Using hydraulics cylinder and hydraulic motor in the A frame and which it provides means to launch and recover ROVs.

• A. LARS
• B. Manipulators
• C. Cutting tools
• D. Thruster

Answer: (A)

Launching and recovering an ROV from a vessel is accomplished with a Launch and Recovery System. In an A-frame setup, hydraulics provide the essential motion: a hydraulic cylinder delivers linear extension to lower or raise the cradle, while a hydraulic motor drives the winch that pays out or reels in the tether as the ROV is deployed or recovered. This combination enables controlled, safe movement of the ROV through the water and back aboard, with the cradle guiding and supporting the vehicle during handling. The other items listed are components of the ROV itself—manipulators for grabbing or manipulating objects, cutting tools for operations, and thrusters for propulsion—not the launch and recovery mechanism.
