Specifications include, but are not limited to: Contractor will deliver a remotely operated vehicle and necessary control equipment (umbilical and control console) with the following minimum specifications: ROV body and performance: • Depth rating minimum 300 m seawater; • Vehicle weight maximum 400 lb. in air; • Vehicle weight minimum 100 lb. in air, to enable stable, linear, near-bottom transects while resisting wave surge in 15 – 70 m depths in open-ocean wave-exposed environments with all payloads described below; • Sufficient forward thrust to maintain seafloor transects at speeds up to 1 knot with the vehicle pulling its umbilical in ocean currents and depths to 70 m (generally expected to be > 100 lb. forward thrust); • Thrusters designed to allow lateral movement, either with vectored thrusters or dedicated lateral thrusters; • Sufficient vertical thrust for the vehicle to rapidly ascend/descend with all payloads described below (generally expected to be > 75 lb. vertical thrust ); Umbilical and control equipment: • An umbilical cable with copper conductors (not fiber optic) sufficient to conduct seafloor transects in 300 m depths (maximum 400 m cable length); • An ROV control console with joysticks and inputs (dials/switches) for adjusting ROV position, speed, and heading. Console should preferably also include controls for lights, lasers, camera tilt, and other peripherals, although these may be controlled by a separate keyboard; • Any necessary power supply transformer to operate the vehicle on 240 VAC power supplied by a marine vessel generator; Vehicle sensors, data display, and control: • A depth sensor delivering real-time ROV depth data for logging and display; • An electronic compass delivering real-time ROV heading data for logging and display; • Pitch and roll sensors delivering real-time ROV pitch and roll data for logging and display; • On-screen display software (displaying on a computer and monitor owned by ODFW, not included in purchase), to include compass heading, pitch, roll, and depth real-time data displays overlaying a video feed from the ROV; • A compass heading lock mode allowing the vehicle to automatically maintain a compass heading set by the pilot; • A thruster input hold function allowing adjustable forward thrust without continuous pilot input (i.e. “cruise control mode”)...
