DriftLogic pulls live wind, wave and current data the moment you log an incident, and turns it into a 24-hour drift forecast with an honest uncertainty envelope — not a guess drawn in a briefing room.
$24.99/month or $234.99/year. Cancel anytime. Built and hosted in Cape Town.
Response teams already know the tides and the coastline. What's missing is a fast, defensible answer to one question: where does this particular spill end up, at this particular hour, on this particular current.
Manual drift estimates take time to assemble and go stale the moment the wind shifts. By the time a map is drawn, the slick has moved past it.
Wind and current forecasts carry error bars. A response plan built on one best-guess track can send crews to the wrong stretch of coast.
Authorities and clients need a clean incident record and a forecast report — assembled by hand, usually after the fact, usually under pressure.
No manual data entry, no separate weather lookup. Log the incident and DriftLogic does the rest.
GPS, manual coordinates, or tap the map. Set pollutant type, estimated volume and severity — takes under a minute in the field.
DriftLogic queries real marine forecast data for the exact coordinates and time — live data for recent spills, historical archive data (back to 1940) for older ones.
open-meteo marine + ERA5 archiveAnisotropic diffusion, wind drag, Stokes drift and weathering decay run three times — nominal, and two perturbed runs — so you see a realistic spread, not false precision.
Hour-by-hour positions, a bounding envelope across all three runs, and automatic coastline beaching — so the forecast stops realistically at the shoreline, not through it.
A real, documented ship-to-ship transfer incident near Brenton Island was used to sanity-check the model: pipe failure during bunkering, 3,000 L spilled at the boundary of the Addo Marine Protected Area.
The known outcome — contained, no beaching, no oiled birds at St Croix or Bird Island — matches what the model predicts: south-westward drift on the Agulhas Current, with the uncertainty envelope clear of the island group.
Full incident logging, live forecasting, PDF exports and push alerts on every plan — the only choice is how you'd like to pay.
Yes. Billing and cancellation are handled through Creem's secure billing portal, accessible from your Settings once you're subscribed. Cancelling stops future billing; you keep access until the end of the period you've already paid for.
Yes. Each account's incidents, forecasts and photos are scoped to that account — nobody else on your team sees your data unless you're on an admin-managed workspace.
DriftLogic is a PWA — install it to your phone's home screen and it will log incidents offline, syncing automatically once you're back in signal.
Low Sulphur RMG 180 (bunker fuel) is the primary, most-tuned profile. Chemical, sewage/waste water and other generic profiles are also available with their own diffusion and weathering behaviour.
