SPG ISPS — Stowage Planning
SPG ISPS is a maritime vessel operations engine available as a SaaS platform and a developer API. It computes hydrostatics, stability, and load layout compliance in real time for both liquid tankers and container ships.

What this platform does
Each capability is a deployed module — not a feature on a roadmap. Engagements typically begin with a 4-week scoping exercise to confirm fit against your operational data and constraints.
Hydrostatic & stability viewer
Draft, trim, heel, and transverse metacentric height curves are computed dynamically as cargo is loaded or discharged — using buoyancy integration at 21 longitudinal stations.
Hull structural stress dashboard
Shear Force and Bending Moment curves are plotted across the hull, with automatic SOLAS threshold flags raised before structural limits are breached.
Dangerous goods segregation auditor
Hazardous cargo placements are audited in real time against IMDG segregation rules — flammables, explosives, and oxidising classes are kept separated by design, not inspection.
Intelligent stowage plan optimiser
An adaptive search engine generates optimal stowage plans, avoiding overstows based on discharge port sequence and minimising vessel turnaround time.
Voyage P&L ticker
Live dynamic estimates of fuel consumption, handling rates, and net profit per voyage update in the dashboard as stowage decisions evolve.
