Integrity management and life assessment is very demanding in all industrial applications and, in high deep subsea, to keep the structural integrity of all components safe is critical. Failure is a process that has time on its side and, if catalyzed by aggressive media, temperature, and pressure, leads to many possible combinations of damage mechanisms.

One can easily visualize the corrosion in metals or degradation in polymers, which may result in crack nucleation and its subcritical growth. Fatigue is also part of the life reduction process, associated or not with environmental effects. The damage process is not constant in time, but changes as the well reservoir is depleted and with the action of the environment itself. For instance, the presence of high quantities of CO2in Santos Basin (pre-salt) and its effecton structural integrity and corresponding life assessment demands a great deal of studies (for the past-used pieces of equipment and future ones – such as TCP). Failure can happen in localized parts, not necessarily leading to the whole component malfunction, but it will shorten its operation life. The failure process begins at the namo or microscale, a locus of metallurgical and materials engineering expertise, where small-scale samples are tested and evaluated; and then moves to structural macroscale analysis, where medium/large scale tests and analysis/modeling are conducted, the locus of mechanical, civil, or naval engineering. To skill a metallurgical/materials engineering to understand global structure behavior is as important as to skill a mechanical/civil/naval engineering with microscale behavior in a major/minor academic formation. To tackle this demand in Brazil's oil & gas sector, the Brazilian Petroleum Agency (ANP) established a human resource program to support the Integrity Management & Life Assessment in subsea operations and renewable energies, named PRH 7.1.

This paper will report on the PRH 7.1 academic structure to supply human resources for the oil & gas sector, focused on Integrity Management & Life Assessment. It will also show three examples of ongoing research in the program: Case 1: Design and construction of a permeation cell and the measurement of CO2 permeation in PVDF; Case 2: Theoretical and finite element analysis of a laminated composite pipe under combined axisymmetric loading; and Case 3: Study of nonlinear structural behavior during the operation of installation of subsea equipment.
