Stability Analysis & Hydrostatics

Complete stability engineering from hydrostatics and intact stability through probabilistic damage stability, progressive flooding analysis, and trim optimisation for ships, offshore units, and passenger vessels.

What We Offer

3 specialist capability areas

01

Intact Stability

  • Hydrostatic CalculationsDisplacement, VCB, BM, KM, and curves of form across the full draft range.
  • Intact Stability AssessmentGZ curve analysis, righting energy, and compliance with IS Code 2008, HSC Code, or flag state rules.
  • Loading Manual PreparationApproved loading conditions covering departure, arrival, and required intermediate conditions.
  • Load Planning Software SupportIntegration with onboard loading computers and voyage planning tools.
02

Damaged Stability & Survivability

  • Probabilistic Damage Stability (SOLAS 2009)B/GM assessment with subdivision index R and attained index A calculation.
  • Deterministic Damage StabilityZone flooding cases for ferry, passenger vessel, and naval applications.
  • Progressive Flooding AnalysisTime-domain flooding simulation for watertight subdivision adequacy.
  • Residual Stability (Offshore)Damage case assessment for semi-submersibles, FPSOs, and jack-ups.
03

Trim & Longitudinal Strength

  • Trim OptimisationLoading condition optimisation to minimise resistance through trim and draft management.
  • Bending Moment & Shear Force CurvesStill-water and wave-induced hull girder loading envelopes.
  • Freeboard CalculationLoad line assignment in accordance with the International Load Line Convention.
