Modern Containerized Bulk Handling
Recent developments in containerized bulk handling technology removes many of the challenges associated with conventional containers and offers opportunities for increased efficiency.
This new system uses specifically manufactured, open top containers which are designed with standard ISO footprint dimensions, a removable rigid lid, no internal ledges or stiffeners, and painted with a high-release coating (ensuring 100% of the cargo wet or sticky is discharged).
This new container design allows for easy filling of bulk cargo from the top - using mobile equipment or an automated loading system, and for a simple discharge of cargo using speciality spreaders. The spreaders pick up the box, remove the lid, and in one motion spin the container and dump the cargo.
Using this system provides a low cost, simple option for moving bulk cargo to export without the need to develop a conventional bulk terminal logistics option. For example, loading product at a mine, and discharging it directly into the open hold of a bulk carrier vessel at port. The container and spreader assets require less capital to implement and are fully transferrable to other operations.
Why then has this not been universally adopted, but remains rather limited to a handful of basic direct-to-ship installation in Australia, South America and Africa?
In my experience, I have found that some clients’ apprehension to “trying something new” is a result of focusing solely on the new equipment and an uncertainty in how to implement this concept for their application. When presented with the bigger picture – the development of an integrated logistics solution that is optimized for geography, existing infrastructure and specific commodity – they are more open to this approach.
Have you had similar experiences with the introduction of other new technology?
In my next post, I will discuss how we used this holistic approach at Las Bambas copper mine in Peru.

8 年Joel: Interesting article. We are looking at implementation of such a system to handle mineral concentrates in Tasmania.

8 年Hi Joel Thanks for the interesting article. On a recent Peruvian mining project we reviewed using this technology including visiting a northern Chile port (Mejillones) to see the system in use. In our specific case, the economics of using a conventional bulk materials handling system at an existing port proved to be a more viable option. Our considerations during this assessment included factors such as: a) The environmental requirements / permitting regulations that applied to the project b) Capex c) Opex d) In country norms / new technology adoption (as you have mentioned) e) Variability in the rate of concentrate production (in our case, the average to peak production varied by a factor of about 2.5, increasing the number of containers needed for peak years and thus the associated capex) It is worth highlighting that for many projects, minimising upfront capital spending is a key project driver. In our case, the port charges became part of the operating costs which reduces the project's upfront capital requirements. Of course, the overall NPV also needs to be considered as part of these decisions. kind wishes JohnM
