RGP6 Jimblebar mine project in Port Hedland, Australia
ALE were tasked with the receiving, storage, and land transportation of 230 modules, with weights ranging between 5t and 240t.
The 230 over-sized and over-mass modules were used to construct the RGP6 Jimblebar Iron Ore project.
Fabricated in China, these modules were shipped from Tianjin to Port Hedland, Western Australia. The 230 modules were received in over 11 shipments, with the first received in June 2012 and the last modules were delivered to site in Newman by late February 2013.
The modules were received on SPMTs at Port Hedland Port Authority (PHPA), before being transported within the PHPA grounds and set on stools to await ground transportation on conventional trailers. Configurations of both SPMTs and conventional trailers was dependent on each modules’ dimensions and weight – the latter to accommodate for Western Australia’s axle-loading restrictions. The largest module was 42.5m long, 13.5m wide, 14.5m high and 227t in weight and the largest trailer configuration comprised of a 4 file 28 row (6.3m wide, 42m long).
Transportation from Port Hedland to the Jimblebar Mine site (totalling 450km) was splitinto four segments, each requiring one night of travel time. The first of which saw the modules (one per trailer) travel in convoy from Port Hedland to Boodarie – a staging area located 25km outside of Port Hedland. From here convoys to the Jimblebar site are formed, with the highest priority items given precedence in earlier convoys to site.
As public roads were utilised for ground transportation, and Western Australia law states that cargo over 8.5m wide cannot travel during daylight hours, ALE organised and conducted night-time convoys within a rolling road-block under the guidance of Police Traffic Escorts. ALE faced the challenge of reserving and obstructing public roads and required the cooperation of multiple public stakeholders and external bodies.
ALE had to work alongside various transport companies to determine suitable transport dates and road- access into and out of the world’s largest bulk export harbour every night a convoy took place on the road. The route also had to negotiate multiple railway crossings of various mining companies in a prompt manner as to not cause delay to their deliveries.
ALE had a dedicated SPMT crew located at the Jimblebar site on a full-time basis, equipped with 40 axle lines of SPMT trailers and 12 axle line of compatible spacer decks. As modules were placed on stools upon arrival at Jimblebar, SPMTs then transported the modules to various site locations – sometimes up to 5km in distance.
