How the ships move.
Which ships carry Venture Global's cargoes, how long they take to come back, which routes they appear to use, how long they spend at the berth, and what weather does to their speed.
How much is carried by Venture Global's own ships?
Most frequent ships
Definition. Own ships are the seven Venture-named tankers in the DOE data, consistent with the 10-K (nine contracted, seven delivered by end-2025). Chartered ships carrying Venture Global's cargoes count as third-party here.
How long until a ship loads again, and which routes do Asia voyages take?
Method. A round trip runs from a Venture Global loading to the same ship's next loading at any U.S. terminal (gaps over 150 days are excluded as other trading). For Asia voyages the implied average speed is computed for each route; a route is plausible when it implies 13–20 knots, and the voyage is labeled only when exactly one route fits. Limits. Waiting time, slow steaming and calls at other ports all lengthen trips, so this infers routes, it does not observe them.
How long do ships wait and berth at Calcasieu Pass? (AIS, October 2023)
Method. A berth stay is at least 6 hours within 1 km of the berths at under 1 knot. Waiting is time stopped within 60 km before berthing. Each stay is matched to a DOE departure by ship name within a day; when the AIS name differs (renamed or abbreviated ship), the only unmatched DOE cargo that day is used and labeled.
Do waves and wind slow the ships down?
Method. Open-water positions (over 80 km from the terminal, above 6 knots) within six days of a berth stay, joined to hourly modeled wave height and wind on a 1° grid (Open-Meteo). Ship fixed effects; standard errors clustered by ship. Limits. One calm month and a dozen ships. Speed is mostly a commercial choice, so a small or zero effect is unsurprising; a full year of AIS would be needed to measure storm effects or fuel burn, which is not public.
What does the voyage cost per MMBtu?
Low case uses low charter rates and fees with the highest speed; high case the reverse. Assumptions are listed on the commercial page.
