Sandwell is actively involved in engineering every link in the coal chain, from mine to end-user:
- at the mine: planning, site development, coal handling systems, truck and railcar loadouts, power generation, water supply and drainage, townsite planning, site preparation and structural engineering for process plants;
- rail transportation: through International Rail Consultants, a Sandwell joint venture, we provide comprehensive railway planning, management, engineering and operations;
- marine export terminals: a major portion of the world's seaborne coal passes through terminals we have either engineered or modified;
- stockyards: from master planning for new facilities to the optimization and/or expansion of existing stockyards;
- railcar and truck unloading: our specialists stay abreast of the latest developments in these key coal chain activities;
- import terminals: we have worked on facilities around the world, typically for coal-fired thermal power or steel plants.
Sandwell's work is distinguished by the customizing of key elements, such as as stackers and shiploaders, for unusual and extended applications.
P.T. Indominco Mandiri, East Kalimantan, Indonesia
Mine and terminal facilities
A new marine terminal enables the export of up to 3.5 million tonnes of coal annually from the Bontang mine, some 40 km away. Stacking, storage and reclaim systems were designed for both the mine and port stockyard, from which a 6.4 km overland conveyor carries coal to a 2 km marine trestle and deep water. Port facilities include a 2,000 t/h shiploader for Panamax vessels.
Port of Long Beach, California Terminal
Long Beach expansion
For the Pier G Bulk Terminal expansion at the Port of Long Beach, California, Sandwell designed and engineered a 275 m long storage shed for up to 175,000 tonnes of coal, with reclaim and 1,000 m of pipe gallery conveyors connecting to the existing shiploading system.
Antelope Coal Company
EPCM mine expansion
The new facilities at Antelope's open-pit coal mine comprise a single-pocket truck dumping station with feeder, crusher and overland conveyors to two existing over-track rail loadout silos. The coal crushing and conveying capacity was increased from 12 to 19 million TPA with provision for an eventual expansion to 30 million TPA.
Ridley Terminals Inc.,Prince Rupert, British Columbia
EPCM export terminal
This 12 Mt/a terminal in northern B.C. features a train unloading system with thaw shed, frozen-coal handling equipment and dust extraction and collection systems; two 6,000 t/h stacker/reclaimers; a 2,000 tonne capacity surge bin; dual quadrant shiploaders; and a computer-based terminal operations management system
