Digital Twin

A vessel the software understands

A parametric model of the hull drives the 3D shell, the deck plans and the tonnage figure. Type the particulars; the geometry follows.

Geometry, tonnage, plant

Tonnage computed, not typed

Gross tonnage integrates from the enclosed volume under the 1969 Tonnage Convention, with live headroom to the 500 GT threshold.

One hull, every view

A single hull function draws the 3D shell, each deck plan, the profile and the body plan. The views cannot disagree.

The SFI equipment tree

Plant organised by SFI group codes, the vocabulary AMOS-generation engineers already speak.

Colour by condition

Flip the whole vessel to needs-attention, criticality, defects or due maintenance, and click any machine for its record.

Fit-out in minutes

A 38-item standard plant list arranges twin engines, gensets and gear into their compartments, ready to drag into place.

Alarms in bridge vocabulary

Emergency, alarm, warning and caution tiers follow IMO bridge-alert management, over a live 3D vessel.

From particulars to plant

Type length, beam, depth and a hull family. One surface then draws the shell, integrates the tonnage, cuts the deck plans and files the plant under SFI codes. Four views, one source of truth.

Hull surface

Six parametric hull families, from displacement to planing. The sheer follows the ICLL Reg. 38(8) standard profile and the bulwark floors at 1.00 m per Reg. 25.
