CURV III
The CURV III is a 12,600-pound Remotely Operated Vehicle (ROV) that is designed to meet the Navy's deep-water salvage requirements down to a maximum
depth of 20,000 feet of seawater.
The system consists of the vehicle, fiber-optic umbilical cable, motion-compensated handling system, umbilical traction winch and storage reel, deck hydraulic power
unit, generator, operations van, and maintenance van. Navigation can be accomplished by either a long or ultra-short baseline acoustic tracking system. The separate
diesel generator provides electrical power for the system or power from the support platform can be used if it is compatible.
The operator can control the ROV in all six degrees of motion with auto-control functions for depth, altitude, and heading. The vehicle is equipped with CTFM sonar for
target location and has two seven function spatially correspondent manipulators. It has a high resolution digital still camera and black and white and color television cameras.
The fiber optic multi-plex system can combine up to eight channels of video, sonar, and navigation data on a single fiber. A digital communications network with a data capacity of 80 MHz controls the
vehicle and has significant capacity for future expansion. The system is designed to interface easily with additional sensors or tool packages using standard data formats.
For special operations, the ROV can accommodate customized, skid-mounted tool packages. These packages can include, but are not limited to, trenchers, specialized salvage tools, instrument packages
or other mission-oriented equipment.
CURV equipment modules are designed for ground or air shipment, and can operate from any capable vessel of opportunity.
