Underwater work operations are often restricted by soft bottom materials stirred up by current, moving vehicles, thrusters, tools etc. The turbidity might be so severe that the use of video systems is prevented. Subsea exploration and production of hydrocarbons call for a wide variety of underwater work and inspection activities. As water depths increase as well as the emphasis on diver safety, the remotely operated vehicle (the ROV) plays an increasing role as a “subsea work horse”. ROVs are normally equipped with sonars and video systems as well as navigation sensors, but there is no real-time imaging device covering the work area in case of turbid water.
