NYK uses vessel models to support route and speed decisions

Read the source ↓What the company did
Sofar reports NYK using Wayfinder for car-carrier operations and expanding to tankers. Custom weather forecasts and vessel-performance models provide daily route and speed guidance. A separate platform article explains machine-learning calibration from noon reports, without disclosing NYK’s specific trained model.
How it went
The provider reports a 33-leg tanker trial in 2025/26 saving 335 metric tonnes of fuel and avoiding 1,056 metric tonnes of CO2 before the rollout. The release does not explain the savings baseline or provide independent verification.
Worth knowing
- Guidance supports masters and shore teams; the platform-level method article does not establish NYK’s use of every newly announced feature.
- For your desk: Check arrival obligations, forecast timing and safe-navigation limits before choosing a route or speed change. Compare realized fuel use with an explicitly recorded baseline.

Supporting evidence and review
Human review required
- Check arrival obligations and safe-navigation constraints before adopting a recommendation.
- Evaluate realized performance against a comparable baseline.
Evidence & limitations
- Provider-published rollout and trial account; no independent savings verification.
- Machine learning method evidence is platform-level; it does not disclose NYK’s trained model.
- A routing recommendation supports, rather than replaces, the master’s judgment.
