Overview

Numerical simulations reveal the impact of mooring line failures on platform stability under extreme ocean conditions.

Key Points

  • The research investigates how mooring line failures affect the stability of a semi-submersible platform in severe ocean environments.
  • Conducted numerical simulations on single and double mooring line failures.
  • Examined progressive failures of multiple mooring lines.
  • Analyzed the changes in utilization factors under different environmental conditions.
  • Identified significant changes in utilization factors after mooring line failures.
  • Found that two double mooring line failures can trigger subsequent failures.
  • Observed large horizontal drift of the platform during progressive failures.
