CURV-21 is a 6,400-pound Remotely Operated Vehicle (ROV) that is designed to meet the US Navy's deep ocean salvage requirements down to a maximum depth of 20,000 feet of seawater. This vehicle is loaded with a host of new technologies and was built as a direct replacement for CURV-III but with a smaller overall system footprint.
CURV-is capable of being deployed on a USNS T-ATF. The system is based on a .680 fiber-optic umbilical cable and a shared handling system that can switch at sea between side-scan sonar and ROV operations. The system is self-contained and flyaway transportable for worldwide response on vessels of opportunity.
The ROV can be controlled in all six degrees of motion with auto-control functions for depth, altitude, and heading. An integrated DVL allows 1 and The 2 meter incremental movements as well as cruise control for extended axial movements. The vehicle is equipped with CTFM sonar for target location and pinger detection. The ROV uses two seven function rate manipulators. It has a high resolution digital still camera, black and white, and color television cameras. The system includes a load bearing, pressure compensated, Electro-Optical Umbilical Swivel.
The fiber optic multiplex system can combine up to eight channels of video, sonar, USBL, RS-232/422/485 data communications, and navigation data on a single fiber. 2 spare fibers are available subsea for additional sensors. A digital communications network with a data capacity of 400 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 tool packages. These packages can include, but are not limited to specialized salvage tools, instrument packages, or other mission-oriented equipment.
