PATH
Iceland
Greenland
Norway
  • Route depends on

Canada
  • Earlier proposed path passes through
    Canada,Greenland ,Iceland and Norway.
  • Practical path 3100 mile undersea.

5
TIMELINE
1895
Jules .Verne suggested idea
1888
Ernst .G. Frankel proposed idea
1935
Film named Trans -atlantic released
Harry. Harison wrote science fiction
1972
6
FACILITIES PROVIDED
7
  • Power and communication
  • Power provided by generators to substations in
    tunnel
  • Service tube provides power and communication

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
  • Use pivoting /rotating seats
  • Airlock

10
Fire
  • Most concerned problem faced by tunnel engineer
  • Massive suppression systems installed

11
MATERIALS OF TRANSATLANTIC
Steel
12
Have a look on how it would be built???
13
METHODS OF CONSTRUCTION
  • A)IMMERSION TUNNEL
  • 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

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

16
Contd
  • 4)Join different sections
  • Lining done on each joint
  • Huge rubber gaskets used
  • Above method was used
  • in construction of BART

17
  • B)SUBMERGED FLOATING TUNNEL
  • Transatlantic would be seen 150 -300
  • m below surface
  • Advantages
  • Deep enough to avoid interference
  • Avoid high pressure resistance at bottom
  • Feasible
  • Firstly proposed in Norway

18
  • VAC TRAIN
  • Forces that reduce speed
  • Friction(Maglev)
  • Airresistance(Vaglev)
  • Vaglev provided by 100 jets working 24 hours for
    2 weeks
  • Provides 6400-8000 kmph

19
Methods to keep tunnel in position
20
  • INSERTION OF PIERS
  • Piers are inserted in rivers and streams at
    regular interval
  • Acts as underwater bridge
  • Cost is thousands of dollars

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

22
  • SYSTEM IN OIL PLANT
  • Uses
  • Steel pipes
  • Suction anchors
  • Suction of water creates vaccum
  • Works on principle of upside
  • pendulum

Hindrances in construction

Compare TAT with winners in Sea and Air
FEATURES TRANSATLANTIC CONCORD BLUERIBAND
Speed 6400-8000 kmph 2179 kmph 47.15 knots
Time 52 min 3 hours 3 days 15 hours 25 min
Passenger Capacity 100 1500
Fuel used Uses electricity Jet A-1 Energy efficient
Intial Cost 17 billion- 13 trillion 7 million 173.3 million
Accidents Paris Incident Weather,Collided with ice berg
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
