Computational tool for information management and integrity assessment of subsea rigid pipelines

Resumo

Subsea rigid pipelines, widely used to transport fluids in oil and gas production activities, require an
Integrity Management System to ensure that there are no economic, environmental, material nor human losses
throughout their design life. In this work, an overview of methodologies for data management and generation of
results for integrity assessment will be presented. Then, such methodologies are implemented into an integrated
specialist software that is currently under development. The aim is to obtain a robust and efficient computational
tool whose application in real scenarios will provide the following benefits: a) Productivity gains during the
processes of evaluating the integrity of submarine rigid pipelines, including the centralization of relevant
information from the history of inspections and pipeline operating conditions; b) Generation of standardized
technical reports containing results of integrity assessments under operational conditions; c) User-friendly
interface to access information on the operational history of the pipelines during its design life; d) Assistance in
the integrity management of subsea rigid pipeline systems, according to the normative and regulatory
requirements; e) Ease in analysis sensitivity of relevant parameters, since it integrates, within the same
computational system, resources for data acquisition, information processing and integrated assessments of
different engineering analyses.
