Top 9 Best Ship Stability Software of 2026

DelftShip is built for stability and loading-condition work where hydrodynamic data, compartment definitions, and calculation cases must stay consistent across iterations. The workflow is oriented around assembling inputs once and re-running analyses for many draft and trim combinations, which reduces the risk of transcription drift between cases. Output focuses on stability curves and margin checks, and it also handles compartment flooding setups needed for damage scenarios.

A tradeoff appears in governance and repeatability, since teams still need careful project hygiene for input management across models and scenarios. DelftShip fits best when an organization already has ship particulars and compartment data organized per project and needs repeated intact stability and damage stability studies across many loading conditions.

NAPA is a stability analysis solution built around engineering inputs like hydrostatic tables, loading conditions, and compartment states, then producing calculation outputs tied to specified criteria and scenarios. Teams typically use it to run intact stability checks and damage stability analyses on structured sets of conditions, not one-off spreadsheets. The software’s study orientation helps engineers keep configuration locked to a revision when multiple iterations are produced for design changes. Integration depth is strongest where project teams already standardize on NAPA input generation and output consumption through repeatable exports and internal engineering processes.

A tradeoff appears for organizations that need highly customized automation, because NAPA’s strongest leverage comes from disciplined study templates rather than open-ended scripting and arbitrary data shape changes. NAPA fits usage situations where an engineer must generate consistent results for class society review packages or internal design gates across many drafts and loading states. It is less suitable for teams that expect stability computation to be fully driven by external API calls for every single scenario at runtime.

Autoship fits maritime engineering groups that already work from defined loading conditions and want repeatable stability calculations tied to those inputs. It focuses on scenario management, calculation runs, and report packaging so teams can rerun analyses after drafts, weights, or assumptions change. Its documentation output reduces manual copying of results between tools, which helps when multiple drafts and iterations must be reviewed.

A key tradeoff is that Autoship is not positioned as a general purpose stability engine for every niche workflow, so teams with highly customized calculation pipelines may need external preprocessing or manual input mapping. It works best when engineering staff need consistent handling of recurring cases, such as periodic design revisions or recurring customer loading condition sets.

GHS focuses ship stability engineering on a controlled workflow for intact stability checks, damage stability analysis, and loading condition verification. The tool supports repeated loading condition generation with hydrostatic table inputs so engineers can trace draft and trim impacts on GZ curves and margins.

GHS also handles damage scenarios through compartment flooding logic, including cross-flooding and progressive flooding sequences tied to the selected case set. Administration features align with team governance needs by keeping model configurations consistent across projects and supporting review-grade outputs from the same calculation setup.

AVEVA Marine Stability performs ship loading and stability calculations using its stability engineering workflow and calculation engines. It supports intact stability outputs such as GZ curve generation and margin checks, and it also covers damage stability analysis workflows used for approvals.

AVEVA Marine Stability integrates into AVEVA’s engineering environment so project data and loading conditions can be reused across studies. It provides automation and extensibility options for repeatable condition generation and batch stability reporting.

SHIP-STABILITY by DNV targets maritime engineering teams that need repeatable ship stability calculations tied to class society expectations. The tool supports intact and damage stability workflows, including loading condition generation and scenario management for compartment flooding studies.

It also includes result reporting for GZ curve checks and margin style outputs used during plan review and condition verification. SHIP-STABILITY is oriented around engineering data handling and calculation traceability rather than general spreadsheet modeling.

MARS by SSI targets ship stability calculation workflows with engineering-grade checks for intact and damage conditions used in class and regulator submissions. It centers on loading condition management and hydrostatic style input handling to drive GZ curve outputs, limit line evaluation, and scenario comparison across drafts and trims.

The tool also supports damage stability analysis workflows used for compartment flooding and progressive effects. Its distinct focus is generating stability results consistently from structured project data rather than running single-run worksheets.

PIAS from sarc.nl is used for ship stability work where engineers must tie multiple calculation checks to defined loading conditions and deliver consistent outputs for review.

The software includes intact stability evaluation with GZ curve generation and margin-oriented reporting, plus damage stability analysis driven by flooding and compartment scenarios.

Teams typically gain time by reusing defined calculation configurations across iterations rather than rebuilding inputs for each revised condition.

Cadmatic Hull Design generates and analyzes hull forms with modeling workflows designed for ship and offshore geometry work. It ties hull geometry to stability-relevant calculations through an integrated calculation and results workspace used for loading conditions and hydrostatic outputs.

The tool supports repeatable design iterations by reusing hull geometry and project settings across study runs. Cadmatic Hull Design is most practical when stability checks depend on consistent hull geometry inputs and traceable study outputs.
