War Ship: Navy Vessel Heavy Maintenance | Mega Pit Stops | Episode 4 | Free Documentary
Mega Pit Stops - Episode 4: A major overhaul for the danish naval ship: HDMS Absalon!
The most modern warship in the Danish Navy - the HDMS Absalon needs a major overhaul. Every 5 years, the warship is docked, and checked to the bones. This happens in Orskov Yard in Frederikshavn, North Denmark.
The flexible support ship is 137 meters long and equipped with high-precision weapon systems: From torpedoes to machine guns to anti-missile weapons. Thanks to its smooth and angled outer skin, the Absalon reflects only a fraction of radar radiation, making her extremely difficult to detect. The tracking systems of the warship itself, on the other hand, are highly sensitive. Space for two helicopters, two separate engines, bulletproof steel and the most sophisticated technology - all of this is due to be inspected.
The most complex of all the processes: Checking the marine shaft device. Which, in effect, means cutting a hole in the ship to remove the rudder and propellers. The bow thruster is removed and maintained, as well as the sonar - a top secret mission. And then there are the upgrades: The technicians install a brand new UV filter system for cleaning the ballast water; painters give the entire ship a new look. All of this happens under extreme time pressure: the team has only 5 weeks.
But unexpected problems, as well as the special construction of the highly-equippen vessel pushes the engineers to their limits. In this MEGA PIT STOP.

The Danes have been maintaining their warships for countless generations over many centuries. It's in their blood. Such a pleasure to watch their craft and to know that the skill displayed here is just the current iteration. Much respect.
Because a lot of countries stopped cleaning the hull in the water due to the chemicals effecting the bio life / water.
in india, they would have done the same job with a 64 year old wrench, 36 other people watching, and a plastic bucket

This comment should have more likes then it deserves
Sorry to spot the error in your comment. You said India, I presume you meant the UK.
no i meant india@@atrociousliar3314
😜😜 as an Indian. I confirm This. 🤣🤣
"The process is extremely complex, and complicated" That's some great narration there buddy...
@TheBaconHunter haha agreed, but I was mocking the redundancy of that sentence. It's like saying "it's very cold and not warm outside" or "I'm very sleepy and tired"
It's amazing all the planning that goes into this to create create a completed ship. Un"fathomable".
You realize that they weren't building the ship, right?
This is a cup of coffee and it makes the ship SUPER maneuverable!
I am a US Navy veteran (STG1) and retired US Army. The sonar dome is about the most important aspect of a destroyer/frigate warship, if they are an ASW platform. They are huge and the transducers are as well.
Maintenance done by highly professional technicians can add many more years of life into this used warship, aside from guaranteed every component part worked as intended during battle, potentially can save life of those onboard.
Wow that was an unreal documentary. To think they really only covered the most difficult issues and bases on the time and man power everyone only had to work 9 hour days. Amazing!
the 2 things im totally blown away by, #1 the fact that the ship can support itself out of the water on such a small crib under the keel. And #2 were the pneumatic come-along chain winches. How cool are those things?
Agreed..I was thinking the same
You forgot the wooden beams along both sides. Whilst they are partially to ensure the ship stays upright they are more to support the weight of the upper parts of the ship so it doesn't sag laterally around the keel line
I kept thinking how thin the ship's hull looked. Maybe 50mm thick. Seems too thin to be able to withstand any sort of bombardment.
Spent 4 years on a heavy cruiser and have been in dry dock with her. When the ship settles finally on the wooden blocks of the dry dock the entire ship feels absolutely different, not like a ship at all, but more like a sidewalk. One would think that the difference could not be felt because of the enourmous weight versus my 170 pounds, but the difference is felt immediately. I must have had great "sea legs" then.
Congrats mr sea legs
woo hooo. MR SEA LEGS
U want a sealegs medal 🏅
Thank you for your service and for sharing. 🙏
@@81brassglass79 will you not fear Allah
I like how when these documentaries they always increase the pressure by saying if the one thing goes wrong the entire project is destroyed and children will die of the plague and the world will explode.
You're so funny but it's true. No project this big would ever happen without numerous complications.
I've been involved in a lot of submarine and aircraft carrier overhauls. I dont beleive any was on time and on budget.
always waiting for upload from this channel. Who else?
I love that in this hi tech age lumps of wood are so important, long may it continue.
Wow what a beautiful great mechanical engineering work.ship maintenance work explained inch by inch clearly..thank you proude to be an mechanical engineer 🔥🔥😎😎
Very informative and helpful video. Amazing technical skills. Kudos to team work.
the patience skills is incredible
Nato class of the Absalon, is L, which stands for a landingcraft ship. However looking at her, she appears having elements of a fregat, so I wondered if she is a multipurpose ship. Love the name Absalon and according to wikipedia, this is the name of a danish archbishop and statesman living around 1128 and is the founder of the capital city of Kopenhagen. Impressive !
yes it is a fregat / landing craft most danish ships is multipurpose ships because Denmark is a small country with a huge coastline and a lot of islands including Greenland and Faeroe Islands.
Having been involved with tracking and balance of helicopter rotor heads and blades I was totally understanding of their dilemma when they had to measure the track of the propeller shafts, whilst I didn’t have a tolerance of only 3mm I still had tight limits to work to, and when you are trying to get an assembly designed to turn at high speed and move in multiple planes it adds a whole new element of difficulty, but these Rolls Royce guys made their job look like child’s play, but I know different it’s neither child’s play or easy, total respect for their abilities and workmanship. Thanks for sharing this interesting and informative film, awesome pit stop. 😀👍🇬🇧🏴
I was amazed they had that large of a tolerance. I machined prop shafts for US carriers and submarines and the tolerances were generally much less. Looked like they were really only checking runout though.
I've been on several drydocks but my favorite is the floating drydock, It's awesome and can lift an aircraft carrier out of the water.
Superb, professional, highly skilled and impressively competent! Many thanks for the upload.
Halifax Shipyard could have done this but it would have took 2 years and 3 times the original cost.
I love this show
I spent a year in the Philadelphia Naval Shipyard In 1976-77 !! Best time of my life !! I learned how to be a real Boatswain's Mate there .🫡🇺🇸
Y'all should let the narrator do his work. Good job!!
The project manager seems very young for such a responsible job.
Skill set!
Anecdote: Alexander the Great was 19 when he took the throne. Sure, alittle different to be first in line for the crown but obviously he was rather capable during his 14 year reign as conqueror and King. Common misconception that you need to have 30 years experience and have fought both world wars to be able to manage a project like this.
being a mechanical engineer, just loved the video . engineering at its best
Yeh ok buddy thanks for qualifying this video
It's a very best way of explanation that how a ship will be repaired. I really appreciate their efforts for preparing such a good Documentry.
Note the proliferation of "extremely fast and manoeuvrable" phrase they used to describe the ship.
this ship is extremely maneuverable
i have learn a lot through this video, i appreciate the technology and teamwork.👍🏼👍🏼
I like the test using a chalk. The shafts are ready for more hard accecleration!
This channel is LEGEND👊👊👊
Bethlehem steel in Baltimore Maryland used to have a few different dry docks and built and repaired ships. They used winches around the front and side to position the ships. All gone now it's an Amazon.
Very interesting and learned many more new things
Dramatized but enjoyable to watch.. 😊😊
Beautiful video I learned few things from there.
Beautiful Job!
Yes we have a front bow and a back stern too. then there is the under bottom and the upper top... Bloody hell
Just shows how uneducated yhe intended audience must be.
More layers than a cake!
I always wanted to do some kind mechanical job on these ships...that a dream job . great presentation
Removing and servicing of tailshaft assembly is monumental task in a short period of time , and re instate back after full service is completed..
Cool to see those oak beams holding her upright in the drydock, the bulk of the ship makes them look like matchsticks.
Thanks for the good weather
Great awesome video, yard birds do a great job
Everything is a warship, with this narrator...
Why does "6 hours" Denmark need warship who can they fight?
@@0o603 To keep all the beautiful blondes safe?
So many documentarys like this with an american narrator always create fake drama and exageration of everything, its barley watchable, is this style of presenting really popular with a U.S audience ?
Ikr.
I agree, I was like WTF when they explained the procedure for docking the ship in the dry docks I though fuck me here comes a massive over exaggeration of disaster.
That's the yanks for you
IKR! I'm american but gosh that's wayyyyy too much drama!
its for entertainment i believe
I have learn lot of things this video Thanks for your video 👌🙏
otimo documentario ainda mais para quem gosta muito da mecanica .
Vielen Dank allen Inengiering & Projektmanagement Männern & Vätern + Müttern ...Opas & Omas immer ein Glückliches Lächelnd haben & Zufriedenheit am Lebenslänge.....
"This job was not only complicated but very complex" Shit myself laughing
Did ya?
True I was a Combination First Class Electronic Electrician. We did all the lay outs, in some cases help the Cable Pullers to pull some of the cables to speed the process up in the beginning so we can install the equipment foundations and the Cable wire ways. Then we would do what we were hired to do, install the equipment to their designated compartments. Then install the cannon plugs/connectors to the cables. And once the Meggers, Megg out all the cables from having one wire as in the coax cables for TVs and electronic displays to up to 400 conductors/wires. Then after that is completely we would apply power test for proper working condition. Then Sea Trials. But since I was one of a few Technicians that was certified to weld the foundations so I always pulled from the Sea Trial team because the next ship would as usual be late starting it because of agreements on the last minute changes and pay and working details because they were all Union Companies so the different shops. Because of changes made late would have to work those details out. So the starting dates would be late so the foundations had to be laid out and installed with “speed” to make up lost time for contracts that would have to work out. So I would always be pulled to have to install the equipment foundations first once the hulls were coming together. But I enjoyed my job! But my other job skill I had was working on Military aircraft mainly Helicopters but I was also a First Class avionics, electronic and weapons technician on them and on C-130’s, A-10’s and transit aircraft that would land and be passing through or had a failure of some sort. So I was one of a few certified to work on all fixed wing and rotor wing aircraft from all of the other branches of the Military Service. Loved every minute of being a Civilian Contractor!😎
There seems to be some translation problems with the 'marine shaft device' They almost get it right by calling it a propellor shaft but revert to 'axles' towards the end. If you didn't know what it was, you might be seriously confused.
ahh yea the life of a pipe fitter... chain falls and comealongs.. lol whether on land or sea things never change always tight spaces and some of the miracles that get pulled off never fail to amaze me on how so much stuff can get crammed into such small spaces.
This is a good design.
Great job - thanks.
AMERICANS LOVE BEING IMPORTANT
yeah.. AMMERICANS.. but guess what? Big doesnt mean smart :)
I like your baground music, free documentary.

AMAZING HOW BIG THE PROP SHAFTS ARE AND SO PRECISE GETTING THEM OUT AND BACK IN AGAIN.,....
I think he missed out on adding one more "extremely fast and maneuverable" when they took out the thruster :-D
Worst part is the Absalon isn't even remarkably fast for a ship its size. Frigate sized vessels usually can pull 27-30 knots but Absalon can only pull 24 knots ¯\_( ツ )_/¯
No no, He said the 127mm Mark 5 gun, he called it "A MACHINE GUN" It's a 127mm, A tank has a 120mm.
@@Justineexy it is automatic, with about 20 rounds a minute.. kinda is a machine gun
@@OliverFlinn bro, a machine gun is a 7.62 or a 5.56 Gun that can fire about 700-1000 rounds per minute. That Mark 5 127mm gun is about 60 times larger than a 7.62MG. Even if you take a .338 it would still be 40 times smaller than the 127mm. 127mm is the gun used on the arleigh Burke, Capable of hitting a target at over 20miles and can sink a ship with 10 to 40 rounds. The 7.62 Cam even pen a ship..
@@trymetal95 hey, It's the danish man, you gotta consider the fact that Denmark is small, making these ships really is an accomplishment.
Loved the comedy into guys. 👏👏
Awesome engineering
The bow thruster is primarily used for berthing and slipping not manoeuvring at sea.
Thank you!! You saved me from having to type that!!! DD
this whole video is about repairing the prop shaft there saved you 40 minutes
Anything else is military secrets
@@2710cruiser they only had to blur one thing out over 80% of it was about the drive shaft...
👍👍👍
Lol ok
You guys would be surprised how much goes into that ( propshaft) let alone navy vessels prop shaft . Just the transmission component to run it is 64 million dollars plus 500k installment fees The shaft alone has tech in it which makes it sound like a dingy with a 5 hp mercury engine on sonar. But I feel it .. I fall asleep just standing near it on the drydock floor that ish is boring
Thanks
Over dramatic but informative and good content 🙌👍
nice
@tomte47 they are only explaning what can be possible to happen... the Nature and human error is always very crutial for the work's sucess.
The subject was calm and informative but the narrators valiant and dramatic vocal delivery had me on the edge of my seat, holding my breath, wondering will they make it on time?.. Oh no they're 2 days late!... Will the world be safe?..
The difference between European and Anglo North American culture couldn't be clearer than in this tv program. Calm and collected vs dramatic and overhyped. So annoying.
Still amazes me today with all our modern tech we still have to prop up a ship with wood!!!
"It should work, i hope" Now THAT'S the confidence you want when dealing with a multi billion dollar warship!
Nice & good following operation from start to finish very good
Awesome documentary… the narrator’s script is a little exaggerated at points like calling a pump that was testing the propeller pitch a “warship simulator”… it’s entertaining for sure.
Ooh an MTU diesel generator, mean business that!
Awesome engineers! :D
Good narration, Mr. dramatic
They always make it seem more dramatic than it really is.
I like this video keep going 🤠 greeting from Morocco
Hundreds of professionals and thousands of grunts.
great work
I love this job 👍👍 Good job friend 👍👍🙏🙏
The shafts are out in concentricity above the limit of the 3 mm tolerance and so have to be repaired in a marine shaft mfg workshop. How much cost does that involve. ?
At one part it mentioned millions
I’m glad that’s over! My anxiety was through the roof I’ve been eating Valium like m&m’s!
nice video from Bangladesh
That shaft propeller vehicle's cab is hilarious!
Very informative interesting Vedio I like this Vedio -
Out of curiosity, I'd like to know the final bill that the Danish Navy received for all of this work. Also, did they get the customary 10% discount from KZhead?
I watch videos like this and see the extreme precision and measurements that go into something like this. And then I ask myself with all this technology how came man still cannot make a chair that is not lopsided.
Good job 👍🏼
very nice job!
Ooooooh a fellow Dane 👌🏻🇩🇰
Next video: *War Ship: Fixing Helge Instad - Mega Overhaul*
More impressive to see an American Navy Aircraft Carrier in a Drydock.
Yeah, it takes some real COURAGE and POWER to PULL that LEVER! ACTION! DRAMA! ARE YOU READY!? To WATCH a DOCUMENTARY!? 😂
Would've loved for this to be maintence of some old WW2 warships. Alot cooler then new ships.
My dad works in a shipyard and I have pictures of armoured cruiser averof in dry dock
That would be badass, call Richard Branson and Elon Musk so they can time-share a battleship.
Good job.
Good job :)
i love mega pit stop =}
Imagine some dude in the port drives his boat into the ship after all that work. 🤣
Keira Metz then that guy goes bank rupt beceus this ship costs milions
