All language subtitles for Impossible Engineering s10e01 Worlds Largest Crane Vessel.eng

In today's Impossible Engineering... She
is the best, she is the biggest, and

she will remain so.

This is really a mind -blowing vessel.

The world's largest heavy -lift crane
ship.

She's a game -changer because of the
cranes, and they are really on the limit

the engineering possibilities.

Normally in this area you have 1 ,000
cubic meters of liquid gas at minus 160

degrees Celsius.

And the pioneering historic innovations.

I'm currently shifting eight tons.

Feel back at two.

That may be impossible.

Possible.

The planet's oceans can often be a
perilous place to work.

Waves, wind and rain make building
something at sea one of the most

and dangerous engineering tasks around.

Overcoming this hostile environment
takes a vessel with some extraordinary

capabilities.

Enter the Sleipnir.

Named after a mythical eight -legged
stallion ridden by a North God, it's a

154 ,000 -ton heavy lifting crane
megaship that's

redefining how we build at sea.

Sleipnir is the biggest semi
-submersible crane vessel in the world.

Not only in size, length or width, but
also lifting capacity.

We have two of the biggest cranes in the
world on board.

That makes it the biggest and the
baddest.

I believe that the Schleipnir is
absolutely one of the most complex

built floating at sea.

It's big, it's strong, it's fabulous.

Longer than three A380 passenger jets
parked nose to tail.

And wider than the Statue of Liberty
laid on its side.

Beneath the surface, eight gigantic
thrusters propel it through the water.

While almost 165 feet above, on the 130
,000 square foot reinforced deck,

sits its crowning glory.

Two record -breaking cranes.

each capable of shifting the equivalent
weight of the Eiffel Tower, allow the

Sleipnir to build or decommission oil
and gas platforms, as well as install

gigantic wind turbines, all while
floating at sea.

We are now in the central control room.
On all ships you would call this the

bridge. From here we control navigation,
dynamic positioning, ballasting.

safety, fire alarms, and it is the
communications hub of the ship.

It's the responsibility of Captain Arjan
Udo to ensure the safety of the

supersized ship and the 400 workers who
live on board.

Sailing this ship is different from
normal ships. We're one of the widest

in the world. She's very high. Sometimes
we call it an apartment building, only

it's a really fast apartment building.

The sailing in itself is not difficult.
It is all the other vessels around you

that you need to keep an eye on.

That's ferries crossing, people in
sailboats, sometimes an idiot in a

Anything can happen. All you have to do
is watch out the window and don't run

into things.

With a top speed of around 14 miles an
hour, this floating behemoth can cross

the Atlantic in less than a week.

thanks to an innovative fuel system
hidden deep inside its eight giant

At the moment, we are in one of the LNG
tank rooms. Our fuel, the LNG, is

contained inside this tank at minus 160
degrees Celsius.

This is the largest vessel capable of
running on either traditional marine

diesel or liquefied natural gas, known
as LNG.

For Joris Velgers and his team.

This industry first means all new
challenges.

Fuel tanks like these have to be kept at
a low temperature due to the fact that

natural gas in nature is a gaseous form
and we have to condense it into a liquid

to reduce the storage capacity.

For an example, one liter of liquid gas
exposed in gaseous form to 600 liters of

gas.

But keeping a super cold liquid secure
while floating in the middle of the

isn't an easy task.

Looking upstairs, we can see that there
are wooden blocks.

We use wood to prevent the minus 160
degrees radiating outside to the vessel

structure. Because the vessel structure,
if it is touched with minus 160 liquid,

it will become brittle.

Okay.

With the vessel currently empty of fuel,
Joris and his team have a rare

opportunity to venture where very few
people have or will ever go.

We are currently in the LMG tank. This
is a unique opportunity.

Normally in this area you have 1 ,000
cubic meters of liquid gas at minus 160

degrees Celsius.

downstairs two of my men are dismantling
one pump for periodical maintenance the

tank is eight meters in diameter and 25
meters high where we're looking at is

about 23 meters deep in the dungeons

Out on the deck, a large proportion of
the electricity generated by burning the

LNG will be consumed by the ship's two
gigantic cranes, designed in part by

specialist technical superintendent Jori
Brouwers.

So here you have a complete overview of
the crane. The top of the A -frame

is 125 meters above the water, and if
the boom is fully up, It's 170

meter high.

This whole crane is only operated by one
man.

He's sitting in a control cabin
connected to the crane, so he has a good

overview of everything.

It's really amazing engineering.

However, creating such a vast vessel
poses many seemingly impossible

challenges.

How can a floating structure remain
upright as it lifts the equivalent of 35

passenger jets into the air?

To design and build a vessel that can
lift 20 ,000 tons is one of the most

difficult things in the world.

I think you can compare it to sending
someone into space.

How do you engineer a crane that can
rotate even with a load attached?

The loads that occur on the structure,
they are immense.

And keep up to 400 workers safe as they
carry out some of the most dangerous

tasks on the planet.

You have big waves, lots of wind, so
it's really a difficult environment to

these type of jobs.

To achieve this, engineers will need to
draw on inspiration from the pioneers of

the past.

Wow, look at it. What an amazing piece
of technology.

Here it goes.

This is a beautiful system, but it has
one problem.

The door is closed.

I'm so nervous.

This is the Sleipnir.

The largest heavy lift crane vessel in
the world.

Designed to shift gigantic pieces of
energy generating infrastructure.

Its two record -breaking cranes make it
unlike anything else at sea.

Weighing roughly 150 ,000 tons, it's 10
times heavier than the Brooklyn Bridge.

And from the waterline to the top of its
cranes, it stands more than 230 feet

taller than the London Eye.

But propelling a vessel of such
monumental proportion through the water

enormous challenge.

When you're sailing or want to go
sailing, you need to increase power.

Now, all the equipment here is big. This
thruster is 5 .5 megawatts, which is

about 8 ,000 horsepower.

You have eight of those. They are being
fed electricity from the generators.

Those are 12 ,000 horsepower each.

Sleipnir is the most powerful vessel
I've ever sailed on. That's for sure.

Below the central control center, deep
inside the main deck, are the Sleipnir's

four engine rooms.

Hey, can you start engine number 10?

Because we need more power.

Thank you.

Now the pre -lubrication systems are
starting, and then the engine will come

online. And it's up to engineer Joris
Velder to ensure that there's always

enough power to go around.

Very good.

We are currently standing in engine room
number four.

This is nice. It's running.

It's spinning.

In each engine room, we have three
diesel engines with derived generator.

Each engine is good for 8 ,000
kilowatts.

And all together, we have sufficient
power to provide a quarter of the city

Amsterdam for power.

The electrical power is used to propel
the vessel to operate the cranes. We

accommodation for 400 people that also
need electricity. For example, your

toothbrush will also be powered via this
electricity.

Engineers may have found the solution to
propelling this megaship across the

ocean. But once the Sleipnir and its
army of workers get to their

how do they safely lift over 20 ,000
tons without a solid foundation?

It's an enormous challenge for the
ship's designers, headed up by naval

architect Sipke Sherman.

When you're in the middle of the ocean,
of course, you're exposed to big waves,

lots of wind, current.

So when you lift a big load, you want to
avoid any damage. So you avoid damage

by reducing the motions.

How do you do that?

Well, you have to have something
floating. And stable, of course, because

lift something, then it wants to
capsize. Also, you lift it at a point

up, so the vessel wants to tip over, so
you have to provide stability.

Those are the kinds of things you have
to take into account.

To keep a vessel upright in the water
while it lifts loads up to 22 ,000 tons

a monumental challenge.

Potentially you capsize, and actually
that's really what you want to avoid.

To find a solution, the Sleipnir's
engineers must look to the innovations

past.

Engineer Sascha Koschlik is in the
northern German shipbuilding city of

Well, just look at all the cranes over
there. They come in all shapes and

Discovering an innovative piece of
maritime engineering.

Well, look at it. What an amazing piece
of technology.

This is the 177 -foot -tall Long Henry,
or Langer Heinrich, as it's known to the

locals.

I've never seen it from that angle, from
the water. That's just amazing.

One of the oldest surviving floating
cranes in the world, it was

for the time.

Designed in 1905 by German engineers
August Beschum and Theodor Kietmann.

The Long Henry's arched shape allowed it
to reach further than other cranes of

the time, while an ingenious system
hidden deep within its pontoon allows it

lift 100 tons without capsizing.

To demonstrate, Sascha has prepared an
experiment.

Now here I've got my crane attached to a
pontoon, just like in the background

with the Langer Heinrich. And if we put
that in the water now like this, It's

floating nicely, upright, it's perfectly
balanced, right?

But if I put a little bit of weight onto
the boom, and I've got here prepared a

little bucket with some rocks in here,

if I attach that, then the whole thing
will just tilt over.

And it will end up in a complete
disaster, as you can imagine here,

So what can we do in order to
counterbalance it again?

We need to put weight onto that side of
the vessel.

And what better is there to use than
actually the water in which we float? So

I've prepared here two ballast tanks,
basically, one that is only partially

filled that goes onto the front, and
we've got one which is almost filled

goes onto the back of the vessel.

So we put that here, and the other one
goes right here.

Here we go.

If I now add the load to the front, what
we can see is it floats upright and

it's nicely balanced.

And that's exactly what they do in the
Lange Heinrich.

On board, nine ballast tanks hidden deep
inside the pontoon of the Lange

Heinrich can be filled with over 200
tons of ballast water.

Wow, this is amazing.

We're now right in the belly of the
crane.

We've got ballast tanks behind those
walls on either side. And everything was

done by that tiny little pump here on
the side, which has one horsepower,

actually. And with all those pipes you
can see here, you could move the ballast

water to either side of the vessel,
depending on what you actually wanted to

lift.

Having served in shipyards in Poland and
Germany, and after over seven decades

of service, the Long Henry was finally
retired.

It's quite amazing to think that it has
worked throughout the two world wars and

has been shipped around Europe, and yet
here it is still floating, and when you

look at it, it looks almost as good as
it did the day it was built.

Back in the Netherlands, engineers have
taken the concept behind the Long Henry

and enlarged it to

astronomical proportions.

Schleidmere is the biggest crane vessel
on Earth.

It's 100 meters wide, 220 meters long,
and to the top of the crane, 200 meters

high. The size of it, it's really
amazing.

to ensure it doesn't capsize during a
lift.

Engineers have designed an equally
supersized solution to balance the load.

Underneath the waterline fit the ship
two giant pontoons.

Inside them, 82 ballast tanks can be
pumped full of water, adding more than

weight of an aircraft carrier to the
vessel and sinking it to a maximum depth

almost 120 feet.

The deeper it sits, the more stable it
gets.

And also when we lift big weights, we
need to have counterbalance basically,

which we do with water balance.

Once the team is out in the middle of
the ocean, It's the responsibility of

Captain Arjan Udo to ensure that this
process runs smoothly.

This is where we do all ballast
operations for the vessel.

What you see here is an overview of the
port side of the ship and then the

ballast system. So you see tanks,
pipelines, and here you have what we

pump room with the ballast pumps.

And the ballast pumps we use to get
water in and out of the ship.

Now we are 140 million kilos.

When we're at working draft, 32 meters,
it's almost 300 million kilos.

That makes the ship more stable for the
lift operations.

The ballast system on the Sleipnir is
designed big, actually so big that we

fill an Olympic -sized swimming pool
inside five minutes.

In total, Captain Udo can pump on board
almost 210 ,000 tons of seawater.

But this ship has a party trick.

and that is our dynamic ballast system.
We can use it to balance the loads that

we pick up better.

And basically you have a connection in
the hull, water comes in, you use the

pump to put it on the right location,
open the same valve, and you discharge a

lot of weight very quickly.

And that means we can use the ballast to
balance the loads on the vessel better.

On board, 16 dynamic tanks allow the
Sleipnir to continuously adjust its

Ballasting is controlled sinking.

Sinking is something you tend to avoid
on a ship. It always gives you a weird

feeling.

This sophisticated system is key to
Sleipnir's lifting capacity.

But it's just one of many creative
solutions necessary to make this one -of

-kind vessel sail.

To overcome some monumental challenges.

Lifting a load is only half of the
battle.

Engineers will look to innovators of the
past.

The world around us will be a very
different place without this ingenious

component.

Kira Misleipnir is a marvel of
engineering.

The largest ship crane in the world.

capable of lifting the weight of 20 ,000
cars at once.

The vessel's dynamic ballast system
allows operators to finely tune depth

stability as they handle some of the
largest lifts in the world.

Many decks below the control center,
deep inside one of the giant pontoons,

it's up to engineer Joris Velders to
ensure that this controlled sinking

system is in perfect working order.

At the moment, we are in one of the
ballast tanks of the Sleipnir.

The particular ballast tank is one of
the biggest, and it is about 6 ,000

meters in size.

And to give you a reference, this
comparison would be two times an Olympic

swimming pool.

It's unbelievable.

There are a few ways to fill it up. You
can do it with free flooding by just

opening the valves, and then by gravity,
they fill up.

We also have eight...

ballast pumps, and these pumps can also,
at high speed, fill it up.

And getting the vessel empty to get a
sailing draft again, we use the same

to pump it out again.

This vessel, when sailing, has a draft
of around 12 meters. If we are doing

normal operations, we can go to 32
meters.

The dynamic ballast system maintains
vertical stability.

But Captain Udo and his team also need
to maintain Sleipnir's geographic

orientation once the enormous vessel is
in place.

At sea, you have influence on the ship.
You have wind, you have waves, you have

current that tends to move the ship.

But when you're building a platform, you
want to stay in the same position.

To do this, they rely on advanced GPS
and sensor information.

We keep the Sleipnir in position by
handing control of the thrusters to a

computer system.

So it calculates forces on the ship, and
then it calculates a solution, how it

should get from where it is to where it
needs to be.

The accuracy of the system on a ship of
this size is within 30 centimeters.

If there's a bit more wind, maybe 50
centimeters.

It stays within that footprint for weeks
on end if you want to.

But once in position and ready to lift,
the team faces another challenge.

The ship's two vast cranes need to be
able to rotate 360 degrees, even with

10 ,000 tons hanging from them.

It's up to Technical Superintendent Jori
Brouwers to find a solution.

So to lift 10 ,000 tons is even more
impressive if you consider the forces

occur on the structure, they are
immense.

Lifting a load is only half of the
battle.

When you have the load lifted, you also
need to be able to rotate the cranes to

position the load where you want to put
it.

So how do you rotate a crane with such a
heavy load attached?

Could a solution be found in the
innovations of the past?

All right. Take her up, Paul.

Physicist Susie Sheehy is in the heart
of the English countryside, finding out

if she's got what it takes to be a
miller.

Wow. Well, it's a great view up here.

I can really feel the wind when I get up
this high.

And discovering an engineering solution
hidden in an unlikely location.

So on these big structures, this wind,
I'm going to try and put one of these

enormous canvas sails so that the
windmill can catch the wind.

Built in 1632, Chesterton Mill is one of
the oldest operating examples left in

the country.

The wind is up, so I think we're going
to give it a spin. So, Paul, can we head

back up? Thank you.

We're excited to see this turn,
actually.

Oh, here it goes.

So at the moment, the wind is coming in.
It's hitting the sails.

They're tilted at a slight angle, and
that creates this turning motion, which

really quite beautiful.

But it has one problem, and that is as
soon as the wind changes direction, it's

going to grind to a halt.

So what we're going to need to do...

is change the direction of the windmill
so that we can pick up the wind again

and keep going.

But how do you rotate a structure that's
fixed firmly to the ground?

The solution lies in an ancient
innovation.

In 1588, Italian engineer Agostino
Ramelli published designs for over 100

devices capable of pumping or raising
water from wells.

And deep in his sketches, lies the
solution to the wind problem faced by

engineers at Chesterton Mill.

Oh, wow.

Oh, this is great.

So I'm now right at the top of the
windmill structure, and over my head is

cap. To get it operating in an optimal
way, we need as much wind as possible,

which means we need to rotate the cap
towards the direction of wind.

But that's not going to be easy because
this is a massive, heavy wooden

structure.

Weighing a whopping eight tons, rotating
the cap is only possible thanks to

Ramelli's ingenious solution.

So the way it works is there are two
rings around the outside, one here

to the cap on the roof and one attached
to the mill, and in between are the

rollers. So what this system allows is
that the cap, which is circular, can

rotate while the mill stays still.

Inside the cap, the giant wooden roller
bearing connects into a system of gears

that allow the miller to manually rotate
the position of the sails.

Ensuring no matter what direction the
wind is blowing, the mill is always

operating at optimum speed.

Right, so let's give this a go. So if I
turn this wind, it's going to turn the

gear system, transfer through here, and
hopefully we'll turn this eight -ton

cap. above my head.

Apparently, it takes about 20 minutes
for someone stronger than me to

turn the cap through 90 degrees.

I don't think I like that one.

I'm currently shifting eight tons with
this.

Oh, it feels like it too.

Oh, there's no way I could have been a
miller.

Romelli's designs were instrumental to
the development of the roller bearing.

An innovation that has helped shape the
modern world.

The roller bearing is an essential
engineering component that most of us

take for granted today.

But it's used in manufacturing, in
construction, in the energy sector. The

around us will be a very different place
without this ingenious component.

From a 17th century mill to the biggest
and most advanced ship crane in the

world. The team behind Sleipnir.

This roller bearing is the biggest in
the world.

Will need to take Ramelli's idea and
supersize it.

When you see it rotate for the first
time, it's really impressive.

17th century visionary Agostino Ramelli
inspired the roller bearing system that

makes the remarkable rotating cranes on
Hirama Sleipnir possible.

On board the Sleipnir, Jori is getting
up close to the world's largest

incarnation of Ramelli's innovative
technology.

So now we are inside the crane top,
which is the connection piece of the

to the crane.

And next to us, we see the roller
bearing.

Yeah, which makes it possible for the
crane to rotate.

This roller bearing is the biggest in
the world and has a diameter of 30

It's really a unique piece.

So the whole roller bearing is built up
from segments, and within the bearing

there are...

5000 small roller elements that make it
possible for the crane to rotate.

The bearing consists of two rings.

The lower section is connected to the
vessel, while the top is joined to the

bottom of the crane.

When the rollers are added, the system
allows 360 degrees of rotation.

In the past, on similar cranes, bogey
wheels were used, where the crane

on like a train track.

But that means that you will use a lot
of steel and reinforcement.

So by going back to the roller bearing
design and just expand the size, we made

it possible to rotate the whole crane,
which weighs 9 ,000 tons, very smoothly

on the bearing.

And actually the crane can rotate within
two minutes.

By implementing the roller bearing
system, the team has made it possible

two main cranes on board to be able to
lift more than they weigh.

When you see it rotate for the first
time, it's really impressive.

Alongside the roller bearing, over 40
miles of steel rope allows the Sleipnir

lift loads 420 feet into the air.

allowing giant structures to be built at
sea faster than ever before.

And floating off the coast of Israel,
Sleipnir recently attempted her toughest

lift to date.

After days of planning and positioning,
a vast platform weighing a massive 16

,860 tons was successfully raised.

And then moved into place.

Setting a new world record for a
floating crane lift.

That's incredible. You hear the engines.

You see the boom going up.

It's just amazing.

Engineers may have built the two most
capable cranes at sea, but now they face

their most important challenge.

Safety of the crew on board is the most
important thing to us.

But keeping up to 400 crew members safe
in these difficult conditions is a major

challenge.

We are exposed to different risks. We
work on a ship that moves. It's at sea,

you can have bad weather.

We lift very, very heavy things.

We work with heavy equipment.

We work with big cranes, so we are
exposed to a lot of different risks that

won't face on shore.

If we have to abandon ship, yeah, then
we are faced with a big problem.

Because getting people off a ship at sea
in an ocean is one of the more

difficult things there is.

It's a problem that's made much more
difficult when your deck is situated

100 feet above the waterline.

Jumping in the water from this height of
the ship, That's really a lost resort.

The absolute lost resort.

So could a life -saving solution lie in
the innovations of the past?

Launching in 5, 4, 3, 2, 1, go!

The Hirama Sleipnir, a billion -dollar
heavy -lifting crane megaship, capable

traversing the planet's oceans and
lifting the equivalent of over 30 A380

passenger jets.

It takes up to 400 crew members to
operate this monster vessel. And in the

of a disaster at sea, they need a way to
safely escape.

But with the deck often situated up to
115 feet above the water, the usual

lifeboat launch system isn't an option.

In Cork, in the south of Ireland, deck

officer Stephanie Hyde is discovering
another mechanism that's been in use for

over 100 years.

It offers an alternative to open -top
lifeboats that are lowered mechanically.

On a vessel as big as the Sleipnir, the
time it takes to discharge a lifeboat

using a winch could be the difference
between life and death.

This type of escape system obviously
works, but as ships and facilities got

larger and even more dangerous,
engineers had to find a system that got

faster and farther away from danger.

Luckily, one man was working on a
solution.

In the 1960s, Dutch marine engineer
Joost Verhoef designed an ingenious new

system for saving lives at sea.

So this is what Verhoef came up with.

It's a fully enclosed, free -fall
lifeboat.

By opting for a gravity -powered launch,
Verhoef's design was capable of getting

people to safety faster than ever
before.

When the ship is at sea, this hook here
is the only thing keeping the boat

secure.

Once the coxswain pulls the release
handle, this hook will go up and release

lifeboat into the sea and away from
danger.

And by fully enclosing the boat,
escaping crews were protected from fire

falling debris.

So this is the inside of a free -fall
lifeboat. On my right -hand side here,

have the coxswain seat, where he can
start and stop the engine. It also has

own self -contained air system.

So in the event of the ship being on
fire, we'll be able to breathe in fresh

rather than any toxic gases or smoke.

which may be coming from the outside
environment.

The great thing about this design of
lifeboat is that it's much safer and

much more efficient.

As soon as you press the release handle,
you're in the water and you're away

from danger straight away.

But this increased speed of launch
creates a problem when the lifeboat

water.

When the coxswain is happy, he'll pull
the lever and release the lifeboat,

will travel at a very high speed into
the water. It is possible that it will

capsize, but there's a ballast system in
it that will ensure it always rights

itself afterwards.

Situated in the hull of each boat,
liquid -filled ballast tanks and

foam ensure that however the vessel hits
the water, it always rights itself to

the correct position.

To understand the engineering brilliance
behind Bear Hoof's design, Okay, I'm

all strapped in.

Stephanie is strapping in for a brief
but extreme ride.

I'm so nervous.

The door is closed.

So we're almost ready to go.

Launching in 5, 4, 3, 2, 1,

launch!

Oh my God, that was unreal.

We went fully under the water.

We can now get away from danger really
fast and safely.

You see, we're in seconds. We're about
100 metres away from the jetty already.

Much faster than if we were using the
open lifeboat.

It's tough. Can be used in all weather.

And most importantly, it gets you out of
danger quickly.

That was so much fun.

What an amazing piece of engineering.

This pioneering lifeboat system has been
in use on oil rigs and large merchant

ships since the 1980s.

But to outfit the Sleipnir...

Of course, we hope that we never have to
use these boats for real.

Engineers will push Barehoof's
innovation to its limit.

There's no free -fall lifeboat that has
been launched with people from this high

up.

Inspired by Dutch inventor Joost
Barehoof, the free -fall lifeboat system

board mega -crane Hirama Sleipnir is one
of the most advanced in the world.

Should Arjan and the crew need to
abandon ship, a fleet of free -fall

is ready to ensure their safety.

We are here at lifeboat station 123, and
what you see here are our free -fall

lifeboats, our means of escape in case
of an emergency.

If we launch this lifeboat, With people
inside, we would be breaking a world

record. Because no free -fall lifeboat
has been launched with people from this

high up, which is about 55 meters at the
moment.

Located above the deck, nine free -fall
lifeboats with space for a total of 630

people are ready to launch 24 hours a
day.

Of course, we hope that we never have to
use these boats for real.

We only exercise with them. We don't
want to use them in real life.

Each lifeboat is equipped with the
essentials to survive at sea.

These lifeboats come equipped with quite
a few things.

There's water inside.

There's food inside.

There's also fishing tackle inside.

There's means to rescue, to alert
people. There's a radio.
