zweefdiepte
Zweefdiepte is a term used in underwater technology and marine research to describe the depth at which an object can maintain a stable hover in the water column without continuous propulsion. In practice, it is the depth where buoyant force equals the object's weight, resulting in neutral buoyancy. Because seawater density changes with depth due to variations in temperature, salinity, and pressure, the corresponding zweefdiepte depends on both the object's density and its ballast or buoyancy system.
Calculation and control rely on Archimedes' principle: neutral buoyancy occurs when the density of the object
Applications include autonomous underwater vehicles, remotely operated vehicles, and scientific sensors, where maintaining a fixed zweefdiepte
Several factors influence zweefdiepte: local water density profiles, which change with depth and conditions; the design
The term combines zweven (to hover) and diepte (depth) and is commonly used in Dutch marine engineering
