One of the major attractions of this cruise was the Panama Canal. We were
looking forward to the transit through the canal and it was great! It's very
special to sail through a narrow canal that's man-made and to go through
several of the largest locks in the world! With the maps and photos below we
hope you get a bit of an impression of how we experienced the Panama Canal.
The
Panama Canal connects the Pacific Ocean to the
Atlantic Ocean (Caribbean Sea). The canal sort
of cuts America in half: South America below the
canal, the rest above.
The canal goes
from Panama City to Colón.
Here
you see a detailed map of the Panama Canal. The
colored dots mark the most important
places.
Very
early in the morning (around 5.30am) we sailed
into the Panama Canal, under the 'Bridge of the
Americas', with a view on Panama City. At
6.00am, we were at the first set of locks, the
Miraflores Locks. Everyone on the ship got up
early today…
We're
approaching the Miraflores Locks. Another ship,
the container ship Majestic Maersk just enters
the lock. We are supposed to sail into the lock
on the left hand side. Two ships can be locked
through at the same time, sailing in the same
direction or in the opposite direction.
It's
very crowded on every front deck. This is
something you must see. Luckily the ship is
large enough to give everyone a good
view.
The
first locomotive is already waiting for us to
assist and tow us through the locks.
Depending
on the ship's size, from 4 to 8 locomotives are
assisting and towing a ship through the locks.
Using strong steel cables, they keep the ship in
position and prevent it from hitting the walls.
The ship is also using its own engines for
propulsion.
Now
we're in the first part of the Miraflores Locks.
The Majestic Maersk is next to us in the
parallel lock-chamber.
The
Control House of the Miraflores Locks, on the
center wall of its higher chamber, from which
the entire operation is directed. Every set of
locks has its own Control House.
Now
we've raised 8 metres (about 25 feet). The
Control House is much more on our level now. We
are ready for the second lock chamber.
The
rack-railway for electric locomotives. Notice
there is only very little space left between the
ship and the lock chamber wall. Ships are
designed and built to be able to pass through
the Panama Canal.
We've
passed the Miraflores locks with its two lock
chambers that raised the ship 17 metres. Only a
little distance away the second locks are there:
the Pedro Miguel locks, with only one
lock-chamber that raises us another 8
metres.
This is
a graphic cross-section of the Panama Canal with
its three sets of locks.
Here's
a cross-section of one set of locks, like the
Gatun locks. The water is pumped from the lake
into the first lock chamber to raise the water
level, and is released into the next lock
chamber to lower the water level in the first
one and raise the level in the second one.
Ultimately the 197 million (!) liters of fresh
water are flushed into the sea.
The two
parallel lock chambers are also connected to
each other. The water from one lock-chamber can
be used for the other.
It's
still very crowded on the upper deck. And it's
getting hot and humid. We're ready to enter the
Pedro Miguel locks.
A
picture taken from the rear of the ship. We're
in the Pedro Miguel locks now. Another container
ship is ready to enter the parallel lock
chamber. On the background you see the
Miraflores locks.
Notice
the double doors. If one breaks down, for
example when a ship hits it, not much harm is
done. The water is still blocked by the second
door. This is a safety measure to prevent a
disaster.
We have
left the Pedro Miguel locks, now approaching the
most narrow part of the Panama Canal and the
Centennial Bridge
The
Centennial Bridge (Puente
Centenario).
Did you know that a full
priority passage for a cruise ship like the
Legend of the Seas costs about $150,000? So now
you know why cruises that transit the Panama
Canal are a bit more expensive than other
cruises.
The
bridge has a total span of 1,052 metres. The
bridge is 80 metres high. The two towers are 184
metres high. It's a brand new bridge, completed
in 2004. See for more information and photos here.
The
smallest part of the Panama Canal: the Gaillard
Cut. Very impressive to be sailing with such a
large ship in such a narrow passage.
The
Gaillard Cut is an excavated channel about eight
miles long. It requires regular maintenance to
maintain depth and width to permit passing
ships. Here you see the leftovers of a rock that
was blasted to pieces making room for the
canal.
In the
smallest parts of the Panama Canal, our ship is
being assisted by a tug-boat.
The
nature at the sides of the Panama Canal is very
green and dense. It's a warm and humid climate
here.
You can see the railway that also
goes from Panama City to Colón and that follows
the Panama Canal route mostly.
There's
a continuous dredging program going on keep the
Panama Canal deep enough. This is one of the
dredges at work. The Panama Canal Authority
(ACP) is constantly preparing, updating and
executing long-term plans and programs for a
variety of maintenance and improvement
projects.
This is
one of the ships we passed by and this one has
an odd shape. Now we've left the narrow part of
the canal and are on the Gatun Lake.
In the
distance you can see the Gatun Dam, nearby the
Gatun Locks. This dam prevents from flowing all
the water from the lake and the canal into the
Atlantic Ocean. There are a few more dams around
the Panama Canal, like the Madden Dam and the
Chagres Dam, which also help to maintain the
level of the water at 85 feet above sea level.
The Madden Dam also has an hydroelectric power
plant.
Here,
on Gatun Lake where we anchored, people on
tugboats are trying to free one of the ships
anchors from a piece of wood. This wood is
blocking the anchor from being pulled up
completely. Finally they succeeded, but we had a
delay of almost two hours.
We're
at the Gatun Locks. Boatmen on small rowing
boats receive lines from the transiting vessels
when they enter the locks. The lines are
connected to the electrical locomotives so they
can help towing the ship. Can anyone tell me why
they use rowing boats for this purpose that
don't even have simple engines? We haven't
figured that out yet.
The
cables are being connected to the
locomotives.
Slowly
we proceed through the Gatun Locks. A complete
passage through the Panama Canal and all the
lakes usually takes less than 24 hours for
normal traffic and 7 to 8 hours for priority
traffic such as passenger vessels, like our
cruise ship. It took us more than 12 hours
because we anchored in Gatun Lake (people were
getting off the ship to do some excursions) and
we had some additional delay because of the
piece of wood in our anchor.
It
still fits! There's less than two feet of space
left. All of the lock chambers of the canal are
1000 feet long, 110 feet wide with a minimum
depth of 41 feet.
In the
lock chamber parallel to us lies an oil tanker.
No smoking please…
Here
you can see the container ship leaving the last
lock chamber, so the water is at sea level
there. The prior lock chamber has it's water
level to the high position. So the difference
between the two water levels is two times 28
feet = 56 feet (around 17 metres).
A
closeup of one of the doors or gates. Here you
can see the difference in water levels
well.
We're
in the last lock chamber. They open some hatches
and all the water from this chamber is flowing
to the lower side, so our water level is
dropping until it's been leveled out. This
happens with some force, as you can see
here.
We
have left the Gatun Locks and are at sea level
again. Now you've got a good view on the Gatun
locks and the differences in water
levels.
There
are some webcams aimed at the Miraflores Locks,
the Centennial Bridge and the Gatun Locks. On
the Internet you can see live images from ships
passing these locations. This is one of the
webcams. You can have a look yourself at this site.
At the
Port of Cristobal, near Colón, we are docked and
are able to do some shopping and get the chance
to buy some 'Panama Canal' souvenirs. It's the
end of an interesting day. Transiting the Panama
Canal is very special.
Everyone
on the ship received this certificate as proof
for transiting the Panama Canal.
