passeringsnivåer
Passeringsnivåer, or passage levels, refers to the designated depths or heights at which vessels are permitted to navigate through bodies of water, particularly in channels, straits, or areas with restricted drafts. These levels are crucial for ensuring safe navigation, preventing groundings, and managing maritime traffic. They are typically determined by factors such as the natural or artificially maintained depth of the waterway, tidal conditions, and the maximum draft of vessels operating in the area.
In many cases, the minimum passable depth is established by hydrographic surveys and is regularly monitored.
The concept of "passeringsnivåer" also extends to bridges or overhead structures. In such instances, the clearance
