UNDER-KEEL INSPECTION SYSTEM

摘要

An under-keel inspection system (10) for inspection of vessels (20), e.g. underway toward or away from a harbour or other protected anchorage, comprises a beam (14) configured for being arranged across a navigation corridor (18) at a depth sufficient to allow a vessel to pass above the beam during inspection. The beam has a plurality of individual hull inspection devices (12) mounted thereon, which are distributed over the length of the beam. Each hull inspection device is equipped, at least, with a sonar (24) and is coupled with a deployment mechanism that may individually raise and lower the hull inspection device perpendicular to the axis of the beam in such a way as to adjust the distance between the hull inspection device and the vessel to inspect.
