of a Marina resort in Limassol.
The Limassol Marina is an integrated
project including unique residential
island properties.
The luxurious Marina combines the
yachting facilities with residential and
commercial development with
beautiful Mediterranean views for an
exclusive lifestyle.
The Marina Lemesou Joint Venture
between the companies J&P, Cybarco
and Athena has been awarded a
contract for development of the new
Limassol Marina in the south of
Cyprus Island. The main breakwater
which protects the marina is covered
by a revetment
made of ACCROPODE units.

After a study performed in in
Wallingford, the ACCROPODE unit
was selected for its intrinsic robustness
and its capacity to resist to the highest
waves conditions, for the construction
of the new revetment.
Before and during the construction,
special advises were given by CLI for
the toe design that is essential for the
stability of the whole armouring.
The CLI commitment consisted in
providing both, technological solution
and a specific technical support to the
Contractor by sending a specialist on

Background
The project is located at the North east
of Qatar, in the RAS LAFFAN Industrial
city. The project consisted in the
construction of two new breakwaters
for the LNG PORT breakwaters in order
to shelter the future LNG facilities.
These breakwaters are protected with
artificial armour units such as cubes
and ACCROPODE units. The
ACCROPODE technology was selected
to be placed at the most exposed areas
of the two structures (north and south
breakwaters).
The ACCROPODE placing had to be
carried out in a very tight schedule.
Several positioning systems were used
in order to save time and increase the
placing rate:
• POSIBLOC system
• ECHOSCOPE sonar
• Video cameras
Hydraulic excavators were also used in
order to increase the placing rate.
All of the units were fabricated in
Ajman (U.A.E) and shipped over during
the construction.

Background
The Commune di Imperia has decided to
extend the port of Oneglia by lengthening
the main breakwater of 160m and creating
a secondary breakwater next to a new
quay. These operations targeted to
increase the length of quays available and
decrease the agitation in the port. In order
to carry out this project, one company was
awarded for each of the two breakwaters.
The Idresia company was in charge of the
main breakwater and the SET company
was in charge of the secondary
breakwater. Both of the structures were
covered by ACCROPODE units. The main
breakwater was protected by 3m3 and
4m3 ACCROPODE units. The fabrication
yard was located a few kilometres away
from the breakwaters. The units were
placed by land by using a crane and
excavators.

Background
In the framework of the MOSE
project, aimed at protecting
Venice from high tides, a series of
works have been carried out in
the lagoon and its three inlets. The
specific purpose of these works is
to create mobile barriers at each
inlet that will close off the lagoon
during high tides. Since these
barriers are unable to withstand
very large waves, the lagoon inlets
had to be protected with offshore
breakwaters.
The Malamocco entrance
channel is the closest one to
Venice and is also a point of
access to the Mestre crude oil
terminal.
Services provided by Sogreah
Throughout the works, Sogreah
provided technical assistance to
the contractor.
This involved supplying the
technical information required
in order to implement the
ACCROPODE technique
correctly and to train the placing
teams. Placing drawings were
drawn up in close collaboration
with the Contractor, in order to
take account of the equipment
being used and the anticipated
placing schedule.
A Sogreah expert visited the site
several times in order to ensure
that the ACCROPODE technique
had been implemented correctly
and to improve the placing rate
and quality.

container traffic in Hong Kong
itself, and at the same time
reduce traffic on the roads and
mitigate environmental impacts.
The project involved the
construction of a 65 ha landfill
platform offering 3000 linear
metres of berthing facilities.
The landfill is protected against
cyclonic waves by two
breakwaters, one of which is
built offshore. The breakwaters
themselves are protected by a
facing of 2.5 et 3 m 3
ACCROPODE ® blocks.
Design criteria
The breakwaters were sized to
withstand the following design
waves:
◆ Return period: 100 years
◆ H s = 4.2 m
◆ T p = 7 sec

Protection of the sheet-pile
structure forming the ferry loading
platform at the western end of
the jetty was also included in the
project.
The jetty was consolidated with
a facing of 2.5 and 4 m 3
ACCROPODE ® artificial blocks.
