Arctic Shipping Route Planner
Forecast sea-ice thickness, route transit time and insurance risk for cargo vessels transiting polar shipping corridors.
Why this matters
Forecast sea-ice thickness, route transit time and insurance risk for cargo vessels transiting polar shipping corridors.
This model is adapted from an internal scenario-planning tool, distilled here into three linked calculations that mirror how real operators, engineers and analysts reason about the system.
How the model works
- Ice concentration (%) — Estimated ice thickness at −18°C and 12 m/s wind — thicker ice needs a heavier icebreaker escort class.
- Vessel speed (knots) — Transit time for a 5,600 km route including a fixed 36-hour weather buffer.
- Fleet value at risk ($M) — Seasonal insurance budget at a fixed 3.2% coverage rate and 0.28 baseline risk index.
Reading the results
Each control drives one of three underlying formulas taken from the source engineering model. Moving a slider recomputes its metric instantly and updates the 3D bar in the simulation — taller, brighter bars mean the system is closer to its optimum operating envelope. Try pushing each parameter to its extreme to see where the model breaks down or saturates.
Frequently Asked Questions
What is arctic shipping route planner used for?
Forecast sea-ice thickness, route transit time and insurance risk for cargo vessels transiting polar shipping corridors.
Is this a real-world engineering model or a toy?
The underlying formulas are simplified versions of real planning heuristics used in this domain — accurate enough to show the right trends and trade-offs, but not a substitute for full engineering simulation software.
Can I use my own numbers?
Yes — every slider in the simulation maps directly onto one of the model's input variables, so you can explore scenarios well outside the defaults shown here.
Why does the bar height saturate at the extremes?
Each metric is normalised to a 0–1 range against a realistic reference ceiling from the source model, so very large inputs will visually cap out even though the underlying number keeps growing.
