Systems and methods are disclosed herein for a modular buoy deployment system including modules arranged to be assembled at a destination location and an aerial delivery apparatus arranged to deliver the buoy modules to the destination location. The modules are connectable to at least one other module and form a buoy when assembled. The module buoy deployment system also optionally includes a platform arranged to receive one or more aerial delivery apparatuses. Each module conforms to a delivery criteria of the aerial delivery apparatus. The module buoy deployment system also optionally includes a power system arranged to recharge the aerial delivery apparatus.

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 marine vessel hull includes an outer hull layer and an inner liner connected to the outer hull layer forming a cavity therebetween. A wireless identification device is contained within the cavity between the outer hull layer and the inner liner. The wireless identification device stores and wirelessly transmits at least one of a vessel identifier, manufacture information, and ownership information for the marine vessel.

A floating structure includes: a floating body including one or more buoyant bodies disposed around a structure; and a plurality of first support wires disposed between the structure and the floating body and configured to transmit the self-weight of the structure to the floating body. Each of the first support wires having: one end connected to the floating body; and another end connected to the structure below the one end.

A measuring device measures a status of a device to be monitored stored within a metal hull of a marine vessel. A first communication device is provided outside the hull and transmits a status signal indicating a measurement value of the status of the device to be monitored. A second communication device receives the status signal via the first communication device and outputs information pertaining to the status. The second communication device is configured to be portable.

The invention relates, among other things, to a component including at least one base plate, at least one cover plate arranged on the base plate, at least one damping layer arranged between the base plate and the cover plate and at least one stiffening element. The base plate is free from the cover plate and the damping layer at least in sections on the cover plate side in a connection area, and the stiffening element is connected to the base plate and the cover plate on the cover plate side in the connection area. The invention further relates to a method for the manufacture of a component and a use of a component.

A frame may comprise a plurality of interlocking tab-and-slot frame members forming a three-dimensional structure. A removable stringer may be designed into one or more of the interlocking tab-and-slot frame members. The stringers may be removed after positioning and welding of tab-and slot frame members together. Notches may also be designed into and formed as additional features of a tab-and-slot frame member. Notches may serve as a guide for bending tab-and-slot frame members and in the creation of tabs and/or slots of the tab-and-slot frame members.
