Speed, weather, and route optimisation with live compliance check against EU ETS, FuelEU, CII, and BOG guarantee — per voyage leg. Built for LNG carriers, not generic maritime.
Most voyage optimisers show you fuel + time. VEMO shows fuel + time + EU ETS cost + FuelEU balance + CII delta + BOG guarantee exposure. Same one screen.
Cubic-law CO₂ savings vs voyage-time cost per leg. Shows the speed that minimises total P&L including EU ETS + FuelEU penalty exposure — not just fuel.
NOAA GFS + Open-Meteo integration. Avoid heavy weather that adds hull resistance and pushes CII into D/E territory. Route around, slow through, or accept — you choose with full visibility.
Natural boil-off vs propulsion demand modelled per engine type. Force BOG dispatch or reliquefaction — planned in advance, not reactively.
Every option evaluated against 5 regs: EU ETS allowance liability, FuelEU intensity balance, CII rating impact, EU MRV reporting, IMO DCS aggregation.
NYPE 2015 Cl.24 hire calculations, BIMCO ETS Clause 2023 owner/charterer 45/55 split, off-hire time-lost — all wired to the optimisation.
Trained on 1,600+ real LNG voyages. Not synthetic benchmarks. Q-Flex / Q-Max, TFDE, DFDE, ME-GI, X-DF all in the model.
Every voyage from log entry to compliance dashboard in under 60 seconds.
Load port, discharge port, cargo volume, charter type. Vessel technical specs (engine, containment, MCR) auto-load from onboarding profile.
Baseline (great-circle full speed), Cost-optimal, Compliance-optimal, Weather-optimised. See fuel + time + EU ETS + FuelEU + CII for each side-by-side.
One-click activate. Voyage becomes the operational plan. Noon reports fed back automatically compare actual vs planned.
End of voyage: EU MRV + IMO DCS entries generated. End of year: annual submissions ready for verifier review.
Based on VEMO customer data. Median LNG carrier doing 8-12 EU-touching voyages/year.
| Lever | Typical annual savings per vessel | How |
|---|---|---|
| Slow-steaming optimisation | €180k-320k | Speed reduction with hire-rate + ETS trade-off modelled |
| Weather routing | €40k-80k | Avoid heavy-weather passages, fewer off-hire hours |
| EU ETS procurement timing | €60k-140k | Buy EUAs at low prices vs surrender-day scramble |
| FuelEU pool arbitrage | €120k-500k | Match surplus vessels with deficit vessels in same DoC |
| BOG dispatch optimisation | €30k-90k | Reliquefaction vs GCU vs forced BOG chosen per leg |
| Total range | €430k-1.1M | Per LNG carrier per year |
