Preparation for Transiting Piracy Area-HRA

Anti-Piracy Precaution

Vessels can avoid or delay an act of piracy and greatly increase the chance of Naval Force intervention by taking a number of relatively simple preparatory steps. Careful preparations by the ship may deter the pirates from attacking if their closer inspection of the potential target reveals a number of protection measures.

Analysis of successful attacks indicate that the most common vulnerabilities exploited by the pirates  are low speed (to date no successful attacks have occurred on ships at 18 knots or more) and low freeboard (less than 8 mtrs).

Once onboard the vessel, they usually try to make for the bridge to enable them take control of the vessel. Preventing access to the bridge can significantly improve safety or delay an attack by constructions of barriers.

The construction of barriers and the anti-piracy equipment required on board a vessel shall depend on the ship design.

dating agency london  Razor  wires  are  very  sharp  and  must  be  handled  very carefully,  especially as ship’s crew does not routinely handle razor or similar sharp wires. Strict safety precautions must be taken while transporting, storing, handling and deploying razor wires.  Required PPE including Helmet with Visor, heavy duty rigger gloves with protective palm and finger pads worn over cotton gloves must be use

 Razor wires are supplied pre-coiled. Coils are generally supplied packed with protecting plastic wrapping covers which should be removed at the locations prior stretching it on ship's side railings. Adjacent coils are usually factory tagged to each other with clips.

 While rigging / unrigging razor wire, following safety precautions to be taken:


 -      Ensure all PPE is in use.

-      Unwrapping the razor wire from its protective plastic covers is to be done slowly and methodically. Cut wire ties and unwrap, do not cut the packaging away.

-      Slowly pry the razor wire apart while gently shaking either end of the wire. This will allow the razor wire roll to unravel.

-      The effectiveness of the razor wire is reduced if it is stretched too much. Also, the coil of razor  wires may lose its shape if it stretched too much and it is time consuming and difficult to bring it back to its original shape.

-      Rigging: At-least four (4) persons should handle the coil at all times so that it is uncoiled in a  correct manner, one layer at a time. While two persons are required to carefully spread it over the side along the railing, others are required to secure the alternate coils with seizing wire on to the railing.


march-maintainence-002 march-maintainence-001


-      When fixing the razor wire to the railing, DO NOT over tighten the razor coil. This makes

the construction sparse and easier to climb. The fence must remain slightly loose.


 -      Individually cut the seizing wire used to secure the razor wire. Do not cut the razor wire.

-      At least four persons (4) are required while unrigging. Two persons to hold the razor wire while others cut and remove the seizing wires. Each coil must be collected on to the previous coil as it comes off from the side railings.

-      Beware of springing effect as the razor wire becomes loose.

-      DO ensure that as each length of razor coil is removed, it is recoiled. The two persons on either  end to slowly walk towards each other closing the razor coil. The persons standing in the middle are to gather it in and ensure it closes methodically and safely.

-      Incase two layers of razor wire  were installed; do remove the top layer completely before starting the lower layer of razor wire.

-      Once the coil is gathered back to its packaged state, tie it off in three areas evenly to secure the coil.

-      When securing the coils, where possible, the coils should be palletized and strapped.


 Safety Precaution while Rigging Razor Wire

The  installation of razor  wire  when  passing  the Gulf  of Aden  and  the  Indian Ocean  has introduced  some new hazards during installation and removal. For the last six months we estimate that every day 2 managed ships will be engaged in either rigging or removing razor wire. This is a job that our crews have become quite familiar with, but we hope it is not a case of them becoming more casual or less careful.

  Manufacturer’s guidance for installing Razor Wire

The straining wire should be set out first then the reinforcing wire set around the vessel on the lower edge of the deck.

  • Then a coil of razor wire should be taken over the straining wire, with the surplus wire proceeding first & the razor wire being placed & clipped in position

  • This is a three-man operation 1 controlling the razor wire coil, 1 placing the wire and the third man clipping in the razor wire.

  • Clips should be placed at intervals of at least one meter

Basic safety for Razor Wire

  • Rolls of Razor wire to be carried, not dragged along the deck

Use rope tails on the coils to reduce direct handling of the wire

  • Open each coil and remove individually. Force should not be used to separate the coils.

  • Fit the coil to the top of the straining wire first - Do not stretch the coil.

  • Clip the coil onto the straining wire from top to bottom.

  • An adjoining the Coil should not be fitted to the straining wires until the first sheet is completely fixed to the straining wires.

  • Be careful when handling this product is sharp and designed to cut your skin.

  • Be careful of the wire elasticity it can spring back without warning

  • Follow standard safety procedure risk assessment and tool box talk before starting work.

  • PPE must be worn at all times when handling razor wire

 PPE to be worn while installing / removing Razor Wire

  • Safety shoes, Boiler suit, Helmet with visor.

  • Thick leather gloves (five finger welding gloves are used on some of our ships and are more than adequate for this job), leather apron with sleeves and long spats / leggings.

  • If you are rigging razor wire overboard or if you are working on or over the ships railing, then a safety harness and / or inflatable lifejacket is required (Permit to be used)

  • If you are rigging razor wire above deck level or in the vicinity of head / face then eye protection should also be used.

  Please  note  that  it  is  required  / recommended that heavy  duty riggers gloves with protective leather or armored palm and finger pads which offer wrist protection must be worn when handling razor wire.



How Does Night Vision Work?

 Night vision devices gather existing ambient light (starlight, moonlight or infra-red light) through the front objective lens. This light, which is made up of photons goes into a photocathode tube that changes the  photons to electrons. The electrons are then amplified to a much greater number through an electrical and chemical process. The electrons are then hurled against a phosphorus screen that changes the  amplified electrons back into visible light that you see through the eyepiece (ocular lens). The image  will now be a clear green-hued amplified re-creation of the scene you were observing.

 An  NVG  phosphor  screen  is  purposefully  colored  green  because  the  human  eye  can differentiate more shades of green than other phosphor colors.

 What do terms Gen 1, Gen 2, and Gen 3 mean?

 Gen. is an abbreviation for "Generation". Night Vision devices of all generations are evaluated by two commonly used measures:

 Light gain: measures how many times a night vision unit can amplify the available light.

 Resolution: measures how sharp and clear the amplified image will appear. (Resolution is defined in line pairs per millimeter or lp/mm).

 A Night Vision Device can be a 1st, 2nd, or 3rd generation unit. What this stands for is what type of light intensifier tube is used for that particular device. The light intensifier tube is the heart and soul of an NVD.

 1st generation Gen 1 equipment was originally developed in the 1960s primarily for military applications. Gen 1 night vision equipment is build around image intensifier tubes with very simple  configurations. Gen 1 image tube is vacuum-sealed and consists of a photocathode and a phosphor screen. Utilizing the basic principles, a 1st generation will amplify the existing light several thousand times letting you clearly see in the dark. You may notice a slight nigh- pitched whine when the unit is on. The image you see may be slightly blurry around the edges. This is known as Geometric Distortion. When you turn a 1st gen off it may glow green for some time. These are inherent characteristics of a 1st gen and are normal.

 2nd generation Gen 2 equipment was developed through the 1980s, and differ from Gen 1 with  different tube engineering. Gen 2 equipment is enhanced by utilizing a micro-channel plate (MCP). MCP boosts light gain of an image tube by about 1000 times. As a result the output image is brighter  and clearer. Gen 2 equipment is costly and fits the needs of more advanced users. This extra process allows 2nd generation units to amplify the light many more times then 1st generation giving you a brighter and sharper image.

 3rd generation is the latest in night vision technology. These devices are used by the armed forces  and  its sale  is controlled. By adding a  sensitive chemical, gallium arsenide to the photocatnode a  brighter and sharper image was  achieved.  Gen 3 equipment shows best results when used in poorly lit environments such as in canyons, forests or jungles.

 Among the most common questions about night vision equipment, are questions about the dissimilarities in the 3 generations of night vision. Naturally the price increases from Gen 1 to Gen 2,  and from Gen 2 to Gen 3, but the benefits do too. On a spectrum of 0-100%, zero comparing to unaided human eyesight and 100 being roughly equal to normal daytime viewing abilities, each generation offers its own unique range of intensified night vision abilities. Visual abilities of Generation 1 range from 10-20%, Generation 2 from fifty to sixty percent, and Gen3 from 75-85%.

 Similarly,  operational  endurance  increases  with  each  of  these  gens.  Operational  life  of Generation 1 devices is typically 500-1,000 hours, while Gen 2 provides two thousand hours, and this figure grows to ten thousand for Gen 3 devices.


Night Vision  Gen 3 Binoculars


How Far Can You See With A Night Vision Device?

 There are many different variables that can affect the distance that you can see with a Night Vision device. First, what are you trying to see? Are you looking for another boat on the water or are you  looking for a rabbit in the woods? The larger the object is the easier it is to see. Secondly, are you trying to see details (what is called recognition range) or are you just trying to see  if something  is  there?  Maybe  you  will  see  some  movement  but  won't  be  able  to determine exactly who or what it is. This is called detection range. Another variable is lighting conditions. The more ambient light you have (starlight, moonlight, infrared light) the better and further you will be able to see. You can always see further on a night when the moon and stars are out then if it is cloudy and  overcast.  We typically state that you can tell the difference between a male and a female or a dog and a deer at about 75 to 100 yards. However, if you were looking across an open field and there was a half moon out you could see a barn or a house 500 yards away. Remember, that the purpose of  an  NVD is to see in the dark not necessarily a long ways like a binocular.

 Therefore the effective viewing range of a Night Vision Device varies anywhere from 300 to 1500 feet. The viewing distance depends on the area, conditions and a size of your target. Overcast conditions, rain and snow will significantly reduce the effective viewing range. On the other hand your viewing range will increase dramatically under clear skies and/or full moon. Light reflective surfaces such as sea will also increase the effective viewing range of your night vision device. Infrared illuminator (IR) may help, especially in enclosed environments.

 What are precautions to using Night Vision?

 - The NVD should not be turned on in day light

- The NVD should not be aimed at bright light (even in the dark)

- The NVD should not be disassembled without professional assistance

- Try not to drop or shake the NVD

- The objective lens of the NVD should not be touched (touch it only with soft non-abrasive cloth)

- It is better to keep the device in a case, in order not to damage it.

 Can a Night Vision device and/or Infrared Illuminator be harmful?

 Night Vision technology is absolutely harmless. It does not emit any type of radiation nor will it blind you if a bright light hits it while in use. Most likely it will damage the device. Night vision is no more dangerous or harmful than watching TV. Diode (LED) based IR Illuminators are also harmless. Laser based  illuminators on the other hand, CAN be harmful to your eyes. If you have a laser based IR use it with caution. Laser based IRs seldom appear on the consumer market.
