Course overview
Relevance to CPD: Refreshes the hydraulic, flow-assurance, structural and installation checks used in subsea pipeline design.
1. Analyse single- and multiphase hydraulics for pressure loss, liquid hold-up and thermal behaviour.
Designed for: engineering graduates looking for refresher courses in niche expert areas.
Entry requirements: an engineering degree or equivalent experience, plus basic fluid mechanics (pressure, flow and friction); no prior subsea pipeline design study is assumed.
What you will learn
Analyse single-phase and multiphase pipeline hydraulics to estimate pressure loss, liquid hold-up, and thermal behaviour.
Evaluate major flow-assurance threats and select mitigation strategies for hydrates, wax, asphaltenes, emulsions, and slugging.
Apply structural pipeline design checks for wall thickness, collapse resistance, and buckling behaviour.
Assess route selection, on-bottom stability, shore approach, and trenching options for offshore pipeline systems.
Compare offshore installation, manufacturing, welding, coating, and inspection methods for marine pipelines.
Evaluate pipeline life-cycle risks and offshore safety practices for subsea engineering projects.
