Geanti has the capability the following types of subsea analyses:
Pipelines (risers/flowlines) and subsea cables installation using Orcaflex.
Subsea structures installations such as PLET/PLEM.
FE analysis for Subsea Pipelines’ and Jumpers’ VIV using direct Fluid-Structure Interactions (FSI) and coupled Soil-Structure interactions.
Flow forces inside/outside the pipe, deflections/ stresses/vibrations, Inflow and Cross flow responses and Fatigue Life calculations due to VIV.
Jumper VIV fatigue analysis using DNV FatFree when the current direction has conservatively been presumed to be perpendicular to the M-shaped jumper span. The natural frequencies and unit diameter stresses for the VIV analysis are calculated using ABAQUS. Stress Concentration Factors (SCF) are calculated based on API Spec 5L with the weld misalignment value obtained from API 1104 also included in the SCF calculations
