Lifting of Heavy Loads and Construction Stages - América do Norte, Central e Sul, Brazil
Introduction
The team of Odebrecht Industrial Plants is responsible
for internal consulting and technical support on
engineering solutions for all Odebrecht’s contracts.
The main effort is to analyse the different stages of
the assembling of huge equipment through designing
specific accesses or a group of accessories that allow
the required movements, which means the manipulation
of heavy loads until the end of the installation process.
These accessories and/or accesses are normally not
considered during the conception of the equipment
design, but are fundamental to their installation.
About our work
The workflow is based on simple client information
regarding the equipment, and the first decision is to
define the machines (the cranes) that will make the
movement. Subsequently, the equipment itself is
analysed in order to check if it supports the lifting loads in
the different construction stages. The analysis will define
if reinforcement is necessary for the installation process
or even for the equipment operation. The accessories
are defined based on global and local analyses of the
introduction of loads. Scia results define the material and
components, with the information flowing to the customer
and the internal Odebrecht S.A. team.
The analysis is based on American Standard Code
AISC 89, but in some cases, for a refined analysis,
Eurocode is used.
Use of Scia Engineer
Scia Engineer has been used since 2011. The biggest
discovered benefit was the shells study. The tools used
previously did not allow easy modeling with a refined
analysis that considered heavy loads manipulation.
The projects are distributed across different parts of
the world, including Brazil, Mexico, Houston, Argentina
and Italy. The main challenge in these contracts is
the deadline, which demands an agile analysis, a
quick dialogue with the support team, and fast and
reliable results, since maintenance stops for important
equipment are involved.
In citing some main examples of the use of
Scia Engineer, we refer to some projects where
advancements in the field of analysis and accurate
calculation were possible. The Scia Engineer response
is very close to the real structure behaviour.
In conclusion, the use of Scia Engineer means, for us,
Practicality for Consulting Engineering through a user
friendly interface and large gains in modelling.
