12 aspects (not always considered) that will improve the safety of your fairway or channel. Episode 2.
As I pointed last week, the correct design of fairways and channels regarding the use of AtoNs, it is a process, that must consider among other aspects, the needs and perspectives who will use them, to diminish the potential occurrence of accidents and/or maritime disasters, with loss of human lives, damage to the environment and their assets.
These are the next 4 aspects that IALA deemed should be considered during the design of fairways and channels, regarding the use of AtoN. (The last 4 aspects will be considered in my next post).
- In the design of a fairway / channel, and where a split is required (e.g., a preferred channel) the following conditions should be taken into consideration: existence of a traffic separation scheme, preferred channel marking, incoming traffic from a different channel with mandatory obligations (to choose one direction) and fairways Intersect.
- In a fairway/channel with limited width, consideration should be taken that floating AtoN positions might be subjected to variations (swinging circle) because of depth, tides, current and mooring types. So, special attention should be given to the mooring system and to the type of buoy you will use to keep AtoN´s sufficiently accurate position and not reduce the width of the fairway/channel.
- The design of the fairway/channel should ensure ship’s safe maneuvering and assess the navigational risk to improve the safety of ship underway, according to IMO International Regulations for Preventing Collisions at Sea 1972 (known as COLREGS).
- If the conditions of the area include limited visibility (e.g., 10 days of visibility under 1 Nautical Mile per year) installation of an audible, or sound signal may be justified and considered.
Unfortunately (or fortunately), there is no single recipe that can be applied to this type of process, but there is no doubt that at least these 12 considerations I will point out and considered by IALA, will allow you to increase the safety standards during the design of fairways and channels -regarding the use of AtoN- that will help you to prevent the occurrence of maritime accidents, damage to the environment and protect your assets.
Stay tuned for the last 4.
