Course overview
Relevance to CPD: Refreshes the static catenary methods engineers use to check pipelines, moorings, umbilicals and risers before relying on commercial analysis software.
1. Classify subsea line problems by catenary assumption, current regime and governing load case.
Designed for: engineering graduates looking for refresher courses in niche expert areas.
Entry requirements: an engineering degree or equivalent experience, plus basic solid mechanics, statics and elementary fluid mechanics; familiarity with subsea or offshore line systems is helpful but not required.
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.
