Feature-by-feature comparison of two maritime compliance and voyage-optimisation platforms — VEMO FuelIQ (LNG-native, solo founder, Y-2026 startup) vs ZeroNorth (established, tanker-first, 200+ staff).
Pick ZeroNorth if: Your fleet is majority tanker or bulk (they built for that first). You need a big-vendor procurement path (large enterprise buying committees find easier internal justification). You want commercial+operational optimisation across a 50+ vessel fleet with in-house data teams.
Pick VEMO FuelIQ if: Your fleet is majority LNG carriers. You value LNG-specific depth (9 engine models, 4 containment systems, BOG dispatch, engine-type methane slip) over broad multi-cargo generality. You want per-vessel pricing that starts at €199/mo, not enterprise-only. You want a founder you can email and a product cycle that ships weekly.
| Dimension | VEMO FuelIQ | ZeroNorth |
|---|---|---|
| Target vessel type (primary) | LNG carriers | Tanker + bulk |
| Engine models supported | 9 (ME-GI, X-DF, LGIP, LGIA, DFDE, TFDE, steam, MEGI, Otto) | 3-4 generic categories |
| LNG containment types | 4 (Moss, NO96, Mark III, Mark III Flex) + age adjustment | Generic BOR factor |
| BOG dispatch modelling | Per voyage leg (natural + forced + reliq + GCU) | High-level only |
| Engine-type methane slip | Per engine (76-91 gCO₂e/MJ range) | Single LNG factor |
| Pilot fuel accounting | Yes (dual-fuel MGO) | Approximated |
| EU ETS coverage | Full (phase-in + scope + live EUA) | Full |
| FuelEU Maritime | Full + pooling arbitrage | Full |
| IMO CII + rating trajectory | Full + year-end projection | Full |
| IMO EEXI | Full (LNG-specific formula) | Full |
| EU MRV / IMO DCS auto-gen | Yes | Yes |
| Sea Cargo Charter alignment | Yes | Yes |
| Weather routing (built-in) | NOAA GFS + Open-Meteo | Proprietary + partners |
| Charter party math (NYPE/BIMCO) | Yes | Limited |
| Pricing (entry tier) | €199/mo (1 vessel) | Enterprise sales only |
| Fleet-only pricing available | €999/mo (15 vessels) | Enterprise only |
| Free trial | 30 days, no credit card | Sales-led evaluation |
| Onboarding time (1 vessel) | ~30 min self-serve | 2-6 weeks with vendor |
| API integration | REST + Vessel API keys | Full API |
| Deployment speed | Weekly product releases | Quarterly release cadence |
| Fleet management scale (comfortable ceiling) | ~50 vessels | 500+ vessels |
| Language support | English | English + JP + others |
Large mixed fleets (tanker + bulk + container) where LNG is a minority. Enterprise procurement (they have the vendor-management infrastructure large operators require). Multi-language operations. Fleet sizes above 50 where their scale advantages compound. Integration with existing large PMS/ERP stacks (SAP, IBM Maximo, Star Information Systems).
LNG-majority fleets where engine-type methane slip, containment BOR, and forced BOG dispatch are 15-20% of total compliance accuracy. Operators who value pricing transparency (published tiers vs enterprise-only). Small-to-mid LNG fleets (5-50 vessels) that get lost as "small accounts" in enterprise vendor prioritisation. Fast iteration — weekly releases vs quarterly.
Core EU ETS calculation. FuelEU intensity math. IMO CII + EEXI. MRV + DCS auto-generation. Weather routing (both use NOAA + partners). Sea Cargo Charter alignment. Neither is dramatically better for the "generic" regulation stack — the differentiation is in LNG-specific depth and pricing model.
No credit card. Onboard 1 LNG carrier in under 30 minutes. See exactly how the engine-type methane slip + BOR curves + BOG dispatch modelling changes your numbers vs a generic tool.
