Abstract: Disclosed are various examples for enrollment of gateway enrollment for Internet-of-Things (IoT) device management. In some examples, a client device receives a gateway management installation package from a management service. The client device installs a gateway management application to the gateway device using the installation package. Enrollment credentials are entered through a user interface generated using the gateway management application and shown on the client device. The client device instructs the gateway management application enroll the gateway device with the management service. Usage of the enrollment credentials prevents a user from being exposed to gateway credentials that authenticate communications between the gateway device and the management service.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
