3. WHAT IS TRANSATLANTIC???
• Theoretical high speed tunnel
spanning Atlantic between Newyork
and London.
• Reaches destination in just 54 min.

4. PATH
13 September 2015 4
Route depends on :
FACTORS
SAFETY
COST
Earlier proposed path
passes through
Canada,Greenland ,Iceland
and Norway.
Practical path 3100 mile
undersea.
Canada
Greenland
Norway
Iceland

5. TIMELINE
13 September 2015 5
1895
Jules .Verne suggested idea
1888
Ernst .G. Frankel proposed
idea
1935
Film named “Trans -atlantic”
released
1972 Harry. Harison wrote science
fiction

6. FACILITIES PROVIDED
TRACKS
EASTWARD WESTWARD AUXILLIARY

7. Power and communication
• Power provided by generators to
substations in tunnel
• Service tube provides power and
communication
13 September 2015 7

8. Safety
• Massive GPS monitors tunnel
as well as its entire cables
• For any shift in seafloor
automated system get works
by retensioning of cables
• Sensors watch problems and
computers would be in
disaster mode

9. Change in speed
Passenger discomfort
caused
Solutions
a) Use pivoting
/rotating seats
b) Airlock

faced by tunnel engineer
• Massive suppression

12. Have a look on how it would be built???
13 September 2015 12

13. METHODS OF CONSTRUCTION
A)IMMERSION TUNNEL
1) Tunnel section
 Tunnel sections would be made in
Holland factories
 Concrete is poured and made to set
 Each 300 foot long section consumes
30,000 tonnes of steel and concrete
 54,000 sections needed for trans -
atlantic

14. Cont…
2) Moved to sea
 Each section
sealed tight with
steel buckells at
each end
 Dry dock flooded
and massive tubes
towed to sea
13 September 2015 14

15. Contd…
3)Keep in position
 Immersion pontoon carry
each section directly
above its position in
underwater
 It is partially flooded
cause it to sink
 Divers place sections in
right place
13 September 2015 15

16. Contd…
4)Join different sections
 Lining done on each joint
 Huge rubber gaskets used
Above method was used
in construction of BART
13 September 2015 16

17. B)SUBMERGED FLOATING TUNNEL
 Transatlantic would be seen 150 -300
m below surface
Advantages
1. Deep enough to avoid interference
2. Avoid high pressure resistance at bottom
3. Feasible
 Firstly proposed in Norway
13 September 2015 17

18. o VAC TRAIN
Forces that reduce speed
a) Friction(Maglev)
b) Airresistance(Vaglev)
 Vaglev provided by 100 jets working 24
hours for 2 weeks
 Provides 6400-8000 kmph
13 September 2015 18

19. Methods to keep tunnel in position
INSERTION OF
PIERS
SUPPORT
FROM TOP
SYSTEM IN
OIL PLANTS
13 September 2015 19

20. • INSERTION OF PIERS
Piers are inserted in rivers and streams at
regular interval
Acts as underwater bridge
Cost is thousands of dollars
13 September 2015 20

21. • SUPPORT FROM TOP
Huge” floating pontoons”
might hold tunnel in
position from top
Atlantic currents carries
100 times water a day
Home to “Gulf stream”
13 September 2015 21

22. • SYSTEM IN OIL PLANT
Uses
1. Steel pipes
2. Suction anchors
Suction of water creates vaccum
Works on principle of upside
pendulum
13 September 2015 22

23. Hindrances in
construction
• $17 billion- $12 trillionCost
• Needs steel output of world
for entire year
Material
availability
• Mid atlantic Ridge is
seismically active
• Five earthquakes per day
Geology
13 September 2015 23

24. Contd…
• Atlantic is treacherous
• Net output of
Nile,Amazon,Mississipi
Weather
• Steel cables should be strong
against harsh oceanStability
• Needs a century to complete
Time

26. CONCLUSION
 If ever built transatlantic tunnel would be massive
construction project in human history
 It is an idea for which every civil engineer must be
proud of.
 The words of Frank Davison” Trans –atlantic is
not beyond reach of modern science and
technology” reveals it can happen in near future
 The main hindrances are time and cost
