A protective wall for use in a structure such as a ship comprises a first and second metal layer, with an armor plate in between and layers of elastomeric material between the armor plate and the first and second metal layer respectively. The first and second metal layer having a higher ductility than the armor plate, the armor plate being mounted between the first and second metal layer in a way that allows the first and second metal layers to stretch relative to armor steel plate at least in response to forces resulting from impact by fragments from an explosion. When an explosion occurs in a space bounded by the protective wall, the first and second metal layer deflect under the pressure pulses due to blasts, stretching relative to the armor plate. The armor plate blocks high speed fragments. The elastomeric material has a double function: it increases the resistance of the armor plate to fragments and it allows for separation of the armor plate from the first and second metal layer, allowing them to stretch.

A hull support structure of a liquefied gas tank has a foundation deck disposed around a liquefied gas tank; a skirt which supports the liquefied gas tank on the foundation deck; an inner bottom plate extending in a hull length direction, at a location that is below the liquefied gas tank; and a pair of bilge hopper plates each of which is provided between the foundation deck and corresponding one of both end portions of the inner bottom plate, wherein a plate connection section at which each of the pair of bilge hopper plates is connected to the foundation deck is disposed outward in a hull width direction, relative to a skirt connection section at which the skirt is connected to the foundation deck.

An internal canoe frame acts as a mount for retractable outriggers, foldable panels, and pontoons. With the outriggers, panels, and pontoons, the canoe can be adapted to provide a stable multi-purpose waterborne platform. In some embodiments, the platform may also include a support frame for a tent, to provide a waterborne camping site for an intrepid canoer.

An input shaft for the torque-transmitting connection of motor and propeller of a ship drive has input-side and output-side interfaces and a composite hollow shaft made of fiber composite material arranged therebetween. The input shaft has a section which is arranged between the input-side and output-side interfaces, is connected to the composite hollow shaft, and is made of non-flammable material. A ship includes a hull, a bulkhead running transversely to the longitudinal axis of the hull, a motor, a propeller and an input shaft described above. The input shaft of the ship is fed through the bulkhead and has the non-flammable section arranged in the region of the feedthrough through the bulkhead.
