This scanning system for sea containers uses air-sampling technology to detect the presence of unwanted organisms without affecting the free movement of goods. A full working prototype successfully intercepted twenty test containers randomly sent from all around the world.
There is a globally recognised need for protection against the introduction of unwanted organisms that could devastate economies and local environments. At the same time, globally connected economies are fundamentally reliant on good access to foreign markets for both imports and exports.
As a result, the movement of shipping containers represents both the biggest threat to agriculture and also the biggest success indicator of developed nations. The challenge for bio-security detection is how to intercept the unwanted bio-organism threats without affecting free trade and the movement of goods.
Scientists had developed an air-sampling technology that could detect the presence of unwanted organisms by detecting VOC markers (volatile organic compounds) at the molecular level. However, they did not have a workable design or a business proposition to wrap around the technology.
The design team studied the flow of shipping containers using time in motion analysis methods, and arrived at a system proposition that permitted the taking of air samples within the existing logistical movements.
Model sampling tools were made, and their use was verified by physical testing in actual working conditions using “Day In The Life” analysis methods. Emphasis was placed on usability, UI feedback, end-user safety, and satisfaction with the devices.
The success of these tests then allowed the design team to undertake detailed concept design work involving the refinement of exterior enclosures, internal mechanisms, sample cartridges, power supply systems, data collection, scanning and communication modules, PCBs, software, harnesses, and test rigs.
A full working prototype was built, and the technology was tested at an approved de-vanning site. Twenty random spiked containers were sent from all around the globe to the facility, containing samples of untreated timber. Container Scan successfully intercepted all of them, plus one extra contaminated shipping container that was not part of the test!
End users loved having a “weapon” to use in their job that looked the part and physically expressed their desire to probe, detect, and intercept the bad guys. Having a high-tech tool was a completely new experience for these officers, and at the end of the trial, they were reluctant to return the prototype. |
