the UK has forged its own pathfrom the rest of the continent.
18
00:01:20,240 --> 00:01:25,800
It's made up of England, Scotland,Wales, and Northern Ireland.
19
00:01:27,280 --> 00:01:33,160
Each country has its own unique landscape,culture and sense of identity.
20
00:01:35,880 --> 00:01:39,800
It's April, and across the nationthe weather is warming up.

A bird's-eye viewreveals how this 2,000-year-old city
25
00:02:07,520 --> 00:02:12,040
is densely packed with unique architectureand engineering wonders
26
00:02:12,480 --> 00:02:14,480
seen nowhere else on Earth.
27
00:02:15,440 --> 00:02:19,080

00:02:40,680 --> 00:02:44,960
A sprawling metropolis stretching around50 kilometers across.
33
00:02:46,040 --> 00:02:48,480
It's home to around nine million people.
34
00:02:52,520 --> 00:02:54,560
Zooming in on the city's heart
35
00:02:55,800 --> 00:02:58,280
reveals a cluster of high tech buildings
36
00:02:58,720 --> 00:03:01,680
that soar aboveLondon's traditional landmarks.
37
00:03:04,400 --> 00:03:08,880
These are the towering skyscrapersof London's famous financial district.
38
00:03:11,400 --> 00:03:15,560
Each stunning new mega structurehas a uniquely engineered form.
39
00:03:18,640 --> 00:03:20,320
Perhaps the most striking
40
00:03:20,400 --> 00:03:23,160
is the giant glass cladLeadenhall Building,
41
00:03:24,720 --> 00:03:27,720
famous for its unusualwedge-shaped design.
42
00:03:30,080 --> 00:03:34,560
This breathtaking structureis 225 meters tall.
43
00:03:36,160 --> 00:03:40,000
Its steel core weighs almost 18,000 tons.
44
00:03:42,120 --> 00:03:47,480
And 4,220 glass panelscover its angled facade.
45
00:03:55,080 --> 00:03:57,920
Pawel Urban is more familiar than most
46
00:03:58,000 --> 00:04:00,880
with the Leadenhall Building'sshining glass panels
47
00:04:01,280 --> 00:04:04,520
because it rests on his shouldersto clean them.
48
00:04:05,400 --> 00:04:09,080
I prefer to doing this job
when it's sunshine like this.
49
00:04:09,480 --> 00:04:10,520
Nice weather.
50
00:04:12,320 --> 00:04:16,200
NARRATOR: Today, Pawel and his creware cleaning the Leadenhall Building.
51
00:04:18,000 --> 00:04:22,120
To do this, the team usesa specially designed mechanical arm
52
00:04:22,520 --> 00:04:25,480
which carries a metal cradledown the side of the building.
53
00:04:27,680 --> 00:04:29,920
But the team can only go over the edge
54
00:04:30,240 --> 00:04:33,480
when the wind speedis less than 40 kilometers per hour.
55
00:04:35,240 --> 00:04:39,040
This is to make surethe cradle doesn't swing precariously
56
00:04:39,120 --> 00:04:41,680
in the strong breeze and damage the glass
57
00:04:42,960 --> 00:04:45,840
or come detachedfrom the crane altogether.
58
00:04:48,720 --> 00:04:52,520
The wind has been howlingat over 50 kilometers per hour all morning
59
00:04:54,320 --> 00:04:56,520
but the crew notice a lull in the weather.
60
00:04:57,840 --> 00:04:58,720
URBAN: Not windy.
61
00:04:59,600 --> 00:05:00,960
Only three miles.
62
00:05:04,080 --> 00:05:07,720
NARRATOR: The team get the go-aheadto begin their extraordinary descent
63
00:05:07,800 --> 00:05:10,000
down the face of the glass skyscraper,
64
00:05:11,040 --> 00:05:12,560
but they need to work quickly
65
00:05:13,040 --> 00:05:15,200
to make the most of this lucky breakin the weather.
66
00:05:16,760 --> 00:05:19,080
URBAN: The first timewhen I was in the cradle,
67
00:05:19,160 --> 00:05:21,800
I was very scared but now I'm all right.
68
00:05:23,960 --> 00:05:28,200
NARRATOR: Aerial cameras revealthis extraordinary process up close.
69
00:05:35,760 --> 00:05:39,240
Unchecked, the furtherthe cradle drops on its cables,
70
00:05:39,560 --> 00:05:41,800
the more it risks swinging in the wind.
71
00:05:43,960 --> 00:05:47,320
So architects built this skyscraperwith seven channels
72
00:05:47,400 --> 00:05:49,560
running down the south faceof the building.
73
00:05:52,040 --> 00:05:55,880
The cradle has specially designed railsthat lock into these channels.
74
00:05:57,960 --> 00:06:00,960
The rails help stop the cradleblowing in the wind.
75
00:06:03,560 --> 00:06:05,280
But as the hours tick by,
76
00:06:05,600 --> 00:06:09,000
spring's unpredictable weatherstarts to turn.
77
00:06:10,960 --> 00:06:13,040
URBAN: Sometimes it's very windy
78
00:06:13,120 --> 00:06:16,840
and we have to go up quick'cause it's very dangerous for us.
79
00:06:18,160 --> 00:06:20,080
NARRATOR:
With the wind picking up further,
80
00:06:20,440 --> 00:06:22,720
Pawel and his teamfinish their last window.
81
00:06:24,480 --> 00:06:27,240
They've managed to completetwo sections of the building
82
00:06:27,320 --> 00:06:29,240
in the short time they've been cleaning.
83
00:06:29,840 --> 00:06:34,320
But with the Leadenhall Building's4,220 panes of glass,
84
00:06:34,880 --> 00:06:38,040
it's a full-time jobto keep the city's skyline glistening.
85
00:06:39,040 --> 00:06:40,160
URBAN: Well, see the windows.
86
00:06:40,240 --> 00:06:41,520
We are on ground floor.
87
00:06:41,600 --> 00:06:42,560
Nice and shiny.
88
00:06:42,640 --> 00:06:43,520
Nice and clean.
89
00:06:43,600 --> 00:06:45,120
So I'm very proud and happy.
90
00:06:45,680 --> 00:06:46,840
We're doing a good job.
91
00:06:49,880 --> 00:06:53,960
NARRATOR: As London's daredevilwindow cleaners climb down from their rig,
92
00:06:55,640 --> 00:06:57,240
across the Irish Sea
93
00:06:57,600 --> 00:07:00,880
it's time for anothermega-sized spring clean.
94
00:07:03,440 --> 00:07:07,240
Northern Irelandis the United Kingdom's smallest country.
95
00:07:09,200 --> 00:07:14,200
Belfast, the country's capital,is a port city steeped in history.
96
00:07:15,800 --> 00:07:18,760
Home to the world-famouslaunch site of the Titanic.
97
00:07:21,440 --> 00:07:24,400
Northern Ireland is a landof epic landscapes
98
00:07:24,800 --> 00:07:28,560
from rugged countrysideto mythical coastlines.
99
00:07:31,120 --> 00:07:33,840
On its northeast coast,in County Antrim,
100
00:07:34,520 --> 00:07:36,040
sits a natural wonder.
101
00:07:37,480 --> 00:07:41,280
This jet-black shorelineis called the Causeway Coast.
102
00:07:42,240 --> 00:07:45,600
It's a 60-million-year-oldgeological marvel.
103
00:07:48,280 --> 00:07:52,720
A bird's-eye view revealsa world-famous part of this coastline
104
00:07:52,800 --> 00:07:54,400
called the Giant's Causeway.
105
00:07:56,520 --> 00:07:59,560
It's a bizarre lattice of around 40,000
106
00:07:59,640 --> 00:08:03,200
60-million-year-oldinterlocking hexagonal pillars.
107
00:08:06,560 --> 00:08:11,200
The Giant's Causeway is Northern Ireland'smost visited tourist attraction.
108
00:08:12,240 --> 00:08:14,160
But because it's nearthe busy shipping lanes
109
00:08:14,240 --> 00:08:15,920
of the Atlantic and Irish Sea,
110
00:08:16,800 --> 00:08:19,760
the coastline encountersa lot of marine debris.
111
00:08:22,280 --> 00:08:24,200
This means that every year,
112
00:08:24,280 --> 00:08:27,400
the Causeway Coastis in need of a spring clean.
113
00:08:29,400 --> 00:08:31,200
ETHERSON: Today we're gonna seewhat we can do
114
00:08:31,360 --> 00:08:32,800
at removing a lot of the plastic
115
00:08:32,880 --> 00:08:34,520
that's in the bays here
at the Giant's Causeway.
116
00:08:35,640 --> 00:08:39,040
NARRATOR: Barry Ethersonis a local water sports instructor.
117
00:08:39,800 --> 00:08:42,640
He's part of a dedicated groupof volunteers
118
00:08:42,720 --> 00:08:46,440
who clear up unsightly marine rubbishfrom the Causeway Coastline.
119
00:08:49,000 --> 00:08:53,720
Today, Barry and the teamaim to clear four kilometers of coastline
120
00:08:53,800 --> 00:08:55,560
around the Giant's Causeway.
121
00:08:55,920 --> 00:09:00,000
Picking up everythingfrom nylon fishing nets and car tires
122
00:09:00,400 --> 00:09:03,840
to plastic oil drums and even flip flops.
123
00:09:05,160 --> 00:09:07,320
But the seaweed and hidden rocks
124
00:09:07,400 --> 00:09:10,120
make it too dangerousfor boats to get close enough.
125
00:09:11,440 --> 00:09:13,800
So the team turn to jet skis.
126
00:09:18,280 --> 00:09:22,320
The final few metersare too shallow even for the jet skis.
127
00:09:23,640 --> 00:09:26,360
So the volunteers must swimthe last stretch.
128
00:09:27,600 --> 00:09:31,680
Careful to avoid the biggest wavessmashing against the rocky outcrop.
129
00:09:34,160 --> 00:09:37,760
According to local legend,a giant called Finn McCool
130
00:09:37,920 --> 00:09:40,520
built these pillarsas a bridge to Scotland.
131
00:09:42,880 --> 00:09:47,200
In truth, the Giant's Causewayis the result of a volcanic eruption
132
00:09:47,280 --> 00:09:49,080
sixty million years ago.
133
00:09:50,480 --> 00:09:53,000
As lava bubbled out of the ground here,
134
00:09:53,080 --> 00:09:55,720
it hit the sea where it cooled quickly,
135
00:09:56,400 --> 00:10:00,000
cracking to form the perfecthexagonal-shaped basalt pillars
136
00:10:00,080 --> 00:10:01,280
we see today.
137
00:10:07,480 --> 00:10:12,760
It takes Barry's team around six hoursto collect more than 500 kilos of litter.
138
00:10:13,400 --> 00:10:14,200
(Barry grunts)
139
00:10:14,280 --> 00:10:15,160
(yells)
140
00:10:16,200 --> 00:10:19,760
Now, they need to get their haulback to the boat.
141
00:10:23,880 --> 00:10:27,760
Barry and the volunteersedge their litter sacks to the shoreline.
142
00:10:30,240 --> 00:10:33,160
The team need to scramble backto the jet skis
143
00:10:33,240 --> 00:10:35,400
fully laden with their bags of waste.
144
00:10:36,520 --> 00:10:38,880
A lot of the big sacks,
they-- they catch and everything.
145
00:10:39,040 --> 00:10:41,080
They get caughtin the barnacles and limpets.
146
00:10:41,640 --> 00:10:43,360
Yeah, it's just brute force really.
147
00:10:43,440 --> 00:10:44,720
Egging each other on.
148
00:10:46,440 --> 00:10:48,200
NARRATOR: Clearing the area of litter
149
00:10:48,280 --> 00:10:52,920
is about more than just safeguardingthis region's extraordinary aesthetics,
150
00:10:53,000 --> 00:10:55,800
it's about keepingthe ecosystem healthy, too.
151
00:10:56,480 --> 00:10:58,920
ETHERSON: Plastics break downinto micro plastics.
152
00:10:59,000 --> 00:11:02,120
That gets into the fish.It gets into, inadvertently, people.
153
00:11:05,400 --> 00:11:09,120
NARRATOR: The volunteers load the trailerwith their final haul.
154
00:11:09,520 --> 00:11:14,480
They've managed to collectan impressive 545 kilos of rubbish.
155
00:11:15,760 --> 00:11:19,080
Today's effort has helped preservethis iconic coastline
156
00:11:19,160 --> 00:11:21,720
in time for the influx of summer tourists.
157
00:11:22,280 --> 00:11:23,880
ETHERSON: There's a lot of people herewho care.
158
00:11:23,960 --> 00:11:25,320
We appreciate it for its beauty.
159
00:11:25,400 --> 00:11:26,480
We work here.
160
00:11:27,720 --> 00:11:29,280
You kinda hope it stays beautiful.
161
00:11:29,640 --> 00:11:30,880
This is a very busy part of the world.
162
00:11:30,960 --> 00:11:31,960
A lot of people come here.
163
00:11:32,040 --> 00:11:33,320
For everybody to enjoy.
164
00:11:38,800 --> 00:11:40,360
NARRATOR: It's the beginning of June
165
00:11:40,840 --> 00:11:43,560
and the temperature across the nationstarts to rise.
166
00:11:45,320 --> 00:11:48,400
Once empty beaches fill with tourists,
167
00:11:49,640 --> 00:11:51,560
as holiday makers flock to the seaside.
168
00:11:54,080 --> 00:11:57,040
Summer has arrived in the UK.
169
00:12:01,280 --> 00:12:03,360
In this warm, glowing weather,
170
00:12:03,440 --> 00:12:05,920
England's south coast fills with tourists
171
00:12:06,440 --> 00:12:08,600
seeking a traditional family break.
172
00:12:09,840 --> 00:12:12,080
From the white chalk cliffs of Dover,
173
00:12:14,040 --> 00:12:16,080
to Dorset's Jurassic Coast,
174
00:12:16,600 --> 00:12:18,160
these picture-perfect bays
175
00:12:18,720 --> 00:12:21,400
echo to the soundof an engineering masterpiece
176
00:12:21,960 --> 00:12:23,400
that changed the world.
177
00:12:25,760 --> 00:12:31,080
In the 19th century, British engineersinvented and perfected the steam railway.
178
00:12:34,480 --> 00:12:39,320
They laid more than 32,000 kilometersof track across the British Isles,
179
00:12:40,400 --> 00:12:42,320
revolutionizing transport.
180
00:12:43,640 --> 00:12:45,440
On the South Devon Coast
181
00:12:45,760 --> 00:12:48,280
lies perhaps the mostbeautiful railway line
182
00:12:48,360 --> 00:12:51,720
Britain's industrial innovatorsever conceived.
183
00:12:56,440 --> 00:12:59,440
This is the Dartmouth Heritage Railway.
184
00:13:00,360 --> 00:13:04,480
It's 11 kilometers of linestretching from Paignton in the north
185
00:13:04,640 --> 00:13:06,320
to Kingswear in the south.
186
00:13:07,400 --> 00:13:12,120
The railway offers nostalgic touristsa brief taste of a bygone age.
187
00:13:15,360 --> 00:13:17,080
It's up to Ian Wellington
188
00:13:17,160 --> 00:13:19,800
to keep the railway's collectionof vintage steam trains
189
00:13:19,880 --> 00:13:21,040
in perfect running order.
190
00:13:24,280 --> 00:13:28,680
Each of these machineshas its own unique character and nuances.
191
00:13:29,280 --> 00:13:31,280
WELLINGTON: Some people saythey've got a personality.
192
00:13:31,760 --> 00:13:33,000
They are living and breathing
193
00:13:33,080 --> 00:13:36,240
because of how they work
and the way they sound.
194
00:13:39,080 --> 00:13:42,400
NARRATOR: These vintage machinesrun on hot steam
195
00:13:42,480 --> 00:13:44,400
held at incredibly high pressures.
196
00:13:45,640 --> 00:13:50,480
The six engines in Ian's carehave a collective age of over 500 years.
197
00:13:52,640 --> 00:13:56,080
So it takes all of Ian's35 years of experience
198
00:13:56,160 --> 00:13:58,560
to keep the locomotivesfrom breaking down.
199
00:13:59,640 --> 00:14:02,040
You're responsible
for the train that the people are in
200
00:14:02,120 --> 00:14:04,960
so you've got to understand
what you're doing,
201
00:14:05,120 --> 00:14:06,440
what can go wrong.
202
00:14:09,960 --> 00:14:11,720
NARRATOR:
It's time to board the passengers
203
00:14:12,920 --> 00:14:17,360
and stoke the furnacewhich sits inside the train's boiler.
204
00:14:18,720 --> 00:14:22,840
The hot furnace turns the watersurrounding it into high pressure steam.
205
00:14:24,480 --> 00:14:29,120
A pipe at the top of the boilerthen diverts the steam to twin pistons
206
00:14:29,640 --> 00:14:31,960
which sit either side of the front wheels.
207
00:14:35,240 --> 00:14:39,080
As the pistons fill with steam,they drive the wheels forward.
208
00:14:54,280 --> 00:14:57,240
This line includesa half-kilometer long tunnel
209
00:14:58,160 --> 00:15:00,800
and the magnificent Hooks Hill viaduct,
210
00:15:01,400 --> 00:15:04,520
designed by world renownedBritish industrial engineer,
211
00:15:04,960 --> 00:15:06,680
Isambard Kingdom Brunel.
212
00:15:08,880 --> 00:15:11,760
Finally, Kingswear.
213
00:15:13,720 --> 00:15:16,600
A picturesque fishing villagecrammed with boats.
214
00:15:21,680 --> 00:15:25,120
The steam train has completeda full run with no problems
215
00:15:26,000 --> 00:15:29,400
and all its vintage partshave made it in one piece.
216
00:15:30,440 --> 00:15:32,560
For Ian, that's a triumph.
217
00:15:33,480 --> 00:15:36,520
Hopefully, I've done a good job
and I can go and have a cup of tea.
218
00:15:36,600 --> 00:15:38,440
(laughs)
219
00:15:40,040 --> 00:15:43,280
NARRATOR: It's testament to Ianand his team's care and attention
220
00:15:43,800 --> 00:15:47,680
that this little part of British heritageis being kept alive
221
00:15:47,760 --> 00:15:49,880
for future generations to enjoy.
222
00:15:52,840 --> 00:15:56,720
As well as carving a railway networkinto the nation's countryside,
223
00:15:57,160 --> 00:16:01,800
Britain's pioneering industrial engineersbuilt another transport legacy
224
00:16:01,880 --> 00:16:03,280
that lives on today.
225
00:16:07,960 --> 00:16:12,080
In July, the midsummer heatspreads across the UK.
226
00:16:12,480 --> 00:16:14,320
From the south coast of England
227
00:16:14,880 --> 00:16:19,200
to the United Kingdom'smost northern country, Scotland.
228
00:16:20,880 --> 00:16:23,440
Here, hikers take to the highlands
229
00:16:23,520 --> 00:16:26,480
to explore some ofthe UK's tallest mountains
230
00:16:27,960 --> 00:16:31,120
as the summer thawmelts away the snowy peaks.
231
00:16:32,640 --> 00:16:36,080
In Scotland's south,the vibrant cities of Glasgow
232
00:16:36,800 --> 00:16:39,040
and the country's capital, Edinburgh,
233
00:16:39,120 --> 00:16:43,800
throng with tourists there to soak upthe art and culture on offer.
234
00:16:46,480 --> 00:16:49,040
Those that want to escapethe hustle and bustle
235
00:16:49,800 --> 00:16:53,360
take to the canalsfor a tranquil weekend on the water.
236
00:16:55,760 --> 00:16:58,400
The whole of the United Kingdomis crisscrossed
237
00:16:58,480 --> 00:17:02,000
with more than 3,000 kilometersof man-made waterways.
238
00:17:03,080 --> 00:17:06,920
Engineers built these canalsin the 18th and 19th century
239
00:17:07,000 --> 00:17:09,320
to power the industrial revolution.
240
00:17:10,000 --> 00:17:11,880
Today, they're used for pleasure.
241
00:17:14,240 --> 00:17:18,960
Scotland has two major canalsthat run between Glasgow and Edinburgh.
242
00:17:19,960 --> 00:17:23,120
They meet in the middle,at a town called Falkirk.
243
00:17:24,640 --> 00:17:27,640
From above, the two canalsappear to join as one.
244
00:17:30,880 --> 00:17:33,360
But a closer look reveals a problem.
245
00:17:34,360 --> 00:17:39,280
The undulating Scottish landscape meansthat there is a 35-meter vertical drop
246
00:17:39,440 --> 00:17:40,880
between the two canals.
247
00:17:42,080 --> 00:17:44,760
So how do you travelbetween two waterways
248
00:17:44,840 --> 00:17:46,560
on completely different levels?
249
00:17:48,360 --> 00:17:51,920
Inventive engineersdevise an ingenious solution.
250
00:17:53,480 --> 00:17:56,200
The world's only rotating boat lift,
251
00:17:57,280 --> 00:17:58,960
the Falkirk Wheel.
252
00:18:01,840 --> 00:18:04,760
Before this machine was opened in 2002,
253
00:18:05,160 --> 00:18:08,200
it would take weary boatersa day's heavy work
254
00:18:08,280 --> 00:18:10,200
to travel between the two canals,
255
00:18:10,960 --> 00:18:14,600
opening and closing44 lock gates along the way.
256
00:18:16,200 --> 00:18:21,360
Today, the Falkirk Wheel can transportbarges up and down between the canals
257
00:18:21,800 --> 00:18:23,720
in just four and a half minutes.
258
00:18:26,320 --> 00:18:29,760
Peter Robinson is the head engineerfor Scottish Canals.
259
00:18:30,920 --> 00:18:33,360
It's Peter's jobto ensure the smooth running
260
00:18:33,520 --> 00:18:37,480
of this £17.5 million engineering marvel.
261
00:18:38,640 --> 00:18:39,720
For me to be responsible
262
00:18:39,800 --> 00:18:41,680
for trying to look after it
is just superb.
263
00:18:41,760 --> 00:18:43,640
I think some days,
I've got the best job in the world.
264
00:18:45,520 --> 00:18:48,880
NARRATOR: Today, Peter and his colleagueshave seven hours
265
00:18:48,960 --> 00:18:51,800
to coordinate the movement of 25 boats
266
00:18:51,880 --> 00:18:53,880
up and down between the two canals.
267
00:18:56,560 --> 00:18:57,880
At each end of the waterway,
268
00:18:58,320 --> 00:19:00,760
the first boats of the daystart to arrive.
269
00:19:05,080 --> 00:19:08,760
The skippers steer their bargesinto water tight gondolas
270
00:19:08,840 --> 00:19:10,240
at each end of the wheel.
271
00:19:14,200 --> 00:19:16,360
Peter's colleagues in the operation room
272
00:19:16,880 --> 00:19:18,760
close the hydraulic gates
273
00:19:20,400 --> 00:19:22,040
and set the wheel turning.
274
00:19:26,320 --> 00:19:30,960
Ten hydraulic motors work togetherto power an enormous gear
275
00:19:31,040 --> 00:19:32,960
that turns the central axle.
276
00:19:33,920 --> 00:19:37,560
This raises one of the 300-ton gondolasinto the air
277
00:19:37,880 --> 00:19:39,480
while lowering the other.
278
00:19:40,560 --> 00:19:44,720
As the wheel rotates,each of the gondolas remains upright
279
00:19:44,800 --> 00:19:47,440
thanks to a simple series of giant cogs.
280
00:19:48,760 --> 00:19:50,880
ROBINSON: It's just phenomenalthe number of people that are coming along
281
00:19:50,960 --> 00:19:53,480
and reliably we just bring them through.
282
00:19:53,560 --> 00:19:55,480
It's just engineering at its best.
283
00:19:57,040 --> 00:20:01,040
NARRATOR: In each turn, the engineonly uses the same amount of energy
284
00:20:01,120 --> 00:20:02,960
as eight boiling kettles.
285
00:20:04,360 --> 00:20:06,320
For the wheel to run this efficiently
286
00:20:06,800 --> 00:20:11,520
the weight of the two gondolasneeds to be exactly the same at all times.
287
00:20:13,560 --> 00:20:16,000
But luckily that's not as hardas it sounds,
288
00:20:16,400 --> 00:20:18,440
thanks to a handy quirk of physics.
289
00:20:20,560 --> 00:20:22,720
When a boat enters either gondola,
290
00:20:23,080 --> 00:20:26,320
it displaces its own weightin water exactly.
291
00:20:29,520 --> 00:20:33,440
This means the two ends of the liftremain in perfect balance
292
00:20:34,080 --> 00:20:36,960
whether they're empty or full of boats.
293
00:20:38,640 --> 00:20:40,440
ROBINSON: It's complex yet simple.
294
00:20:40,520 --> 00:20:42,120
Whatever goes in displaces water
295
00:20:42,200 --> 00:20:45,680
and therefore the two gondolason the wheel remain balanced.
296
00:20:45,760 --> 00:20:50,320
It's absolutely brilliant to thinkabout the engineering ingenuity.
297
00:20:53,520 --> 00:20:56,200
NARRATOR: The Falkirk Wheel's designers
298
00:20:56,280 --> 00:20:59,360
created a one of a kindengineering masterpiece
299
00:20:59,680 --> 00:21:03,640
to solve a unique problemwith originality and style.
300
00:21:10,360 --> 00:21:13,600
As narrow boats make their waythrough the Scottish countryside,
301
00:21:14,480 --> 00:21:18,960
in the nearby fields malt barley farmersprepare their crops for harvest.
302
00:21:20,600 --> 00:21:24,840
This barley will go on to formone of Scotland's proudest creations.
303
00:21:29,520 --> 00:21:31,200
In Scotland's northeast,
304
00:21:33,280 --> 00:21:35,960
aerial camerasreveal countless little factories.
305
00:21:37,600 --> 00:21:38,600
What are they?
306
00:21:40,200 --> 00:21:44,000
A clue lies alongone of the nation's longest waterways.
307
00:21:44,560 --> 00:21:46,440
The mighty River Spey.
308
00:21:47,520 --> 00:21:51,000
This river has more of these factorieshidden in its bends
309
00:21:51,320 --> 00:21:53,040
than anywhere else in Scotland.
310
00:21:56,520 --> 00:21:59,960
These are Speyside'sfamous whiskey distilleries.
311
00:22:01,480 --> 00:22:05,040
They use the region's pure spring watersto make scotch.
312
00:22:07,160 --> 00:22:11,800
All this industry has given riseto a extraordinary aerial spectacle.
313
00:22:14,040 --> 00:22:18,800
A yard that stands like a Mayan templein the heart of whiskey country.
314
00:22:23,440 --> 00:22:26,680
This is the Speyside Cooperage.
315
00:22:29,040 --> 00:22:33,720
It's home to around 150,000empty whiskey barrels.
316
00:22:35,560 --> 00:22:39,120
Stacked into pyramidsalmost ten meters high.
317
00:22:42,640 --> 00:22:44,720
When the distilleries need more casks
318
00:22:45,320 --> 00:22:48,960
it's up to cooper, John Richard,to build and repair them.
319
00:22:49,760 --> 00:22:53,960
There's nothing quite like the pyramids
that we have here at Speyside Cooperage.
320
00:22:54,040 --> 00:22:58,600
A lot of people say they resemble
the ancient Egyptian pyramids.
321
00:23:00,240 --> 00:23:03,280
NARRATOR:
Scotch begins life as a colorless liquid.
322
00:23:03,440 --> 00:23:06,560
Oak barrels give it its famous golden hue.
323
00:23:07,760 --> 00:23:09,760
And once those barrels are empty,
324
00:23:09,840 --> 00:23:14,200
the distilleries send them hereto be stored and eventually refurbished.
325
00:23:17,480 --> 00:23:19,600
Today, one of the local distilleries
326
00:23:19,680 --> 00:23:23,360
has placed an orderfor 300 newly refurbished barrels.
327
00:23:27,440 --> 00:23:29,640
All the casks are repaired to order
328
00:23:30,080 --> 00:23:33,600
so they can be ready for shipmentto the distillery that very same day.
329
00:23:37,880 --> 00:23:42,520
It's time for John to get to workon a 2,000-year-old tradition.
330
00:23:48,560 --> 00:23:53,520
Inside the Cooperage, John sets to workon the order with lightning speed.
331
00:23:54,520 --> 00:23:57,200
He checks the oak staves for imperfections
332
00:23:58,200 --> 00:24:02,720
and throws any rotten wood away,replacing it with a fresh strip.
333
00:24:02,800 --> 00:24:06,480
RICHARD: We'll check for any defectssuch as broken staves,
334
00:24:06,560 --> 00:24:09,200
rusty hoops, buckled ends.
335
00:24:09,640 --> 00:24:12,240
Experience tells us what to look for.
336
00:24:12,560 --> 00:24:16,320
NARRATOR: Once the barrels have been fixedand both ends have been removed,
337
00:24:16,840 --> 00:24:20,520
the coopers do somethingthat at first glance seems crazy.
338
00:24:21,600 --> 00:24:24,840
They set each caskalight with a flame thrower.
339
00:24:25,880 --> 00:24:29,200
The coopers place the casksover a hole in the floor
340
00:24:29,920 --> 00:24:33,560
which fires out a 430 degree flame,
341
00:24:33,640 --> 00:24:36,840
blasting the inside of the barrelfor up to four minutes.
342
00:24:38,720 --> 00:24:40,480
This is called charring,
343
00:24:41,800 --> 00:24:45,640
and it holds the secretto the malt whiskey's delicate flavor.
344
00:24:46,520 --> 00:24:49,360
RICHARD: The charring caramelizesthe natural sugars
345
00:24:49,440 --> 00:24:50,960
that exist within the wood
346
00:24:51,040 --> 00:24:55,400
and this allows the alcoholto pick up flavors of honey and caramel.
347
00:24:59,200 --> 00:25:00,640
NARRATOR: In a single day,
348
00:25:00,760 --> 00:25:03,600
John and the team complete 300 barrels
349
00:25:04,240 --> 00:25:06,480
ready to be shipped out to the distillery.
350
00:25:07,880 --> 00:25:10,040
Each barrel will spend the next decade
351
00:25:10,120 --> 00:25:14,800
slowly turning a colorless spiritinto an exclusive Scottish product.
352
00:25:15,680 --> 00:25:18,760
RICHARD: Speyside is the malt whiskeycapital of the world.
353
00:25:19,600 --> 00:25:24,480
At the end of the day, when I rollmy last cask out on to the lorry,
354
00:25:24,920 --> 00:25:27,360
it's great to knowthat I have contributed something
355
00:25:27,440 --> 00:25:29,440
that is so vital to the area.
356
00:25:36,440 --> 00:25:38,200
NARRATOR: As summer draws to a close,
357
00:25:38,840 --> 00:25:42,120
the temperature across the United Kingdomstarts to cool.
358
00:25:44,400 --> 00:25:47,440
It's Novemberand the days are getting shorter.
359
00:25:49,320 --> 00:25:52,200
The morning sun paints the sky a soft pink
360
00:25:52,920 --> 00:25:55,840
and a thick mistsettles over the landscape.
361
00:25:58,080 --> 00:25:59,120
It's autumn,
362
00:25:59,640 --> 00:26:02,520
and in the north of Englanda chill in the air
363
00:26:02,880 --> 00:26:06,360
signals the start of one of the mostdramatic feats in farming
364
00:26:07,680 --> 00:26:09,920
that heralds the coming of new life.
365
00:26:15,040 --> 00:26:16,680
In England's northwest,
366
00:26:17,200 --> 00:26:20,840
in the heart of Cumbria,sits the lake district.
367
00:26:21,320 --> 00:26:23,440
A vast craggy national park
368
00:26:24,000 --> 00:26:27,440
sculpted by glaciersover the last two million years.
369
00:26:29,480 --> 00:26:34,320
Looking closer, it's a patchworkof seemingly barren mountains.
370
00:26:39,320 --> 00:26:44,880
An aerial view revealsthat this rugged landscape is farmland.
371
00:26:49,520 --> 00:26:54,360
Farmer, David Harrison,looks after 1,100 mountain dwelling sheep.
372
00:26:55,800 --> 00:26:58,120
It's a farming practice in this area
373
00:26:58,200 --> 00:27:00,600
thought to stretch back to Viking times.
374
00:27:01,520 --> 00:27:04,240
HARRISON: In the people round hereit's bred in them. It's in the blood.
375
00:27:04,960 --> 00:27:08,760
Me family's been farming here
for well over 100 years.
376
00:27:09,720 --> 00:27:12,440
I'm about the fourth, fifth generation.
377
00:27:18,920 --> 00:27:20,800
NARRATOR: David needs to bring his sheep
378
00:27:20,880 --> 00:27:22,640
back to the homestead for breeding.
379
00:27:24,160 --> 00:27:26,320
His problem is finding them.
380
00:27:30,640 --> 00:27:32,400
The sheep live semi-wild.
381
00:27:34,200 --> 00:27:37,280
Spread out across 3,000 mountainous acres.
382
00:27:42,040 --> 00:27:45,800
David's solution is to startat the top of the mountain
383
00:27:46,560 --> 00:27:47,880
with his team of dogs
384
00:27:49,000 --> 00:27:50,480
and work his way down.
385
00:27:51,960 --> 00:27:53,520
HARRISON:
I've done it that many times.
386
00:27:53,600 --> 00:27:55,560
You know the felllike the back of your hand.
387
00:27:57,120 --> 00:27:58,600
I know where my sheep are.
388
00:28:02,440 --> 00:28:05,400
NARRATOR: The further Davidand his dogs move down the mountain,
389
00:28:05,720 --> 00:28:07,600
the larger the flock becomes,
390
00:28:09,000 --> 00:28:11,720
as he picks up more and more sheepalong the way.
391
00:28:15,320 --> 00:28:18,320
HARRISON: It's gonna take usabout four to five hours
392
00:28:18,400 --> 00:28:20,800
to get all the sheep backin off that fell.
393
00:28:22,800 --> 00:28:27,560
Lose a bit of sweat on the wayand sore feet, but we'll get it done.
394
00:28:31,360 --> 00:28:33,600
NARRATOR: By the timethey reach the lowlands,
395
00:28:33,680 --> 00:28:35,520
the giant flock is complete.
396
00:28:38,160 --> 00:28:40,880
From above, it's an incredible sight.
397
00:28:42,360 --> 00:28:45,400
A thousand sheepsqueeze through the narrow gate,
398
00:28:46,600 --> 00:28:48,600
herded by David's dogs
399
00:28:48,680 --> 00:28:50,640
like sand through an hour glass.
400
00:28:56,960 --> 00:28:57,880
HARRISON: Dogs are marvelous.
401
00:28:57,960 --> 00:29:01,800
I can put a dog up to a mile awayfrom where I'm stood
402
00:29:01,880 --> 00:29:06,120
to bring sheep back to me or send themin the right direction where I want to go.
403
00:29:08,080 --> 00:29:09,200
They're invaluable.
404
00:29:09,280 --> 00:29:10,560
You couldn't do it without them.
405
00:29:17,480 --> 00:29:19,640
NARRATOR: A shepherdtaking around 100 sheep
406
00:29:19,720 --> 00:29:23,360
from one field to the nextonly needs a single sheepdog.
407
00:29:24,640 --> 00:29:27,720
When you're collecting1,000 sheep from a mountain,
408
00:29:27,880 --> 00:29:31,120
the flock is so spread out,you need more than ten.
409
00:29:33,360 --> 00:29:36,680
HARRISON: When one splits off,you have a good eye dog that'll fetch it,
410
00:29:36,760 --> 00:29:38,000
guide it back into the flock
411
00:29:38,080 --> 00:29:40,480
and you just stand stilland let the dog do its work.
412
00:29:45,560 --> 00:29:47,360
NARRATOR: It takes themtill early afternoon
413
00:29:47,440 --> 00:29:50,320
for David and his teamto finally herd all the sheep
414
00:29:50,400 --> 00:29:51,880
into the pen for breeding.
415
00:29:53,200 --> 00:29:56,280
HARRISON: The gather thatwe've just done was absolutely fantastic.
416
00:29:56,360 --> 00:29:59,680
It was their best gatherwe've had on that fell this year.
417
00:30:00,200 --> 00:30:01,680
It was just brilliant.
418
00:30:03,520 --> 00:30:05,080
NARRATOR: In just a few months,
419
00:30:05,160 --> 00:30:08,440
David's flock will give birthto the next generation.
420
00:30:10,360 --> 00:30:11,320
HARRISON: I love being on the fell.
421
00:30:11,400 --> 00:30:13,680
Gathering the fell's me favorite job.
422
00:30:13,760 --> 00:30:17,000
You can't beat itbeing out on your own with your dogs.
423
00:30:18,920 --> 00:30:22,720
I don't think I'm, eh,
cut out to do any other job.
424
00:30:22,800 --> 00:30:25,840
Um, I'm unemployable I think. (laughs)
425
00:30:25,920 --> 00:30:27,320
I'll have to stay doing this.
426
00:30:34,920 --> 00:30:38,600
NARRATOR: As autumn's damp wet weathertakes hold across the UK,
427
00:30:39,040 --> 00:30:41,840
people dream of jetting offto warmer climes.
428
00:30:42,520 --> 00:30:45,680
A cutting edge engineering workshopin the middle of England
429
00:30:46,120 --> 00:30:48,520
makes those dreams a reality.
430
00:30:53,800 --> 00:30:58,000
The Midlands are historicallythe industrial heartland of England.
431
00:30:58,640 --> 00:31:02,760
Birmingham, Coventry,and Derby were key cities
432
00:31:02,840 --> 00:31:04,480
in the industrial revolution.
433
00:31:05,600 --> 00:31:09,200
Even today, the area around Derbystill houses
434
00:31:09,280 --> 00:31:13,760
some of the most advanced transportmanufacturing workshops in existence.
435
00:31:16,520 --> 00:31:20,760
This colossal concrete structureis the Rolls-Royce test facility.
436
00:31:22,040 --> 00:31:26,320
It's here that every jet engineproduced in the neighboring assemble line
437
00:31:26,400 --> 00:31:28,440
is certified fit for service.
438
00:31:31,040 --> 00:31:33,520
Chris Pattinson is the man in charge.
439
00:31:35,160 --> 00:31:38,520
It's his job to make sureour planes can fly safely.
440
00:31:40,280 --> 00:31:42,880
PATTINSON: If we didn't havethe ability to test engines, quite simply,
441
00:31:43,240 --> 00:31:45,040
you and I couldn't go on holiday.
442
00:31:45,840 --> 00:31:48,320
This is a facility that runs
24 hours a day.
443
00:31:48,680 --> 00:31:52,680
It runs almost seven days a week
and it runs almost 365 days a year.
444
00:31:54,600 --> 00:31:57,080
NARRATOR:
Each multi-million-pound jet engine
445
00:31:57,160 --> 00:31:59,600
consists of 30,000 components,
446
00:32:00,040 --> 00:32:02,480
but as our airborne journey reveals,
447
00:32:02,800 --> 00:32:06,480
the building itselfis a modern engineering wonder.
448
00:32:08,200 --> 00:32:12,320
One room in particular is vitalfor keeping the four billion passengers
449
00:32:12,480 --> 00:32:14,920
who travel by air each year, safe.
450
00:32:17,600 --> 00:32:20,280
This is the Rolls-Royce test bed.
451
00:32:21,440 --> 00:32:24,760
PATTINSON: I remember my first time hereand what got me was the scale.
452
00:32:25,560 --> 00:32:27,640
What we do here is absolutely exceptional.
453
00:32:28,640 --> 00:32:30,400
NARRATOR: Here, Chris and his team
454
00:32:30,480 --> 00:32:34,720
fire up the 50,000 horsepower jet enginesto full throttle.
455
00:32:36,840 --> 00:32:40,240
They do this for every enginethe company builds in the UK.
456
00:32:41,280 --> 00:32:44,840
The only way to truly understandhow remarkable this room is,
457
00:32:45,920 --> 00:32:48,920
is to see it from the skyabove the building.
458
00:32:51,560 --> 00:32:54,520
A colossal fan in the toweron the right of the building
459
00:32:55,120 --> 00:32:58,760
sucks in 1.3 tons of air per second.
460
00:32:59,560 --> 00:33:04,120
The air passes through the engineat almost 1,600 kilometers per hour
461
00:33:05,280 --> 00:33:09,400
before being expelled from the buildingthrough an enormous chimney on the left.
462
00:33:11,200 --> 00:33:14,720
This super-sized vent systemmeans that Rolls-Royce
463
00:33:14,800 --> 00:33:17,800
can rigorously testevery jet engine it builds
464
00:33:18,400 --> 00:33:21,280
under the extreme conditionsthe jet could face
465
00:33:21,360 --> 00:33:23,520
at 10,000 meters altitude,
466
00:33:24,640 --> 00:33:26,920
without ever needing to leave the factory.
467
00:33:29,640 --> 00:33:31,480
The team start the engine.
468
00:33:32,560 --> 00:33:36,600
They want to replicate the effectof flying through an enormous rainstorm
469
00:33:37,240 --> 00:33:40,880
to see if the enginecan withstand over ten liters of water
470
00:33:40,960 --> 00:33:43,000
spraying through every second.
471
00:33:44,120 --> 00:33:46,360
The forces involved are huge.
472
00:33:46,960 --> 00:33:51,560
Each engine produces more thrustthan 68 Formula One cars.
473
00:33:56,160 --> 00:33:57,440
The test is over.
474
00:33:57,880 --> 00:34:00,040
The team carefully inspects the engine
475
00:34:00,120 --> 00:34:03,160
to see how it copedwith the extreme forces
476
00:34:04,200 --> 00:34:06,400
and it's passed with flying colors.
477
00:34:07,080 --> 00:34:09,360
PATTINSON: The technologythat we deal with is exceptional.
478
00:34:10,720 --> 00:34:12,320
The facilities are exceptional.
479
00:34:13,520 --> 00:34:15,680
I absolutely love it
and I wouldn't do anything else.
480
00:34:20,120 --> 00:34:22,200
NARRATOR: As autumn in the Midlands fades,
481
00:34:24,240 --> 00:34:26,840
a cold chill descends upon the UK
482
00:34:27,720 --> 00:34:31,320
and a dusting of frostcovers all corners of the nation.
483
00:34:34,680 --> 00:34:38,800
It's December and winterhas arrived in the British Isles.
484
00:34:41,200 --> 00:34:44,640
Icy coastal windsbring freezing temperatures.
485
00:34:46,920 --> 00:34:49,080
But in the heartof the Cornish countryside,
486
00:34:50,120 --> 00:34:52,600
groundbreaking British designershave found a way
487
00:34:52,680 --> 00:34:54,440
to defeat the winter blues
488
00:34:55,560 --> 00:34:59,480
by engineering a tropical climateall year round.
489
00:35:04,280 --> 00:35:06,360
On England's southern-most tip,
490
00:35:06,800 --> 00:35:09,840
nestled in amongst the ruggedCornish coastline,
491
00:35:11,240 --> 00:35:15,160
is the last place on Earth you wouldexpect to find a tropical paradise,
492
00:35:15,800 --> 00:35:17,200
but zoom in closer,
493
00:35:17,960 --> 00:35:22,200
an aerial view reveals a buildingstraight out of science fiction.
494
00:35:26,000 --> 00:35:28,680
This is the Eden Project.
495
00:35:30,400 --> 00:35:33,320
The world's biggest indoor rainforest.
496
00:35:35,400 --> 00:35:38,040
This incredible engineering masterpiece
497
00:35:38,120 --> 00:35:41,440
is a series of eight interlockingtransparent domes
498
00:35:41,760 --> 00:35:43,800
etched into the Cornish countryside.
499
00:35:49,920 --> 00:35:55,880
It's 7:00 a.m. and for daredevil gardener,David Paul, it's time to get to work.
500
00:35:55,960 --> 00:35:59,240
This is the biggest captivity
rainforest in the world.
501
00:35:59,920 --> 00:36:02,240
It's such an exciting opportunityto be able to work
502
00:36:02,320 --> 00:36:04,600
with these different treesthat you'd never be able to work with.
503
00:36:06,080 --> 00:36:08,960
NARRATOR:
Designers created the Eden Project
504
00:36:09,040 --> 00:36:13,480
to house and celebrate plant speciesfrom rainforests across the globe.
505
00:36:14,680 --> 00:36:17,800
It's home to nearlytwo million different plants
506
00:36:18,200 --> 00:36:21,200
that span threeof the world's climate zones.
507
00:36:22,160 --> 00:36:25,800
A specially designed irrigation systemcaptures rainfall
508
00:36:26,160 --> 00:36:28,760
which is recycled to water the plants,
509
00:36:29,080 --> 00:36:30,880
feed the ten-meter waterfall
510
00:36:31,240 --> 00:36:33,080
and add to the dome's humidity.
511
00:36:35,520 --> 00:36:36,760
But there's a problem.
512
00:36:38,440 --> 00:36:40,480
The tropical conditions are so good
513
00:36:40,880 --> 00:36:42,520
the plants inside the domes
514
00:36:42,600 --> 00:36:45,160
grow just as fast as they wouldin the wild.
515
00:36:46,600 --> 00:36:50,280
If left unchecked,this could cause a serious issue.
516
00:36:51,160 --> 00:36:53,560
The trees could penetrate the dome itself
517
00:36:53,680 --> 00:36:55,200
and then once
that is open to the elements,
518
00:36:55,360 --> 00:36:57,520
all the other trees would potentially die.
519
00:37:03,800 --> 00:37:07,120
NARRATOR: The Eden Project's canopyis growing so quickly
520
00:37:07,200 --> 00:37:09,920
it's close to bursting throughthe greenhouse roof.
521
00:37:11,040 --> 00:37:12,280
If that were to happen,
522
00:37:12,680 --> 00:37:15,320
all the speciesthat this habitat protects
523
00:37:15,400 --> 00:37:16,480
would be at risk.
524
00:37:18,560 --> 00:37:21,680
Today, David and the teamhave just three hours
525
00:37:21,760 --> 00:37:24,880
to trim the branchesbefore the morning rush of visitors.
526
00:37:27,240 --> 00:37:30,160
The rope crew haul their wayto the top of the structure.
527
00:37:32,200 --> 00:37:35,560
It's the dome's geodesic designthat holds the secret
528
00:37:35,640 --> 00:37:38,240
to the Eden Project's phenomenal success.
529
00:37:41,480 --> 00:37:45,560
More than 800 different plastic sheetsmake up the structure.
530
00:37:46,920 --> 00:37:50,120
An ultra light steel frameholds them together
531
00:37:51,040 --> 00:37:53,440
to create the perfectly rounded domes.
532
00:37:56,920 --> 00:38:01,040
This giant bubble wrapped shelllets in as much light as possible,
533
00:38:03,800 --> 00:38:05,760
while insulating the rainforest
534
00:38:06,600 --> 00:38:10,760
to between 18 and 38 degrees Celsiusall year round.
535
00:38:12,640 --> 00:38:15,520
Working in these temperaturestakes some skill.
536
00:38:16,960 --> 00:38:19,280
Especially when maneuvering a chainsaw.
537
00:38:22,480 --> 00:38:24,720
PAUL: It is challengingworking in here in the heat.
538
00:38:25,120 --> 00:38:27,880
The metal work can get so hot in herethat you can cook an egg on it.
539
00:38:30,320 --> 00:38:31,280
-(man yells indistinctly)
-Okay.
540
00:38:31,360 --> 00:38:32,480
Okay. Below!
541
00:38:35,200 --> 00:38:37,240
NARRATOR: The rope teamtrim the branches
542
00:38:37,320 --> 00:38:39,320
and glide back down to ground level.
543
00:38:40,440 --> 00:38:41,880
It's a job well done.
544
00:38:45,520 --> 00:38:49,160
Over a million peoplevisit the Eden Project each year
545
00:38:49,240 --> 00:38:51,800
to marvel at its botanical wonders
546
00:38:51,880 --> 00:38:55,080
as well as the incredible structurethat houses them.
547
00:39:01,000 --> 00:39:03,280
At the opposite end of the United Kingdom,
548
00:39:04,000 --> 00:39:07,320
the January weatherpaints Scotland white with snow.
549
00:39:09,160 --> 00:39:10,800
In the east of the country,
550
00:39:10,880 --> 00:39:13,680
Scottish engineers have usedthe natural landscape
551
00:39:14,280 --> 00:39:16,000
to create a surprising home
552
00:39:16,760 --> 00:39:18,880
for some of the biggest machines on Earth.
553
00:39:23,120 --> 00:39:28,520
Scotland's east coast is a landof narrow sea inlets called firths.
554
00:39:30,200 --> 00:39:34,120
Glaciers carved these deep baysduring the last ice age.
555
00:39:37,640 --> 00:39:39,960
Just 30 kilometers north of Inverness,
556
00:39:40,680 --> 00:39:42,160
sits Cromarty Firth.
557
00:39:45,040 --> 00:39:48,640
It appears to be dottedwith strange industrial structures.
558
00:39:50,680 --> 00:39:51,560
What are they?
559
00:39:53,720 --> 00:39:56,600
A closer look revealsthe surprising truth.
560
00:39:57,760 --> 00:40:01,920
This is an enormous repair yardfor oil rigs.
561
00:40:03,800 --> 00:40:07,200
The North Sea is filledwith over 600 of these giants
562
00:40:08,240 --> 00:40:10,240
but when the rigs need repairs,
563
00:40:10,320 --> 00:40:13,280
they're towed hereto the shelter of the firth.
564
00:40:16,000 --> 00:40:18,560
Calum Slater is in charge of the port.
565
00:40:20,280 --> 00:40:22,000
It's his job to make sure
566
00:40:22,080 --> 00:40:25,280
these rigs are hauled throughCromarty Firth's waterways
567
00:40:25,680 --> 00:40:27,720
to the waiting engineering companies
568
00:40:27,800 --> 00:40:29,920
without running aground on the rocks.
569
00:40:31,040 --> 00:40:32,080
Every job that we do,
570
00:40:32,600 --> 00:40:35,480
we carry the responsibility
for this stretch of water.
571
00:40:35,560 --> 00:40:38,200
We always want to be surethings are going to plan.
572
00:40:41,920 --> 00:40:43,400
NARRATOR: Calum's task today
573
00:40:43,760 --> 00:40:48,040
is to move an enormous oil rigfrom the mouth of the firth into dock.
574
00:40:50,600 --> 00:40:54,200
The monster machineis worth around £40 million.
575
00:40:56,720 --> 00:40:59,160
To tow the massive oil rig into harbor,
576
00:40:59,840 --> 00:41:04,000
Calum doesn't just use one giant tug,he uses two.
577
00:41:06,360 --> 00:41:10,600
Rigs float thanks to giant buoyancy aidscalled pontoons
578
00:41:11,200 --> 00:41:14,040
which lie just below the water's surface.
579
00:41:16,640 --> 00:41:18,000
But when they're being moved,
580
00:41:18,440 --> 00:41:23,080
these same pontoons drag in the water,making the rigs less stable.
581
00:41:24,640 --> 00:41:27,240
So while one ship pulls the rig forwards,
582
00:41:28,040 --> 00:41:32,600
the other tugs in the opposite directionto help keep the rig upright.
583
00:41:34,240 --> 00:41:38,360
Each towing vesselhas a 28,000 horsepower engine
584
00:41:39,240 --> 00:41:41,960
and is almost as longas the Statue of Liberty.
585
00:41:46,360 --> 00:41:48,920
SLATER: Rig moves can takeanywhere between eight
586
00:41:49,000 --> 00:41:52,200
to 17, 18, 19 hours in--in duration.
587
00:41:53,840 --> 00:41:56,840
NARRATOR: Progress is painfully slow.
588
00:41:57,680 --> 00:41:59,840
The rig barely seems to move.
589
00:42:01,680 --> 00:42:02,880
But over the next hour,
590
00:42:02,960 --> 00:42:05,440
the rig creeps forward nine kilometers
591
00:42:05,760 --> 00:42:07,480
to reach its final goal,
592
00:42:08,680 --> 00:42:11,640
the docking siteat the port in Invergordon.
593
00:42:17,360 --> 00:42:18,960
The rig is 90 meters long
594
00:42:19,320 --> 00:42:21,320
and 76 meters wide.
595
00:42:23,400 --> 00:42:25,880
But it needs to squeeze into this space
596
00:42:26,560 --> 00:42:28,920
less than 150 meters across.
597
00:42:31,360 --> 00:42:34,800
The space is too narrowfor the colossal towing vessels
598
00:42:34,880 --> 00:42:36,600
that brought the rig into the firth.
599
00:42:38,760 --> 00:42:42,680
So smaller more maneuverableharbor tug boats take over.
600
00:42:49,240 --> 00:42:53,040
Meter by meter, the tug boatscarefully tow the rig
601
00:42:53,520 --> 00:42:54,760
into the docking site
602
00:42:59,520 --> 00:43:03,680
and align it with the side of the jettyso the rig is parallel.
603
00:43:09,280 --> 00:43:10,320
It's dusk
604
00:43:10,800 --> 00:43:13,760
and the team havesuccessfully landed the rig in the dock.
605
00:43:14,640 --> 00:43:18,920
The crew on board have made it homein time for a well-earned break.
606
00:43:19,360 --> 00:43:23,000
SLATER: At the end of the day,we're glad that it's done safely.
607
00:43:24,160 --> 00:43:26,120
NARRATOR: The port's engineering companies
608
00:43:26,200 --> 00:43:29,840
will spend the next few monthsgiving the rig a full service.
609
00:43:30,480 --> 00:43:31,760
When they're finished,
610
00:43:31,840 --> 00:43:35,800
this colossal machinewill head back out to the North Sea
611
00:43:35,880 --> 00:43:38,400
in search ofblack gold once more.
612
00:43:42,360 --> 00:43:44,600
The UK is an island nation
613
00:43:45,400 --> 00:43:47,800
with a thirst for engineering innovation
614
00:43:49,160 --> 00:43:52,040
that has left a permanent markon the world's stage.
615
00:43:53,560 --> 00:43:57,480
It has a rich cultural historythat spans many different regions.
616
00:43:59,240 --> 00:44:02,920
They all retain their own unique stampof individuality
617
00:44:03,760 --> 00:44:07,600
but come together as one united kingdom.
