kelluvuuskorkeus

Kelluvuuskorkeus, often translated as buoyancy height or freeboard, is a concept used in naval architecture and maritime safety. It refers to the vertical distance between the waterline of a vessel and the main deck or the lowest continuous watertight deck that extends from side to side. This height is crucial for ensuring a ship's stability and its ability to withstand the ingress of water.

A sufficient kelluvuuskorkeus is essential to prevent water from coming over the deck, especially in adverse weather conditions. If the kelluvuuskorkeus is too low, waves can easily wash over the deck, potentially flooding compartments and compromising the vessel's integrity and stability. Conversely, an excessively high kelluvuuskorkeus might not be practical or economical, impacting cargo capacity or stability characteristics in certain designs.

Regulations set by classification societies and maritime authorities specify minimum requirements for kelluvuuskorkeus based on the type, size, and intended service of a vessel. These requirements are designed to provide an adequate margin of safety against various maritime hazards. Designers meticulously calculate and incorporate the appropriate kelluvuuskorkeus into their plans, considering factors like wave action, cargo loading, and the vessel's structural design. It is a fundamental parameter in the overall safety and seaworthiness of any ship.
