A public overview of the data categories used across TankerMap, with visible source categories, update cadence, coverage and access paths. This page describes website and public API data surfaces; it does not expose private provider credentials or internal ingestion details.
Live and recent AIS-derived positions for oil tankers, LNG carriers and related tanker classes shown on the TankerMap map and vessel pages.
Canonical tanker fleet records including vessel identity, flag, type, dimensions where available, live status and last observed state.
Observed arrivals, departures and in-port tanker activity for LNG terminals, crude export terminals and monitored ports.
Transit counts and tanker movement analytics for strategic passages including Hormuz, Suez, Malacca, Bab el-Mandeb, Gibraltar and Panama.
TankerMap watchlist flags for vessels appearing in sanctions/compliance-related monitoring views.
Daily OHLC bars for supported energy benchmarks such as Brent, WTI, TTF, JKM and added commodities (Urals, LNG Brent, Henry Hub, EU margins) used for tanker market context.
A small hub for factual TankerMap reports and methodology pages. No new indexable /reports page is created yet: the approved public hub is this /data#reports section, while the standalone weekly brief remains noindex until separate quality and sitemap approval.
A generated weekly brief using TankerMap chokepoint transit aggregates for Hormuz, Suez, Bab el-Mandeb, Malacca, Panama and Gibraltar.
Observed tanker arrivals, departures and in-port activity for monitored crude, product and LNG ports.
How TankerMap explains AIS tracking, vessel freshness, fleet classes, limitations and practical tanker-monitoring workflows.
Energy market pages that connect tanker movement context with Brent, WTI, LNG, gas and refined-product benchmark pages.
Definitions for AIS position, live vessel, port call, shipment estimate, chokepoint transit, DWT, draught, freshness and limitations.
Short definitions for TankerMap terms covering AIS positions, live vessels, fleet classes, port calls, shipment estimates, chokepoint transits, DWT, draught, destination, data freshness, confidence and limitations.
A timestamped vessel position observation derived from AIS broadcasts. It can include latitude, longitude, speed, course and position time; gaps or delays can occur when reception or upstream feeds are limited.
A vessel with a recent TankerMap position inside the public freshness window. Live means recently observed in TankerMap data, not guaranteed continuous tracking.
A normalized tanker category used for browsing and filtering, such as LNG carrier, VLCC, Suezmax, Aframax or product tanker. The label comes from vessel records and TankerMap classification rules.
An observed or inferred tanker arrival, departure, in-port state or expected arrival for a monitored port or terminal. Port-call tables can combine AIS zone events, port metadata and recent vessel observations.
A derived cargo-volume point used on selected analytics pages when direct shipment data is unavailable or incomplete. Estimates are labeled separately from reference monthly shipment rows.
A capacity-equivalent liquid-petroleum estimate derived from crude-oil tonnes at 7.37 barrels per tonne and oil-product tonnes at the 7.40 barrels-per-tonne IEA Non-Crude fallback. Total oil is crude plus oil products only; LNG is excluded. Daily charts can show a complete trailing 7-day average, while monthly tonnes are divided by the actual number of calendar days.
A TankerMap transit observation counted when a vessel movement matches a configured maritime passage such as Hormuz, Suez, Malacca, Bab el-Mandeb, Gibraltar or Panama.
DWT is deadweight tonnage from vessel records where available. Draught and destination are AIS fields reported by the vessel and can be stale, missing, abbreviated or manually entered by crew.
Freshness describes how recently TankerMap observed or refreshed a record. Confidence and limitations reflect that AIS, port and market datasets can contain delays, gaps, duplicate records or destination errors.
The map shows the latest AIS positions inside a live freshness window. /vessels, /fleet and /sanctions count canonical vessel profiles with valid coordinates. Ports and chokepoints use separate geofences and aggregate jobs. For that reason, live counts, fleet counts and analytics counts can differ temporarily while feeds refresh or AIS coverage varies by region.
