Cape Lambert Port B - Capital Dredging Works

BMT has been involved in a variety of tasks related to the expansion of facilities at Cape Lambert in order to increase the iron ore output capacity at the port.


Rio Tinto Iron Ore is currently undertaking expansion of the Cape Lambert port facility, which will increase the ports capacity from 80 million tonnes to 183 million tonnes by 2015. This project is part of Rio Tinto’s current plans to increase their annual capacity in the Pilbara region to 353 Mtpa, making this the largest mining project ever undertaken in Australia.

The expansion of the Cape Lambert port will be achieved through the construction of a new 1.8 km jetty and four-berth wharf to run parallel to the existing wharf.

The building of the new facility requires a capital dredging programme of more 3.5 Mm3 of material from the new berth pockets, turning basin and shipping channel, as well as significant marine and on-shore construction works.

BMT was engaged to provide onsite dredge supervision and project management for this ~$100 M dredging project using the cutter suction dredge, Castor, and trailer suction hopper dredge, Rotterdam.

With the works being carried out concurrently with other significant marine works (including construction of a new loadout wharf and associated marine piling) and in close proximity to the operating Cape Lambert Port A facility.

BMT project engineers were key in the development of practical and innovative solutions to manage contract interfaces.
