This DOCTORATE research is to be developed in the context of RCGI’ project #34 (www.usp.br/rcgi). Underground storage is not only the safest way to stockpile hydrocarbons or toxic materials but also the most economically efficient way. Although a large number of caves are in operation in the world, there are few records of accidents involving these facilities, and most of them refer to old projects developed when little experience and regulation regarding the design, construction and operation of caves was available. However, salt caves gradually have their volume decreased due to the process known as "Salt Creep" and, for this reason, stability over time cannot be guaranteed in case of its use for CO2 recovery, when the cave is not purged for a long period – a fact that should be considered in a risk analysis.
Despite its important contribution to the design and operation of salt caves for the storage of
natural gas, the existing norms and recommendations cannot be considered sufficient for the
analysis of CO2 storage in caves of salt.
Therefore, this research project should consider the basic references applicable to the risk analysis
of offshore facilities and the standards and recommendations cited above for the development of
the analysis of the risks associated with each one of the four macro disciplines that must be
developed aiming at the viability of storage of CO2 in salt caves, namely: Well Engineering;
Engineering of storage of GN / CCS in salt caves; Underwater engineering, and; Guarantee of
outflow and engineering of process plant equipment.
This DOCTORATE position is suitable for a highly motivated candidate, with an intermediary or
advanced English knowledge. Candidates must have an undergraduate or master degree in Naval
Architecture and Ocean Engineering, Mechanical (or Industrial) Engineering, or Mechatronics
Engineering, familiar with techniques commonly applied in risk analysis of offshore utilities or
operations. It is recommended that the candidate has been accepted in the Graduate Programme
of Naval Architecture and Ocean Engineering of the University of Sao Paulo or similar, or that is
willing to join a Programme.
The selected candidate will receive a scholarship of R$ 2.784,60 (first year) and R$ 3.446,40
(2nd, 3rd and 4th year) reais monthly granted by FUSP – Foundation of Support to the University of São Paulo.
