Three tools for class-facing work.

Rule compliance, inclining experiments and onboard loading — built by practising naval architects who submit these calculations for approval themselves.

Rule compliance

ClassCode AI

A retrieval engine that reads classification society rules and returns the exact clause, the formula behind it, and the variables you need to fill — instead of you hunting through a thousand-page PDF at eleven at night.

  • Clause-level references you can cite directly in a submission
  • Formulas extracted with their symbols and units intact
  • Works across rule sets and revisions, so you can compare editions
  • Every answer carries its source — nothing is asserted without a clause

WL w d M G GM θ Pendulum stays vertical · the batten reads the deflection tan θ = deflection / pendulum length Moment vs tan θ · 8 runs tan θ moment slope = w·d / (Δ · tan θ) → GM, then KG Fig. 2 — weight shift, pendulum reading, GM from the slope
Lightship & stability

Vessel Inclining (VIT)

Run the experiment, capture the readings, and get the hydrostatics, the plot and the report in one pass — with the arithmetic checked as you go, not after the surveyor has left the yard.

  • Weight-shift sequencing with pendulum or U-tube readings
  • GM, lightship weight and centre of gravity the moment a run is entered
  • Outliers flagged live, so a bad run is repeated while the crew is still aboard
  • Verifiable plots and a submission-ready report

Loading computer

Stability Master

A configurable loading computer aligned to IACS UR L5. Load a sealed vessel profile and get intact stability, longitudinal strength and damage limits for any condition, in seconds — with the criteria checked against the Code, not against a spreadsheet somebody wrote in 2011.

  • Intact stability against the IMO 2008 IS Code, Part A
  • Still-water shear force and bending moment against permissible limits
  • Damage stability KG limit curves
  • Vessel data sealed with a SHA-256 hash, so a tampered profile is obvious
