WOO WOO WOO !!!
anyone with a yacht should be paying for us normal Canadians carbon tax. the rich pollute 1000x more than us normal people
I wouldn't call myself an expert, but I worked in dry docks and the best, cheapest, safest solution is to rope the boat and flood the drydock. The damage has already been done. Re-float it and pull it out. Reset the blocks and try it again. They'll probably modify the dock plan beforehand.
I hope the shipyard has damn good insurance as its going to get seriously clobbered!
@Brian Waas they dont fill quick enough to do that
for those arriving late she is now AFLOAT, with a heavy starboard list but is floating and has been moved out the dry dock
Didn't imagine with the equipment shown installed... Was going to be too awfully long before she was upright(ish)
Flooding the drydock is the best way to right a ship of that size. The hydraulic jacks against the keel are to hold the keel in place so that it stays centered on the blocks as it starts to right itself to try and keep damage at a minimum, and the straps hooked to the side of the hull will pull tension to help right the ship as it starts to float.
The simple sees too obvious.
Yes, I think when the ship toppled her keel slid to port on the chocks. The hydraulic rams are currently retracted. When flooding the dock, at a point when she starts to float, the hydraulic rams will push the keel to starboard back into the original position on the chocks. The strops will prevent the upper part from following the movement of the keel.
Without such restraints in place, at a certain point of flooding, she would "bob up" and lurch to port and strike the dock wall. The crane was probably used to lower the hydraulic rams and provide a suspended work-platform for the welders to fit the attachment points. The delay might be due to the vessel sharing the dock not being ready for refloating.
I agree.
@@ElectroRiderSN well shes afloat now! quite a heavy starboard list but afloat..
Agree with above comments but would add that there will most likely be counter ballast in the ship and the flooding of the dock will be very slow and meticulase with many measurements being taken during the process to enable the counter ballast to be shifted as the righting moment nears critical. Was involved with righting and drydocking a sunken icebreaker in the Beufort Sea in the 80's.
It turns out naval architects also know how a ship floats when she is upside down. It took us more than one try but got the job done!
I was at NASCO ship yard for 10 years in San Diego. Reflood the dry dock and the ship will correct itself with the help of the 4 winches that every dry dock has. I am surprised it is taking so long to get this underway.
They won't right the ship until the US Navy is satisfied with 1: their investigation is complete 2: they are satisfied with the procedure to right the ship.
they might have to wait until the work on the other boat in the dock is at a point where it can float again. But yes these things can take ages while the reports are gathered and they work out who is going to pay the bill.
It's NASSCO......... and in my time working with (not for) the Navy... "waiting" is the thing we did most.
It belongs to the government and they don't do anything quick.
My guess is they are trying to get the other ship watertight and ready so they can flood the dock.
That Danish Frigate looks awesome, big as well.
Regarding that Danish ship; what a beauty!
Kudos once again for actually taking the time to give all of us first hand footage and your opinions of how they may refloat this large ship...Have to admit seeing you drone get shot down would have been funny...
Glad to see the drone made it. What a mess that is. Thank you for keeping us posted.
@eSysman SuperYachts • You did an outstanding job explaining what was happening to the ship in dry dock to be righted. From welding plates onto the hull to brackets that will rotate 45° as the ship is righted, you have opened a door onto the complexities of vessel repair & renewal. 👍
Love that the Danish Navy ship is flying the Saltire as a curtesy flag! 🏴
Another interesting one and thanks for taking the time to get up close and personal!
The little kid in me says, 'just flood it and see what happens'. 😆
I'd have flooded it immediately before anyone noticed it had even fallen over. 😎
Dry dock is simply a grown ups bath tub! Just gotta make sure you get all the Gi-Joe's outta the water before pulling the plug!
THANKS ESYSMAN , for a very interesting update 🧐💚💚💚
eSysman, thank you for putting the situation in layman's terms. I look forward to your postings. Please keep us posted on the process of righting the ship.
Hi all,
Tug Captain here in Australia. That vessels stability criteria would allow it to heal over way more than that in very large beam on seas. So flooding the dock would see the forces of buoyancy and gravity working together to right the vessel. The hydraulic jacks are there to hold the keel in correct alignment and aid in the final centre-ing of the keel over the blocks. I’d say divers will be engaged to remove/replace the spacers between the keel and main blocks. The upper straps are there to further secure/align the vessel once moving to the upright position. I doubt they are being used to help right the vessel by winching.
Once the vessel is stable the dock will be drained.
Then the work will start to remove/replace plating and frames creased by the plating coming into contact with the docks walls.
My theory from the beginning was that too many of the upper horizontal props were removed during the painting process to allow access to the plating to apply paint. Moving the props is a common practice after the paint around them has cured. The resultant load from wind and gravity overcoming the remaining props.
Cheers 🍻
Edit: Apparently re floated and out of the dock. I imagine it is cheaper to have it out of the dock for insurance survey than to have it sitting in the dock. Also there would be a back log of vessels standing by/losing money, awaiting their turn in the dock.
Parbuckeling is the term used for this process. Will be interesting for divers detaching things when she's floating.
We said that in the video 👍
thanks for the update on this very interesting incident. keep up the great reporting!
I understand your apprehension about flying your drone but you're a content creator and should be thinking of your audience and how much fun it would be for us to see it get shot down.........lol.
Bet it would bring up the subscription count by a few thousand 😅
@@Jedi.Toby.M yes but would it pay for a new drone?
Exactly
@SAMRODIAN that, my friend, is the question...I don't pretend to understand how this platform works or pays...but if crashing everything from brand new cars, trucks and occasionally a small plane is considered "content" I have to guess the answer is .... possibly...
cheers mate!
Just watched your channel for the first time, and I'm very impressed by your grasp of the scale of the Petrel yard mishap. I'm an ex-USN Sailor, and have seen personally the havoc that unanticipated, violent rolls and other massive movements aboard ships at sea can produce. A sudden, violent, abrupt motion such as the R/
I think your take on how they're going to raise the ship is exactly right flooding the dry dock and pulling it over you basically put a strap under one side of it that's attached to the crane so when the crane lips up it pulls the ship in the direction that you want and then the straps are there to help it so we from both sides you'll be pulling on it one pulling up essentially and the other pulling down essentially it which will be kind of cool to watch I also agree with your assessment that there's likely to be some damage at the very least they've had to weld on they'll have to cut those welds which is an automatic repaint. Assuming there's no other damage sometimes the strap from the crane will have so much pressure on it that can do damage on its own with something that's heavy the forces will be substantial floating it will help a lot in addition if they set up an airbag on the low side it will help they'll probably do all of these things. If you ever want to see the coolest Salvage ever you got to do some research on after Pearl Harbor when they pulled up all those battleships did you know that you was nothing but air! not even airbags just pumped air into various compartments to lift the ship. Footage is out there and its incredible.
Being an idiot myself, I have a lot of experience in fixing my own mistakes. Minimize further damage, go for it, hang on and hope for the best.
Always interesting information. Thanks
The power of the raising water working against the rams holding the keel in the centre of the dock will right the ship as it can't fall over any more to Starboard .The straps will help keep the boat steady as she rights herself. I am sure more straps will be added to the Port side to help maintain the ships position in the dock.
The crane only has 8 axles, so it will be a 500 tonne unit. The Liebherr LTM 1750 has nine axles and is rated at either 750 tonnes or 800 tonnes with the option. the LTM 11200 is rated at 1200 tonnes and also has 9 axles.
The crane is a Liebherr LTM 1650.
@@roundroscoe6502 incorrect, LTM 1500 as said by Peter
Best wishes to Constantin Pogor. I broke my hip/pelvis and can assure you, it's no party. May he heal well.
great footage, that's quite an impressive result from that drone. glad they didn't give you a hard time.
I'm surprised they'd allow you to fly a drone anywhere near those ships.
Great video, thanks for your efforts.
I would expect to see some very large, rubber fenders placed between the ship and the drydock. I guarantee all parties involved are already pissed and don't want more damage.
It's incredible to me that someone didn't ask any questions about clearance when they drained the drydock.
I was a rigger in the Navy, way back. One of my first rig jobs was on a submarine in ARDM-5 ARCO.
That boat was having it's SPM (secondary propulsion motor)removed and reworked. It looked a lot like the unit in your video. When they put the boat in the ARCO, they accounted for it's extension. The skid plate was 5-6ft off the deck.
The unit in your video has 0 clearance, how were they going to work on it?
I would have checked with one of the ships officers for permission to fly the drone.
I never flew over the warship. Kept as far away as possible. Took a very wide route around her.
A US Navy warship is equipped with Phalanx defensive turrets, which, if active, would turn a drone into dust before anyone could say "I see it on radar!" 😂
@@brentboswell1294 That ship is Danish, not US per the content provider. I'm not seeing Phalanx CIWS on board, and they are somewhat distinctive and larger than one would think. CIWS would generally be placed centerline high and unobstructed, or be installed in pairs with one on each side. The thought is to get as close to 360 degree coverage around the ship with a minimum of the swing blocked by the ship itself. Any "dead" areas would need to be unmasked by maneuvering the ship...not a huge issue, but is time spent which you may not have with missiles inbound.
Great video very cool update
Flying a drone around any gray vessel would give me the Willie’s too. Glad it worked out since that’s the only way to get pics there.
Thank you for the concise picture of what is happening! We have few dry docks in Arizona, but I was a master load rigger for 40 years and yes refloating the ship is best providing there has been no latent damage. But they need a better keel block plan than last time. (A bunch of cribbing or dunnage)
The keel block dimensions and placement are actually specified in the original design documents for the vessel. Any substantial changes to the vessel since she was laid down/launched should be reflected in Change Documents, which should include re-calculations of all things related to stability, including keel block design and placement. Consider it the marine version of the padeyes marked "Lift Here" which you have seen a million times.
The hull is strengthened in those areas to allow for the weight of the vessel to rest upon the keel blocks with the proper weight distribution. Placement is critical, as you are supporting the vessel weight upon certain areas, rather than having the water supporting the vessel equally across all points below the waterline as would be the case if she was afloat.
Generally there are also supports specified in locations other than the keel to ensure stability during drydock. My guess is that the cause of the accident will be found here.
We always recondition implement hitches by welding the hitches back to near OEM spec. It takes the right equipment and some shop time but it works well
Park it like you stole it
I hope the injured are taken care of properly and not left to struggle on their own.
Thanks very much for the 4K update on the toppled US Navy Ship my friend from.....
An Old Navy Flying Shoe🇺🇸
If they get grumpy about the drone you do have the distillery behind you...
The crane is for getting things in and out of the dry dock. Those hydraulic rams for example were set by crane. It will not be pulling on the ship. Cranes only pull in one direction ,precisely straight up, any deviation from this along with a list of variables for height to boom top, angle of boom, wind speed and direction and weight of lift can cause a multiple of instant critical fails of structure ( bend crane boom in half) or unbalances (crane falls over and goes boom).
As you mentioned Costa Concordia they used strand jacks for the lateral pull however this ship is smaller and they’re using straps it appears, so they’re going to winch from the side pulling it back straight or at least encouraging it to right itself as the water levels rise. Looks like it might be past the point of self righting in water cause of what has to be a higher than usual CG.
So maybe it could be someone deployed the APU without considering if it would fit underneath whilst in dock, and that at full deployment it could have de-stabilised the vessel enough to cause the 'list' ?
also possible the impact dislodged it, shouldnt but possible
Highly unlikely.
@@sharkeyist Why?
@@Fantic156 operations like extending the thruster are planned and done under supervision. Hydraulics and other sytems would need powering up, with work being done by many trades theres a whole list of stuff that has to be right. Although, theres a boat on its side so someone’s not as fussy as they should be.
@@sharkeyist I know, but it does appear an accident or mistake, despite supervision, occurred for the boat to fall over, and this appears to be the simplest explanation ... Occams razor ...
According the SkyNews the vessel is floating again as of 1500 03/05/23
Twin mk 75, 76mm guns on that Danish ship are pretty sweet.
Interesting about Keel Blocks.
Dockyard expert = Barfly
Idont think additional damage will occur as the pulling cylinders seem to be welded to the hull, I’m not even sure they are cylinders, could be tie bars which are on a hinge to stop the ship moving away from the keel blocks,they seem to low on the hull to be pulling cylinders. it should give some control when the dock is flooded, the straps will be tensioned slowly as the water rises because I guess they are afraid that the boat may “capsize” basically past its Centre of gravity and want to roll towards the quay as the water rises…..the crane is I believe a LTM 1750…800t capacity, probably the only one available at the time to install the equipment at short notice Maybe the plan is to use winches to upright it as they flood the dock. I’ve worked in this specialist industry for a few years and may know the people involved. I will try and get some info…
I hope you can film when they do it. I’m surprised it’s taking so long
Having looked closely at that damaged unit at the front of the ship it looks to me very like a steering propellor very similar to what is used in ships equipped with the "Dynamic Positioning" systems. I worked on the construction of a exploration vessel - The BP SWOPS (Single Well Oil Platform) vessel "Seillean" back in the late 1980's and it had 7 propellors like this. Two Fwrd, three along the midships and two aft. Apart from the two aft propellors, all the others were retractable into the hull of the ship. The idea for them is that all propellors could be extended, rotated and used independantly so as to keep the ship in a single position so that it could conduct its experiments. At the time, figures were quoted of being able to keep the ship in a static position of 30cm.
And so to today. I'm thinking (provided the ship has the dynamic positioning system) that possibly that propellor was accidentally powered up so as to extend below the hull and ended up toppling the ship over. Just an educated guess.
WTF? this is the simplest thing ever, provided her stability is ok (GZ curve) flood the dock, some things will have shifted and she will probably have a list but so what? There are already some damages will a few more matter?, as for certain she will be in dock a very long time now. They are overthinking this problem and I have no doubt some Consultant is making a mint.
Everything is in place for flooding the dry dock im sure that the starboard side has been thoroughly inspected for damage and any breaching repaired by now. The floating should be pretty straightforward. The crane will only assist with taking up weight to prevent her starboard gunnels from swamping. Although with her height i don't see that as an issue. But better to have it at the ready rather than finding out the hard way. Good idea keeping your drone grounded. I don't imagine that they would appreciate their early warning systems alarming the docks 😅👍. But yeah, i have a picture of it in my head lol. Awaiting your update. Thank You.
Although the hydraulic jacks will help stabilize the ship as it begins to right itself (during a reflood), I think it would be prudent to also attach straps to the starboard side in order to better control the ship's topside as it begins to rotate (i.e., to prevent the ship from suddenly snapping quickly to port). Otherwise, any uncontrolled movement may put additional stresses on the hull where the hydraulic jacks are attached.
If there is insufficient access on the starboard side to attach counter-rotation straps, I wonder if there are areas on deck with sufficient strength to weld on some suitable anchor points.
Unfortunate that we cannot see what measures (if any) they have taken on the starboard side of the hull.
Thanks for the video I find that interesting for whatever reason.
0:49 Pshaw, ships going through a inport maintenance period only folks on board are shipyard workers and a few crew standing fire watches.
Sit rep : 2nd May 2023 , Petrel seen afloat and out of dry dock at Leith . Slight list to Starboard .
I think the HSE will make the investigation report public in due course
I was thinking they will have a field day on this one.
Seems like a very logical explanation. Taller Keel Blocks should also be wider and stronger. Who is the contractor ? If Mammoet- they are very skilled at this type of work.
I’m glad you pronounced Petrel properly this time. I also wonder why “past experience” is used given that all experience is from the past, we don’t say round circle after all.
As a former shipyard manager and drydock operator, I surmise that, with the rigging as currently installed, if the graving dock is flooded, the ship will attempt to right itself once flotation is established. If the engineers have calculated the load and its proper placement inside the hull, the vessel will come level when it seeks its center of gravity (CG) afloat..
Keep working. Good luck! 👍
There's no mystery to how it toppled, the high winds put an oscillation into the ship, which called the jacks to loosen and fall, then it cascaded until it fell over.
Wind would only do that if the vessel wasn’t secured properly. Extremely unlikely.
Flood dock and right ship, fix blocks and return ship to the dock. My ship 225 feet long, was in Dubai Drydock sandwiched in with 4 huge vessels, I had sandblast rain for weeks, with my shafts, rudders and sea valves out, the yard needed to flood and let the other ships out, in a day they had blanks on my ship and we moved into another dock. The yards are very capable.
Translated they are waiting for the other ship in the drydock to be completed and when so they intend refloating the capsised one at the exact same time with precaution stability tension from each side of the ship.....thank me later THAT is the fact of the situation......
possibly, but both are now afloat
I worked as a shipfitter in a shipyard building ships for 24 years... I can tell from one look that the cause was total incompetantce by the dockyard people... the ship was not propperly blocked up! They tried to cut corners by not propperly blocking up the bilge keels and tying the bilge keel blocks to the center line blocks... The blocks are suspposed to be made out of concrete five foot on a side... This job was done as cheaply as possible and the whimpy wooden blocks WHICH WERE NOT EVEN SOLID!! on one side were crushed ! Totally nonsense! Someone should be fired because of this. its a miracle no workers were crushed in this accident!!!
Exactly my thoughts. That's what you get when buying cheap dockyard services.
Been working at a ship yard for many years and seen countless docking operations.
Ditto!! Although the hollow blocks are prob cast iron, falmouth has/had some that looked the same, like you say though, theres plenty of stacks instead of tall blocks which is a little suss.
It seems like a fine machine hopefully they'll get it upright and repaired.
That Heli-Deck / Pad is gonna need a bloody bog hammer as well 🤣
WOW! This is the first time I've ever seen something like this. Can't even imagine how horendous it would be if it was a much larger craft, such as a cruise ship. YIKES!
Why cant they simply refill the dry dock, which would right the craft?
Have a look at the refloating of HMS Berkeley Castle on RUclips after the 1953 floods at Sheerness
Sounds like that Danish ship might be listening or already jamming by your audio distortions well filming besides her.
That's exactly what I was thinking too.
Its like morse code but a sharp sound one..
Although it could just interference like when you put your phone / computer near an audio device. Still imagine it's the Danish vessel but not done on purpose
Straps and jacks will keep her from rolling over more as they flood the drydock and then use those to pull her back to an even keel if she's beyond the recovery point. Isn't the first time and won't be the last. As ships get long in the tooth the various modifications and shifting of mass within the vessel can make the plan for blocking no longer sufficient and thus require a new plan if it hasn't been updated. Combine a dated plan that isn't properly accounting for weight distribution with unique blocks and this can happen.
I'm not a Naval Engineer, but personally I'd suggest a reflood of the dry in conjunction with explosives.
The more the better.
Let's face it: The vessel has garnered too much publicity so it can't be used for its covert purpose anymore.
Gotta say, great to see a ytube news channel putting its patreon/ ad revenue monies up on the screen for the viewers. Travelling up and back, and hotels, taxis, drone costs etc. all add up. We get the benefit of the spend. Well done !
The crane is owned by Mammoet, it is a liebherr ltm 1500 8.1 and has a maximum lifting capacity of 500T. It will be there just for preparation for the righting. I very much doubt it will be involved in that process. What it has been lifting looks to be minimal weight as it only has the 3 sheeve hook block reeved 4 times for a maximum lift of 49.6T.
In my opinion and only mine, the orange lifting slings are there as a safety lines that will be anchored back to bollards once the crane is gone and the hydraulic rams will force the keel to the starboard side when the dock is flooded.
It would be interesting to know how for the COG has moved if any of the major components on board have shifted in the collapse.
Bravo! Thanks for the onsite report
That looks as though the APU actually pushed the ship over. When it was deployed it pushed against the floor of the dry dock and continued to push the ship over.
This is going to be a very tricky operation. Flooding the dry dock will be fraught with issues as She is highly unlikely to be at a stable angle of list. Her C of G will be high (no liquids in tanks), and thus GZ will be small and so will GM and She may not want to right on her own. The hydraulic rams will be needed to prevent the keel moving to port, whilst the tails welded on the port side will allow tension to be applied higher up and rotate the ship to port. (The tails are unlikely to be used for parbuckling as they would need to be rigged under the hull on the port side and up the stbd side where they would be pinched between the ship and the dock).
I used to be a plater/burner, ive spent 100’s of hours dock bottom. The dock blocks too high is bs. Those are proper blocks shes on and being that high is nothing unusual. There does seem to be alot of small wedges which concerns me. There should be stacks upto the bilge fins which are not in any pics ive seen. Them not being there put too much load on the side props which were being moved for painting and prob not loaded back up correctly. This is lack of experience and accountability at a office level and a lack of experience at a hands on level not to see and speak up.
Small wedges raising the hight of the boat to accommodate the APU height possibly.
@@eSysmanSuperYachts nah doubt it, ive worked under stuff 3,4m’s up to allow thrusters, stabilisers etc to be removed. Ive never seen or heard of making a hole in dock bottom for thrusters, imagine the civil engineering to put a temporary hole in a water tight concrete box, then work in it? Doubtfull. I can’t remember the logic but the miners and dockgang always told me bigger wedges are better, mayb more area grips/bites/holds better?
Everybody is saying, "It's simple, just flood the dock and refloat the vessel!"
The problem with that is that the APU has been deployed @ 1:53...and will either act as a jackstand, or in my estimation, will snap off allowing a hull breach. No?
It is logical and they are bound to have straps welded to the other side, we just cannot see them yet. Those straps can either be left loose but with only enough slack to stop the boat from going too far to port side. Or they could be slightly slack and then let out slowly as the ship starts to right itself. They will flood the dock most likely.
If you are worried about your drone getting shot down, make sure you've got a camera on the ground going. It'd make a great video!!
Expecting a full tour of the ultra ultra luxurious Britannia while you’re there 😂
It’s planned for the future
@@eSysmanSuperYachts she’s no spring chicken, if you’ve not been aboard before, lower your expectations a few notches first
It appears they will use slings. But a gentler way might be very large inflatable airbags. Just using the crane and slings to steady it.
New supports will be required, hopefully they know now that more stability is required for taller supports.
Someone did not think this through properly.
I couldn't help notice that you've done a couple of posts from your location just outside a distillery. I, for one, will be looking forward to subsequent posts from this perch, which I suspect is in no way coincidental. As the posts progress, perhaps the ship will appear to right itself (at least in footage from the hand-held camera). 😜
Perhaps the dry-dock workers went for a wee dram at lunchtime! 😅
It’s a retractable Azimuth Thruster
If the Petrel has been refloated, now we gotta see what happened in South Africa with that sail boat
She has now been righted and refloated out of drydock.She is moored a short distance away and still has a 10 degree list so there is still work to be done on her.
You missed the bit in the BBC story how the injured worker has Digby Brown representing him, a well known accident claim specialist company.
Ambulance chasers you mean.
Not really. Well respected firm working in the area of accidents and litigation. They have successfully worked for me before.
If you’re allowed to fly your drone over the ship in the first place go and ask to speak to someone on the frigate and just let them know what you’re doing. I don’t think they’re allowed to have weapons armed while in port anyway but just tell them. I don’t think they’d have a problem with it
eSysman "Tower, request permission for a flyby"
Danish Battle Cruiser "Negative Ghostrider, the pattern is full..."
I’m no marine expert but those braces(solid) will keep the ship from shifting further over. I don’t know just how stable it is now. The braces might play two roles. Stabilize the current situation and keep the ship stable during flooding.
The max rating on that crane is with the boom all the way sucked in and picking a load right up next to the outriggers and sometimes not even moving that load. Reaching out over the boat that crane is not going to do anything with that boat. More than likely it's just a support crane to get equipment like those jacks down into the dry dock.
The jacks are set in the bottom just to hold the keel in place while they use those straps to pull laterally. You can see how the straps once they pass the barrier are connected to cables that then go all the way out to the moorings on the other side of the dock that they're using as anchor points. Looks like the cables are also going through some blocks so that they can maximize their pulling force
there was a bigger crane on site that left i beleive on friday... think they needed height and luff to remove things from the deck and lower into the dock, the "ground" either side of the drydock isnt particularly highly rated for taking loads (reclaimed land done a long time ago) so its possible that complicated any lifting
It looks to me as though they are taking the necessary steps to right the ship by flooding the drydock again. The vast majority of the ships weight is currently pressing directly down on the blocking. However when the dock is flooded, the righting moment of the water will shift the resistance to a horizontal force (from the side of the drydock the ship is leaning on) directly to the blocking under the keel. If unchecked, the horizontal force would push the ship off the blocking... My assumption is that the hydraulic rams have been put in place to resist this force. I would venture a guess that the shipyard may also attempt to remove the APU (the one that hit the deck of the drydock) before attempting to refloat the ship.
It's hard to tell from the video, but there seems to be 6 large red cylindrical objects (possibly powerful winches) that may be attached to the 6 straps attached to the hull for a very slow controlled righting of the ship coupled with the floatation from flooding the dock...
Go and say hi to the Danes. They're unlikely to object if they can see what you're doing.
Miltary normally has jammers to keep drones away
JUST FLOOD IT WITH BUD LIGHT🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
The Danish fregat it the design the new UK type 31 is based on.
Why don’t the engineers do a small scale mock up trial, just to see what happens.
That's an expensive oops. Glad I never experienced this in my three dockings.
Your theory as to how and why the boat capsized appears to be so obvious that nobody could challenge it.
Also, anyone who knows you by now knows you are a very intelligent guy, and you show that in all your videos. In this one, you had the obvious foresight to not fly the drone near, much less over, a military vessel. Your good name doesn't need to be compromised, for a RUclips video.
"might be detected" lmao
The dry dock story is interesting but the formidable warship in the foreground took my attention away. Love your videos.
As far as modern warships go, that's a little one...
The red horizontal tubes approx 20-25ft from the rail are winches.
At 5:00... No where near a 1200 Ton crane...
