| Description |
Project
to assess the vulnerability, operability, and safety of sub-sea production
systems in the GOM during earthquakes of varying probabilistic seismic
intensities. The assessment involved participation from industry and
regulatory representatives to define current sub-sea systems, technologies,
operation, concerns, and the potential mitigation actions during times of
events (earthquakes). Research Tasks have been broken out into these areas:
- Review historical seismic activity and
seismic risks in the GOM;
- Identify prototype sub-sea structural and
non-structural systems;
- Develop representative structural models
and analysis procedures;
- Identify performance limits states, and
- Conduct a performance based probabilistic
evaluation of representative sub-sea systems and identify potential
failure mechanisms during earthquakes.
Waiting on finalized papers and distribution
and analysis and evaluations. |
