Pipeline Construction Projects
Hybrid
air
vehicles
could
have
a
valuable
role
in
many
construction
projects,
but
pipeline
projects
are
particularly
interesting.
The
construction
is
spread
out
over
thousands
of
miles
and
an
immense
volume
of
pipe
and
other
materials
has
to
be
transported
through
areas
with
minimal
infrastructure.
There
are
at
least
four
major
pipeline
projects
planned
for
Canada
and
the
north
as
of
December
2005.
They include:
Mackenzie Valley Pipeline (gas) - $7 billion
Alaska Pipeline (gas) - $13 billion
Gateway Pipeline (oil) - $2.5 billion
Keystone Pipeline (oil) - $2.0 billion
Logistics Challenges Relating to
Northern Pipeline Construction
Several
transportation
related
challenges
face
the
developers
of
northern
pipelines
for
which
hybrid
air
vehicle
are ideally suited:
Soft
and
sensitive
ground
conditions
limit
construction
to
a
short
winter
season
where
conditions
of
cold
and
darkness
are
at
their
harshest.
This
creates
a
massive
logistics
challenge
because
the
entire
requirements
for
pipe,
construction
material,
camps,
equipment
and
personnel
must
be
mustered
to
the
northern
sites
during
the
off-
season
so
that
everything
is
available
for
the
short
construction season
There
is
significant
stress
placed
on
the
existing
infrastructure
of
roads,
rail
and
barges.
Given
the
high
peaking
demands
of
the
construction
season,
planners
must
decide
whether
to
upgrade
existing
infrastructure
that
will
then
be
overbuilt
for
ongoing
requirements,
or
risk
congestion and the related costs.
Project
risk
and
cost
is
significantly
different
for
northern
projects
because
of
the
uncertainties
of
weather,
local
ground
conditions
and
the
distance
that
these
construction
sites
are
from
their
supply
points.
Unforeseen
upsets
can
scuttle
the
construction
schedule
thus
causing
a
delay
of
not
a
few
months
but
a
whole
year.
The
interest
costs
and
opportunity
costs
associated
with
these
types
of
catastrophic
delays compound the project risk and costs.
Redundancy
in
equipment
and
supplies
is
necessary
to
mitigate
some
of
the
project
risk.
However,
having
two
items
of
a
critical
part
or
piece
of
equipment
adds
considerably
to
the risk.
Standby
costs
are
inevitable.
It
doesn't
make
sense
to
demobilize
the
equipment
south
during
the
off-season.
However,
the
equipment
owners
must
be
given
standby
fees
to
compensate
for
the
fact
that
their
equipment
must
remain
idle for up to eight months per year.
Northern
drilling,
which
is
essential
to
justifying
the
pipeline
faces
similar
seasonality.
The
costs
of
drilling
a
single
exploration
well
in
the
north
can
be
as
high
as
$25
million.
Of
this
amount
up
to
30%
of
the
costs
relate
to
northern
operations
and
would
not
be
incurred
in
southern
drilling.
People
movement
will
also
be
a
significant
challenge.
The
Mackenzie
pipeline
is
schedule
to
be
constructed
in
two
winter
seasons.
This
will
result
in
very
large
construction
crews.
These
crews
will
be
housed
in
large
construction
camps
that
will
be
built
along
the
right-of-way.
However,
this
means
that
on
a
daily
basis
these
crews
must
be
transported
from
the
camp
to
the
construction
sites.
At
its
furthest
point
between
camps
this
will
require
a
2-hour
trip.
Again
this
adds to the costs and reduces the efficiency.
Mackenzie Valley Pipeline
The
Mackenzie
Gas
Project
proposes
to
build
a
1220-
kilometre
pipeline
system
along
the
Mackenzie
Valley.
It
would
link
northern
natural
gas
producing
wells
to
southern
markets.
The
main
Mackenzie
Valley
Pipeline
would
connect
to
an
existing
natural
gas
pipeline
system
in
northwestern
Alberta.
The
natural
gas
exploration
and
development
companies
involved
in
the
Mackenzie
Gas
Project
have
interests
in
three
discovered
natural
gas
fields
in
the
Mackenzie
Delta
-
Taglu,
Parsons
Lake
and
Niglintgak.
Together,
they
can
supply
about
800
million
cubic
feet
per
day
of
natural
gas
over
the
life
of
the
Project.
Other
companies
exploring
for
natural
gas
in
the
North
are
also
interested
in
using
the
pipeline.
In
total,
as
much
as
1.2
billion
cubic
feet
per
day
of
natural
gas
could
be
available
initially
to
move
through
the
Mackenzie
Valley
Pipeline.
Planning,
building
and
operating
the
proposed
$7
billion
Mackenzie
Gas
Project
will
take
cooperation
among
many
different
companies,
communities,
settlement
regions,
regulatory agencies and governments.
Alaska Pipeline
This
project
is
competing
with
the
Mackenzie
Valley
project
and
is
being
lead
by
the
Alaska
Gas
Producers.
The
Alaska
Highway
pipeline
would
begin
at
Prudhoe
Bay,
Alaska,
parallel
the
oil
pipeline
to
Fairbanks,
and
then
follow
the
Alaska
Highway
through
the
Yukon
and
northeast
B.C.
and
on
into
Alberta.
The
AHPP
will
carry
gas
to
southern
markets.
Approximately
760
km,
or
30%
of
the
route,
would
be
in
the
Yukon.
The
pipe
itself
would
be
42-52
inches
in
diameter.
Pipeline
capacity
would
be
2.5-5.6
billion
cubic
feet/day.
The
construction
and
operation
of
the
AHPP
is
expected
to
generate
up
to
375,000
person
years.
This
project
is
estimated
to
cost
$13
billion
to
construct
and
depends
upon
permits to drill in environmentally sensitive areas in Alaska.
Gateway Pipeline
The
Gateway
Pipeline
is
being
proposed
by
Enbridge
Inc.
and
is
envisioned
to
be
a
30-inch,
400,000
barrel
per
day
pipeline
running
from
Edmonton
to
the
west
coast
of
British
Columbia,
where
ships
would
take
crude
oil
and
petroleum
products
to
refineries
in
California
and
the
Far
East.
Pending
regulatory
approvals,
construction
could
begin
by
2008
and
it
would
be
operational
by
2009/10.
A
regulatory
application
for
the
$2.5
billion,
1,160-kilometre
(720-mile)
crude
oil
pipeline
would
have
to
be
made
in
2006
to
achieve
a
late
2009/2010
in-service
date,
which
is
when
Enbridge's
Western
Canada
crude
oil
supply
forecast
indicates
that
oil
sands
production
will
have
increased
to
the
level
that
access
to a major new market will be beneficial to producers.
Keystone Pipeline
TransCanada
Corporation
is
proposing
a
US$1.7
billion
oil
pipeline
project
to
transport
approximately
400,000
barrels
per
day
of
heavy
crude
oil
from
Alberta
to
Illinois.
Transporting
oil
from
Hardisty,
Alberta
to
markets
at
Wood
River
and
Patoka,
Illinois,
the
proposed
Keystone
Pipeline
would
be
about
3,000
kilometres
(1,870
miles)
in
length.
In
addition
to
new
pipeline
construction,
it
would
require
the
conversion
of
1,240
kilometres
(770
miles)
of
one
of
the
lines
in
TransCanada's
existing
multi-line
Alberta
and
Mainline
natural
gas
pipeline
systems
in
Alberta,
Saskatchewan
and
Manitoba.
TransCanada's
other
existing
pipelines
will
continue
to
transport
Western
Canada's
natural
gas to markets in Canada and the United States.
