Definitions
- the present disclosure relates to a security arrangement for preventing unauthorized boarding of a marine entity, as well as a system, a method, a use, and a marine entity relating to such a security arrangement.
- Boarders conventionally use high speed boats to quickly approach a marine vessel or installation. By using a variety of ladders, climbing poles, grappling hooks, ropes, wires or the like, the boarders may force their way up onboard the marine vessel or installation before the personnel even knows there is an impending threat.
- a preferred solution is using non-lethal force to defend the marine vessel or installation during an attack, for instance by using water cannons, sound cannons, electrical fences, or blinding headlights.
- Other solutions may involve using security bulwarks or concertina razor wire along an exposed perimeter segment of a marine vessel or installation.
- many of these solutions are costly, and are quite ineffective at fending off potential boarders.
- many of these security means may be easily seen from a distance so that potential boarders may take adequate actions to circumvent them. Additionally, many of these solutions are impractical when not in use since they either take up lots of space or are not easily made ready for deployment when needed.
- An example of a security arrangement according to the state of the art is shown in document WO2013/051946 .
- a security arrangement for arrangement to a marine entity.
- the security arrangement comprises a mounting member configured to be mounted to a perimeter segment of a marine entity.
- the security arrangement comprises a first barrier plate arranged to pivot relative the mounting member about a first pivot axle.
- the first barrier plate is arranged to pivot about the first pivot axle between an extended position in which position a front edge of the first barrier plate is displaced transversally from the perimeter segment, and a retracted position in which position the front edge of the first barrier plate is positioned closer to the perimeter segment.
- the security arrangement further comprises a fluid actuator configured to operatively move the first barrier plate between the extended position and the retracted position.
- marine entity it is to be understood as any entity in a marine environment.
- entities may be marine vessels, e.g. any one of merchant ships, cargo ships, naval ships, submarines when at a surface level, or other marine vessels.
- entities may be marine installations, e.g. oil platforms, mining platforms, rocket platforms, or other marine installations.
- such entities may be semi-marine installations, e.g. fortresses, harbors or other defensive and/or strategic locations at least partly located on land and having at least one perimeter segment facing a large body of water.
- perimeter segment it is understood as a predetermined vertical segment of a perimeter structure of a marine entity. In the case of a cargo ship, a perimeter segment may be defined as the segment between two stanchions of a guard rail.
- a perimeter segment may be defined as any other suitable segment of a perimeter of a marine entity.
- security is to be understood as being associated with means or actions for protection against hostile forces.
- safety is to be understood as being associated with protection and/or the continued well-being of personnel and the like.
- the security arrangement may advantageously prevent or at least significantly stall unauthorized boarding of a marine entity.
- boarders may arrange ladders to a perimeter segment in an attempt to climb it to gain access to the marine entity.
- the security arrangement may thus be operated so that the front edge of the security arrangement makes contact with the ladder and pushes it away from the perimeter segment, thereby causing the ladder to lose stability and tumble down.
- boarders may attempt to climb the perimeter segment using ropes, wires or chains or the like. These may be attached to distinct edges at or near the top of a perimeter segment using grappling hooks. Such distinct edges may for instance be provided by guard rails, fish plates, or meshed floor structures.
- the security arrangement may be operated to displace the rope, wire or chain away from the perimeter segment, so that a potential boarder is unable to reach the perimeter segment with their feet, thereby effectively forcing a potential boarder to rely on upper body strength alone to climb the perimeter segment.
- the security arrangement may be resilient and may be configured to not be easily broken by the weight of a potential boarder climbing the rope, wire or the like.
- the fluid actuator may be designed to provide and/or withstand large forces, so that it may securely maintain the first barrier plate in an extended position even if the security arrangement is forced to carry significant weight due to a potential boarder climbing the rope, wire or the like. A secure and reliable security arrangement for preventing, or at least stalling, an unauthorized boarding is therefore achieved.
- a further advantage is that the security arrangement may be safely operated by the personnel on the marine entity. Compared to known security arrangement for marine entities, the present arrangement may provide a low risk of injuries for the personnel on the marine entity when arranging or operating the security arrangement,
- a further advantage is that the security arrangement may be easily removed from and arranged to a perimeter segment.
- a plurality of security arrangements may be easily arranged to form substantially protection along any exposed perimeter segments of a marine entity, even along the entire perimeter of the marine entity if necessary. Depending on geographic area, the security arrangement may only be needed momentarily or for a relatively short duration.
- the security arrangement may be arranged to a perimeter segment on occasion, when needed, and may be removed when not needed.
- the security arrangement may advantageously be transferred to a second marine entity needing the security arrangement when it is determined that a first marine entity no longer is exposed to the threat of unauthorized boarding.
- a further advantage is that the security arrangement may easily be provided to comply with the International Convention for the Safety of Life at Sea (known as SOLAS).
- SOLAS International Convention for the Safety of Life at Sea
- the security arrangement may be embodied in shape and size to comply with SOLAS.
- a further advantage is that the security arrangement may be operated so that the first barrier plate is moved to the retracted position when it is determined that there is no threat of unauthorized boarding. This may advantageously ensure that the security arrangement takes up as little place as possible when not in use.
- the mounting member may be provided with an elongated shape.
- the mounting member may be configured to be mounted to a perimeter segment of a marine entity so that the longitudinal extension of the elongated body of the mounting member is substantially parallel to a common horizontal datum.
- the mounting member may be configured to be mounted to a perimeter segment of a marine entity so that the longitudinal extension of the elongated body of the mounting member is substantially parallel to a common vertical.
- the mounting member may be provided with mounting means for mounting the mounting member to a perimeter segment of a marine entity in either a horizontal or vertical orientation.
- Such mounting means may be through-holes (threaded or non-threaded) arranged to correspond to mounting points located on the perimeter segment of the marine entity, in which screws/bolts may be received to securely mount the security arrangement to the perimeter segment.
- such mounting means may be tether points to which ropes or wires of the marine entity may be attached to securely mount the security arrangement in place at the perimeter segment.
- the security arrangement may be configured so that the first pivot axle extends along the elongated shape of the mounting member.
- the mounting member may be configured to receive the first pivot axle.
- the first barrier plate may be provided with a major plate structure defining an outer surface and an inner surface.
- the inner surface may be configured to be directed towards the perimeter segment when the first barrier plate is in the retracted position.
- the outer surface may be configured to be directed away from the perimeter segment when the first barrier plate is in the retracted position.

- the front edge may be an opposing edge relative the edge/side the first barrier plate is configured to pivot about.
- the front edge of the security arrangement may be a lateral edge of the first barrier plate, preferably a top edge of the first barrier plate.
- the first barrier plate may be provided with a meshed major plate structure or provided with large apertures/through holes within the major plate structure, thereby reducing its weight.
- the first barrier plate may be a pivotable frame, in which a wire mesh or the like is arranged to prevent potential boarders from climbing the perimeter segment through the pivotable frame.
- the fluid actuator may be configured to be fluidly coupled to a fluid reservoir.

- the second longitudinal end of the fluid actuator abuts the perimeter segment and glides along the surface of the perimeter segment when the fluid actuator expands or contracts.
- the portion of the second longitudinal end which abuts the perimeter segment when arranged thereto may be configured in shape, size and/or material to provide a low friction gliding movement along the perimeter segment surface.
- the fluid actuator may comprise a fluidic muscle.
- the fluid actuator may be a fluidic muscle.
- the fluidic muscle may be provided with a major cylinder-shaped body.

- Fig. 7a - 7b illustrates a marine entity according to one embodiment of the invention as it is under threat of potential boarders.
- the marine entity 300 is provided with a security arrangement 1, or a system 100 comprising a security arrangement 1a, 1b.
- the security arrangement 1 is arranged to a perimeter segment 300a of the marine entity 300.
- the first barrier plate 20 is in a retracted position, in which position the security arrangement 1 extends only little in an outward direction from the perimeter segment 300a, thereby making it more difficult to discern from a distance.
- the perimeter segment 300a extends vertically up to the deck, floor, or the like 300b.
- a guard rail 300c is arranged on the deck 300b so as to prevent personnel of the marine entity from falling into the large body of water 500.
- a boat 400 is approaching the marine entity 300.
- two pirates 410a, 410b are positioned, as is illustrated in Fig. 7a . They 410a, 410b are unware of the presence of the security arrangement 1 as it is in the retracted position and not easily seen from a distance.
- One of the pirates 410a throws a rope 420 tethered to a grappling hook 430 up towards the deck 300b.
- the grappling hook 430 attaches to the guard rail, thereby allowing the pirate 410a to climb the rope 420.
- the security arrangement 1 is consequently operated to transversally displace the rope 420 away from the perimeter segment 300a.
- the security arrangement 1 being provided with cutting means 21a is configured to cut the rope 420 when the pirate 410a attempts to climb the rope 420, thereby causing the pirate 410a to fall down into the large body of water 500.
- the cutting means 21a prevents the pirate 410a from climbing over the front edge 21.
- the security arrangement 1 stalls the climbing pirate 410a so that adequate security measurements may be taken by personnel of the marine entity 300.
- the security arrangement 1 may be configured to be positioned at any vertical level at the perimeter segment 300a, preferably closer to the top end of the perimeter segment 300a, which may measure upwards to 10 m or more above the large body of water 500. Consequently, the pirate 410a must climb a considerable distance to gain access to the deck 300b. Moreover, it may further make it considerable more difficult for a pirate 410a to bring heavy equipment, for instance armor or guns, during the climb, as it adds significantly to the weight a pirate 410a must carry.
- the marine entity 300 may be configured with a plurality of security arrangements 1a, 1b, arranged to protect the entire perimeter of the marine entity 300.
- the security arrangement 1, or a system 100 comprising a security arrangement 1a, 1b, sensors 110, 120, 130, 140a, 140b may provide significantly improved defensive capabilities against an unauthorized boarding.
- the invention has been described in relation to marine entities.
- the security arrangement may naturally be applicable to and used for entities wholly located on land having no perimeter segment facing a large body of water.
- the security arrangement 1 may be configured to be coupled to a system for controlling the security arrangement 1.
- the security arrangement 1 may be provided with such a system, and packaged and provided, either separately or as a package.
- the system may be similar to the system 100 previously specified.
