balloons (more like bags) are open ended so as air expands during ascent, the excess leaves so the balloon maintains its volume and bouyancy.
About the defueling the tanks on the ship, I have seen video of how the navy off loads fuel & oil from sunken ships. Special team and equipment puncture and seal hole of the tank take a sample. Then puncture and seal hose to the tank with equipment that sucks out and pumps it out to surface tanks.
Thank you, really enjoy your channel.
Great job, full of interesting details. Thank you
Hey sysman we use ear defenders with a communication setup in the tree cutting industry and call them headphones, good video mate enjoyed it
great explanations as always, regarding the fuel, they can drain it from the sunken vassal, not sure of the correct name of the coupler but its similar to the one used to connect to gas mains where the pressure cant be reduced, the connection is done under full pressure, the coupler is in 2 and joins around the pipe with a riser, in the riser there is a drill bit attachment further up from the valve and it is sealed to the coupler, once the drill has penetrated the pipe it is withdrawn up past the valve and the valve is then turned off sealing the join, drill bit attachment is then removed and the pipe can be screwed into its place and the valve is then opened allowing extraction, the connecting pipe also has a valve ensuring it doesn't fill with water and once attached it can be opened , this method can also be used on the tank itself if the hoses are not at the low point of the tank, the coupler is this scenario has a flat base and is glued with epoxy to the tank its self, both methods require a breather line fitted in the same way to ensure no leaks, cheers TK Australia
“Unnecessary Corrections” might make a good band name! 🎶🎵
Can the channel help me make a correction in the yachting world. My great great grandfather was one of the first people to put a steam powered winch on a boat to raise an anchor. The proper name for the winch is a windless as in wind your watch not as in the wind blows from the west. There are two types of winch's one that winds a rope around a drum, and the second, one that dumps chain into a hold.
Drachineiffel's channel might do a video on that
They've sure come a long way. Now their hydraulic or electric, and if electric, available in various AC & DC voltages.
I think it's "windlass"...not "windless".
So, there, you've been corrected 😉
This matter is becoming out of control. Lets not forget lives were lost, who cares about computer hard drives, we need that yatch raised with air bags intact ASAP without diver intervention to vessel to learn what precautions are needed to avoid this ever happening again without the chance of more repeat loss of life. As a skipper and qualified engineer this is mandatory to help us learn from the board of maritime enquiry recomendations. And only then will we know the truth so long as divers stop interfering with the wrecked vessel prior to raising and allow investigators to do their job.
Watch the video. The divers are working to make it possible for the investigators to do their job.
Fantastic Investigation !
Great video and I hope the authorities in Italy are as thorough as you analysing the footage they get back. Keep up the great work 😀👍
Unlikely
Never call them "Flippers"
Thanks for the great research and effort your team contributes. I'd really like to see some accurate reports on the wind direction or AIS track as Bayesian apparently dragged anchor towards the shore? I'd like to see where the anchor is now in relation to where Bayesian is. There's little info to this part of the investigation.
If your team come across any accurate information regarding the anchor position and chain i'd love to know about it. Thanks in advance. Cheers
Not involved in marine salvage but I would think the simplest way to raise it would be to bring 2 barges with cranes into place. Anchor the barges to the sea floor. Drop 20x1m wide slings into the water tied to the barges with ropes and use ropes to pull the slings under the boat on the sea floor side.
Space them as evenly as possible along the length of the yacht.
Position a series of air cushions inside the yacht as evenly as possible.
Any area with an external entry/exit that is not watertight make it water tight by closing the window/door etc. If you cannot seal it then seal the bulkhead door to the area.
Start filling the air balloons with air to provide buoyancy from within
Then very slowly start lifting the yacht with the crane.
As it reaches the surface have industrial water pumps on hand and drop the hoses into the yacht and start pumping.
Probably 2-4 weeks to set up and two to three days to lift/refloat weather dependent.
Mammoet salvage has a good video on “hot tapping” A procedure used for removing fuel from submerged wrecks. It may be more applicable to large ships though.
