Project Number 422
Date of Summary October 19, 2004
Subject Earthquake Assessment of Subsea Facilities/GOM
Performing Activity Texas A&M University, Offshore Technology Research Center (OTRC)
Principal Investigator Bracci and Hueste
Contracting Agency Minerals Management Service
Completion December 2003
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:
  1. Review historical seismic activity and seismic risks in the GOM;
  2. Identify prototype sub-sea structural and non-structural systems;
  3. Develop representative structural models and analysis procedures;
  4. Identify performance limits states, and
  5. 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.
Progress This project has been completed and final report has been accepted.
