3. Palm Islands
Palm islands consist of three artificial islands –
 Palm Jumeirah (completed)
 Palm Jebel Ali (under construction)
 Palm Deira (proposed)

4. About Palm Jumeirah
 Palm Jumeirah is located on the
coast of Dubai, United Arab
Emirates.
 It is developed from the theme of
Dubai’s national tree Palm.
 It consists of a tree trunk, a crown
with 16 fronds, and a surrounding
crescent island that forms an
11 kilometer-long breakwater.

5. CONSTRUCTION
 Construction on the palm islands
began in June 2001.
 Sand dredged from the bottom of
the Persian Gulf by the Belgian
company Jan De Nul and the
Dutch company Van Oord.
 Divers surveyed the seabed and
workers constructed a crescent-
shaped breakwater from blasted
mountain rock.
 The sand is sprayed from dredging
ships, guided by a (DGPS) to plot
the palm and ensure the sand
placement within 0.39 of an inch.

6. CONSTRUCTION
 The spraying process is known
as rainbowing.
 3.25 billion cubic feet of ocean sand vibro-
compacted into place.
 The Crescent of Palm Jumeirah stands a little
more than 13 feet above low tide sea level.
 Sand, covered by an erosion-preventing
water-permeable geo-textile.
 One-ton rocks cover the sand, and two
layers of large rocks weighing up to six tons
each cap the structure.
 The breakwater also has two 328-feet
openings on each side to eliminate stagnation
in the 16 narrow deep channels.

Using rocks

7. Construction resources involved
 5.5 million cubic meters of
rock brought from over 16
quarries in Dubai.
 210 million cubic metres of
rock,sand and limestone.
 94 million cubic meters
of sand brought from
deep sea beds 6 nautical
miles from the coast of
Dubai.

8. Area covered by Palm Jumeirah
 The island itself is 5.72 km².
 It adds a total of
520 kilometers of non-
public beaches to the city of
Dubai.
 It adds 78 kilometers to the
Dubai coastline.
 The island costs an
estimated $12bn to build.

9. Structural importance
 Palm Jumeirah was
built entirely from
sand and rocks which
is a wonder of
modern engineering.
 Recover the revenue
of oil and make a
tourist attraction.

10. Residential units & Hotels
 The developers handover
the first residential units in
2006.
 In October 2007, the Palm
Jumeirah had already
become the world's largest
artificial island.
 By the end of 2009, 28
hotels were opened on the
Crescent.

11. Project risks and threats
 Waves 2 meters high.
 Storm frequency of 1
in 1 year.
 Earthquakes from 6
to 7 on the Richter
scale.
 Weak soil
 Water pollution.

12. Hidden problems
 Erosion(caused
by winds and
water currents).
 Damage to the
marine ecology
(the loss of reefs
and fish)
 Loss of coastal
shape along the
seashore of Dubai.
Erosion
Damage to the marine ecology

13. Obstacles after the island construction
 Installation of utilities and pipelines were very difficult and
laborious.

14. Risk Mitigation
 Wave blockers.
 Dredging (the sand from the
dredging ships was sprayed on
to the land).
 GPS.
 Monitored and checked the
proper alignment and placement
of rocks to maintain the
construction.
 Anti Liquefaction process
(Vibro-compaction technique)
Wave blockers
Dredging

15. Environmental concerns
 Changes to area wildlife, coastal erosion,
alongshore sediment transport and wave
patterns.
 Suffocated and injured local marine fauna
and reduced the amount of sunlight which
filters down to seashore vegetation.
 Change in erosion patterns along the UAE
coast.
 For these reasons, Greenpeace
and Mongabay has criticized the Palm
Islands for lack of sustainability.
