Trade flow identification and tracking
Oceanbolt’s trade flow algorithm is the central algorithm in the platform and forms the basis for all trade flow and vessel status data.
The trade flow algorithm works by first generating events for every vessel, for example, when a vessel enters/exits a polygon or when it changes its draught or destination. Based on these events, the trade flow algorithm generates port calls like a load event in Santos or a discharge event in Tianjin. Finally, port calls are tied together to voyages, for instance, a grains voyage from Santos to Tianjin. From the ongoing events information, the algorithm infers the current cargo status and historical voyages on a vessel level.
The algorithm infers the commodity group and grade from our polygon layer that captures which commodities are being imported/exported at the terminal level. The specific volume is inferred based on a combination of vessel capacity, tons per inch calculations of draught changes, and past observations on a terminal and vessel level.
