A method for transporting parcels in an aerial and roadway restricted area comprises an unmanned water transport train (UWTT) utilizing marine unmanned vehicles (MUMVs) receiving and transporting a waterproof tote on a transport waterway. The method can also include a UWTT receiving a waterproof tote from, and/or delivering a waterproof tote to, an aerial unmanned vehicle (AUMV). The method can include adding one or more MUMVs to the UWTT, and/or replacing a failing MUMV with one or more substitute MUMVs. An unmanned water transport system (UWTS) comprises a UWTT that includes MUMVs and waterproof totes. The UWTT is configured to transport the totes on a transport waterway. An MUMV can include a tether and a tote can attach to the tether. The UWTS can include a control center and/or AUMVs, and the UWTT can receive a tote from, or deliver a tote to, an AUMV, and/or receive additional MUMV(s).

Systems and processes for transferring a gas from a buoy. In one embodiment, the system can include a buoy floating in water. A fluid swivel assembly can be coupled to the buoy. The system can also include a gas submarine conduit and a pipeline end manifold located at a subsea location. The gas submarine conduit can be configured to transfer a gas between the fluid swivel assembly and the pipeline end manifold. The gas submarine conduit can include one or more negatively buoyant members coupled thereto. The one or more negatively buoyant members coupled to the gas submarine conduit can urge the gas submarine conduit toward a seafloor to maintain the gas submarine conduit in a Chinese lantern configuration.
