KEY PROFESSIONAL DATES AND EXPERIENCES
After his degree in Naval and Mechanical Engineering
in the University of Genova (Italy) in 1963,
Carlo Avanzini has been active in the field of land and marine pipelines,
first in the field of oil P/Ls, then transferring his interests to civil pipelines.
From the early 70s, he has designed or has intervened as engineer and supervisor
in a wide range of projects in different countries, with own Companies
or as free-lance consultant teaming with engineering companies or colleagues
He brings as references projects in steel, HDPE, GRP in diameters up to 4000 mm.

4. International engineering support is given to HAWLE /NOVA SIRIA
on the application of Steel Compression Couplings
and, in GCC, to PROCO (USA) on the DuckBill Valves
for diffusers and coastal discharges
AVANZINI MIDDLE EAST FZE – SHARJAH, U.A.E.
The cooperation on international projects
is in favor of engineering companies, material suppliers and contractors, and
includes design, preparation of specifications,
construction method statements, planning and supervision.

5. AVANZINI MIDDLE EAST FZE – SHARJAH, U.A.E.
One of the first documented project was the design and supervision of the outfall
discharging pre-treated water from a paper factory in Silifke, Turkey
Concrete Coated Steel 900mm x 900m (1985)
Numerous marine and outfall projects, easy or very engaging,
successful or better forgotten are now past history, only
reminded in old faded out papers and photos
Locations, main data and photos of a few major projects in the last [25] years
are shown in the next slides; others are collected in my CV.

6. ISTANBUL ÜSKÜDAR OUTFALL (1989)
Steel, 1219.2mm, concrete coated,
275m long to -43m depth
Launched with short ramp in 3 sections joined
by rubber flexible joints, bottom pull from the
site through a cable return deviation block
anchored on the bottom at 350m distance
ISTANBUL BALTALIMANI OUTFALL(1989)
Steel, 2 x 1727,2.2mm, 300m long to -73m depth
Twin pipes launched with short ramp in 2 sections
joined by rubber flexible joints.
Bottom pull from opposite side of Bosphorus
at 1200m distance with a cable deviation block
midway on the bottom at -75m depth.
AVANZINI MIDDLE EAST FZE – SHARJAH, U.A.E.

7. Substitution of a section of the shore approach
of the Marmara Gas Pipeline, damaged by the
underwater slippage of a clay lens.
The pressure of the landslide had buckled the pipe
upwards and caused a severe leak.
The project included the construction of the new
string, the cut and removal of the damaged length,
the bottom pull of the news string to the junction
point, lifting of the two ends for the off-barge dry-
welding of the sections .
The pipe was kept in position for welding by two
rotating clamps and supended for the alignment to
two cranes and two davits and finally
lowered in position.

Transmissions to
other islands
respectively 1450m,
1370m, 2150m
AVANZINI MIDDLE EAST FZE – SHARJAH, U.A.E.

13. The need of the substitution of the original diffuser
with a new taered one to be connected to the main
ND2500 GRP line required an intervention to be
performed with a time-limited interruption
of the plant.
The connection was studied on paper and a
combination of GRP short spools and of tailor-made
Compression Couplings, designed with 400 mm axial
tolerance and ± 3° allowable angular deflection been
realized in 8 hrs, practically without idisturbance
to the TPP operation.

MERSIN GRP DIFFUSER REPAIR (2010)
It has been interesting to see that
there have been a minimum fouling of
the internal surfaces.
Only local limpets groups vere present.
It was provided a
new section with one
port and the missing
length was
compensated with a
long, specially
designed steel
compression coupling.

SOCHI OUTFALL, RUSSIA (2012)
[FIRST STAGE]
The project was stopped after the pipe failure
The pipe was tested in Germany and resulted not meeting
the standards
Prefabrication and towing
started to raise doubts on the
pipe’s real strength, but the
first string broke after
the start of the installation
of the ballast blocks

21. Ballast blocks and saddles,
as well as the compete
installation calculations and
procedures were
completely redesigned
The installation of line and
diffuser was completed
without problems.
