7.1. PERIODICITY
The life of any equipment (buoy, beacon, etc..) depends on local operating conditions, i.e.:
location, sea conditions in the area, water depth, sea-bed type, presence of abrasive particles
into the water, current speed, exposure to boat traffic, etc.. The faster wearing will occur in
offshore areas exposed to harsh sea or areas with a higher risk of impacts with boats when
marking a narrow zone of passage.
A plan for revision and replacement of wearing elements to maintain a safe operation has to be
implemented. Besides, historical information must be kept to forecast buoys or lanterns life in
specific locations.
The recommended maintenance tasks for each type of equipment are listed below:
