Nautilus successfully progressing subsea equipment trials in PNG

SUBSEA miner Nautilus Minerals Inc. has reported it has been successfully undertaking submerged trials for the company’s Seafloor Production Tools, with the final machine, the Bulk Cutter, due to finish trials next month. Submerged trials of the Collecting Machine and Auxiliary Cutter were completed late last year. To date the Bulk Cutter has completed commissioning of the power and control system, on-shore functions testing, submerged function testing and submerged endurance

Siemens achieves breakthrough with 3D printed gas turbine blades

SIEMENS has achieved a breakthrough by finishing its first full load engine tests for gas turbine blades completely produced using Additive Manufacturing (AM) – more commonly known as 3D printing – technology. The company successfully validated multiple AM printed turbine blades with a conventional blade design at full engine conditions. This means the components were tested at 13,000 revolutions per minute and temperatures beyond 1,250 degrees Celsius. Furthermore, Siemens tested

CSIRO says its new technlogy fills an important gap in gold detection market

AUSTRALIAN scientific organisation the CSIRO is partnering with Chrysos Corporation to bring to market its powerful PhotonAssay X-ray gold detection technology, setting its sights on a slice of the $1 billion global gold assay business. Analytical services are an essential part of the mining value chain, from exploring for new deposits CSIRO’s lead inventor of the technology and Chrysos Chief Technology Officer, Dr James Tickner, says this new approach fills

OTDF secures eaglewood patent and rubber licence

THE Ok Tedi Development Foundation has moved a giant step closer towards achieving its economic development sector goals by securing an eaglewood patent and rubber licences for the benefit of Community Mine Continuation Agreement (CMCA) and all other communities in the Western Province. OTDF chief executive officer Ian Middleton recently signed an “Exclusive License Patent Agreement” with Cultivated Agarwood Limited (CAL) providing exclusive rights to the agarwood producing CA Kit

Maximising Mining Operational Efficiency Through Satellite

THE mining industry is seeing an increasing trend to support remote automation processes and consequently to meet growing requirements for bigger bandwidth. For business success, today’s mining organisations must rely on best-of-breed network infrastructure to deliver the same performance levels as corporate head office, ensuring remote operations do not end up isolated. An essential element in mine site connectivity for more than three decades, satellite communications have firmly secured their

Testing underway for Nautilus’ SSLP

NAUTILUS Minerals completed assembly of its Subsea Slurry and Lift Pump (SSLP) in early February and has since commenced factory acceptance testing (FAT) at the GE Oil & Gas manufacturing facility in Houston, USA. The SSLP is for the company’s Solwara 1 project which is owned by a joint venture comprising Nautilus (85 per cent) and Eda Kopa (Solwara) Limited (15%). Nautilus chief executive Mike Johnston said the SSLP is

Breaking records in PNG’s mining sector

CUSTOMISED mud programs designed by Tiger Fluids have helped Downer EDI Mining break site depth and metre production records at the Highlands Pacific Star Mountains exploration site, Tiger says. The drilling fluids company’s manager in Australian and Papua New Guinea, Rhys Clarke, said the Star Mountains exploration sites of Olgal and Kumkom were being drilled using an Alton HD900 and a Boart Longyear LF70 drilling rig. “Before the drilling starts,

No tears in onion jack stressing

ENSURING reliable hydraulic power to an onion jack can be a challenge where there is no mains electricity available, especially when these jacks are used to stress steel strand cables in concrete structures. The onion jack process is common to multi-story or slab construction where access is inhibited by beams or other obstructions. In such cases, worksite personnel cannot use stressing cables’ standard live end and dead ends. The method

Simulator supports safer skies

AN AIR traffic control training simulator worth K13 million has been installed at a PNG Air Services facility for the training of staff in Papua New Guinea. The simulator provides a realistic experience of both Jacksons and Nadzab air traffic control towers and their respective operating environments, PNG Air Services said, with the Tokua, Madang, Goroka and Hagen airports to be added in due course. The simulator has the capability

A step closer for Nautilus

MINING minster Byron Chan is full of confidence that Nautilus Minerals will be able to proceed with its drilling activities on the floor of the Bismarck Sea after a visit to the Soil Machine Dynamics (SMD) workshop in Newcastle, in the United Kingdom. SMD is manufacturing and assembling the three seafloor mining tools needed for the offshore mining campaign. These include the auxiliary cutter, responsible for creating the mining surface,
