    摘要: A remote modular submersible device is suitable for various subsurface operations in a liquid, such as freshwater, salt water, hydrocarbon(s), and/or chemical(s). The remote modular submersible device includes a chassis and a clamping system in the chassis. The clamping system is configured to clamp the chassis to an elongate member. The remote modular submersible device also includes a propulsion system in the chassis. The propulsion system is configured to propel and orient the chassis in a liquid in which the chassis is submerged. The remote modular submersible device additionally includes a processor configured to control at least the propulsion system.

    摘要: An autonomous underwater vehicle includes a vehicle body controlled by a processor. An anchor joined to a tether is disposed in the vehicle. The vehicle has control surfaces for maneuvering, a propulsion unit, and a turbine. The propulsion unit and turbine generate thrust to propel the vehicle. A power source provides power to the vehicle. The turbine is further joined to a generator. When the processor detects that the power source is below a threshold value, the propulsion unit is stopped, the anchor is deployed, and the control surfaces are operated to move the vehicle in a predetermined trajectory through a fluid stream of the environment restrained by the tether. The fluid stream causes rotation of the turbine and generator to recharge the power source.

    摘要: An underwater vehicle for performing a variety of linear motions and turning motions with better stability and agility is disclosed. The underwater vehicle includes a main body, a front-drive mechanism, a rear-drive mechanism, and a steering assembly. The main body has a front end and a rear end, which defines a longitudinal axis extending from the front end to the rear end of the main body. The front-drive mechanism is connected to the main body to provide a forward propelling force in a direction parallel to the longitudinal axis. The steering assembly is fixed to the rear end and coupled to the rear-drive mechanism. The steering assembly is configured to rotate the rear-drive mechanism with respect to the longitudinal axis by a body angle for providing a lateral force on the main body.

    摘要: A deep-ocean polymetallic nodule collector is an apparatus that is used to harvest polymetallic nodules and other natural resources from the ocean floor. To do so, the apparatus includes a support frame and a collection mechanism. The support frame is a durable structure designed to withstand the harsh deep-ocean conditions. The support frame keeps the collection mechanism adjacent to the ocean floor for the mining of polymetallic nodules without damage to the underwater ecosystem. In addition, the support frame allows for attachment of mining support vehicles that support the operation of the apparatus. The mining support vehicles can include, but are not limited to, cabled vehicles which are connected to the surface for power, monitoring, and control, wireless submersible vehicles, or ocean-bottom based vehicles that can operate autonomously, semi-autonomously, or by remote control. The collection mechanism enables the collection of polymetallic nodules while minimizing the damage to the underwater ecosystem.
