Abstract: Over the years, new discovers and associated technical challenges have spawned
significant research and development efforts in a broad range of areas, in order to
improve efficiency and reliability, and also to keep the risks associated with the new
scenarios in an accepted range. Some aspect that can be mentioned include, for
instance, improvements in line grade steels and innovations in the manufacture of
tubular products; development of several pipeline installation methods and lay-vessels;
establishment of the mechanical behavior and the expected modes of failure of long
tubes and pipes under various loads; investigation of new problems in fluid-structure
and soil-structure interactions, issues of corrosion, welding, fatigue, integrity
management philosophy, and many others.
Many of the problems mentioned have been brought about by the demands of the new
frontiers, where the operating conditions and the environmental parameters may lead to
the introduction of new risks and situations not fully covered in established standards
and design codes.
Therefore, the objective of this work is to present and discuss the unique design needs
and challenges related to the offshore pipelines to be designed and installed on the
Brazilian Pre-Salt fields. The paper presents and discusses, for instance, aspects related
to materials, design criteria, installation issues, and an approach for the evaluation and
qualification of new technologies.
