Hydrographic survey vessel


A vessel equipped with hydrographic survey equipment to determine underwater topography in order to produce high-precision charts. This shows that, among other things, it has to be able to measure water depth (soundings), to scan the seabed in order to locate wrecks and other underwater obstacles, and verify the exact position of buoys and other markers. To enable the vessel to perform its tasks in shallow waters, it is equipped with survey launches, acting as “daughter-vessel”, collecting data needed on the mother ship.
