- Trim, stability booklet & loading manual; weight & CoG control
- Resistance, powering & CFD — Holtrop-Mennen, ITTC, OpenFOAM / ANSYS Fluent
- Seakeeping & operability — RAOs, motion criteria
- Global performance analysis (GPA) — FPSO / FLNG motions & air-gap
- Mooring & station-keeping — spread / turret (OCIMF MEG4, DNV-OS-E301), coupled OrcaFlex, fatigue
- DP capability & footprint — IMCA M 166, DNV-ST-0111
- Offloading & multi-body interaction — tandem & SBS
Marine Operations & Installation
- Loadout — SPMT & skidded, ballast / grounding
- Offshore transportation — barge motions & accelerations
- Towing & flotation — self-floating stability, buoyancy control
- Jacket launch & upending — trajectory, deballasting, controlled flooding
- Float-over installation — mating, ballast sequence, LMU / DSU
- Pipelay installation — S-lay / J-lay (OrcaFlex)
