Corrosion-induced metal loss reduces the burst capacity of ageing offshore pipelines, yet its effect on pipelines in African offshore fields remains poorly quantified. This study presents a nonlinear finite element analysis (FEA) of an API 5L X70 steel pipeline (outside diameter 600 mm, wall thickness 30 mm) containing...

Offshore subsea pipelines in the Gulf of Guinea are subjected to the combined effects of deepwater hydrostatic pressure, soft-clay seabed conditions and a high-intensity metocean environment. In this paper, an integrated analytical-numerical approach is developed for evaluating the stress and on-bottom stability of one...

The shipping industry faces increasing pressure to reduce greenhouse gas emissions while maintaining operational efficiency. This study evaluates the energy-saving potential of an Organic Rankine Cycle (ORC) system for waste heat recovery from a 21,840 kW MAN 8S65ME-C8.6 main marine diesel engine during a realistic 1,6...

The Gulf of Guinea, a critical hub for global offshore hydrocarbon production, presents unique challenges for subsea pipeline integrity due to its complex environmental conditions, including deep waters, soft seabed soils, and dynamic metocean forces. This research conducts a comprehensive stress and stability analysis...

Offshore pipelines are critical infrastructure for hydrocarbon transportation from subsea production facilities to processing systems. However, seabed irregularities and hydrodynamic forces often lead to unsupported free spans that threaten pipeline structural integrity through excessive bending stresses and vortex-ind...
