The present disclosure relates to a shock absorbing arrangement suitable e.g. for ship installed structures comprising a rod, a resilient member arranged in connection to the rod, a structure element and a locking member arranged in connection to the structure element. The locking member is arranged to detachably lock the structure element at a resting position at the rod and the locking member, or the structure element, is supported by the resilient member. The resilient member is configured such that a spring force of the resilient member acts to maintain the structure element essentially at the resting position at the rod. The locking member is further configured to release the structure element from the resting position when being exposed to a force exceeding a predetermined holding force, whereupon the resilient member acts to reinstate the locking of the structure element at the resting position at the rod. The present disclosure further relates to a shock absorbing structure comprising such shock absorbing arrangements.

A bulkhead protector apparatus is described. The protector is configured to be mounted within a cavity of the sheetpile of a bulkhead in order to prevent waves, wake, and debris from reaching the top portion of the bulkhead, minimizing damage and prolonging the life of the bulkhead. An angled waterguard portion is disposed within the cavity, and is configured to deflect water down and away from the top of the bulkhead. The waterguard portion is mounted to a whaler of the bulkhead via a planar mount portion which is secured to the underside of the whaler of the bulkhead via stainless steel lag bolts.

A security device is disclosed comprising: a barrier; and a panel, wherein the security device may be transitioned repeatedly between a first configuration and a second configuration, in the first configuration the security device is unassembled and at least the barrier may be arranged in a storage configuration in which the barrier curves or bends through a first angle, and in the second configuration the security device is assembled in an arrangement for use, in which the security device may be assembled around a rail; and wherein, in the second configuration, at least a part of the panel is orientated to be substantially vertical, and the barrier is curved, bent or folded through a second angle, which is greater than the first angle, to protrude away from the panel in a horizontal direction, perpendicular from a plane extending vertically through the rail, to provide an overhang on an exterior side of the rail.

Disclosed is the production of a marine boat with materials that provide bulletproofing and ballistic protection both at the lower hull and the superstructure, or only at the lower hull or only at the superstructure of the boat. The boat is manufactured at a length of 3 meters to 15 meters and has an inflatable tube around it, for use for military and civilian purposes.

A security device comprising: a barrier; and a plate, wherein the barrier and plate are releasably attachable to each other, and when the barrier and plate are attached the device comprises a slot for receiving a rail and the device may hang on a rail with the rail received in the slot, and the barrier protrudes in a horizontal direction, perpendicular from a plane extending downwardly from the rail, to provide an overhang; and wherein at least a portion of the plate is made from a bullet-resistant material.

Structures based upon periodic cellular materials that provide a potential for defeating combinations of both air blast loading and ballistic attack either sequentially or simultaneously, or combination of both. The cellular structures may also be configured to meet the stiffness and strength support requirements of particular vehicle or other applications, systems or structures. The armor is therefore potentially able to support normal service loads and defeat blast and ballistic threats when necessary. The structure provides for using efficient load support capabilities of the material (without a high armor protection level) in low threat conditions, as well as the ability to modify the system to increase its level protection to a desired or required level. This would reduce the weight of the protection system in normal (low threat) conditions which reduces vehicle wear and tear, as well as cost savings in fabrication of applicable structures or systems.

An improved multiple layer hull system may be used in vehicle applications. An upper hull may be monolithic or may have a plurality of seams. A sacrificial lower hull may be entirely U-shaped or partially flat-bottomed, or may have a U-shaped or partially flat-bottomed base with outwardly extending wings complementing a lower surface of the upper hull. A blast deflector may be beneath the lower hull or base either as a separate part or as an integral part.

An armor system pellet is provided. The pellet includes a pellet body attached to four projections for interlocking adjacent pellets when arranged in an array. The pellet is configured such that the width of a first pair of co-linear projections is less than a width of a second pair of co-linear projections.
