MariTrace has compared the official export data for Port Hedland, as released by the Pilbara Ports Authority, to MariTrace‘s own Commodity Tracker data. This study has revealed that MariTrace’s data accuracy is within 98% of the official figures on average over the last 24 months.
In the graph below, the blue line indicates MariTrace’s calculation of the amount of iron-ore exports compared to the official data, shown in red.
While this accuracy is impressive in itself, MariTrace is generating these numbers as the vessels move out of the berth. For all intents and purposes, the data is live.
Official monthly numbers for port export data are often released weeks after the month has completed. In many it’s released many months later and, quite often, it is never released. Even if port-agents are communicating that data as it comes in, the process is notoriously difficult to automate. Not only that, but it relies on having a contact inside every port that you want to track. And a reliable contact at that.
MariTrace gets around this problem by examining the AIS signature of the each vessel. It compares that data against the proprietary geospatial data that it holds for these ports. By comparing these two valuable data-sets, MariTrace can not only determine which commodity a vessel is likely to have been loading or discharging at that port, but how much it is loading or discharging. And, since the AIS data is received live, the calculations are made as the changes occur. No need to wait, anymore, for official numbers to be released.
This gives an unparalleled glimpse into the worldwide movements of vessels at a macro or micro level. In many cases, MariTrace can determine how long vessels waited at anchor to get to the berth, and how long they spent at each berth. The result of this is a detailed insight into vessel behaviour.
Knowing where a vessel has been to pick up a commodity is one thing, but MariTrace can also determine where that vessel went to next.
For example, the above chart shows where the iron ore exports from Port Hedland have been ending up. The graph below shows how this has been changing over the last two years.
This wealth of data isn’t necessarily restricted to a single port, or even a single country. Users can define their own areas of interest and examine all the activity within that area at a level of detail useful to them. So, a user can look at that picture as a whole, or examine individual vessel movements and activity within specific berths.
With such a level of accuracy, and at such different scales, MariTrace’s rich seam of proprietary data gives it a solid foundation on which to provide essential intelligence to any industry – whether directly involved in maritime or not.
