Course overview
This course covers static catenary analysis for subsea engineering systems. It develops the static analysis methods needed for pipelines, moorings, umbilicals and risers, and closes with applied problem-solving and a CALM buoy feasibility design task.
What you will learn
Classify subsea line problems by catenary assumption, current regime and governing load case.
Apply weight-only catenary equations to calculate geometry, tension and curvature limits for mooring and pipe-lay problems.
Analyse drag-only and combined-force catenaries using two-point relations and Pode’s cable-function method.
Calculate surge and heave effects at the catenary top end and use the equations sheet as a design aid.
Evaluate which static catenary method best fits a range of subsea engineering scenarios.
Scope a preliminary CALM buoy mooring and flexible-riser feasibility design from a technical brief.
