Resumo: | ||||||||
The reduction of pipeline wall thickness caused by corrosion
is one of the
defects that more affect pipeline structural integrity.
These defects can take place
in the metal base, in the longitudinal and circumferential
welding. With the
expansion of the rigid submarine pipelines mesh already
installed and considering
the advanced time of using, the oil industry has been
developing several tools for
pipeline repair without compromising the safety and avoiding
production stops.
The preliminary objective of this work was the study and the
generation of
computer models, which once parameter, they could be a tool
for analyze the
repair connection of submarine pipeline. During this study,
about two types of
repair connection, it was realized that the behaviour at
failure described by the
connection numerical models has details which needed to be
explained in addition
to the considered experimental program (Alves). One phase of
this research was
the laboratory works in which it was possible to repeat the
mixture of epoxi resin
and cement, according to the references adopted in the
experimental program
(Alves). Compression test were conducted on cylindrical
specimens made of this
mixture for determining the stress-strain curve and the
Poisson coefficient.
Another phase of this research was the consulting of other
works which could
indicate the expected behaviour of the mixture subjected to
the compression load.
Finally, analytical and numerical models of repair
connection were generated the
results were compared with those obtained on experimental
program (Alves)
Based on comparison, discrepancies were detected as well as
they possible causes.
Suggestions to obtain the initial objective were indicated.
