Multiple autonomous underwater vehicles (AUVs) are operated by a single host surface vehicle (HSV) by configuring the AUVs with intermediate nodes (such as unmanned surface vehicles (USVs)) so as to allow the HSV to manage multiple AUVs. The intermediate nodes act as a relay for communications between the HSV and the AUVs allowing the HSV to scale to higher numbers of vehicles thus simultaneously operating the entire fleet of AUVs. The AUVs may provide underwater mapping data.

The present invention relates to a robotic fish that is capable of swimming horizontally and vertically. According to the present invention, the robotic fish includes: a cylinder joint part for performing piston movements to allow the robotic fish to swim under water; and a controller for controlling the cylinder joint part.

The present invention provides an apparatus, method and system for utilizing commercial cargo containers. The present invention utilizes containers made autonomous by coupling a container with a detachable propulsion system, having a motor and navigation and steering controls, permitting the rapid, controlled, efficient and safe delivery of cargo containers individually by water. Ballast units, deployment systems and control via remote units are also disclosed. The containers, utilizing their inherent buoyancy, can move autonomously according to a preplanned or remote controlled route to a specific location.

An autonomous underwater seismic wave generation system includes a housing, and an autonomous navigation system, a propulsion system and a seismic wave generator, each connected to the housing. The autonomous navigation system can navigate the autonomous underwater seismic wave generation system to subsea locations including a location on a seabed. The propulsion system can drive the autonomous underwater seismic wave generation system to the location on the seabed. The seismic wave generator can couple to the location on the seabed to generate seismic waves at the location on the seabed.

There is described a system for deploying and retrieving seismic nodes on the seabed. The system uses a modular container that can be connected to a ROV. The container includes a magazine for storing a number of individual nodes, as well as having means for moving the nodes through the magazine onto the seabed.

An underwater firearm is disclosed. The underwater firearm includes a barrel for receiving an ammunition on a first end and a barrel cap for covering a second end of the barrel. The underwater firearm also includes a capsule having a firing pin and contains a reactive material. The reactive material can be ignited by an electrical ignitor in order to propel the firing pin to strike the ammunition. A housing is utilized to contain the capsule and the electrical ignitor.

A field configurable autonomous vehicle includes modular elements and attachable components. The vehicle can be assembled from these modular elements and components to meet desired mission and performance characteristics without the need to purchase specially designed vehicles for each mission. The vehicle and other autonomous vehicles can be transported to the location of use by a ferry vehicle thereby conserving vehicle systems and resources and expanding the vehicle utility.

The fixing frame has a circular ring configuration in a middle part thereof, and the waterproof sealing cabin is fixed in the circular ring configuration, and multiple cantilever arms extend around the circular ring configuration. An underwater navigation control module and a relay are provided on an auxiliary fixing platform. A second brushless motor is provided on each of the cantilever arms. Each second brushless motor is provided with a marine propeller. A flight control module, a remote control receiver and a power management module are provided on a fixing platform. A first brushless motor is provided on each of the cantilever arms. Each first brushless motor is provided with a rotor via a coupling. The energy supply system is arranged in a lower part of the waterproof sealing cabin.

The present disclosure provides systems, apparatuses, and methods for measuring submerged surfaces. Embodiments include a measurement apparatus including a main frame, a source positioned outside a pipe and connected to the main frame, and a detector positioned outside the pipe at a location diametrically opposite the source and connected to the main frame. The source may transmit a first amount of radiation. The detector may receive a second amount of radiation, determine a composition of the pipe based on the first and second amounts of radiation, and send at least one measurement signal. A control canister positioned on the main frame or on a remotely operated vehicle (ROV) attached to the apparatus may receive the at least one measurement signal from the detector and convey the at least one measurement signal to software located topside.
