Learning Objectives

Upon successful completion of this course, participants will be able to:

1. Fundamentals of Offshore Structural Engineering

  • Understand the principles of offshore structural design and analysis.
  • Identify types of offshore structures:
    • Fixed platforms (jackets, gravity-based structures).
    • Floating structures (FPSO, semi-submersibles, TLPs).
    • Subsea structures (pipelines, risers, templates).
  • Learn international design codes and standards (API RP 2A, ISO 19902, DNV-GL, ABS).

2. Introduction to Structural Analysis for Offshore Platforms

  • Understand load types and their impact on offshore structures:
    • Environmental loads (waves, currents, wind, earthquake, ice).
    • Functional loads (equipment weight, live loads, operational forces).
    • Accidental loads (collision, explosion, dropped objects).
  • Perform static, dynamic, and fatigue analysis for offshore structures.

3. Overview of SACS Software and Its Applications

  • Understand SACS capabilities in offshore structural analysis.
  • Learn about SACS modules:
    • Precede (Modeling Interface).
    • Structural Analysis (Linear and Nonlinear).

6. Fatigue and Reliability Analysis in Offshore Structures

  • Understand fatigue life prediction and stress concentration factors (SCFs).
  • Perform fatigue analysis based on spectral and deterministic approaches.
  • Ensure compliance with offshore fatigue design standards.

7. Post-Processing, Reporting, and Optimization

  • Interpret analysis results using graphical and tabular outputs.
  • Generate detailed reports for structural integrity assessment.
