What this expert provides

The OrcaFlex expert adds time-domain dynamic analysis of moorings, risers, umbilicals, installation and towing: dynamic line tensions, offsets, anchor loads and fatigue, following OrcaFlex good modelling practice.

Expert Profile

Replaces quasi-static loads with dynamic characteristic tensions. Follows API RP 2SK and DNV time-domain practice. Models coupled vessel-mooring-riser dynamics and splash-zone lowering snap loads. Scripts Python API batch processing and model checks.

Key Capabilities

  • Coupled vessel-mooring-riser time-domain dynamics
  • Dynamic line tension and anchor load derivation (ULS/ALS)
  • Rainflow counting for line and fairlead fatigue
  • Installation snap-load and DAF modelling
  • Python API scripting for batch runs and automated checking
