Survey Ship (redirected from Survey vessel)

Survey Ship 

a vessel designated for investigation on oceans and lakes and rivers. One type of survey ship, the sounding ship, is equipped for studying the topography of the bottom and navigational conditions (currents, landmarks) and for making cartographic and radar surveys of coasts to be used in compiling navigational charts and guides. The equipment of a sounding ship includes devices for studying the topography of the bottom (Fathometers, sonars), instruments for determining coordinates, and hydrological, geological, and geophysical laboratories for evaluating water and ground tests. A second type of survey ship, the buoy ship, sets up and services shore and floating navigational aids, including lighthouses, radio beacons, beacons, radar reflectors and buoys. The buoy ship’s equipment includes apparatus for launching and erecting navigational aids, storage battery re-chargers, gas cylinder replacements, a helicopter landing pad, and equipment for control of the operation of navigational aids. The displacement of a survey ship, depending on its purpose and work location, varies from 1,500 to 2,000 tons. The ships have launches for work in shallow waters.
