SUB-SEA mining units employed at the world’s first large-scale submarine mine, off the coast of Papua New Guinea, will feature ABB transformers and switchgear after the engineering giant won a contract to supply the equipment to British manufacturer Soil Machine Dynamics (SMD).
The transformers and switchgear will help power three Seafloor Production Tools (SPTs) ordered by Nautilus Minerals Inc, which aims to produce copper and gold from seafloor massive sulphide deposits at Solwara 1 in the Bismarck Sea.
ABB is supplying three 6 MVA RESIBLOC dry-type transformers, and 23 pillar UNIGEAR ZS1 air insulated, arc proof, medium voltage switchboards in what is said to be “a new direction for ABB marine, which has built up its expertise through supplying marine power installations for the oil and gas industry and for vessel propulsion”.
“Up to now, ocean ROVs [remote operated vehicles] have operated on either low voltage or medium voltage levels up to 3.3kV, but they are beginning to be used at greater depths with more power demanding equipment,” said ABB projects manager Manuel Kooijman. “Greater depths and more power demand mean longer cables and using the aforementioned voltage supplies means increasing the cable diameter, which becomes expensive with the high price of copper. Manufacturers are thus switching to medium voltage supplies of 6kV and higher, which need a whole different skillset.”
Sub-sea mining also represents a new business direction for SMD.
“The mining business stream has been set up primarily to deliver the Nautilus contract, but also to engage in research and development work associated with this exciting new sector,” the company says.
“Successful delivery of this unique project and parallel development of flexible sub-sea equipment and mining methods will strategically position the company as the supplier of choice in this emerging market.”
SMD and Nautilus have a team of about 40 people who have been working since April 2010 on the design of three sub-sea vehicles and associated power, control and handling systems.
“This work builds from SMD’s prior success in the development of large, tracked sub-sea ploughs and special vehicles,” the company said.
“The first vehicle is known as the Auxiliary Cutter. A flexible production tool, one of its key tasks being to level remnant volcanic chimneys to create flat operational areas for the main production tool, known as the Bulk Cutter. The third production tool is the Collection Machine [pictured above], which gathers sized material and transfers it to the sub-sea lifting pumps.”
SMD is also supplying all deck equipment for the launch and recovery of the seafloor machines.

BIS Industries will use a FLSmidth Rahco mobile stacker to handle up to 18.2 million tonnes a year of dry tailings from Karara Mining’s Karara iron ore operation in Western Australia’s Mid West region.
Transport and logistics group Bis won a $A23 million-a-year contract awarded by Karara Mining to employ “world-leading technology” to provide tailings management services for the project, which is jointly owned by ASX-listed Gindalbie Metals and China’s Ansteel.
“The production of dry tailings represents a significant investment in water recycling capacity at Karara, allowing the project to reduce its water consumption by about a one-third,” Gindalbie said. This provided significant environmental benefits in the arid area where the project is situated.
The FLS Rahco mobile stacker will ultimately stack tailings material up to 95m high, performed in three lifts, over more than 20 years.

AUSTRALIAN manufacturer Keech Australia will next month formally release to market a new “mechanical bucket” said to have demonstrated wear-system replacement time savings on underground mine loaders at Newcrest Mining’s new Cadia East gold-copper mine in New South Wales.
The Keech Mechanical Bucket (KMB) was put on trial at Cadia East after 12 months of development by Keech and Canadian company Carriere Industrial Supply. The mine is testing a 12-cubic-metre bucket with ‘Armourblade’ edge system on two LHDs.
“The KMB bucket front with the Keech Armourblade edge system can be replaced within three hours on site. Operators simply unbolt the front section and replace it with a new one,” said the supplier’s regional and export sales manager, Mark Adams.
“Given that the edges on some buckets need to be cut off, which can take up to 35 hours,  the KMB is likely to generate significant efficiencies for underground mine applications.”

Cadia East was also evaluating actual bucket edge life, which to date had tested at about 1000 hours, Adams said. “We’re currently investigating how we can extend this to 1200 hours plus, and are looking at redesigning the corners, which are usually the fastest wearing area, through the addition of tungsten carbide inserts,” he said.

WESTERN Australian gold producer Navigator Resources is renting rather than buying additions to its truck fleet at the Bronzewing mine.
The company said it would mobilise four new Caterpillar 777F 100-tonne dump trucks from SMS Rental to work in the Cockburn openpit.
“These new trucks are intended to complement the EMECO truck fleet whilst the company completes its analysis of the mining fleet tender process,” Navigator managing director David Hatch said. The company had committed to a 12-month rental term for the four trucks with an option to extend to 36 months.
