Patent number: 9957694Abstract: A system and method for stockpiling material on the seafloor, the system and method using seafloor collection machines, such auxiliary or bulk cutters or collection machines, to capture seafloor material to be stockpiled. The captured seafloor material is carried in slurry form over a flexible transfer pipe to an outlet at a desired seafloor site. In a preferred form the outlet is mounted in a seafloor stockpiling hood that sits on the seafloor at the desired seafloor site and captures and contains slurry from the outlet while allowing egress of water. The captured seafloor material can then be extracted to a surface vessel.Type: GrantFiled: June 15, 2012Date of Patent: May 1, 2018Assignee: Eda Kopa (Solwara) LimitedInventors: Glen Robert Jones, Daal Hallam Jaffers, Roland Gunter Berndt

Patent number: 9260964Abstract: A seafloor auxiliary mining tool for use in a seafloor mining system. The seafloor auxiliary mining tool has a seafloor locomotion system enabling traversal of the seafloor. Umbilical connections receive power and control signals from a surface source. A boom mounted auxiliary cutting tool is configured to cut extremities of a seafloor deposit. Cuttings produced by the auxiliary cutting tool are sized by sizing means, to ensure such cuttings are no greater than a desired size.Type: GrantFiled: June 17, 2011Date of Patent: February 16, 2016Assignee: Nautilus Minerals Pacific Pty LtdInventors: Glen Robert Jones, Antony Eliot Inglis, Anthony Paul O'Sullivan, Michael Howitt, Glen Smith, Roland Gunter Berndt, Daal Hallam Jaffers, Nicholas William Ridley

Patent number: 9243497Abstract: A system for seafloor mining. A seafloor auxiliary mining tool works a seafloor site to prepare a bench, and deposits cut ore in a gathering area. A seafloor bulk mining tool undertakes production cutting of a bench and deposits cut ore in a gathering area. A seafloor gathering machine gathers cut ore deposited in the gathering area and pumps gathered ore as a slurry to a riser base. A riser and lifting system receives slurry from the gathering machine and lifts the slurry to the surface. A surface vessel receives slurry from the riser and lifting system.Type: GrantFiled: June 17, 2011Date of Patent: January 26, 2016Assignee: Nautilus Minerals Pacific Pty LtdInventors: Glen Robert Jones, Antony Eliot Inglis, Anthony Paul O'Sullivan, Michael Howitt, Glen Smith, Roland Gunter Berndt, Daal Hallam Jaffers

Patent number: 9243496Abstract: A seafloor bulk mining tool for production cutting of a seafloor bench. The tool uses a tracked locomotion system to travel across a seafloor bench. Power and control interfaces receive power and control signals from a surface source. The tool has a drum cutter for cutting the bench, and a sizing grill adjacent the drum cutter for sizing cuttings as they are produced by the drum cutter. A drum shroud may also be provided to help contain cuttings. A suction inlet can be used to capture cuttings as they are produced, for example in conjunction with a spade and augers.Type: GrantFiled: June 17, 2011Date of Patent: January 26, 2016Assignee: Nautilus Minerals Pacific Pty LtdInventors: Glen Robert Jones, Antony Eliot Inglis, Anthony Paul O'Sullivan, Michael Howitt, Glen Smith, Roland Gunter Berndt, Daal Hallam Jaffers, Nicholas William Ridley, Ian Maskell

Publication number: 20150367917Abstract: A production support and storage vessel is provided, as well as a method of processing material, such as ore, gathered from the seafloor using such a vessel. The production support and storage vessel has facilities to receive ore from the seafloor, process it, and store the ore in bulk storage silos. Additionally, the production support and storage vessel has a ballast capability and system to ballast the vessel down to a full operational draft. When needed, typically approximately weekly, a transport vessel is moored to the production support and storage vessel and the production support and storage vessel offloads the stored ore using a conveyor system.Type: ApplicationFiled: November 28, 2013Publication date: December 24, 2015Inventors: Daal Hallam Jaffers, Michael Howitt, Roland Berndt

Publication number: 20140137443Abstract: An apparatus for seafloor stockpiling that has a slurry inlet that receives slurry from a seafloor tool via a slurry transfer pipe and walls that, together with the seafloor, define a cavity having a stockpiling volume. The walls are made substantially of a water permeable material, such as a filter fabric or geotextile, that captures and contains seafloor material present in slurry received from the slurry inlet, while permitting egress of water from the slurry. In a preferred form the seafloor stockpiling device is a hood with an open bottom that is located on a seafloor surface.Type: ApplicationFiled: June 15, 2012Publication date: May 22, 2014Applicant: NAUTILUS MINERALS PACIFIC PTY LTDInventors: Glen Robert Jones, Daal Hallam Jaffers, Roland Gunter Berndt, Paul David Griffiths, David Edward Milburn
