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 module for buoyancy control.

Disclosed is a device for connecting two parts of a ship hull, including: a first frame intended to be integral with a first part of the hull; a second frame intended to be integral with a second part of the hull; a tenon integral with the first frame; a mortise arranged in the second frame and able to receive the tenon as a result of a relative translation of the two frames towards each other in a longitudinal direction of insertion; and a pin which is able to be engaged, on the one hand, into a transverse housing provided in the second frame and opening into the mortise and, on the other hand, into a transverse through-hole provided in the tenon, so as to hold the tenon in the mortise. Also disclosed is a hull of a ship including such a device.

A modular barge includes a first barge section and a section barge section. The first barge section is buoyant in water, and includes a first locking mechanism. The second barge section is buoyant in water, and includes a second locking mechanism. The second locking mechanism is attached to the second barge and includes a protrusion configured to couple to the first locking mechanism.

A submersible system is provided having a submersible launch vessel that sends instructions from a mission controller to deploy one or more deployable systems for one or more underwater operations. The submersible launch vessel is submerged within a waterbody. A submersible power supply powers the submersible launch vessel and the one or more deployable systems. One or more communication devices is in communication with the mission controller, and the mission controller is located in one of a remote or a local location relative to the submersible launch vessel. The one or more deployable systems, via the one or more communication devices coupled to the submersible launch vessel, are remote controlled by the mission controller to execute the one or more underwater operations. Also, information associated with the one or more underwater operations including telemetry data is transmitted to the mission controller from the submersible launch vessel.

A watercraft includes a deck, a hull supporting the deck, and a barrier structure. The barrier structure includes: a frame connected to at least one of the deck and the hull and at least partially surrounding a portion of the deck; and a pliable sheet wall connected to the frame. The frame includes an upper portion including a rail for grabbing by a user's hand; and a lower portion connected to the at least one of the deck and the hull. The lower portion and the upper portion are connected to one another. The pliable sheet wall is stretched across at least a portion of the frame so as to extend between the upper and lower portions of the frame. A barrier structure is also contemplated.

Water craft comprising a hull, with an opening and a lowerable segment arranged in said opening. The lowerable segment is coupled to the hull via a lifting mechanism for lowering or raising the lowerable segment with respect to the hull between a first position in which an outer surface of a bottom wall of the segment is substantially flush with the outer surface of a bottom of the hull adjacent to the segment, and a second position wherein the segment is arranged below the water line of the hull. The lowerable segment comprises a lower watertight compartment and an upper compartment that can at least partially be filled with water when the segment is lowered and can be drained when the segment is raised. When in the first position, a wall between the lower and upper compartment is arranged at a level at or near the water line.

The present invention is directed to an inflatable and floatable modular platform system wherein certain embodiments comprise an adjustable back-rest. The inflatable platform system of the present disclosure includes floating elements of differing shapes and sizes configured to be interconnected in order to allow users to stand, sit, and walk between floating elements. Embodiments include inflatable platforms having circular, arc-shaped, rectangular, and L-shaped inflatable platforms.
