No use cases recorded yet. See the StormGeo review.

ZeroNorth

  • A tanker operator wanting speed decisions that account for the freight market rather than optimising fuel in isolationnot StormGeo
  • A bunker buyer testing supplier quotes against independent fair value pricing before fixing a stemnot StormGeo
  • An owner needing EU ETS and FuelEU Maritime reporting derived from the same voyage data that drives operational decisionsnot StormGeo
  • A charterer evaluating which vessel to take on a cargo based on projected voyage economics rather than on nominal specificationsnot StormGeo

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

StormGeo

  • No longer independent as fully owned subsidiary of Alfa Laval since June 2021
  • Primarily Europe-based with less established presence in Asian maritime markets compared to Weathernews
  • Focused on commercial and industrial sectors rather than consumer weather services

ZeroNorth

  • ZeroNorth reported a net loss of roughly $65m for the 2024 financial year, deepening by around 57 per cent, so a multi-year fleet commitment should include contractual protection on continuity and pricing.
  • The company consolidated operations during 2025, liquidating a Norwegian subsidiary, which is prudent cost control but means local presence and account continuity may not be what was originally sold.
  • Pricing is per vessel and per module, so the headline vessel figure understates the cost of an owner who wants voyage, bunker and emissions capability across a fleet.
  • Recommendation quality depends on the quality of noon reports and vessel data supplied, and an owner with poor reporting discipline will get poor optimisation regardless of the algorithms.
  • It sits between technical performance tools and chartering systems and fully replaces neither, so most owners run it alongside an existing voyage management system and pay for overlapping capability.
