Asset Management Improved Reliability Models for USACE Navigation Structures

PI: Yazmin Seda-Sanabria (GSL)

Problem:Need for improved reliability models to predict

actual field performance of Corps navigation infrastructure and assist in future investment planning of critical maintenance.

  • Currently used mechanical and electrical equipment models are based on annual failure rates, not specific to navigation structures.
  • Geotechnical models currently used yield inconsistent results on expected operational performance.

Improved Reliability Models for USACE Navigation Structures

Products:

  • Time-dependent (capacity vs. demand) reliability models for electrical and mechanical operating components.
  • Base geotechnical time-dependent reliability models.

Benefits:

  • Significant cost savings on critical maintenance (including major rehabilitation) of Corps navigation infrastructure.
    • Improved engineering tools that can be integrated into economic models to make risk-based sound investment decisions.
