IALA BUOYAGE SYSTEM 12

[Audio] IALA BUOYAGE SYSTEM an Over view CIFNET Centre for Deep Sea Fishery Training.

[Audio] Introduction The expanded form of IALA is INTERNATIONAL ASSOCIATION OF MARINE AIDS TO NAVIGATION AND LIGHTHOUSE AUTHORITIES. It is a non-profit international technical society established in 1957 to combine representatives from producers, consultants, research and training institutes, and authorities responsible for marine aids to navigation from all parts of the world. The organization aims to standardize marine navigation aids throughout the world for safe, efficient, and generally understood navigation for all people. Different buoyage system means different rules, in complete conflict with one another. It would cause confusion and lead to accidents. The development of a uniform system of buoyage throughout the world was of paramount importance for Safe navigation at sea. CIFNET Centre for Deep Sea Fishery Training.

[Audio] For the sake of maintaining uniformity in buoyage system worldwide, IALA divided the world into two regions Region A and Region B. REGION – A - Red to port Region A –Follows Europe, Australia, New Zealand, Africa, the Gulf and some Asian countries REGION –B - Red to Starboard Region B - Follows North, South, Central America, Japan, Korea and Philippines. Only lateral and preferred channel marks differ between the two regions. All other types of navigational marks are identical worldwide CIFNET Centre for Deep Sea Fishery Training.

[Audio] LATERAL MARKS Lateral marks indicate the Starboard or Port Side of the channel or fairway. They indicate which side of the channel, the vessel should move. The Port Lateral marks should be kept on the Port Side (Left) side of the vessel, while the Starboard Lateral Marks should be kept on the Starboard side of the vessel (right) when it is approaching the harbour.

[Audio] Preferred Channel Marks in IALA Buoyage System These are a special type of lateral marks. They are present to indicate a preferable or recommended channel when the waterway splits into two. The primary purpose of a preferred channel mark is to guide mariners take the better and safer way to reach their destination and hence, increase overall safety. As in the case of other lateral marks, their colour and the lights vary in Regions A and B. It has a primary colour and a stripe. The primary colour indicates the side of the main channel to be followed and the stripe indicates that there is an alternative channel to the other side, which is preferable.

[Audio] SAFE WATER MARKS There is navigable water around a safe water mark in the IALA Buoyage System. It usually marks the middle of a channel or passage going towards a harbour. They also guide a vessel to a safe zone or area, especially where there are rushing and complicated waterways.

[Audio] ISOALTED DANGER MARKS An isolated danger mark indicates a hazard to navigation with safe water all around it. This mark specifically warns mariners of a single danger such as a rock, wreck, or shoal that can be safely navigated around.

[Audio] SPECIAL MARKS A special mark in the IALA Buoyage System is used to indicate special information or an allocated area, such as a fishing zone, anchorage, or controlled area. Special Marks are basically information-providing marks and do not indicate dangerous and safe navigation areas. They assist mariners in locating these specific areas and carry out respective local regulations. Feature Description Color Yellow Shape Conical, Spar, Cylindrical, Pillar, Spherical Top-mark Yellow Cross on it's side Light Yellow Rhythm Any rhythm except those used by other buoys CIFNET Centre for Deep Sea Fishery Training.

[Audio] CARDINAL MARKS The word 'Cardinal' refers to the directions on a navigational compass. Cardinal Marks in the IALA Buoyage system indicate cardinal directions of underwater hazards and obstructions. They essentially mark the cardinal extent of safe water, that is which side is the safest side to pass an underwater hazard. As the name suggests, there are 4 types of Cardinal Marks CIFNET Centre for Deep Sea Fishery Training.
