mooringDesignSimulator v2: a tool for mooring design and simulation

Detailed introduction to mooringDesignSimulator v2, its use cases, and its current software structure.

13 May 2026

mooringDesignSimulator v2 is a desktop application focused on the design and static simulation of oceanographic moorings.

The goal is not only to draw a mooring line. The software also helps organize components, prepare a project, run a simulation, review the results, and produce a usable PDF report.

Why revisit this tool now

Several tools developed over the years deserved to be updated so they remain usable, documented, and easier to transmit. mooringDesignSimulator v2 is one of them.

Recent work has strengthened the application around a more durable base:

  • a clearer application entry point
  • real SQLite project persistence
  • a more readable graphical design workspace
  • a more explicit simulation pipeline
  • better structured PDF reporting
  • a test suite that covers sensitive areas

What the application can do

The software currently allows users to:

  • load a component library
  • build a mooring graphically
  • edit segment properties
  • save and reload a project
  • run a static simulation
  • display result tables and charts
  • generate a PDF report

Main interface

A clearer architecture

The repository documentation describes an architecture organized around four main subsystems:

  • a PySide6 graphical interface
  • SQLite-based project persistence
  • component library management
  • a simulation pipeline made of an adapter, a preprocessor, a solver, and an output layer

That separation matters because it makes the tool easier to maintain and evolve.

Data formats and workflow

The main working format is a SQLite database, usually stored as *.mooring.sqlite3. The application can also import and export JSON snapshots, but the core workflow now relies on a stronger and more structured persistence layer.

On the simulation side, the project follows a straightforward pipeline:

  1. read the project
  2. adapt it into simulation models
  3. preprocess the data
  4. run the static solver
  5. return results to the UI and the PDF report

Public documentation

Public documentation is now progressively republished on this website:

Who it is for

This software is relevant for people who work on the design, verification, or documentation of oceanographic moorings and need a visual, reproducible, and maintainable tool.
