| Even with modern navigation technology, ship collisions and powered groundings are not uncommon and still represent more than 28% of all larger maritime accidents. The reason for these accidents are almost always human errors that can be traced back to multi-factor situations such as long working hours, multiple alarms and challenging traffic situations. The consequences of collisions and groundings range from injuries or death, to high repair cost, costly idle times and sometimes to disastrous environmental pollutions. | ||

Inspiration from the aviation industry:
The central idea behind the 3-dimensional Attention Zone (3dAZ) concept is quite similar to the solution developed for the aviation industry. We suggest that automated or semi-automated zones are assigned around various maritime objects and displayed in ECS/ECDIS charts. This would help the navigator to focus his attention to potentially critical situations where zones start to overlap. |

Attention Zone
The size of an Attention Zone shall reflect the object’s associated risk. Objects with a higher risk potential automatically get larger attention zones. Touching or overlapping zones, or zones of severe weather call for the attention of the navigator or VTS controller. Land-based authorities, e.g. VTS’s, may often have additional information about risks, such as those posed by a congested traffic situation, other vessels, cargo types, sandbanks, or of near coastal activities such as a regatta or a floating object which could easily be incorporated by adjusting the zone sizes. |
