How Safe Is Safe Enough?
Addressing all aspects of safety while working in a water environment is beyond the scope of this documentation. VideoRay
encourages you to participate in safety training appropriate for your industry and applications, including such topics as vessel
operations, first aid, survival and other relevant topics.
Introduction to the System Components
Unpack the system and familiarize yourself with the components.
ROV System
The base system for a CoPilot RI configuration includes the VideoRay Pro 4. For more information about the VideoRay Pro 4,
see the VideoRay Pro 4 Operator's Manual.
BlueView Imaging Sonar
Forward looking imaging sonar provides extended visual range capabilities. Possible targets of interest can be observed and
marked, and the system can navigate to them manually or automatically.
Teledyne RDI DVL (Doppler Velocity Logger)
The DVL is used to keep track of the vehicle's location while it is underwater. It uses an array of acoustic beams to track its
course over the seafloor in a local coordinate system.
ROV GPS Antenna
The ROV GPS Antenna provides a method to identify the vehicle's location within a global reference frame. GPS is not effective
underwater, so the GPS Antenna only works when the ROV is on the surface. Periodic GPS fixes can supplement the DVL
tracking.
Some items shown are optional and not included with all models.
Additional Items
Additional items may be supplied with your system including tools, spare parts and other items. If included, these items are described
in other sections of this documentation.
Some items shown may be optional and not included with your configuration.
PreDive Preparations
Select a safe and preferably level area to set up the control panel. See the Onsite Operations section of the Project Management
Guide for more information about site selection and set up.
The predive preparations consist of three parts, a visual inspection before setting up the system, setting up the system including
making connections, and power on tests of the system's safety circuits and primary functions.
Conduct a Visual Inspection
Assuming this is your first time using the VideoRay, everything should be in proper working order and ready to go, but it is good
practice to perform a predive inspection before every dive, even your first. If any problems are noticed, refer to the Diagnostics and
Repair section of the Maintenance Guide and take appropriate corrective action, or contact VideoRay for assistance before
commencing the dive.
1. Inspect the ROV and other system components to make sure there are no visible signs of damage or loose or warn parts. Also
check for water inside the ROV hull by holding it with the front facing downward and look for signs of water in the main dome
or light domes.
2. Check the horizontal thrusters to make sure that the shafts are not bent and the propellers are free to spin and are not fouled,
loose or binding on the thruster guards. Check the thruster cartridge seals they are filled with oil and there should be no
signs of leaking or contamination. A small air bubble in a thruster cartridge seal is acceptable. See the Maintenance Guide for
warnings, replacement criteria, examples and replacement procedures.
3. Check the vertical thruster to make sure the shaft is not bent and the propeller is not fouled or loose or binding on the float
