The invention relates to the field of special purpose robotic systems to conduct external functions such as cleaning, monitoring and inspection of structures such as tubular assets in a splash zone. The splash zone is defined as the section of a marine structure that is periodically in and out of water due to the action of waves or tides, usually falling within (+)10m to (−)20m water depth. In embodiments, splash zone inspection robot system 1 comprises station 300, submersible saddle 350, submersible robot 400, and subsea robot controller 308. A predetermined set of controllable clamps selectively secure submersible robot 400 to submersible saddle 350 or structure 2 and allow incremental traversal along submersible saddle 350 or structure 2.

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 can include a mechanisms that magnetically attach and release payloads such as cargo or ballast from the vehicle.

A catamaran lifting apparatus is disclosed for lifting objects in a marine environment. The apparatus includes first and second vessels that are spaced apart during use. A first frame spans between the vessels. A second frame spans between the vessels. The frames are spaced apart and connected to the vessels in a configuration that spaces the vessels apart. The first frame connects to the first vessel with a universal joint and to the second vessel with a hinged connection. The second frame connects to the second vessel with a universal joint and to the first vessel with a hinged or pinned connection. Each of the frames provides a space under the frame and in between the barges that enables a package to be lifted and/or a marine vessel to be positioned in between the barges and under the frames. In this fashion, an object that has been salvaged from the seabed can be placed upon the marine vessel that is positioned in between the barges and under the frames.

A system for creating additional storage on a marine vehicle is provided. The system of the present disclosure is generally designed to secure to a marine vehicle via a rod holder, wherein parallel bars provide additional storage area for marine equipment, such as innertubes. To this end, the system of the present disclosure may comprise supports and support braces. Straps may be used to attach the marine equipment to the supports. To ensure that the supports are properly secured within the rod holders, a sleeve may be used to increase friction and change size. Board arms may be attached to the supports in order to increase storage area.

A motorized water sports equipment rack and method for motorized swiveling of a water sports equipment rack attached to a boat are disclosed. The motorized water sports equipment rack includes a mounting bracket for securing the mounting bracket to the boat and a water sports rack mounting bolt connected to the mounting bracket. A swivel bracket is connected to the water sports rack mounting bolt. A water sports equipment rack mount is connected to the swivel bracket. The water sports equipment rack mount supports a water sports equipment rack adapted for holding various types of water sporting equipment. A sealed actuator housing is connected to the swivel bracket and houses an actuator, such as an electric, pneumatic or hydraulic actuator. The actuator is configured to drive the swivel bracket to rotate the water sports equipment rack.

This disclosure relates generally to waste collection, storage, and retrieval from water. Aspects of this disclosure relate to submersible cleaning vehicles, filter systems, ships, communication systems, autonomous navigation, and computer systems. The submersible cleaning vehicle can navigate underwater to capture waste in filters. Abase station can support the submersible cleaning vehicle.

A water-propelled or water-powered unmanned aerial vehicle including a base configured to carry a payload, and at least one nozzle attached thereto. The at least one nozzle is configured to selectively receive pressurized fluid from a source located remotely from the vehicle. The vehicle includes a control system configured to alter or otherwise selectively dictate the flow of fluid through the at least one nozzle and/or the orientation of the at least one nozzle with respect to the base in response to a received control signal for providing controlled unmanned vehicle flight.

A securing assembly is adapted to secure objects to a structure. The assembly includes an attachment mechanism adapted to attach the assembly to an object in use. An elongate rod has a first end and a second end, wherein the first end is connectable to the attachment mechanism and the second end is connectable to an adjustment device. A base is adapted to connect the adjustment device to the structure in use. The adjustment device is operable to adjust a tension between the object and the structure by way of the assembly to secure the object to the structure in use.

A submarine vehicle may include a storage area for storing loads. The submarine vehicle may further include a pressure hull. The submarine vehicle is configured to pick loads up from a seabed and/or set loads down on the seabed. The storage area may be positioned outside the pressure hull and, in some examples, between numerous pressure hulls. Further, the storage area may include a lower hatch disposed on an underside of the pressure hull or an upper hatch disposed on a top side of the pressure hull. Some submarine vehicles may include a load transporting system for picking the load up from the seabed, setting the load down on the seabed, and/or conveying the load within the storage area.
