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).

An unmanned seismic vessel system can include a hull system configured to provide buoyancy and a storage apparatus configured for storing one or more seismic nodes, each seismic node having at least one seismic sensor configured to acquire seismic data. A deployment system can be configured for deploying the seismic nodes from the storage apparatus to the water column, where the seismic data are responsive to a seismic wavefield, with a controller configured to operate the deployment system so that the seismic nodes are automatically deployed in a seismic array.

Processes and systems described herein are directed to performing marine surveys with marine vibrators that emit orthogonal coded pseudo-random sweeps. In one aspect, coded pseudo-random signals are generated based on coded pseudo-random sequences. The coded pseudo-random sequences are used to activate the marine vibrators in a body of water above a subterranean formation. The activated marine vibrators generate orthogonal coded pseudo-random sweeps. A wavefield emitted from the subterranean formation in response to the orthogonal coded pseudo-random sweeps is detected at receivers located in a body of water. Seismic signals generated by the receivers may be cross-correlated with a signature of one of the orthogonal coded pseudo-random sweeps to obtain seismic data with incoherent residual noise.

An apparatus for generating offshore wind employs shallow draft floats supporting a lattice tower with a wide base having a single-line anchoring providing passive yawing. The lattice structure supports a horizontal shaft at both ends of the shaft for rotating a rotor assembly. Mechanical energy from the rotor may be transferred to electrical generation equipment located at the base of the structure.

This document describes a system for the deployment, towing and recovery of marine equipment from a waterborne carrier, which carrier comprises a hoisting arrangement for lifting the marine equipment into the water. The system cooperates with the hoisting arrangement, and comprises a lateral deployment-recovery assembly for deployment and recovery on a lateral side of the carrier, and includes: a tow winch and an aft lateral outrigger connected to the carrier. The assembly also comprises a tow line guide and a guider winch including a guide line attachable to the tow line guide. The aft outrigger comprises a seat for the tow line guide and a sheave for the guide line to enable guiding of the tow line guide to the seat. The document also describes a method.
