Summary: The ROV Manual: A User Guide for Observation-Class Remotely Operated Vehicles is the first manual to provide a basic ""How To"" for using small observation-class ROVs for surveying, inspection and research procedures. It serves as a user guide that offers complete training and information about ROV operations for technicians, underwater activities enthusiasts, and engineers working offshore. The book focuses on the observation-class ROV and underwater uses for industrial, recreational, commercial, and scientific studies. It provides information about marine robotics and navigation tools used to obtain mission results and data faster and more efficiently. This manual also covers two common denominators: the technology and its application. It introduces the basic technologies needed and their relationship to specific requirements; and it helps identify the equipment essential for a cost-effective and efficient operation. This user guide can be invaluable in marine research and surveying, crime investigations, harbor security, military and coast guarding, commercial boating, diving and fishing, nuclear energy and hydroelectric inspection, and ROV courses in marine and petroleum engineering.
