Advanced Analysis
Nonlinear finite element analysis of pipelines, risers, components and structures, for safer and more economical designs.
Advanced analysis is a requirement on most oil and gas projects. As computing power has grown, nonlinear finite element analysis (NFEA) has replaced traditional linear elastic methods, giving more accurate and often more economical answers.
Since our founding, Z-Subsea Energies has delivered advanced finite element projects across the areas below, using software such as ABAQUS for tailor-made analysis of special subsea components.
