Alcan Gove Third-Stage Expansion—G3 Project
An AUD$2 billion expansion of the Alcan Gove
alumina refinary on the Gove Peninsula in
Australia will increase production capacity from
two million tons to 3.8 million tons per year by
2007. Because the refinery is in a remote location, finding a skilled workforce large enough to
complete this project using traditional methods on
site would have been almost impossible.
So Alcan split the project into 600 pre-assembled
modules, each weighing up to 2000 tons. The
modules are fabricated and fitted-out off site in
five locations. A 3D Bentley Plant model was
issued to each fabrication site, where fabricators
brought the 3D models into their systems, added
details, and fabricated straight from the models.

operations. In addition, laser scanning was used
to model the existing refinery tie-in points so every
aspect of the off-site fabrication was covered.
The modules were then shipped to the site where
they were quickly and efficiently installed. The
approach enabled the engineers, fabricators, and
on-site construction workers to work in parallel.
With its innovative strategy, Alcan reduced the
expected project completion time by six months.
This could give it an extra six months of increased production capacity, or roughly 900,000
tons of alumina. ;

PLANT MANAGED ENVIRONMENT
CHP Suszec—Mine Gas Utilization Genset 4MW
There are many hard-coal mines in Silesiawith,
Poland, with rich coal deposits and methane. The
gas is a threat that needs be drained from
deposits. This is not only a question of safety, but
of ecology and economy as well. One solution is
to use the gas to generate electric power and
thermal power for the coal mine's auxiliaries.
In this project, the natural link joining several engi-
neering teams was Project Wise. Working in this
managed environment allowed EPK to avoid
many mistakes related to outdated design inputs,
since all designers were given exactly the same
data in each phase of performance. It also sped
up project handling by a GRI team collaborating
with subcontractors. ;
The scope of this project included installation of
an electric generator in the area of Spólka
Energetyczna (power company) and Jastrz´bie
SA at Elektrocieplownia (thermal power plant)
Suszec. The generator consists of a German-made TCG 2032 V16 type gas engine, an AVK-made DIG 150 M/6 type generator, and a heat
recovery system. The new electric generator was
installed in the existing boiler building in place of
a demolished coal-fired boiler WR 25.
